Kale’s Delights

I’m lucky enough to have a French window of two big, inward swinging panels out of which I can look over my vegetable garden every morning. Oddly enough, the garden bed that is catching my eyes these mornings for its beauty is the bed of kale plants.
Kale plants
No, it’s not a bed of one of the so-called colorful, ornamental kales, not even a reddish kale such as Russian Red. I mostly grow just plain old Blue Curled Scotch kale, which is no more bluish than any other kale, or any other member of the whole cabbage family for that matter. What catches my eye each morning is the frilliness of the leaves and how neatly they line up along the stalk. It’s pretty.

My vision could be swayed by the fact that kale is such a healthful vegetable, being especially rich in calcium and vitamin A. Or the fact that it’s so easy to grow. I sowed the seeds in March, put out transplants in early May, have been harvesting it since the end of May, and will continue to do so probably well into December. (Another bed of kale, which I seeded right out in the ground at the end of May, is also looking good.)

Kale is unlike other members of the cabbage family. Broccoli is past its prime once buds open into flowers. Cauliflower is over the hill once the florets sidle apart from each other. Cabbage splits if left too long. Brussels sprouts needs sowing in early spring but aren’t ready for eating until touched by frost at the other end of the growing season.

Kale doesn’t have a small window of time for optimum harvest; actually, no window. It just keeps growing taller, with more leaves, still tasting good at all stages.

The only thing kale needs protection from is rabbits and woodchucks, like most vegetables, and from the various cabbage worms. One or two sprays of the biological pesticide Bacillus thurengiensis (sold under such trade names as Thuricide and Dipel) is all that’s needed for the worms, or nothing, especially in a year like this when worms were pretty much absent.

What more could I ask for from a plant: flavor, health, and beauty?

Free Kisses

I take it upon myself to personally promote the revival of an old-fashioned flower: kiss-me-over-the-garden-gate (Polygonum orientale). It’s big, it’s beautiful, and it’s distinctly old-fashioned.

If you know the weed called smartweed, you have a hint of what kiss-me-over-the-garden-gate looks like. Smartweed is a trailing weed whose flowers look like small droplets of pink dew at the ends of its stems. Kiss-me-over-the-garden-gate looks like smartweed on steroids, with “droplets” the size of bb’s. Rather than trailing, the plant rises with robust arching stems to more than seven feet high. It’s just the height and form for growing next to a garden gate, which is where my plants grow.
Kiss me over the garden gate
Kiss-me-over-the-garden-gate is a little hard to get started because the seeds germinate slowly and erratically. My plants thankfully lived up to their reputation of being self-seeding annuals, and those self-seeding plants come up more robustly than the few coddled seedlings I used to plant out each spring.

It’s self-seeding habit is sufficiently restrained for me. All I do each spring now is to weed out the few extra plants, as well as those that stray too far from the garden gate.

Ever Green Onions

For many years, in addition to starting onions from seed (sown in February!), I also went the more conventional route and bought a few “sets” for planting. Sets are those small bulbs that grow first to become scallions, which are mostly leaf, then go on to fatten into bulbs that can be harvested and stored.
Vegetable face
This year, instead of planting sets for scallions, I grew bunching onions, yet another type of onion, one that never ever makes fat bulbs. During the growing season, slender new scallions are produced around the bases of older ones. Left outdoors, they will perennialize and multiply by offsets year after year. 

I set out transplants back in early summer grown from seeds sown in spring. Even now, these scallions still look like scallions, some larger, some smaller, depending on how crowded they are to each other. No matter their size, they’ve all been flavorful right through summer and on into fall, maintaining all the time their scallion character.

SOW NOW?

Next Year’s ‘Chokes

Ahh, such a leisurely time of year to sow seeds. And for some of them, I don’t care if they don’t sprout for months. You might wonder: Why sow now; why so laid back?

I’ll start with artichoke, from whose seeds I did want to see sprouts soon. And I did. The seeds germinate readily. Right now, a few small seedlings are growing, each in its own “cell” of a seed flat, enjoying the cool, sunny weather.
Cynara, artichoke seedlings
Artichoke is a perennial whose natural life cycle is (usually) to grow leaves its first year, then edible buds its second year and for a few years hence. Especially in colder regions, artichokes can sometimes grown from seed like annuals, with a wrinkle.

To make that transition from growing only leaves to growing flower buds, the plants need to get vernalized, that is, to experience some winter cold. Except that winter cold here in the Hudson Valley (and everywhere else colder than Hardiness Zone 7) will do the plants in. So we cold-climate gardeners need to trick the plants into feeling like they experienced winter cold, just not our winters’ depth of cold.

When growing artichokes like annuals, from seed sown in spring, you make “winter” by exposing the young, growing seedlings to cool, but not frigid, temperatures (32-50°F) for a couple of weeks. The problem with this method is that the plants are fairly small when they get this signal that “winter” is over. In my experience, these small plants make commensurately small buds for harvest.

I’m lucky enough to have a greenhouse that gets very cool in winter, but not below freezing. My young artichoke plants will continue to grow very large though the very extended “autumn” weather in the greenhouse. In midwinter, they should get plenty of chilling. Come spring, after frost danger is past, I’ll plant out the large plants to, I hope, make large, fat buds.

