How To Get Healthy? Start With More Greens!

2020

Tomatoes, A Tribute to My Mother, Takotsubo, and A Tactic Called “Just One Leaf”

Open any food or garden section in print or online sites, and you’ll see articles on the benefits of eating healthy greens and colorful foods. Today, I’ll show how you can start adding leafy greens to your diet without being terribly inconvenienced. And I’ll mention how it might have saved my life.

How exciting—the first two ripe tomatoes of the season came off the vine this morning. And there’s some beautiful ‘Genovese’ basil begging to be picked. So, you can guess what’s for dinner tonight:

Tomato-Basil Salad!

It’s so easy to prepare:

ripe tomatoes, cut into chunks, including the juice
freshly picked sweet basil
cucumber, cubed or sliced
thinly sliced onion
mozzarella cheese
Italian oregano
extra virgin olive oil
red wine vinegar
salt and pepper

Mix it all together, and enjoy with some good bread for dunking (optional). This salad hits the spot when it’s hot, for one person or for a crowd.

But First, A Tribute To My Mother

My mother and I have lived together for the past 7 1/2 years. Many of the ripe tomatoes from the garden ended up in tomato-basil salad, a summertime staple for this family of Italian descent. How we loved our eggplant parmigiana, vegetarian lasagna, manicotti, and stuffed artichokes! How we loved to eat! In so many of our memories growing up and growing older—the holidays with family, sitting around the table for hours—good food always featured prominently.

Early last month, I had notified my family that there wasn’t much time left for Mother. So, my siblings prepared for a visit, and my sister sent an early Mother’s Day bouquet of white roses, purple statice, and baby’s breath—very much appreciated.

One brother came from out of town and spent the day with us, recalling some of the funnier family moments. We had ravioli and Easy Broccoli One for dinner. I’m a firm believer in the health-giving powers of broccoli, so I prepared it one way or another quite often. I’ve joked before about broccoli being Mother’s “favorite”, and she did too. “Oh, what a surprise—broccoli … … thank you…” She ate well that evening, better than any day in recent months.

But, the next morning, her time had come. She passed quickly and peacefully while I spoke to her and with 9-1-1. A friend said that the sense of hearing is the last to go, which gives some consolation, knowing she might have heard me.

“Don’t Forget To Watch Bob Ross”

My mother lived for 95 years, leaving behind a brood of 4 children, 11 grandchildren, and 8 great-grandchildren. Photographs of family reunions, grandkids, and the great-grandchildren sat in a neat pile within reach of her favorite chair. Mother often lamented the fact that the family had scattered all over the country and couldn’t get together more often for the holidays.

She enjoyed driving her little Toyota, running errands nearby, right up until early last year. Have Rollator, will travel! When speaking with friends on the phone, her humorous references to the “joys” of growing old brought a smile to my face. Humor is the best medicine.

She was an artist, as a few relatives are and were, and I’m inclined to pick up the brush myself and give it a whirl (photo, above—a detail from one of her paintings). I don’t have to wonder very long where this stubborn streak of independence or rebelliousness came from…or my love of animals and of all nature. So, maybe some of her talents run through my veins as well. I hope so. Sure, we had occasional disagreements, but the foundation of our commitment to family was unshaken.

Stress, Nevertheless

People often speak of “a good death”, and, in all honesty, we could not have asked for a more peaceful departure. The next few days, though, taught me that the body reacts to experiences differently than the brain does. While my brain thought I was handling this major event quite calmly, my body had a different opinion.

Soon after Mother had died, the four of us siblings got together, telling stories while dividing those belongings she had gathered—and loved—for nearly a century. Whether it was the distress of a misplaced ring or the stress of her passing, I ended up in the hospital three days later.

With Covid concerns at the time, I drove myself to the emergency room, with moderate chest pain. My mother had had serious heart disease for a few decades but was able to function fairly normally with assistance from her medications and her cardiologist. But I had to wonder: is it my turn? My blood pressure had soared to a dangerous level, so I was admitted.

After several tests over the next two days, the doctors did not find any “separation of the layers” or blockages in my coronary arteries, and the valves were working as they should. But my blood pressure stayed very high. Blood tests also showed the presence of those markers when the heart has been impaired.

One consequence of blood pressure this high could be stroke, and my release from the hospital was contingent upon healthier numbers. A few medications attempted to normalize the readings, and one in particular did an astonishingly good job of lowering those numbers to 79/51. Won’t be taking that one again! (It was hydralazine.)

Takotsubo Two!

Almost 4 years previously, I woke at 4:00 in the morning with a stabbing pain in the center of my chest. Considering our family history, I thought it could have been a heart attack. The ambulance came, the EMT recorded my blood pressure at 275/135, and off to the hospital I went.

The usual tests were performed, and a cardiologist administered a catheterization to trace the blood flow in and around my heart. The score: although I was lightly sedated, his words indicating that I had “the arteries of a 20-year-old” were music to my ears. After decades of being more than careful with diet, I wondered if I had needlessly missed out on all those BLT’s, pasta, and toffee cookies.

On the day of discharge from the hospital, another cardiologist explained what happened. He said one of the lower chambers of the heart (the left ventricle) had ballooned out, giving it an odd outline. Good news—I would fully recover but would experience fatigue for a few months. He and a dietician recommended continuing with a diet heavy in healthy leafy greens and losing some weight.

What’s Takotsubo?

That’s when I first heard the term “Takotsubo”. This Japanese word means “octopus pot”, a reference to the interior shape of the affected ventricle. The syndrome was first described in Japan in 1990. More than 90% of the cases involve women, aged 58 to 75 (check, and check).

So, it happened again. This time, though, stress was very much the precipitating cause. Often called “broken heart syndrome” or “stress-induced cardiomyopathy”, a sudden life-changing event, such as the loss of a loved one, winning a lottery, being assaulted, or a car accident, can trigger Takotsubo syndrome. Most cases are due to a stressor, but around one-fourth occur for no discernible reason.

The ring, by the way, was found after my return from the hospital.

Add Just a Little More Green

Greens from the garden: green onion, mustard greens, dinosaur kale, arugula, ‘Red Russian’ kale.

I’m not a nutritionist. All I know is what I’ve read or heard over the years and observed from family members. The purpose for writing this article is simply to credit how changing my diet many years ago might have prevented a stroke or a heart attack, possibly saving my life during these two bouts with Takotsubo. (Even though the death rate from this condition is fairly low, other contributing factors and our family history concerned me.) You, too, might decide to make some improvements in your own family’s habits.

Take from it what you want—and take heart—this doesn’t have to happen overnight. I encourage you not to wait, however, until after you’ve gotten your first stent to make some changes. We did eat pretty well growing up. But, in retrospect, we consumed more carbohydrates than is currently considered healthy, and certainly fewer healthy greens.

