PERENNIAL VEGETABLES

Hablitzia: What a Name!

At last night’s appropriately social distanced “zoom” dinner with my daughter, she commented on how tasty my salad looked. “All home grown,” I replied, and held up to the computer screen a leaf of one of the major contributors to my bowl of greenery, Caucasian mountain spinach (Hablitzia tamnoides). “Looks like some leaf you just plucked off a tree,” says she. Yes, it did, but it was as tasty and as tender as any leaf of regular garden spinach.
 Caucasian mountain spinatch
It’s with good reason that the two “spinaches” are so similar: They’re both in the same family, Amaranthacea, also kin to beets, chard, quinoa, lamb’s quarters, and pigweed.

Caucasian mountain spinach has it over conventional garden spinach in a number of ways, most significantly its being a perennial. I planted it last spring and don’t plan on doing so ever again. Not that making new plants would be difficult. They were easy from seed, and cuttings are also said to root easily. The quickest way to have larger new plants would be to divide the clump sometime after the tops have died back for winter or before new sprouts appear.

Being a perennial, Caucasian mountain spinach won’t lose quality as it goes to seed during the warmer, longer days of late spring and summer. White flowers, with a faint aroma of cilantro, appear in June and July, but the leaves still make tasty additions to salads or cooked dishes.

Right now, plants are starting to stretch their leafy stems skyward. Making use of the third dimension in gardening — up — makes for efficient use of garden space, a plus for any plant in an intensive garden. They’d like something on which to climb, which they do by pulling themselves upward in the same way as do clematis vines, twisting their leaf stalks around whatever they can. I’ll be providing a ladder for them made from posts and chicken wire.

Now that I think of it, Caucasian mountain spinach also makes use of the fourth dimension in gardening — time — since it can make its way into the kitchen from when my plum trees bloom until I harvest the last of my apples.

The Good King, and Others

The bed that’s home to Caucasian mountain spinach is also home to another perennial bit of edible greenery, Good King Henry (Blitum bonus-henricus), also sharing the Amaranthacea family. That bed gets some shade in the afternoon, which is all to the liking of Caucasian mountain spinach, not so much to Good King Henry.
Good King Henry
No matter, because Good King Henry is not, in my opinion, nearly as tasty as its Caucasian cousin. The King’s leaves are good cooked, but not great, and not very good raw in salads. One reason I like it so much is for its name, both the common name and the botanical name.

I had hoped the bed would also be home to the perennial leek and perennial onion (Welsh onion) that I sowed and grew last season. But there’s not a sign of either plant this season. I guess they’re not all that perennial, odd since last winter was downright tropical (for here), the thermometer hardly dipping below zero degrees Fahrenheit.

If I wanted early onions, as greens, some kinds are reliably hardy. An interesting one that I grew decades ago is Egyptian Onion, also known as Walking Onion. They “walk” because the cluster of small bulbs atop the green stalks weight the stalks down till they eventually bow to the ground, depositing the cluster a few inches from the plant. Egyptian onionThe bulbs take root, grow, bow, and deposit the bulbs another few inches away, so, unfettered, the plant spreads by “walking” around the garden. I stopped growing it because the flavor was too sharp for me.

One More, This One Well-Known

One more perennial vegetable, this one familiar to everyone, is asparagus. I don’t understand why anyone who has a garden doesn’t grow asparagus. Even a flower garden, to which asparagus can offer a soft, green ferny backdrop. A bed offers two months of almost daily harvest. Rabbits and deer don’t eat it, so fencing isn’t needed (except in my garden, where my dogs have developed a taste for it).
Asparagus spear
And pests are rarely a problem. Except for weeds.

Perhaps you’ve been put off by the heroic measures for planting it suggested in older gardening books. That is, digging a deep trench, planting the roots in the bottom of the trench, and then gradually filling it in as the plants grow. Not necessary!

The deep planting suggested was to keep the plants’ crowns beyond the reach of tractors’ cultivator blades. But there’s no reason to cultivate an asparagus bed, and most home gardeners don’t anyway, so make holes just deep and wide enough to cover the roots when planting.

So there you have it, for easy gardening and tasty meals: Plant Caucasian mountain spinach and asparagus, and perhaps, especially if you like the name, Good King Henry.

COVID-19 OR NOT, THE GARDEN MARCHES ON

A Special Week

Coronavirus has come, and it will go, but the natural world soldiers on. My dogs, Sammy and Daisy, are as happy as ever, oblivious to the pandemic. My garden will respond likewise, trucking forward and offering a centering point as the world around has its ups and downs.