I got this idea from growing cardoon, which is essentially the same as artichoke, except it’s grown for its large leaf stalks.
Large cardoon plant
Or it’s grown as a flower, in which case it would require the same conditions as artichoke to make flowers. I don’t like cardoon as a vegetable but do like it as a flower, so last year, around now, I sowed cardoon seeds and grew the seedlings in the greenhouse just as I’ve described for artichoke. The result was big, fat, beautiful, blue flowers. I expect the same, except I’ll harvest the artichoke buds before they open.

Actually, I grew two cardoon plants, and for some reason one of them grew only leaves all summer, and is still growing them, the olive-green leaves each rising from ground level in a four-foot-high-whorl.

More Hucks’

A couple of months ago I collected huckleberry seeds from my huckleberry plant and sowed them. As expected, they still haven’t sprouted. They weren’t expected to sprout, at least not until they were “stratified.”

Like artichoke, huckleberry (Gaylussaccia baccata) needs to feel that winter is over, in this case before its seeds will sprout. Stratification, as this cold exposure is called, prevents small seedlings from being killed by winter cold after sprouting in late summer or autumn.

My huckleberry plant in fall

My huckleberry plant in fall

Again, it’s a certain duration of cool (32-50°F) temperatures that do the trick. Under natural conditions, these chilling requirements are fulfilled in late autumn and/or in spring. In this case, colder temperatures would do no harm, but would not put any hours into the “chilling bank.” Once the “chilling bank” has been filled, the seeds await warm enough temperatures to sprout.

(For more details and wrinkles about seed germination, see my latest book, The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden.)

The pot of huckleberry seeds has been sitting outdoors, covered, since they were sown. If I want earlier sprouting, I’ll bring the pot into the greenhouse in winter. 

Ramping Up

I collected seeds from my ramp plants about a month ago with an eye to increasing my holdings. You guessed it: Ramps also need cold. But given mere stratification, the seed will not germinate. The behavior of ramp seeds is a little different from huckleberry seeds in that ramp seeds have a double dormancy.
Ramps seed heads
Roots need to grow before the shoots will sprout. That first stage requires a couple of months or so of warmth. Only after then can the second stage, shoot growth, begin, except that won’t occur until after a stratification period, with cool temperatures, again between 32-50°F. 

Under natural conditions, ripe ramp seeds get their warm period before winter sets in and then are ready to sprout in spring. But further north, where seeds ripen later, that first stage, to get root growth underway, is delayed until the summer after the seeds drop. In that case, sprouts don’t poke above ground until their second spring.

I don’t want to wait that long so I sowed my ramp seeds in a seed flat which I’m keeping in a warm place for a couple of months. After that, I’ll move the flat to cooler temperatures. And then, come spring, sprouts — I hope.

SOME THINGS FOR SOME SENSES

Visual Delight, and some Aroma

I once grew a rose, Bibi Maizoon, that I considered to be as close to perfection as any rose could be. Its blooms, that is. They were cup-shaped and filled with loosely defined row upon row of pastel pink petals, nothing like the pointed, stiff blossoms of hybrid tea roses. Completing the old-fashioned feel of Bibi Maizoon blossoms is the flowers’ strong, fruity fragrance.
Bibi Maizoon rose
(In case you don’t know who Bibi Maizoon was, she was a member of the royal family of Oman. The Bibi Maizoon rose was bred by British rose breeder David Austin.)

The bush itself was as imperfect as the blossom were perfect. Where to begin? For starters, the thin stems could hardly support the corpulent blossoms. Couldn’t, in fact, so the blossoms usually dangle upside down. Upside down blossoms were not that bad because I considered Bibi best when cut for vases indoors to better appreciate her rare appearances and fragrance.

Top those deficiencies with the fact that Bibi Maizoon was also only borderline cold hardy in my garden and you would rightly guess that I no longer grow this rose.

I haven’t abandoned David Austin roses. I generally like them for their old-fashioned look: the bushes are, well, bushy and full; the blossoms have softer colors than those of traffic-stopping hybrid tea roses; and they are disease resistan and strong-growing.

I’ve previously praised the variety L. D. Braithwaite for its almost nonstop, dark red blossoms, red tinted leaves, and ability to laugh off any amount of cold. Three other varieties — Golden Celebration, Lady of Shallot, and Dame Judi Dench — came into my garden in the last year, their blossoms with varying degrees of yellow, the first a pure golden yellow, the second apricot-yellow, and the third apricot orange. Delicious. They all seem, so far, near-perfect.

Organoleptic Delight, and also Beautiful

Ellison’s Orange is as unknown to most people as is Bibi Maizoon. It’s an apple, an old and very delicious apple, and, oddly enough, ripening right now. Everywhere else I read that this apple is supposed to ripen later in September and on into October, yet every year my Ellison’s Orange fruits ripen about this time of year.

Like Bibi Maizoon, Ellison’s Orange has its good and bad sides. On the plus side, it bears very well and at a young age. It also seems to be somewhat resistant to scab and cedar apple rust diseases, contradicting other sources on this point also. And what a beauty the fruit is, with its orange blush over a yellow background.

For me, the downside of this variety is the absolute necessity to pick it at just the right moment. One day an apple seems puckery underripe; the next day it might be sleepy and soft. If I harvest very carefully, I catch an apple at its delectable best, which is sprightly with an intense flavor that hints of anise seed.
Ellison's Orange apple
I made my tree from a piece of stem whose cells trace back over a hundred years, to the garden of a Reverend Ellison in Lincolnshire in the east of England. The parents of the reverend’s new apple weren’t lightweights. One parent, Cox’s Orange Pippin, the king of British apples, has an intense flavor that sometimes hints of anise seed. The other parent, Calville Blanc, an old French apple popular in the court of King Louis XIII, has a spicy flavor with just a hint of banana. No wonder Ellison’s Orange tastes so good – as long as I catch it at the right moment.