Simply adding fresh leafy greens to soup, a smoothie, sauces, salads, a stir-fry, store-bought pizza, or rice and pasta dishes is a great step toward a healthier future. Grocery stores offer a much wider variety of greens than they did decades ago.

Growing your own plants from seed opens up so many more options. And you can’t beat the convenience of walking a few feet out the kitchen door to pick fresh healthy greens for today’s omelet or soup. Many of them can be grown in pots on the deck or the balcony if you don’t have garden space.

At the end of this article is a list of links to posts I’ve written about growing and using greens. You’ll notice the frequency with which I refer to “the brassicas” (broccoli, cabbage, cauliflower, collards, kale, etc.), the source of the most beneficial and densely packed nutrients.

Try this: a simple egg salad sandwich, on rye, made with one hard-boiled egg, mayonnaise, green olives, chopped dinosaur kale (a brassica, and super healthy), and topped with lettuce. Add chopped onion, if you like. No salt needed. I usually serve it on a bed of lettuce or mixed greens, without the bread. You can do the same with tuna or chicken salad. Adding “Just One Leaf” of kale significantly elevated the nutritional value.

Greens In Small Steps

Easing into dietary improvements by making small changes might meet with less resistance from your family. Perhaps starting a garden and letting the kids participate will get them engaged.

Children who help care for a garden are more likely to eat what they harvest. Start with easy crops, such as dinosaur or ‘Red Russian’ kale, collards, lettuce, a cherry tomato, Swiss chard, and radishes. Mustard greens are colorful and fast-growing—‘Florida Broadleaf’ has mild mustard flavor (and it self-seeds), while ‘Scarlet Frills’ offers a spark of heat and spice. These are easily grown from seed.

nasturtium 'Alaska', edible flowers and greens

Nasturtium ‘Alaska’, easy from seed, needs darkness for germination.

If your garden has good, rock-free soil, sow a pack of carrot seeds, and thin them properly. You’ll find traditional orange carrots and also nearly white, yellow, red, and purple varieties. ‘Rainbow’ is a blend of colors. Watch how excited your children will be when they harvest their buried treasure! Try growing ‘Adelaide’, a miniature carrot, in 6″ pots. Delicious, and so cute.

A customer at the farmers’ market in Rockville MD added chopped ‘Alaska’ nasturtium flowers and leaves to his grilled hamburgers. Each bite revealed a different combination of colors. Every year, he came to the market for his “burger-fetti” nasturtiums. Look for ways to introduce greens and colors at mealtime to make it fun.

Just One Leaf

As the first bits of greens have been accepted, keep adding more leafy greens (Just One Leaf or two at a time) and cutting down on some of the carbohydrates and animal proteins. Get creative in the kitchen. Soon, you’ll notice a boost in energy and might reach for a handful of nuts and a cup of green tea for a mid-afternoon snack, packed with vitamins and minerals, fiber, phytonutrients, and protein, instead of a chocolate doughnut.

Unless it’s absolutely necessary, I never peel fruits and vegetables. The skins have more antioxidants, fiber, and vitamins than the flesh. So, I don’t peel apples, peaches, carrots, cucumbers (some are less bitter, such as ‘Diva’), eggplants, sweet/white/pigmented potatoes, tomatoes, or zucchini.

But I Miss My…

Once in a while, it’s perfectly okay to indulge in an ice cream sundae or Christmas cookies. But you might find that the desire for such decadent treats decreases as your interest in healthy foods increases. Sugar is addictive!

Over time, adding healthy greens to the spaghetti sauce, a stir-fry, or the morning smoothie will become second nature. Not doing so might make you feel as though you’re missing out.

Eat Your Colors

red and yellow peppers, with healthy pigments

Ripe sweet bell peppers.

You’ll discover a new appreciation for incorporating colorful greens and vegetables into your salads. Deep green, purple, red, orange, and yellow pigments are filled with healthy antioxidants and other nutrients.

These plant pigments help prevent many major illnesses, including cancer, heart disease, type 2 diabetes, age-related macular degeneration, inflammation, premature aging, and other disorders. Understand that they will help prevent illness. Do your best to eliminate other risk factors, too, and you know what they are.

Ask your doctor if you have any dietary concerns. While it is true that spinach, Swiss Chard, and beet greens (in the Amaranthaceae family) are high in oxalates, we need to examine the relationship between oxalate content and kidney stones. Some nutritionists believe that including more meat in the diet lowers the blood pH level, while a primarily plant-based diet raises the pH and lowers the incidence of kidney stones. Kale, incidentally, has extremely low levels of oxalates.

Another issue is how eating large amounts of certain raw brassicas can affect the thyroid gland, so, again, ask your doctor.

Add these to your salad and you’ll soon say good-bye to pale iceberg wedges:

deep green and red lettuces
purplish ‘Red Russian’ or blue-gray dinosaur kale (brassica)
baby beet greens (more nutrients than the roots)
turnip greens (brassica)
arugula (brassica)
spinach
Swiss chard
radish (brassica)
shredded red cabbage (brassica)
Asian greens, such as tatsoi, mustard, mizuna, napa cabbage, ‘Tokyo Bekana’ (brassicas)
broccoli leaves, or stems and small heads of ‘Happy Rich’ (brassica)
purple and orange carrots (heated carrots have more available antioxidants)
ripe lunchbox sweet pepper (red, orange, yellow; orange bell peppers are extremely high in zeaxanthin, an antioxidant that’s good for the eyes)
tomato, cucumber, green onion, celery, cooked button mushrooms, lightly roasted pecans, feta or bleu cheese, fresh basil, avocado, a hard-boiled egg, kalamata olives
and a simple homemade dressing: extra virgin olive oil, red wine vinegar, water, fresh minced garlic, some herbs (small amounts of Italian oregano, and maybe thyme and sweet marjoram) and lemon if you like, some Dijon mustard, and salt and pepper

Colorful lettuces.

Daffodils and Birdsong: The Signs of Spring

Feb10

2020

cherry trees and daffodils for early spring color

These cherry trees started blooming in January.

Warming Up: The First Daffodils

Early Daffodils

Around the corner, white daffodils bloomed incredibly early—on New Year’s Day! A neighbor’s hellebore, or Lenten rose, was in full flower at the same time, and the local cherry trees (photo, above) have been covered in pink for weeks starting in January. Forsythias are beginning to flower, and the bulbs are coming up thick and healthy after all this rain.

Daffodils in February, Cane Creek Park, Waxhaw NC.

At some point in the early months of the year, seasonal signals indicate the coming of warmer weather to this USDA zone 7b (borderline 8a) area. Flowers popped open this morning that weren’t there yesterday. The grass is greener. Songbirds are more vocal than they were last month. And on blueberries and other shrubs, leaf and flower buds are plumping up, preparing to push those bud scales aside. Mother Nature puts on quite a show in spring, my favorite season.

Maybe there are other indicators that you look for in your landscape. First snake sighting? Migrating birds flying north? Moths flitting around the porch light at night?