This week is a very special one in my gardening year; it’s the week I plant peas. April 1st, to be specific. It’s sort of the official beginning of the vegetable garden. “Sort of” because actually have been planting and harvesting lettuce, mâche, arugula, claytonia, kale, bok choy, chard, and celery all winter in the greenhouse.Peas in pod

Not Too Early, Not Too Late

For some gardeners, St. Patrick’s Day is the date for sowing peas. Yes, that is the correct date for pea sowing — in Ireland, Virginia, and other places where I imagine soil temperatures reach about 40° F by that date. Above 40° F, and pea seeds become most likely to sprout rather than rot. On the other hand, waiting too long to plant pea seeds has the plant bearing during hot weather; peas don’t stand the heat well.

I mostly plant shelling peas, which are admittedly more trouble because they need shelling. To me, they’re worth it, for their flavor. (Then again, with the pandemic, more people are spending more time at home; gather ‘round and let’s shell peas.) I recommend the very tasty varieties Green Arrow and Lincoln.

My pea plants grow right up the center of 3-foot-wide beds. I make two furrows a couple of inches deep, one on either side of a bed’s center, and 4 inches apart. The seeds go in a couple of inches apart.
Pea seeds in furrows
Pea plants are sometimes available as transplants, or, as my neighbor used to call them, “starts,” in cell-packs. Don’t buy them. Peas are a vegetable for which you sow the seeds directly in the garden. The reason is that the yield from a single plant, even six plants in a cell-pack is too minuscule to be worth it. And pea seeds sprout readily. Have some faith.

Once seedlings poke up through the ground surface, I put a trellis up the middle of the row. My trellis is temporary, able to move around the garden, just as do the pea plants, to a different bed each season. I pound a metal post into the ground at each end of the row, and then weave 3 foot high poultry netting (“chicken wire”), inch-and-a-half mesh, onto the posts. I use fiberglass electric fence posts, but any thin stakes woven at intervals into the netting and pushed into the ground keeps the fence from being floppy. After the final harvest, I pull up the pea plants, pull up the thin stakes, remove and roll up the netting, and pull up the end posts for use next year.
Peas on trellis
A number of other seeds can be planted on that seminal (for here) April 1st pea planting date. Those would include, except celery, the vegetables I mentioned above that have been growing in the greenhouse all winter. Radishes could also be included here, and spinach. And potatoes, as 2 ounce, whole tubers or pieces of cut tubers.

Best Tomatoes For . . . ?

Also significant about April 1st on my gardening calendar is that it’s my date to sow tomato seeds, indoors in seed flats. It’s not that tomato is my favorite garden vegetable; it’s just that it’s such a popular vegetable and perhaps the most versatile.

For a cherry tomato to just pop right in my mouth or put in salads, I grow Sungold. That’s all they’re good for, but they’re really, really good for that.

Sungold, hands down the best tasting cherry tomato

I dry many varieties, especially Amish Paste and Anna Russian. Some of them also go into jars, along with San Marzano, arguably the best tasting tomato for canning. (In Italy, cans of tomato made with San Marzano tout that on the label.) Blue Beech is another variety, this one with a unique flavor, that I both can and dry.
Canned tomatoes
For good, fresh eating and very pretty tomatoes, I’m growing Nepal, Carmello, and, with a bright orange skin, Valencia. All three varieties are round tomatoes with smooth, crack-free skins.

Valencia tomato

For the very best in fresh eating tomatoes, there are many to choose from. I’m growing Paul Robeson and Pink Brandywine this year, although many others, such as Belgian Giant, Cherokee Purple, or others with “Brandywine” in their name could also fill the bill. Extras of these and the previous mentioned “good, fresh eating” varieties go into sauce, but not, of course, the dedicated San Marzano batches. Besides being good for cooking and drying, Amish Paste and Anna Russian are also good fresh. Not San Marzano, though; it’s awful raw.

As with pea planting, my tomato-sowing date is not for everyone; what is for everyone is to sow the seeds about 6 weeks before the local “average date of the last killing frost,” a date that is available online or from the local County Cooperative Extension Office. Sowing on this date strikes a nice balance between plants being small enough to make a smooth transition out to the garden and being sufficiently large for a timely first harvest.

April 1st isn’t the date to start all transplants. I sowed onion seeds way back in early February, and pepper and eggplant seeds in early March. For an early crop of cucumbers or melons, I’ll sow those in early May for transplanting at the end of the month. Or I’ll plant the seeds directly in the ground sometime soon after the “last killing frost” date. (I made a whole chart of vegetables and garden sowing, indoor sowing, and transplanting dates, keyed to whatever anyone’s “last frost date” is, in my book Weedless Gardening.)

Take Care

The garden marches smoothly forward, snubbing its nose at the pandemic. We can do likewise if we stay home if possible, wash our hands frequently and thoroughly and keep them away from our faces, and protect ourselves and others if we must go out. Consider that everything you touch off-site could be contaminated, or could be made so by you.

VEGETABLE MATTERS

Homebound? Plant Vegetables!