Another Tasty Delight

If you buy corn at a farmstand or market these days, no need to have boiling water ready, as gardeners did in the past to stop enzymes from starting the conversion of kernels from sugary sweet to starchy bland. Two genes incorporated into modern corn varieties dramatically slow this flavor decline. They also ratchet up the sugars, making modern corns supersweet to begin with.

Call me old-fashioned, but my favorite variety of sweet corn, the only variety that I grow, is the old variety Golden Bantam, which lacks those modern corn genes. Although not nearly as sweet as modern hybrids, Golden Bantam has a very rich corny flavor with – to some tastes — just the right amount of sweetness.

Golden Bantam, a hit since 1906

Golden Bantam, a hit since 1906

Golden Bantam was introduced into the seed trade in 1902 by W. Atlee Burpee Company, who got their original 2 quarts of seed from New York farmer William Coy, who had tasted and enjoyed eating some ears at his cousin’s house in Massachusetts. Long story short: Everyone fell in love with Golden Bantam and it became the most popular corn of its day. An article in The Boston Transcript of 1926 states that “In the twenty-four years since [1902] it has made more friends than anyone else could make outside the movies. Which proves that popularity does sometimes follow real merit.” It’s an odd way to compliment but you get the picture.

Golden Bantam pre-dates hybrid varieties, the latter of which, in addition to other characteristics, ripen very uniformly. In a backyard garden, a whole bed of corn ripening at once isn’t necessarily a plus. I want to eat some corn every day, with a little extra each day for freezing.
Corn hills
My four beds of corn, the first planted in mid-May (around the date of our last-killing frost of spring)  and the subsequent beds staggered every two weeks, provides just that. We’ve eaten corn almost every day since each mid-August and Golden Bantam shows no signs of slowing down or boring us.

Genetics, Timely Harvest, and ?

As I led my nephew Jeff, his wife, and their two kids around the garden a couple of days ago, I plucked fruits and vegetables here and there for them to sample. They could compare them with what New York City, where they live, has to offer. They were blown away by the flavors here.
Delectable fruits & vegetables
Okay, I cheated a little. They got to sample some of the best of the best: figs so soft they were drooping from their stems, white alpine strawberries, Sungold cherry tomatoes, Golden Bantam sweet corn, and Kentucky Wonder green beans, all picked on the spot and at their peak of perfection. The Golden Bantam corn, you won’t find that offered for sale pretty much anywhere these days although it was the standard of excellence in sweet corn 100 years ago. The white alpine strawberries (Pineapple Crush) are too small and too soft for anyone to market commercially.

But genetics isn’t the whole story. Timely harvest is as important. Commercial considerations aside, it takes a certain skill to know just the right moment to do the deed.

With some plants, especially vegetables, timely harvest is easy. You pick such vegetables as lettuce, beans, and okra as soon as they’re big enough to suit you. You pick tomatoes when they’re red, which is also when I pick sweet peppers; red peppers taste quite different and, to me, a lot better than green peppers.

I haven’t grown eggplants that much over the years. This year they are particularly abundant and I’m still learning how to pick them. Full size? Glossy?

Sweet corn can also be tricky. It took me a few years to get the knack of picking it at its best. I first look for dried up silks and then, taking a tip the vegetable extension specialist at the University of Wisconsin passed on to me many years ago, I wrap my fingers around the ear and feel for fullness. That’s when it’s time to snap the ear down and off the stalk. Gauging that fulness does take practice.

Test for Ripeness

Fruits are a little trickier than vegetables, especially some fruits. Easiest of all are raspberries and blackberries. Tickle the clusters and let the truly ripe ones drop off, as they are wont to do, into the palm of your hand. Too many people tug at blackberries to get them off the plants; flavor suffers. Blueberries are similar to blackberries in that color doesn’t tell of full ripeness; the tickling method does.
Black raspberry fruit
I grow a number of varieties of two vining fruits: grapes, of course, and hardy kiwifruits. The kiwifruits, which will begin ripening in a couple of weeks, retain their fresh, green color right through ripeness. What they do do when ripe is to soften. But not all together. Fortunately, when sufficiently mature on the plant, these fruits can finish ripening after harvest. As soon as the first kiwis ripen, I pick them all. They ripen to perfection in a few days at room temperature, longer under refrigeration.
Hardy kiwifruit
Blue or red grapes seem ripe when they turn their final color. Ripe for commercial purposes perhaps, but not perfectly so. When truly ripe the whole bunch will snap easily from the cane to which it is attached. I sometimes leave the bunches (the ones I enclosed in paper bags in early summer) even longer and, to a point, their flavor just gets better and better.
Edelweiss grape
Most fruits, in fact, taste best if harvested when ready to part with the plant. That’s why for fresh eating, not storage, I sometimes harvest my apples from the ground, daily, the morning they drop. This might not be the best method for all varieties but makes for the very best Macoun apples.
Hudson Golden Gem apple
Generally, with tree fruits, I look for a change in color, especially background color, before considering harvesting a fruit. If there’s any green, I let it be. If color tells me that a fruit is potentially ready to be picked, I cup the fruit in hand, then lift and twist. If ripe, the fruit stalk readily separates from the plant. If that doesn’t happen, the fruit needs more time on the plant.