The National Oceanic and Atmospheric Administration (the National Weather Service) predicts a greater chance for above normal temperatures over the next 3 months (spring, 2020). This prediction is for the southwest U.S., across the south, and partway up the Atlantic coast. Northern Alaska has a high probability of higher than normal temperatures. Check NOAA’s map for your region’s long-term temperature and precipitation forecasts.

Punxsutawney Phil

A woodchuck.

This year, Punxsutawney Phil, the prognosticating rodent, concurred with NOAA’s forecast, calling for an early spring. Phil would be wise to check with NOAA every year before making his Groundhog Day predictions; his accuracy is below 40%. And there are only 2 possibilities: shadow, no shadow!

This tradition, celebrated in the United States and Canada, dates back to 1887, and is a fun, although not terribly accurate, test that helps build anticipation for spring.

Phil is one of several groundhogs, or woodchucks, around the country called upon to presage the coming weather. After being awakened at dawn on February 2, if he does not cast a shadow, the tradition dictates, spring will come early. The alternative is six more weeks of winter. Well…six weeks from Groundhog Day falls in mid-March. So, mid-March (“six more weeks of winter”) and early spring, as I see it, are the same thing. I guess you’d have to define “early”.

**What? Snow?!**

Squirrel takes all.

For a couple of hours on Saturday, I was mesmerized by a wet snow. We haven’t had any snow here this winter, and I just love to watch it. I also have to go outside and feel it. Then a beautiful Cooper’s hawk came for a visit. The question is…would he swoop down for one of the birds at our back yard bird feeder?

Earlier, I put outside a spoonful of peanut butter, suet, more seed, and whatever we had collected in the “bird cup”. This container sits on the kitchen counter, and is where we put crumbs, withered blueberries, strawberry tops, older peanuts, and anything else that might interest the birds. These morsels go into the box (photo, right) near the bird feeder, and the birds share this bounty with squirrels and various marauders in the night.

I didn’t cover the emerging bulbs to protect them from snow. Daffodils, hyacinths, and wood hyacinths get through this time of the year just fine with no help from me.

The Birds are Changing Their Tune

A male northern cardinal.

The local birds recently have been singing in what I call “the key of procreation”. When the birds change their tune, spring isn’t far behind. There’s something almost magical about birdsong at this time of the year. I love to hear it.

Northern cardinals, Carolina wrens, tufted titmice…they all have spring calls that are distinctly different from chirps and melodies sung later. These calls help unite young breeding pairs and reunite mated partners after a separation.

The hawk showed up, though, and everything suddenly went very quiet. He sat in the trees for two hours, his plumage camouflaged by the browns and grays of tree trunks and branches. But he did not make an attempt to catch lunch on the fly.

There are plenty of hiding places for the birds, and they were aware of the hawk’s presence. Birds warn each other of this kind of threat by issuing alarm chirps.

Daffodils and Deer

Some of the yellow daffodils on the berm are beginning to bloom, although recent wind (a tornado, actually) laid them nearly flat to the ground. I planted these bulbs several years ago, and it’s always a pleasure to see their green shoots emerge in January or February. But this winter, they began rising in late December.

Deer resting among the untouched daffodils.

Deer regularly pass by them as they travel the berm, but they never eat them. All parts of daffodils are poisonous to warm-blooded animals. But bees and other pollinators looking for pollen and nectar when not much is available appreciate the early blooming bulbs, brassicas, and fruit trees.

The bulbs’ foliage is the only ground-level greenery in that area for now. It’s a small thrill to see these bulbs thriving up there, and a bigger one watching the deer walk around them! (***Update***: Several deer rested all morning on the berm, among the blooming daffodils. They sniffed but didn’t eat the flowers. Feb. 14, 2020.)

If deer have eaten every one of your cherished tulips, you’ll have greater success with daffodils.

The Edibles

Miniature broccoli ‘Aspabroc’.

We had a very mild winter. True—it’s not over. But I covered the broccoli, the kale, and the green onions on only a few nights. Although these plants can tolerate temperatures into the teens, I prefer to protect them below 25°F. This keeps their foliage in great shape. And the green onions would be very difficult to pull from frozen soil!

The microclimate created by the corner between the house and the shed keeps the deck a few degrees warmer than out in the open. Maybe there’s a sunny corner where you can tuck in a few pots of winter greens. Or you might be able to dig a small garden next to a south-facing brick wall.

It won’t be long before you’ll see small pots of hardy cool season greens showing up at the garden center. You can get a head start and plant seeds indoors now for many of these plants.

Mustard greens from last year’s spring garden volunteered in the front garden by mid-summer. The Italian parsley is growing large, and, recently, I picked a few substantial stems of ‘Aspabroc’ miniature broccoli for dinner. The ‘Arcadia’ broccoli heads were harvested in December, but side shoots will provide additional harvests for the next 2 or 3 months. Broccoli leaves are edible, too, and highly nutritious.

Frequent heavy rainstorms washed away much of the soil’s fertility, so I fertilized the pots a few times through the winter. Without it, the broccoli heads would have been much smaller and the greens…well, less green. When the temperatures were more moderate, I used SeaPlus (seaweed and fish emulsion). In cooler soil, though, when microorganisms aren’t active, a soluble synthetic fertilizer works better. Microbes break down the nutrients in organic fertilizers and make them available to plant roots, but they’re dormant in cold soil.

: Mustard greens ‘Florida Broadleaf’.

: Dinosaur (‘Lacinato’ or ‘Toscano’) kale.

: Green onions, with a few more sets to be planted.

A Few Simple Chores In the Garden

As you make your rounds through the garden, note the chores that need to be done. Maybe the mulch needs a refresh by simply turning it over with a garden rake. Are chickweed and other winter-germinating weeds about to go to seed? Don’t let them! Just one seedpod can turn into dozens of weeds next year.

Yellowed leaves caused by shade.

A thick blanket of last year’s fallen leaves will block light from the daffodils and hyacinths emerging from the ground. Although the shaded spears look yellowed now, they’ll quickly green up when exposed to sunlight. Take some of the leaves to the compost pile, or to the brush pile where insects and other animals find refuge in inclement weather.

Have you noticed the first bulbs emerging from your lasagna pot (photo, above)? Be sure to water them if they’ve been under cover, and give them sunlight to green up etiolated foliage. Gardeners in colder climates still need to protect the pots from alternate freezing and thawing, which could kill the bulbs. Their roots don’t have the benefit of insulation provided by the mass of soil around them, as do bulbs planted in the garden.

: Potted green onions.

: Iberis with flower buds.

: Astilbe sprouting in a pot.

: ‘Kopper Kettle’ Itoh peony.

: Bridal Veil spirea.

: ‘Monstrueux de Viroflay’ spinach seedlings.