Working from home, I’m used to being homebound. And I like it. Not everyone feels this way, and now COVID-19 has forced this situation on many people.

For anyone who isn’t growing some vegetables, if there ever was a time to start a vegetable garden, it’s now. 
Vegetable garden
A garden will provide pleasant and interesting diversion, some exercise, a chance to be outdoors, the need for less frequent trips to the market, a good family project/activity, and some savings of food dollars. And the experience of — wonder of wonders — watching seeds sprout and grow into plants.

Growing vegetables is easy. Seeds have been practicing sprouting for millions of years. That’s what they do. Sprout. And plants have been doing likewise. 

Paying attention to some basic plant needs will make your garden even more successful. As far as soil, don’t worry about fertility or acidity for now. The most important consideration is drainage. That is, does water move down through the soil or does it just sit in place for a long, long time.

What’s a “long, long time?” If you really want to know, cut the bottom and top off a coffee or similar can, and set the can into a hole a few inches deep, pushing it into the soil (not if it’s frozen) in the bottom of the hole. Fill the can with water, let it drain, then fill it again. If the water level  drops slower than 1” per hour, drainage is poor. Find another site or make raised beds.
Measuring water drainage
No backyard or front yard in which to grow vegetables? No problem. Grow them in a tub or flowerpot. Pay attention to drainage even if your “garden” is a tub or a large flowerpot. The container must have drainage holes in its bottom to let water drain out. And you’re going to fill that container with “potting soil,” not with dirt from your garden. Water can’t drain well through garden soil in the confines of a container, which is why potting soils have, among their ingredients, perlite, vermiculite, or other mineral aggregate to speed water flow.

Whether in a container or in your front or back yard, vegetables need sun, about 6 hours of direct summer sunshine daily. 

Soil Matters

Next, ready the ground. For most newbies, that means transmuting a patch of lawn to a vegetable garden. There are two options. The first is the traditional one, turning over and mixing up the top few inches of ground to kill existing vegetation and leave a surface in which you can plant seeds. Do that, using a shovel, garden fork, or rototiller as soon as the soil is dry enough to crumble, not wad up, when squeezed gently in your hand.

Me, rototillingWait two weeks for Mother Nature to work her magic decomposing some of that existing vegetation. Or, rather, part of her magic. After two weeks, dig up the ground again, this time adding some compost or fertilizer. You could dispense with the compost or fertilizer this season if whatever was growing there before digging looked vibrant. Better not to go out to a store these days if you don’t have to anyway. Wait another two weeks, and when you’re ready to plant, use a garden rake to tickle the surface of the ground and crumble it.

Digging up the ground may be a nice way to get your blood pumping on a spring day, and may even give you a feeling of righteousness, but there’s a better, quicker, and easier way, to prepare the garden site. There’ll also be less weeds in weeks to come.

For option number two, you will need a supply of compost and either wood chips, straw, sawdust, or wood shavings. This option is easy: just cover the garden area with newspaper, four sheets thickness and overlapping, and then wet the newspaper to keep it from blowing away. Mark out 3 foot wide beds and 18 to 24” wide paths with string, and lay an inch or more of compost in the bed areas, and enough of the wood chips, straw, sawdust, or wood shavings in the paths to cover the paper. You’re all set to plant!
spreading wood chips in path
In most places, but not everywhere, a fence is needed to fend off rabbits. Two-foot high chickenwire (“poultry netting”) will do the trick.

(All this, and more, in my book Weedless Gardening.)

What to Grow

What to grow is a matter of taste. Kale, collards, and Swiss chard offer maximum nutrition and a very long harvest season. For some home-grown calories, potatoes and sweet corn. For rounding things out with great flavor, tomato, eggplant, pepper, cucumbers. Think about what you want to grow, look at seed catalogues, order seeds, and when we next cross paths, I’ll say something about timing.

Inspiration and Humor for the Pandemic

In these times of pandemic, the insouciance of animals and the humor they offer (and washing hands, social distancing, and covering up coughs and sneezes) is welcome. Here is a short video clip of my ducks:

ALL ABOUT ONIONS

/10 Comments/in /by

An Ode

Onions, how do I plant thee? Let me count the ways. I plant thee just once for years of harvests if thou are the perennial potato or Egyptian onion. If thou are the pungent, but long-keeping, American-type onion, I sow thy seeds in the garden in the spring. And if I were to choose like most gardeners, I would plant thee in spring as those small bulbs called onion “sets.” (Apologies to E.B. Browning)

New Old Ways with Onions

Early March brings us to yet another way of growing onions: sowing the seeds indoors in midwinter. This was the “New Onion Culture” of a hundred and fifty years ago, and, according to a writer of the day, “by it the American grower is enabled to produce bulbs in every way the equal of those large sweet onions which are imported from Spain and other foreign countries.” This is the way to grow the so-called European-type onions.