Tricky, for Me at Least

Two fruits whose harvest moment I’m still honing are watermelon and European pears.

I’ve tried all the methods with watermelon: thumping for a sound not too hollow and not to dull (the sound of knocking your knuckles against your chest as opposed to your forehead or stomach); a dried tendril opposite the fruit; a yellow-bellied fruit. They’re all guides but none are the end-all to timely harvest. I never had that problem with my large watermelon crop from my garden in southern Delaware.

Magness pear

Magness pear

European pears ripen from the inside out so become mush if left on the plant to thoroughly ripen. They need to be harvested mature but not yet ripe as indicated by some fruits dropping, a slight change in skin color, and readiness of the fruit stem to part from the branch. Fruits brought indoors to finish ripening are ready to eat when the flesh at the stem end gives with slight finger pressure.

Still, it takes a certain je ne sais quoi. And again, I’m adept at timely harvest of those varieties I’ve grown the longest and of which I have the most.

Climacterics

One reason pears and kiwifruits can ripen to perfection after harvest is because they are climacteric fruits, which undergo a burst of respiration and ethylene (a plant hormone) production as ripening begins. Some of these fruits, which also which include banana, apple, tomato, and avocado can, if sufficiently mature, ripen following harvest. Soon after their climacteric peak, these fruits start their decline.

Citrus, fig, strawberry, plum, and raspberry are examples of non-climacteric fruits, whose ripening proceeds more calmly. Non-climacteric fruits will not ripen at all after they’ve been harvested. They might soften and sweeten as complex carbohydrates break down into simple sugars, but such changes are indicative of incipient rot rather than ripening or flavor enhancement.

For more about flavor, ripening, and climacteric, see my latest book The Ever Curious Gardener: Using a Little Natural Science for a Much Better Garden.

Pests Pesky and Not So

Memories

The tumbled over Red Russian kale seedling brought back old memories. It was like seeing the work of an old friend — or, rather, an old enemy. It’s been so long since I’ve seen a cutworm at work in my garden that I couldn’t even get angry at it.

Cutworm and friend's broccoli

Cutworm and friend’s broccoli

I scratched around at the base of the plant to try and find the bugger. Too late, fortunately for him or her because its fate would then have been a two-finger crush. The cutworm in a friend’s garden I visited last spring was not so lucky.

The bad thing about cutworms are that they chop down young, tender seedlings. At that age, seedlings’ roots lack the energy to grow new leaves; the plants die. (I wonder how the cutworm benefits from lopping back the seedling; the felled plant usually doesn’t get eaten.)

Cutworm damage

My kale plant

The good thing about cutworms is that, in my experience, they are few and far between — just one or two every few years.

Also, on a garden scale, they’re easy to control, if needed. They prepare for their meal by wrapping their bodies around the plant stems. When I feared them more, I would cut cardboard rolls at the center of paper towels or toilet tissue into lengths of about 1-1/2 inches long, slit one site, fit it around the seedling, press it into the ground, and tape it back closed. A bit tedious, I must admit.

Then I read that cutworms can be fooled. They only attack soft, young seedlings. A thin stick or toothpick slid partway into the ground next to a seedling makes a cutworm think the plant is a woody plant and, hence, out of its league. Since I didn’t find the culprit in my garden, I slid thin sticks next to nearby seedlings. For my friend’s garden, I returned from her kitchen with a handful of toothpicks and instructed her teenage son what to do with them.
Cutworm protection with stick
Except for today, I haven’t taken precautionary measures against cutworms for many years. Especially every morning, robins, catbirds, and mourning doves are pecking around the ground in my garden; I suspect that’s one explanation for the lack of cutworms.

A Good Parasite

A week or so ago, I saw another old “friend” in the vegetable garden. I noticed that leaflets had been thoroughly stripped from one region of one tomato plant. Obviously, a tomato hornworm, a voracious and rapid diner, was lurking somewhere amongst the existing foliage. A cause for panic? No!

The culprit, a green, velvety caterpillar with widely spaced, thin white stripes and some rows of black dots, is undoubtedly intimidating.
Tomato hornworm
Besides its voracious appetite — you can hear it chomping away — it is the size of an adult pinky.

Still, not to worry. Like cutworms, tomato hornworms turn up in my garden only every few years. And again, like hornworms, they seem to arrive, or show evidence, solo.

I did not reach out to crush the hornworm when I saw her because her back was riddled with what looked like grains of white rice standing on end. Those “rice kernels” are actually the eggs of a parasite that in short order turns that beautiful body to an ugly mush. It’s a dog eat dog world out there.
Parasitized hornworm

A Call for Action with This One

I can’t be so complacent about all pests that can turn up in my vegetable garden. Probably the worst one that causes problems every year is one or more of the caterpillars now, as I write, chewing away on the leaves of cabbage and its kin. The symptoms are quite evident: holy . . .  whoops, holey . . . leaves upon which is deposited dark green caterpillar poop.
Cabbageworm damageA close eye is needed on cabbage and its kin because one day there’ll be no damage and next time you look, leaves are riddled with holes and poop.

And then, action is necessary. Hand-picking is one option. I choose to use the biological insecticide B.t., short for Bacillus thurengiensis and commonly sold under such names a Dipel or Thuricide. It should be used with restraint because the insects can — and, in some cases, have — developed resistance to this useful pesticide which is very specific in what it harms and what it leaves alone.