Even though it’s still chilly, these stirrings in our gardens point to nature’s own impatience to get the show on the road. So, bundle up, and take the kids, the dog, or your thermos to the garden. For me, the thought of going out in the cold is worse than actually being there. Besides, if you stay indoors, you could miss the first act!

Starting Seeds for Cool Season Greens

Feb24

Starting Seeds for Cool Season Greens

The coldest part of winter has passed for most of us, and it’s time to start seeds for cool season greens. Late winter transitioning to spring is my favorite time of the year. That’s when I start seeds for early harvests. This article covers details for growing some of the early greens, particularly spinach and the brassicas. On Page 3 is a recipe for a veggie omelet, an easy way to get more greens into the diet.

If the garden were bare, I would have started seeds a few weeks ago. But the greens in the vegetable garden continue to offer harvests. Unfortunately, the “list of wants” from the seed catalog is far more extensive than the garden’s square footage can accommodate! It’s time for the last harvest of collards for soup; that’ll open up some space.

While we’re harvesting established cool season greens, I’ll start several new crops indoors. These plants will be plugged into the garden as space opens up. But the seedlings will not be kept in their little pots very long; this stresses the plants and causes them to bolt, or to flower prematurely. (Photo, above: dinosaur kale germinated at night; it will green up in the sunlight.)

The First of the Cool Season Greens: Spinach

Young spinach ‘Monstrueux de Viroflay’.

I would have sown spinach directly into the garden by now, but we’ve had a long run of chilly rain. The soil is so wet that it’s doubtful any seedlings would even be tempted to germinate. At this time of the year, pay close attention to the weather forecasts. Conditions could deviate considerably from the averages.

It’s not good to dig in soil this wet anyway. That would drive out air spaces and ruin the tilth of the soil by compacting it.

As temperatures begin to moderate, slugs come out in force and will decimate any seedlings that dare to grow in this weather. Rain: good for slugs. Sluggo: bad for slugs! Organic Sluggo pellets attract and kill slugs and snails. This version of the product contains materials (iron phosphate) that add nutrients to the soil. Check the label, though; Sluggo has other products with added ingredients. The organic option is safe to use around the edibles.

Spinach From Seed Is Easy!

Spinach germinates readily, from 50°F up to the mid 70’s (soil temperature), as soon as the ground can be worked in late winter or early spring. For better chances of success, choose varieties that are disease resistant and slow-bolting. In well-prepared soil, spinach is one of the easiest crops to seed directly into the garden.

Prepare the bed by incorporating 2″ to 3″ of compost and/or aged manure into the top 5″ of soil. Spinach prefers soil pH near neutral, from 6.5 to 7.3. A soil test will indicate how much lime, if any, should be added to raise the pH.

For baby leaf harvest, sow the seeds thickly in a patch, about 1″ apart. For full-size leaves, space the seeds a few inches apart, with rows 8-10″ apart. Crowding the seeds too closely or poor soil will result in a disappointing crop.

‘Monstrueux de Viroflay’

There’s a wonderful variety called ‘Monstrueux de Viroflay’ (photos, above and below), a French heirloom dating to 1866. It grows very large for spinach, up to 20″ tall with 10″ leaves, and should be spaced several inches apart.

Viroflay, or Monster, as it is often called, is lower in oxalic acid, or oxalates, than other spinach varieties. It might be acceptable for people with health concerns that prohibit spinach consumption. Check with your doctor.

Keep the soil moist and add organic fertilizers, such as fish emulsion, Sea-Plus, or earthworm castings, every 2 weeks. In cold soil, however, liquid synthetic fertilizers high in nitrogen work better than the organics. Microbes in the soil break down organic material and make those nutrients available to plant roots. But microbes are dormant in cold soil, so they can’t perform this vital service. They’ll become more active as the soil warms up in late winter or early spring.

‘Monstrueux de Viroflay’ spinach seedlings.

Spinach Bowl

Another option is to sow seeds directly into a 14″ wide, 6″ deep bowl filled with fresh potting soil (photo, above). The pot has drainage holes. Portability allows me to bring the pot indoors on especially cold nights while the cool season greens are beginning to germinate. And moisture levels can be carefully monitored.

Since the sappy crooked pine tree that shaded the deck from afternoon sun has been cut down, conditions on the fenced-in deck are more favorable to growing vegetables in containers.

Fill the pot with potting soil to within an inch of the rim. Simply scatter seeds on the surface, a couple of inches apart for smaller varieties and a few inches apart for Viroflay. Cover with another 1/3″ to 1/2″ of soil. Water…and wait… Spinach’s two seed leaves, the cotyledons, are easily differentiated from other seedlings by their long narrow shape. Thin as necessary; you can eat the culls.

Don’t neglect fertilizing potted greens. Rain and irrigation quickly wash nitrogen out of the soil.

Harvesting Spinach

Spinach.

Harvesting the crowns begins within 4 or 5 weeks, depending on weather and soil fertility. Pick individual leaves at any age, allowing the central growing tip to continue producing new leaves. Or cut the entire plant at the soil line before flower buds begin to grow.

By sowing new crops of spinach every week or two, you’ll have continuous harvests of spinach, as long as the weather favors growth.

Spinach quickly bolts, or goes to flower, at temperatures above 75°. Dry or nutrient-poor soil stresses the plants. And spinach will flower prematurely if the plants are stressed by growing too close together.

Harvest the entire plant if you notice flower buds forming. Cutting off the flowers will not stimulate spinach to grow a new bunch of leaves. Instead, start more seeds.

Use spinach steamed as a side dish, or in sauces, soups, smoothies, salads, pasta dishes, or an omelet.

And Then the Brassicas

These microgreens are mostly brassicas.

The Brassicaceae family is a huge group of edibles. It includes arugula, broccoli, Brussels sprouts, cabbage, cauliflower, collards, kale, komatsuna, mizuna, mustard greens, pac choi, radish, tatsoi, turnip, and others.

All members have similarly notched seed leaves, or cotyledons. Those are the first two heart-shaped leaves to emerge from the seeds (photo, above). Because the seed leaves are already formed inside the seed, the little plant can begin photosynthesizing—and feeding itself—immediately upon germination. True leaves, which develop after the seed leaves, are also similar for most of the cruciferous vegetables. That’s why it’s important to label your pots so you can distinguish “this” seedling from “this other similar looking” seedling.

Include On the Label:

the name of the crop (dinosaur kale)
the name of the cultivar (‘Black Magic’)
the date of sowing (brassicas germinate in less than a week if sown indoors)

Store leftover seeds in their original packets, and make sure the cultivar name is included on the label. Store in a cool, dry place, such as the refrigerator. Most seeds of cool season greens are viable for 2 years or so. If not already indicated, mark the year of purchase on the packet.