Now that I mention it, excuse me for 10 minutes while I mix up a batch of spray for my cabbages, Brussels sprouts, and kale plants . . .

I’m back. The caterpillars seem to prefer cabbage, Brussels sprouts, and cauliflower over kale, which is fine with me because kale is my favorite of the lot.

Many predators, including certain wasps and beetles, diseases, birds, and bats, keep these caterpillar pests under control. Evidently not enough, though, in my garden.

Seeds Want to Grow

/7 Comments/in , , /by

Yes, They Want To, But . . . 

Today, as I was carefully planting a bed with turnip, arugula, and mustard seeds, I got to thinking how easy it is to grow plants from seeds. It’s not surprising. After all, seed plants evolved millions of years ago and over the years have further evolved to germinate and grow under varied conditions. This would be especially true of those plants we call weeds.
Cynara, cardoon, in bud

So, with all that evolution backing me up, why the great care in planting those seeds today? Seeds do want to grow, but extra care increases the chances for success. The threats to germination and growth are competition from weeds, temperatures that are too warm or not warm enough, old seed, and insufficient soil fertility, air, or moisture. That’s not all, of course; there’s too many salts in a soil (and not just NaCl “salt”), seed-eating animals, and infections from pathogenic fungi. 

Whew! That list makes growing from seed seems fraught with roadblocks. But it’s not.

Steps to Improved Germination and Growth

My extra care in planting began back last autumn when I spread an inch depth of compost on top of the bed right after clearing it of garden plants and weeds. That compost provides nutrients, beneficial microbes, and increases aeration and water retention.

Earlier this season, the bed had been home to bush beans. Bean roots, left in the soil to rot, will provide further fertility — mostly nitrogen — for today’s planting.

The bean plants, and a few weeds, were cleared from the bed a couple of weeks ago, still too early for today’s planting of fall crops. While the ground was waiting, I covered it with a black tarp. The tarp, an old billboard sign (from www.billboardtarps.com and reusable for years) that is black on its back side, stimulated growth of ever present weed seeds in the soil. The seeds germinated, then died from lack of light beneath the tarp.

After year upon year of compost applications, the soil has very good tilth, so all it needed, once I removed the tarp, was a light raking to present a loose seedbed. Into it, with a trowel, I carved the first furrow the length of the bed. 

Depth of planting is important. An oft-repeated rule of thumb is that the depth to sow seeds is twice their thickness. Not true! Correct planting depth needs to also take into account the looseness of the soil; looser soil, more depth. And anyway, the seeds that I planted are only about 1/32” in diameter, making it well nigh impossible to make a furrow 1/16” deep. In my loose soil, that depth would dry out too quickly. I went with the less precise “sow shallowly.”
Radish seedlings

Garden plants grown from seed can suffer from competition not only from weeds, but also from each other. True, the young seedlings could be thinned out if too crowded after germination. With seed less than two years old and care in planting, I was confident about germination, so sowed the seed thinly.

After sowing the seeds and covering them came the all-important firming of the soil. The removal of the bean plants and the pre-plant raking to smooth the surface left plenty of large pores, through which water would run right through. 

Tamping down the soil with a garden rake over the covered furrow tightened up the pores so that they can hold capillary water. Remember high school chemistry class (or was it biology class) when water was shown to be drawn up into a capillary tube against the force of gravity? Firming the soil keeps moisture around the newly sown seeds; plus, water can be drawn upwards or sideways to that area. Weed seeds, sitting in still loose soil beyond the tamped area, won’t have such an easy time of it.

Finally, I watered — thoroughly enough for the water to penetrate but, to avoid washing away the seeds, not too fast. My vegetable garden has drip irrigation; I moved the drip line up right next to where the furrow was. Frequent watering is needed until seeds germinate and their new roots reach the wetting from down in the soil. An electronic moisture probe can indicate how deep moisture lies beneath the surface.

And Now for a Flower, or Is It a Vegetable?

Many years ago I grew cardoon, a vegetable whose 3-foot-high stalks are something like celery on steroids. Cardoon stalks growing in gardenThe flavor hints of artichoke, a close relative. None the less, for me the flavor was awful and the stalks were tough. (Cardoon is usually covered to blanche them a few weeks before harvest. Blanching did not make mine more edible.)

Yet I am now enamored with this plant — not for eating but for its thistle-like flower. Cardoon is a perennial that begins to bloom in its second year, after experiencing a period of cool temperatures in winter. Cool, not frigid; cardoon is not cold hardy here in the Hudson Valley.

Last summer I planted seed and grew the plant in pots. Those pots spent the winter in my greenhouse, where temperatures never dipping below 35° F. reminded them of their Mediterranean origin. Once warm weather settled in this spring, I planted them out in my flower garden.Cardoon in flower

The bud on one plant that has been slowly unfurling is well worth the care I put into the plants.

Of Corn and Compost

/7 Comments/in , /by

Bed Transformation

In an hour and a half this morning, a 20’ long by 3’ wide bed of spired, aging corn stalks morphed into a bed of succulent, young greenery in the form of endive and Chinese cabbage transplants.

Before beginning this job I harvested what ears were still ripe on the stalks. The yield from this first corn planting was small, both in quantity and size of ears. Old fashioned Golden Bantam, as told by its name, normally yields small ears — but not usually as small as the 3 to 5 inch long ears I harvested. Golden Bantam sweet corn, non-hybrid
Planting in “hills” (clusters of 4 plants) usually provides for adequate pollination, but poor weather at a critical developmental stage might have thrown pollination awry.

At any rate, with ears harvested, I lopped each stalk in half with my Hori-Hori knife, then dug straight down right around the base of each hill to sever the main roots so I could jerk the cluster of stalks up out of the ground. I also cleared away from the bed any weeds, and then carted everything over to a compost pile.

For the return trip from the compost pile, I loaded the cart with finished compost from another pile. An inch depth of compost slathered on top of the old corn bed had it ready to receive the endive and Chinese cabbage transplants I had waiting in the wings. The 40 transplants had grown up during the month of July in a seedling flat and were just ready to outgrow their individual cells. Each went into a quickly made hole jabbed into the ground, the holes 15” apart in each of the two rows running down that bed.

The refurbished bed will provide good eating beginning in early October and, with some covering for protection, on into December.

Compost Discoveries

Besides merely compost, the compost pile often yields some interesting and forgotten objects. (Some annoying things as well, such as those fruit labels glued to the skin of almost every piece of commercial fruit.)

For years now I’ve had trouble bringing myself to tossing anything compostable into the garbage for eventual burial in a landfill. It seems so wasteful of materials and disrespectful to the soil to use it as a dumping ground for cast-offs. Soil is a limited resource so eventually there will be no more acreage to bury trash.

Much of my clothing is cotton, wool, or leather — natural products that would eventually decompose to enrich a finished compost. So I sometimes compost such garments, forgetting that I did so until an uncomposted piece of the garment makes an appearance as I turn the compost pile or shovel out the finished material.

Partially composted Levi jeans

Partially composted Levi jeans

The distinctive zipper and fly snap from my Levi jeans, for example. After three compost cycles, except for the zipper and fly snap, those jeans are surprisingly intact but look more like sheer polyester slacks than Levi’s jeans. In contrast, my daughter’s non-Levi jeans were threadbare after merely one cycle.

Composted (almost) non-Levi jeans

I came upon a not immediately identifiable object today as I shoveled out finished compost for spreading on the endive/Chinese cabbage bed. It was about a half inch thick, almost flat except for some bends, and spongy. What could it be? Aha! The cushioning from my sheep skin booties. Most of the leather portion had decomposed.

My guess is that the bootie was transformed as far as it would go in the near future so I’m not returning it to the new pile for another cycle.

Worms in My Ears (Some of Them)

My ears, now, are relatively large. Corn ears, that is.

Since writing about the diminutive ears from my first planting of sweet corn, I’ve harvested a few ears from my second planting. That second planting went in 2 weeks after the first planting but is ripening close on its heels. Warmer weather earlier in the season compressed those ripening dates.

Just about every ear in this second batch of ears is large (for the variety Golden Bantam) and well filled with kernels. I occasionally find a corn earworm feasting on some of the kernels at the tip of the ear. Corn earworm
That’s the nice thing about home-grown sweet corn — it’s not nice having the earworms but it is nice not being bothered by them. Corn farmers don’t have that luxury. I just break off the tip with the worm and enjoy the rest of the ear.

The earworms got inside the husks by eating their way down the corn silks. Spraying the corn with the benign biological pesticide Bacillus thurengiensis (sold under such friendlier names as Thuricide), or cutting off or squirting some of mineral oil into the silks right after pollination is complete (3 to 7 days after silks appear) could control this pest. But why bother for an occasional pest that is so easily ignored or removed?

Maintenance, Pruning

For many gardeners, spring is the critical gardening season, what with preparing the soil, starting seedlings, setting out transplants, pruning, watching and staying prepared for late frosts and . . .  In my view, right now is just as crucial, and for an equal number of reasons.

True, a 90 degree day with high humidity doesn’t exactly pull you out to the garden to putter around in blazing sunlight. But early mornings around here are mostly cool, calm, and beautiful.

Much of what needs to be done is regular maintenance. Pruning tomatoes, for instance.Tomatoes, staked, July I train my tomato plants to stakes and single stems, which allows me to set plants only 18 inches apart and harvest lots of fruit by utilizing the third dimension: up. At least weekly, I snap (if early morning, when shoots are turgid) or prune (later in the day, when shoots are flaccid) off all suckers and tie the main stems to their metal conduit supports.

Espalier is the training of trees to two dimensions whereby the tracery of the stems is as decorative a plant feature as are the leaves, flowers, and/or fruits. To maintain that tracery of branches, my espaliered Asian pears need frequent pruning. Espalier Asian pearI lop wayward shoots either right back to their origin or, in hope of their forming “spurs” on which will hang future fruits, back to the whorl of leaves near the bases of the shoots.

The response of the pear trees depends on the weather, which is unpredictable. Dry sunny weather is conducive to spurs. Rainy weather coaxes, instead, new shoots pop out right where I cut back old shoots. I think.

Maintenance, Water

Whether or not the weather is dry, rampant growing plants quickly suck the soil dry. So I also keep attentive to watering this time of year. The vegetable garden and potted plants are the neediest in this respect; fortunately, they demand little from me to do because a timer turns its drip irrigation system on and off automatically. All I have to do is to periodically check to make sure drippers are all dripping. Drip tubes to potted plantsNewly planted trees and shrubs are another story. This first year, while their roots are spreading out in the ground, is critical for them. I make a list of these plants each spring and then water them weekly by hand all summer long unless the skies do the job for me (as measured in a rain gauge because what seems like a heavy rainfall often has dropped surprisingly little water).