It’s helpful to keep a record of the varieties you’ve tried and liked or disliked. Include how you started the seeds (in 4″ pots or cell-packs, under lights, directly in the garden), the dates you seeded and transplanted, and the weather conditions. Include notes on what was successful and what wasn’t, and possible explanations. Did the seeds germinate and then keel over and die (damping-off disease)? Did critters eat your cool season greens as soon as they started growing? Should the seeds have been started earlier? Or later?

There are successes and failures in every gardener’s life. Being able to pinpoint the reasons for a disappointing crop will enable you to be more watchful or to try a different approach next time. Check with your local cooperative extension office, through state land-grant colleges and universities, for advice. Failure is a learning experience, not a reason to stop trying!

Damping-Off

Damping-off disease can appear soon after germination. Sometimes, diseased seedlings don’t even appear above the soil, looking as though the seeds didn’t sprout at all. The small seedling develops a narrowed brown spot on the stem. Then the top of the plant falls over, and the seedling dies. This is caused by several species of fungus, whose spores are in the air, in the soil, in the water, or on the seeds themselves.

Damping-off often accompanies:

poor air circulation
high humidity
crowding
low light
low temperatures
reusing old soil
and overwatering

Space the seeds farther apart, run a small fan nearby, water in the morning, and increase the temperature and light levels if they’re low.

The first time I used the organic biological fungicide called Actinovate, life became a bit sweeter. It is costly, but a much safer option than chemical fungicides. And, with the number of seedlings I grow each year, a wise investment. Make up a small amount of the solution when needed and apply from a spray bottle or a small watering can when sowing the seeds and as soon as the seeds germinate. Always exercise caution when using sprays, and read the labels.

Caterpillars on Cool Season Greens

When the weather warms up in mid- or late spring, you’ll notice butterflies and moths flying around your cool season greens. How nice, you might think. But those lovely insects are on a mission, and that mission is to find suitable plants on which to lay their eggs.

: Cross-striped cabbageworm, becoming more common here, on mustard greens. Expect several generations per season. Look for clusters of white woolly eggs.

: Broccoli leaves eaten by caterpillars.

Most of the brassicas are targeted by the female:

Cabbage Moth (or Diamondback Moth)
Cabbage Looper
the velvety green Imported Cabbageworm (also called the Small White Butterfly or Cabbage White Butterfly—white with black markings). Look for them lined up on the leaf’s midrib.
Cross-striped Cabbageworm (fine black stripes across the back, yellow stripe on the sides).
A few other species target particular brassicas or are limited geographically.

Here in my North Carolina garden, the 1¼” long Imported Cabbageworm has been the most commonly seen caterpillar on the brassicas. It is well-camouflaged in the green foliage. But for the past couple of years, populations of the Cross-striped Cabbageworm have been increasing. They’re especially pesky when lodged among the broccoli florets. Sometimes I don’t see them until I begin cutting the broccoli (just remove them). Inspecting the produce and spraying Bt regularly takes care of that.

Eggs hatch in a few days to a week, and immediately get to work chewing little holes and then bigger holes in your broccoli, kale, and other brassicas.

Harlequin bugs on cabbage

Another insect feeding on brassicas is the black and orange harlequin bug (photo, above). I squish them when I see them, although they’ll see you approaching them and will try to hide. They cause whitish blotches and distortions in the foliage.

Bacillus Thuringiensis (Bt)

As soon as you notice the white moths and butterflies flitting near the brassicas, it’s time to get the sprayer bottle ready. The imported cabbageworm is the larval stage of a butterfly and the one you’ll see in the daytime. The other caterpillars are moth larvae and are active at dusk or at night.

Mix up a solution of Bt, Bacillus thuringiensis, available from the garden center. Dipel and Thuricide are brand names for Bt. It doesn’t take long for these voracious little caterpillars to inflict considerable damage to your plants, so don’t delay.

Spray both the upper and lower surfaces of the foliage, occasionally agitating the solution. Begin spraying a few days after first seeing the moths, or certainly when you see holes appearing. Set the sprayer nozzle to a very fine spray; larger drops of water will bead off the waxy foliage. One or two drops of dish soap in the sprayer will help the solution stick to the foliage if you can’t get a fine spray.

It washes off in the rain, but any Bt clinging on the reverse (bottom leaf surface) might be enough for the current batch of caterpillars. Spray the brassicas every 5 to 10 days, as long as the insects are active.

How Does Bt Work?

Bt is a naturally occurring bacterium that disrupts the caterpillar’s digestive system when ingested. The insects stop feeding immediately and die within a day or two. Spray as soon as you notice them because young caterpillars are more susceptible to Bt than older caterpillars.

Bt effectively rids the garden of moth and butterfly larvae, including swallowtails that eat parsley. Although they won’t bother your broccoli, black swallowtail larvae feed on parsley and its relatives in the Apiaceae family, including dill, cilantro, and bronze fennel.

The tradeoff? Fewer moths and butterflies, but more undamaged produce. I enjoy watching the black swallowtail butterflies, though, so I plant the large perennial bronze fennel for the caterpillars picked off the parsley and dill. Bt targets larvae of moths and butterflies, and nothing else.

After picking the crops, I sometimes let the caterpillars feast on the remains. Those caterpillars might feed another brood of baby birds or green anoles at that time of year. Once cold autumn weather has settled into the area, these caterpillars will no longer be around to bother the fall crop. Autumn is another delightful time to garden.

Bt is perfectly safe to use on edibles. Use up the diluted solution within a few days. Store Bt in a cool location out of the sun. Buy a small fresh bottle every couple of years, as this is a live organism, not a chemical.

Spring Is Coming: The Earliest Signs

Signs of Spring

Early Spring Bloomers

The birds are singing their spring songs (I love waking up to that), and the delicate sweet fragrance from early blooming trees floats on the breeze. Spring-flowering bulbs of all sorts are pushing up emerald green spears, and some of the daffodils are coming into full bloom.

A few varieties of cherry trees, with their characteristic horizontal banding of lenticels on the bark, are blooming now, in late winter. Lenticels are pores that allow gas exchange between the plant and the atmosphere. Autumn cherry trees (Prunus subhirtella ‘Autumnalis’) in neighborhoods I sometimes drive through have been flowering non-stop for months. They don’t have the short, showy burst of a ‘Yoshino’ cherry, but any flowers on a winter day are a welcome sight.

Saucer Magnolia.

Neighborhood saucer magnolias (Magnolia x soulangeana) just started blooming with their pinkish-purple cup-shaped flowers. This can be a tricky species; an untimely frost can turn all the open flowers brown in a flash. Look for a later-blooming cultivar to plant in spring, plant it in a protected location, or take your chances! You can now find a wider range of flower colors (yellows and purples) thanks to modern breeding.

Star magnolia.

The related star magnolia (Magnolia stellata) is another late winter or early spring flowering tree. Its blooms are white or pink, depending on cultivar, shown against silvery gray bark.

Magnolias prefer full sun and moist, well-drained soil. They dislike root disturbance, so situate them where you won’t be digging around the root system.