A one-inch depth of water is needed to wet a soil about a half a foot deep. I provide this with 3/4 gallon of water per estimated square foot spread of the roots.

Fall preps

Sowing seeds and setting out transplants isn’t only a spring gardening activity. Tomatoes, peppers, eggplants, cucumbers, and other summer vegetables peter out during the shorter, cooler days of late summer and early fall. But there are plenty of vegetables that enjoy growing conditions that time of year.

Some of the fall vegetables need to be sown now to be large enough to mature in fall. No need to provide space for them by digging out tomatoes, peppers, or any other summer vegetables. I sow endive, kale, lettuce, Chinese cabbage, and, if I could stomach it, cauliflower seeds in midsummer in seed flats. Once they sprout I “prick them out” into individual cells of automatic watering GrowEase trays for later transplanting. Autumn seedlingsNot only vegetables get this treatment. Buy a packet of seeds of delphinium, pinks, or some other perennial, sow them now, overwinter them in a cool place with good light, or a cold (but not too cold) place with very little light, and the result is enough plants for a sweeping field of blue or pink next year. Sown in the spring, they won’t bloom until their second season even though they’ll need lots of space that whole first season.

Cuttings are another way to propagate plants this time of year. Early this morning, when cells were plump with water, I made cuttings of hardy kiwifruit and begonia.

And, Yes, Weeds

Weeds can make all this pruning, watering, and seeding for naught. Clear ground is needed in which to eventually set my cabbage and kale transplants. Weeds stealing water and nutrients, even sunlight, won’t let plants grow at their best. They’ll also promote disease by preventing free flow of air; fungi fester under damp conditions. Weedless corn & lettuce bedEvery time I look at a weed, I’m thinking how it’s either sending roots further afield underground or is flowering (or will flower) to scatter its seed. Much of gardening isn’t about the here and now, so I also weed now for less weeds next season. It’s worth it.

Somethings Old, Somethings New, Nothing Blue

Rare and/or Perennial

I usually draw a blank when someone asks me “So what’s new in your garden for this year?” Now, with the pressure off and nobody asking, I’m able to tell.

Of course, I often try new varieties of run of the mill vegetables and fruits. More interesting perhaps, would be something like the Noir de Pardailhan turnip. Turnip Noir de PardailhanThis ancient variety, elongated and with a black skin, has been grown almost exclusively near the Pardailhan region of France. Why am I growing it? The flavor is allegedly sweeter than most turnips, reminiscent of hazelnut or chestnut.

I planted Noir de Pardailhan this spring but was unimpressed with the flavor. Those mountains near Pardailhan are said to provide the terroir needed to bring out the best in this variety. (Eye roll by me. Why? See last chapter in my book The Ever Curious Gardener for the skinny on terroir.) I’ll give Noir de Pardailhan another chance with a late summer planting.

Also interesting is Nebur Der sorghum. This seeds of this variety, from South Sudan, are for popping, for boiling, and for roasting. What sorghum has going for it is that it’s a tough plant, very drought resistant and cosmopolitan about its soil. With my previous attempt with sorghum, with a different variety, the seed didn’t have time to ripen. Nate Kleinman, of the Experimental Farm Network, where I got Nebur Der seed, believes this variety may ripen this far north.

Nate also suggested some perennial vegetables to try — that’s right, vegetables you plant just once and then harvest year after year. I planted Caucasian mountain spinach (Hablitzia tamnoides), a relative of true spinach, and, as predicted, growth is slow this, its first, year. Hablitzia, Caucasian mountain spinachNext year I can expect a vine growing 6 to 9 feet high and which is both decorative and tolerates some shade. What’s not to like? (I’ll report back with the flavor.)

Andy’s Green Multiplier Onion (Allium cepa var. aggregatum), also from the Experimental Farm Network, will, I hope, fill that early spring gap here when some onion flavor can liven salads. Multiplier onionLater in the season, cluster of bulbs form, similar to shallots, although forming larger bulbs. They can overwinter and make new onion greens and bulbs the following years.

And finally, again from Nate, the New Zealand strain of perennial multiplying leek (Allium ampeloprasum). This seems to be a variable species, with some members yielding large bulbs know as elephant garlic. The flavor might vary from that of leek to that of garlic.

One more perennial plant (this one for the greenhouse so not really perennial here), is jicama (Pachyrhizus erosus), a climbing vine in the pea family. The flavor and texture of the large, turnip-shaped root is something like water chestnut. The flavor of the other parts of the plant are . . .  not to be tried. All other parts are poisonous! The greenhouse is so hot in summer that I figured this is one of the few plants, besides figs and ginger, that would thrive there.

Probably not. I should have researched before planting: Jicama roots are poor quality unless the plant experiences a long period of warmth with short days. But when short days come around, my greenhouse is starting to fill with lettuce, mâche, spinach, and other fresh greenery for winter salads.

Could Be Frightening, But Not

At least one more newish crop made it into my garden this year, one that I hope is not perennial. The plant is sometimes called yellow nutsedge, sometimes chufa, and sometimes tiger nut or earth almond. When I lived in southern Delaware, “yellow nutsedge “would strike terror in the hearts of local farmers; it’s been billed as “one of the world’s worst weeds.”

But there are two botanical varieties of yellow nutsedge. That weedy one is Cyperus esculentus var. esculentus. The one that I am growing is C. esculentus var. sativus. The latter is not weedy; it rarely flowers or sets seed, and doesn’t live through the winter. Both varieties, being sedges, enjoy soils that are wet but also enjoy those that are well-drained.Chufa plants growing

The edible part of chufa are the dime-sized tubers, which are sweet and have flavor likened to almonds. I did grow the plant once and thought the tubers tasted more like coconut. Chufa tubersThe problem was separating the small tubers from soil and small stones. I have a plan this time around — more about this at harvest time.

I’ll be in good company growing chufa. We humans munched on them in the Paleolithic period and they were good food to the ancient Egyptians. Hieroglyphic instructions detail the preparation of chufa for eating, as a sweet, for instance, ground and mixed with honey.

Even today, chufa is enjoyed in various parts of the world. The chufa harvest is anxiously awaited each year in Spain, when the dried tubers are washed and pulverized, then made into a sugar-sweetened “milk” know as “Horchata De Chufas.”

TIME TRAVEL

18th Century, Here I Come!

Is that me playing the fife? No.

I just returned from time travel one month forward and a couple hundred years backward. Both at the same time! I did this with a trip to Colonial Williamsburg, Virginia, where black locust trees were in full bloom, which is about a month ahead of when they will be blooming up here in New York’s Hudson Valley.

The impetus for this time travel was Colonial Williamsburg’s Annual Garden Symposium, at which I was one of the presenters. (I did presentations on espalier fruit plants and on growing fruits in small gardens.)

Williamsburg is a magical place anytime of year, and especially so, for me, in spring. (I first fell in love with the place on a family trip when I was 7 years old; on subsequent visits, I’ve forgone the three-cornered hat I wore on that first trip.)

The governor's garden

The governor’s garden

The Symposium included tours through many of the colonial gardens, where we  could see, in action, “colonial” gardeners caring for their plants — in many cases using some of the same techniques we use today. Glass cloches, for instance, covered portions of some gardens to hasten warming of the soil for earlier sprouting of seeds. Colonial vegetable gardeners at workFlowering meads of herbs, flowers, and grasses blanketed the ground beneath most of the orchards, providing — probably unknown back in colonial days — forage for beneficial insects to help protect crop plants.

The flowers and vegetables — and fruits in the orchards — are the kinds and varieties grown in colonial times: cardoon, cornflower, chives, cockscomb, pot marigold, nasturtium, hollyhock, Johnny-jump-up, Tennis Ball lettuce, Yellow Crookneck squash, chard, and, of course, corn. Field corn, probably, but also, possibly, sweet corn, which was first given by the Iroquois to settlers in the late 18th century.

The gardens in Williamsburg provided and provide more than just sustenance. As in the orchards, flowers mingle with crop plants, in this case, vegetables. Most yards in the reconstructed town are one-half acre, with the land separated into sections with white wood fencing. The whole effect is très charmante. Couple that look with the lack of automobiles within the reconstructed town, and the quiet nights illuminated by the soft glow of fire and candle light (supplemented by electric lights with a candle-like glow), and I think I may want to move back into the 18th century.

Wall Envy

One problem I had with Colonial Williamsburg was wall envy. The church on Duke of Gloucester street, the governor’s mansion, and some other public spaces were enclosed by beautiful brick walls capped with functional and decorative rounded brick.

Most of the homes were covered with white-painted, wooden clapboards. The church and the governor’s mansion were made of brick, which, obviously, harmonized well with their brick walls. Brick wallsMy own home is brick; even a few four-foot-high walls around my vegetable garden and in other areas would improve the general appearance — and provide, warmer microclimates for cold-tender plants or early harvests. Not that the rustic locust fencing and arbors enclosing my vegetable garden look unsightly . . . but I’d like some brick walls.

Incidentally, bricks are made on site at one of the many trades demonstrated within the reconstructed town. I stopped in at the gun shop and stayed soaking up history I never learned in school — how most colonists owned relatively inaccurate muskets which were good enough for hunting and keeping varmints out of gardens, and the real sharpshooters were those with “long rifles,” that is, firearms with rifled barrels that spun their lead shot. But winning a battle wasn’t all about sharpshooters. Long rifles took much longer to reload than muskets, and which side threw the most lead in the air often was what decided who won.

(As part of my immersing myself in 18th century life, I signed up to go to a shooting range to actually fire a flintlock musket. This event, as recorded with 21st century technology, a phone, is documented Musket shooting1, Williamsburg, Musket shooting2, Williamsburg.)

Bricks, rifles, furniture: all these trades are practiced as they would have been in the 18th century. The rifle maker begins his work with nothing more than a block of wood and a block of iron. Four-hundred  hours later, he has in hand a finished rifle. Fabric artisans begin with a sheep or flax seeds and some natural dyes. Cabinetmakers begin with trees or rough cut wood. Their tools are the same as those that to which their 18th century forebears had access.

Plant Envy

In addition to my wall envy, I also experienced the usual plant envy that afflicts me when I go south. Southern magnolia tree reach majestic proportions in Williamsburg; I would like to, but cannot, grow them in this cold climate. Crape myrtle is another, for its flowers and its bark mottled in pastel shades; too cold here for this one also.

I did come upon a number of specimens of fringe tree (Chionanthus spp.), with which I’m only vaguely familiar. The fringes of white blossoms dangling in profusion from the branches made me want to become more familiar, i.e. to plant, this shrubby tree. It turns out that I could — and will — grow fringe tree.Sheep and a barn