Their smaller size recommends them to areas of the property where large trees would be out of place. When designing your landscape, always consider the mature height and spread of a tree’s canopy.

The ‘Yoshino’ Cherry For Spring Flowers

‘Yoshino’ is a hybrid between Prunus speciosa and P. pendula, and was first introduced to Europe and North America in 1902. It grows in USDA Zones 5-8, to a height of about 35′ or 40′. Plant taxonomists proposed that the true scientific name should be Prunus x yedoensis ‘Somei-yoshino’. (The lower-case “x” after the genus Prunus signifies that this variety is an inter-specific hybrid; “yedo”=Tokyo.)

There was some doubt, now resolved, whether this variety was distinguishable from the Jeju flowering cherry. ‘Yoshino’ is genetically different from the King cherry, now named Cerasus x nudiflora. The Jeju cherry is an endangered species, with only a few hundred specimens remaining on Jeju Island.

If you’re planning a trip to the U.S. capital, try to schedule it when the ‘Yoshino’ and other varieties of cherry trees are in full bloom around the city, and particularly at the Tidal Basin (photo, below). Just gorgeous! Much has been written about Tokyo Mayor Yukio Ozaki’s generous gift of thousands of cherry trees back in 1912, meant to celebrate the growing friendship between Japan and the United States. See if you can find a live cam of the Tidal Basin’s cherry trees as they begin to bloom.

cherry trees, Tidal Basin, early spring bloom

The Washington Monument and cherry trees around the Tidal Basin.

One year, my daughter, Brynn, marched with her high school band in Washington D.C.’s National Cherry Blossom Festival parade. The festival is an annual commemoration of Japan’s gift and a celebration of spring. Check with the National Park Service for the progress of the trees’ buds (posted about March 6), because the two events—the festival and the trees’ peak bloom—often don’t coincide.

In the Landscape

I planted a ‘Yoshino’ cherry in a customer’s garden, behind a pergola that the owner had built at the end of a large pond installed in the family’s back yard. Their concern that it would grow too slowly for them to enjoy the flowers and the full stature of the tree was dispelled after only a handful of years. This is a fast grower, with smooth maroon bark and attractive horizontal branching. Pink flower buds open to clouds of white to pale pink blooms. For many gardeners, ‘Yoshino’ cherry trees are synonymous with spring.

It’s no wonder cherry trees are held in such reverence in Japan and in gardens around the world. They are perfect complements to a pergola, a pond, or an old barn, and often feature prominently in Asian-style naturalistic garden design. Although the ‘Yoshino’ cherry is not the longest living ornamental tree, there are some gnarly 100-year-old specimens in Washington, D.C.

I used to cut budded branches from a tree in our back yard, and force them in a vase indoors. Use stems with buds that have visibly swelled in anticipation of spring.

Another show takes place when all the petals fall to the ground, like pink snow. It’s a lovely sight, and the flowers blow away or disintegrate after a few days. They will stick to the soles of your shoes, so consider that fact if you want one near the house or a frequently used sidewalk.

Easy Broccoli One and Easy Broccoli Two: Recipes

Aug1

Fresh broccoli crowns.

The route from “farm to table” can’t be any shorter than if it starts in your own back yard. Here are two broccoli recipes that take minutes to prepare, and might convince you to grow some plants this fall. 2 or 3 servings.

Easy Broccoli One:

Use a medium size pot, with a lid. Add 2 or 3 Tbsp. water.
Broccoli: Rinse a fresh crown, about 5″ in diameter. Remove tough, thick stem. Cut head into bite-size florets; remaining tender stems should be cut smaller. Some people don’t use the stems, just under the head, but they’re perfectly edible, as are the leaves. Place florets into the pot.
Mushrooms: Wash and trim stems of a few white button mushrooms, slice, and add to pot.
Cover, heat up the pot, then lower temperature, to steam the broccoli and mushrooms. Mix once or twice. Don’t overcook; heat enough to turn broccoli to a bright dark green color, which takes only a minute or two. Overcooking this vegetable makes it soft and smelly.
Finely mince a clove of garlic, and add to a small butter pot (ours is 3″ in diameter, stainless steel) with 1 tsp. butter and 1 or 2 Tbsp. olive oil. Heat this pot over low to medium heat until garlic is a light golden color. (Burned garlic tastes terrible. If you have to start over, that’s better than using the burned garlic.) This step might take a bit longer than cooking the broccoli; I start this one first.
Drain water from the broccoli pot. Add to the broccoli the contents from the garlic pot and a dash of salt. Mix and serve.

This is a great, fast side dish by itself. Or use it over some enriched pasta, with a little more oil and grated Romano cheese. Photo, below—it’s dinner, with a few black olives on the side.

Easy Broccoli Two:

In a medium frying pan, add about 2 Tbsp. thinly sliced onion and 1 or 2 Tbsp. olive oil. On medium heat, cook and turn until onion is transparent to a light golden color.
Then add broccoli, cut into bite-size pieces, prepared as in Easy Broccoli One. Add 2 Tbsp. water and a dash of salt.
Mix well, and cover to steam over low heat. Stir once or twice, adding water if necessary. It’s done when it turns a bright green color or cook it to the desired tenderness. Drain excess water.
Serve with grated Romano cheese.

Wasn’t that easy? Delicious and super-healthy! Sometimes I add a few stems of ‘Happy Rich’ miniature broccoli (photo, below) if they’re ready to pick. This variety has small heads with great flavor. Several inches of the stem and the leaves are also edible. Like other brassicas, it tolerates freezing temperatures, and this one often forms heads until mid summer.

B and C vitamins are water soluble. Use as little water as possible so nutrients aren’t washed down the drain. Or, add the liquid to soup or freeze for later use.

After trying these recipes, you might decide to grow your own broccoli. Start seeds yourself or look for transplants at your local garden center or farmers’ market in mid summer to early fall and again in late winter to early spring. After you pick the main head, smaller side shoots (photo, below) will grow above the remaining leaves for many more weeks. You’d be right if you were thinking that broccoli is “the gift that keeps on giving”. Enjoy!

Time To Think About Fall Greens and Vegetables

Jul29

Ready To Sow Fall Greens and Vegetables?

Lettuce Red Lettuce Green Lettuce - PMAnguita / Pixabay

Several varieties of head lettuces.

It’s hard to believe it’s already time to start seeds for fall greens and vegetables. I’ve been putting it off because of the hot weather we’ve been having. But, unless I want to buy transplants, seeds will have to be started soon. You folks up north probably have sown seeds for the broccoli and cauliflower by now, and certainly the Brussels Sprouts.

Here in North Carolina, fall seems a long time away, but in order for us to harvest those fall greens, we need to start sowing seeds now. Remember to locate your fall/winter garden where it will receive adequate sunlight. And, of course, I’ll sow successive crops through the rest of summer and early fall, as space permits.

Because we have a long growing season in the Carolinas, we can squeeze in another crop of summer vegetables. Zucchini, summer squash, cucumber, and beans can be sown again. But with the encroaching canopy of the trees on the berm, south of the garden, I’ll be planting only cool-season vegetables. The ‘Diva’ cucumber is loaded with fruits. And I will wait patiently for every last fruit to ripen on the tomatoes and peppers.

(***Update***: A few days ago, a large and dangerously crooked pine tree was taken down, and now there’s more afternoon sun for the tomatoes and peppers. More sun also gives us opportunities to grow containerized vegetables and fall greens inside the fence, protected from deer.)

If They Can’t Take the Heat

Spinach.

Temperatures are still too hot to sow lettuce and spinach outdoors, so I’ll wait another week or two. It’s still in the 90’s! They can be started indoors, in air-conditioned space, if needed.

Check the temperature of the soil before sowing seeds in the garden. Direct sun beating down on the dark soil surface can raise the temperature too high and dry it out very quickly. Look for one of those “Easy Tunnels”, or fabricate something yourself, to partially shade the soil and the tender young seedlings. You can purchase knitted shade fabric, made from black polyethylene, from mail order suppliers. In the southern states, 30-50% shading should work during the late summer months. This could lower the temperature by 10° or 15°F. Keep the soil surface moist to ensure good germination and to cool it down.

The best germination occurs between 60° and 75°F for lettuce and spinach. I usually put transplants into the garden instead of sowing seeds directly because hungry slugs, snails, and cutworms find tiny seedlings very tender and delicious.

Organic Sluggo will bait the mollusks (slugs and snails) to their deaths, and Bacillus thuringiensis (Bt), sprayed on the seedlings, will kill cutworms. Slug baits made with iron phosphate, such as organic Sluggo, are far less harmful to pets and to people than products containing metaldehyde, so be sure to read the labels.

One way to gather up a whole lot of slugs is to place a board, maybe 1′ x 2′, over damp soil. Go out and check the underside early the next morning, old knife in hand, and cut them quickly in half or squish them any way you choose…but, don’t use salt in the garden!

Choosing Varieties of Fall Greens

Sowing seeds for fall greens and vegetables, which prefer cool weather, can be tricky in July’s heat. Look online or through seed catalogs for lettuce, spinach, broccoli, and other crops that are described as being heat tolerant varieties. Yes, all lettuce and broccoli varieties prefer cool temperatures, but some will take warmer or colder weather than others as they form heads. If you’re buying transplants, ask the grower.

Either way, plan to provide some sort of device that will lower the temperature during these last hot weeks of summer. For later harvests, I’ll sow seeds that grow cool and mature in cold weather, and they will not need the shade fabric. Plants grow better with more hours of direct sun as the temperatures cool down.

Check with your local agricultural extension office for recommendations or for a planting calendar.

Planting Young Transplants

Soil

Rich, dark soil with lighter brown clumps of clay, before incorporating.

Starting a vegetable garden with soil that has not been conditioned could result in a mediocre or poor harvest. Fall greens grow faster and larger in well-prepared soil.

Garden soil for these crops needs additional organic matter (compost, composted cow manure), drainage material (pine fines, coarse sand), and sometimes lime. A soil test will indicate the need for lime.

Our fall greens are being planted in soil that has been worked for 6 years, so it’s in very good condition. I will, however, continue to add compost, fertilizer, or manure to the garden.

When digging soil, bring some of the lower-level clay up to the surface, and turn under the richer topsoil 4″ to 6″ deep (a few inches deeper for tomatoes, in spring). Over time, the clay soil on the surface will improve as mulch decomposes or when compost is added as a top dressing. Here you can see clumps of light brown clay that were brought to the surface of the soil (photo, above) before they were broken up.

Roots

Growers use pots and market packs of various sizes, including small 9-cell packs, 4-cell packs, 2″ peat pots and 4″ plastic pots. The smaller the root ball, the more carefully you will have to monitor the care.

: Broccoli roots before…

: …and after.

An important step before planting is to rough up the outside of the root ball (photos, above). This slightly injures the inner root layer called the pericycle, stimulating the plant to quickly send out new lateral roots into the soil. Be careful not to so severely damage the root system that the plant can’t supply water to the leaves on a hot, sunny day. Do this for every plant that is about to be repotted or planted into the garden.

A root ball that’s tightly packed with roots can be shallowly scored down the sides in a few places. Use a knife, a rock, or even a twig. Or use a cultivator to pry out some of the roots.

To Bury or Not To Bury?

Broccoli ‘Arcadia’ from 4-cell-pack.

Most young vegetable transplants can be placed an inch deeper into the soil, or up to the bottom leaves. If the plant is more mature and has developed a somewhat woody or tough stem, plant it at the same level it was growing in the pot. But always, if possible, choose younger transplants.

Older plants can be stressed by being potbound or underfertilized, and might go to flower or head up prematurely, yielding undersized harvests. Young plants will require more time to grow, but they will give you the largest heads of lettuce, broccoli, cauliflower, and cabbage. If in doubt, plant the top of the root ball level with the soil surface.

Firm the soil around the roots and stem using medium pressure. Humidity in the soil between the soil particles will encourage the stem to grow fine roots without interference from tightly packed soil. Watering the plant will help the soil settle in around the root system and provide much-needed moisture.

Broccoli ‘Arcadia’ in winter.

These are same broccoli ‘Arcadia’ plants photographed in late December (photo, above). Trees on the berm cast too much shade until leaves dropped off, delaying harvest. When the garden gets more sun, heads should form in mid to late winter.

Fertilizer

Planting fall greens and vegetables into late September, I mix a handful of granular organic vegetable fertilizer into the planting area. These crops grow beautifully with adequate nitrogen, so I will soon use higher nitrogen fish emulsion. Another application of fish emulsion will be made every 2-3 weeks through November, or every 2 weeks for potted greens.

Mustard seedlings in the garden.

Microbes in the soil break down organic compounds and make nutrients available to the roots. But, as the weather cools significantly, microbial activity slows down. I’ll use synthetic soluble fertilizers a few times in winter to keep the plants growing.

Greens and vegetables will grow all winter here, with some protection during very cold weather. This is worth the effort, since I can pick beautifully fresh kale and spinach for the Sunday omelet, or a big bunch of collards for collards soup.

Mustard ‘Florida Broadleaf’ was sown in late September, and germinated a few days later. The thinned seedlings will be used in soup, salad, or an omelet. Spinach sprouted about a week later.

Arugula

: Arugula flowers.

: Arugula ‘Astro’ seedlings.

Love, love arugula! A forkful of salad greens that has a piece of arugula in it…mmm… The variety I prefer is ‘Astro’. It’s not as hot as the wild types, and it tolerates warmer temperatures. Arugula will self-sow if it likes where it’s growing. Just let it flower and set seed. The papery seed capsules release the seeds, which germinate within 2 weeks, during favorable weather, near the mother plant.

It grows well in morning sun, during warm weather, and in moist, rich soil. Those who are more adventurous than I might enjoy growing the hotter ‘Wasabi’. Arugula doesn’t look like a member of the family Brassicaceae, but it, too, is in that famous family.

You might have seen the term “cruciferous” being used when describing members of the family Brassicaceae. It refers to the flowers of these plants, which have 4 petals arranged in the shape of a crucifix. The terms brassica, cole crops, and crucifer (or cruciferous) refer to the same plants.

Broccoli

One of the most nutrient-rich foods, broccoli is a must in my garden. Nutrients include protein, Vitamins A, several B’s, C, K, minerals, fiber, and their famous phytonutrients. To say that we eat broccoli in one form or another every 2 or 3 days is not an exaggeration. Just ask Mother.

Broccoli crowns.

Heat and cold tolerance ranges from poor to excellent, depending on the cultivar. In this zone 7b area, ‘Imperial’ can be sown in July or planted as transplants from July through August; Johnny’s Selected Seeds’ catalog rates it “excellent” in heat tolerance for broccoli. Normally, broccoli grows best in cool weather, but you can extend the harvest by choosing 2 or 3 varieties that are suited to the weather at different times of the year.

The variety that will see us through the winter is cold-hardy ‘Arcadia’, which grows a large number of side shoots once the main head has been harvested. For that reason, don’t cut off too many leaves when you do harvest broccoli, because each of those leaves could be topped by another side shoot.

By the way, tender broccoli leaves are edible as well. Add them to soup, a smoothie, pasta, or a stir-fry. After the harvest is done, I keep the plants in the garden to flower. Bumble bees and other early risers are fond of this bounty, and the flowers are quite pretty!

Miniature Broccoli ‘Happy Rich’

Broccoli ‘Happy Rich’.

I’ve grown ‘Happy Rich’ for many years. This plant grows a small head at the end of a stem, harvested ideally before the white flowers open. Each of those little green beads is a flower bud, and even if the buds start opening when the stems are picked, they’re still going to the kitchen.

The head will never get to the same size as regular broccoli, but the flavor is superb. Once the little heads have been cut off with 5″ to 8″ of the stem, the plant will branch out and grow more little heads. The stem, the leaves, and the head are edible—steamed, stir-fried, or added to soup or a pasta dish.

Two plants have been growing in the garden since the spring, and they don’t look very happy. It’s been a hot summer, so I didn’t expect them to survive this long.

Bt

Cabbage worms on broccoli.

The white cabbage moths visit frequently—more frequently, alas, than I do with the bottle of Bt.

Bt is an abbreviation for Bacillus thuringiensis, a naturally-occurring bacterium that kills caterpillars of moths and butterflies (but not sawflies). Before you groan “no chemicals”, Bt is used by organic growers and it’s been around for decades. Perfectly safe, even for pollinators, and not a chemical.

All brassica crops are targeted by a few kinds of moths, which lay eggs on the leaves. They soon hatch into voraciously hungry and well-camouflaged caterpillars. After consuming some of the Bt, they stop feeding and die shortly thereafter. Young caterpillars are more easily controlled than older caterpillars. Thuricide and Dipel are two brand-name products with Bt as the active ingredient.

Yes, But Is It Sunny In the Winter?

Apr23

Before you start digging, you must first decide where the garden will be located. Many factors should be considered, and the most important one is exposure to the sun. Just outside the back door seems like the logical choice. It’s always sunny next to the patio for summer barbecues. And it’s close to the kitchen and to the water faucet.

Yes, But Is It Sunny In the Winter?

That spot is fine, if you’re interested in growing main-season vegetables. But later this year, you’d like to venture into the world of Asian greens and other cool-season vegetables. First you will need to know if it will be sunny in the winter. The garden patch gets full sun in June, but it might be entirely shaded by the house in December!

The Sun’s Path

The sun’s path across the sky, in southern NC.

The sun’s path and the shadows cast by buildings and trees vary greatly from season to season and from one latitude to another. On the shortest day of the year (the first day of winter) where I live in North Carolina, the sun rises only 31 degrees above the southern horizon. At that time, it rises and sets south of the true east-west axis. On the longest day of the year (the first day of summer), the sun is 77 degrees above the horizon, and rises and sets north of the east-west axis.

A north-facing back yard might be shaded by the house in winter due to low, slanting rays of January sun. In this case, move the proposed garden site farther away from the house. You will be able to enjoy both summer and cool-season crops. Your efforts can be divided among a few plots around the property. Plant each one with the crops that are best suited there at a particular time of the year.

Deciduous trees, such as maple, oak, and cherry, drop their leaves in autumn. Most cool-season greens will receive enough light as it filters through the stems and branches of trees. In our garden (photo, below), you can see shadows cast by twigs and branches from trees growing on the berm to the south. But, by the time the trees leaf out in spring, the sun is almost directly overhead. Tomatoes and peppers planted then will get enough sun, but as the tree canopy expands, the garden will be less sunny in the winter. Time for a bigger garden…elsewhere!

Is Your Garden Sunny In the Winter?

cool season vegetables, sunny in the winter

Cool season vegetables and greens. Plastic covers garden on very cold nights, and netting protects plants from deer.

In regions of the country with moderate winter temperatures, greens can be harvested through the season if the garden gets at least 5 hours of direct sun per day. Leafy greens (spinach, kale, mustard, tatsoi, Swiss chard, lettuce, and many others) will grow fairly well with slightly less sun than that required by head-forming vegetables, such as cabbage, broccoli, Brussels sprouts, and cauliflower.

But exposure to the sun for a longer period of time in winter is always best. The plants grow faster and stronger, and the soil absorbs more heat from the sun during the daytime. More heat prevents the soil from freezing deeply.

Using protective cold frames over the garden moderates severely cold temperatures by trapping the sun’s heat. Warmth is stored in the soil, and released to the plants during the night. Some crops, such as kale, collards, broccoli, parsley, arugula, and cilantro, tolerate cold weather. They often survive without any protection, in the southern half of the country, until they go to flower (or into the stockpot) in spring!

I’ll talk more about cold frames and other protective devices in future posts, and you might have guessed that I’m a fan. On sunny days, of course, cold frames have to be vented in order to release hot air and to get fresh air (with carbon dioxide) in.

Locate the Garden

So, once you decide which crops you want to grow—whether they’re warm-season or cool-season, or both—you can start by observing the path of the sun. Get your young math genius out there, with sticks and string, a level, a compass, and a protractor. Find how the sun and shadows track across the sky at different times of the year. Vegetable gardening could become a great family pastime!

Something else that could influence the location of the garden is the existence of underground conduit, utilities, and cables. Call your local officials (8-1-1) to have the utilities marked before digging anywhere. Tree roots also are a hassle. Guess which one wins if there are maple tree roots infiltrating the vegetable garden.