Walking onions

Walking onions

What’s wrong with growing perennial onions, American-type onions, and onion sets? Neither perennial nor American-type onions have the sweet flavor of the famous Vidalia onion, a European type. And onions for sets are generally limited only to the two varieties marketed, Stuttgart and Ebenezer, whose important quality is that they make good sets. A few seeds companies sell sets of a better variety, Forum. In addition to variety, quality of sets is important: too large and they become useless as they send up seedstalks.

The New Onion Culture is a way to grow the large, sweet, mild European onions, such as Sweet Spanish.

The “Method” is as follows: About 10 weeks before the last hard freeze, fill a seed flat with potting soil and use a plant marker to make furrows 1/2-inch deep and one inch apart. Drop about seven seeds per inch into the furrows and then cover the seeds with soil. Fresh seed, less than a year old is best. Water the flat, then keep it moist and warm and covered with of pane of glass. The onions should sprout in a week or two.

Once the onions sprout, remove the plastic or glass and give the seedlings plenty of light. Put the flat either within a few inches of fluorescent lights, on a very sunny windowsill, or in a greenhouse. Each time the seedlings grow to six inches height, clip them back to four inches. The trimmings, incidentally, are very tasty. This indoor stage of plant growing can be bypassed by purchasing onion transplants (not sets), which are sold mail-order in bundles of twenty-five.

Get ready for transplanting a few weeks before the predicted last freeze date. Choose a garden spot where the soil is weed-free, well-drained, and bathed in sunlight. Onions demand high fertility; my plants go into a bed that was dressed with an inch depth of compost last fall. Give the onion seedlings their final haircut, tease their roots apart, then set them in a furrow, or individual holes dibbled with a 3/4-inch dowel. Plant seedlings two to four inches apart, two inches if you want small bulbs, four inches if you want big bulbs. 
Onion growing cycle
This may sound like a lot of trouble to grow onions. But for me, midwinter onion sowing inaugurates the new gardening season. The onion is an apt inaugural candidate; it responds to “high culture” starting with careful sowing in fertile soil and moving on to good weed control, timely watering, and, after harvest, correct curing after harvest. 

Besides providing this midwinter ritual, onions raised according to the New Onion Culture do have superb flavor.

(The above was adapted from my book A Northeast Gardener’s Year.)

And Still Newer Ways

And now for the “Newer Onion Culture”: American-type onions have the advantage of being better for long-term storage, and newer varieties also have very good flavor. My current favorites are Copra, Patterson, and New York Early. They also are “long day” onions, setting bulbs when the sun shines for 15 to 16 hours daily. “Short day” varieties, which are adapted to the South, would bulb up too soon around here, producing puny bulbs.

There’s more to the “Newer Onion Culture.” A couple of years ago, a local farmer, Jay, of Four Winds Farm, told me he gets good results by just planting seeds in furrows right out in the field.

And even more. Instead of planting 7 seeds per inch indoors in furrows in early March, sow them in flats of plastic “cells” with 4 seeds per cell (each cell is about an inch square). Onions seedlings in cellsWhen transplanting out in the garden, plant each cell with its seedlings intact, spacing them further apart than you would with individual transplants so their roots get adequate water and nutrition. As vegetable growing maven Eliot Coleman wrote in Four-Season Harvest, “the onions growing together push each other aside gently.”

Back to my original query: “Onions, how do I plant thee.” Many ways. I’ll do four out of the six ways this season.

I Think My Vegetables are Nutritious

Nutrient Declines in Fruits and Vegetables

Growing vegetables is really quite simple. You put the seeds or transplants into sunny ground, you water and weed, and then you harvest your bounty. For that small effort, you can put on your plate food that is organically, sustainably, and (very) locally grown. Perhaps even richer in nutrients than food you can buy.
Healthy, healthful, vegetables
Studies over the past 15 or so years have documented a general decline in nutrients in our fruits and vegetables. Some people contend that our soils have been mined for their nutrients, worn out from poor farming, and therefore no longer able to provide us with nutritious food. The cure, according to these “experts,” is to sprinkle mineral-rich rock powders on the soil to replenish and rebalance that which has been lost. It all sounds very logical.

You might have sensed a big “but” looming. Here it is: But . . . further studies have pinned that nutrient decline on a dilution effect from increased yields. Pump up production with nitrogen fertilizer and water, or by breeding for increased yields, and nutrient concentrations decline; it’s as simple as that.

The final nail in the “worn out soil” coffin comes from side-by-side plantings of low- and high-yielding varieties of specific vegetables. The higher yielding varieties end up with lower concentrations of minerals and protein. The problem, then, if there is one, can be blamed on breeding and farming practices aimed at producing more bulk.

But . . . 

I’m not concerned with nutrient decline in my own garden. First of all, I’ve chosen the varieties I grow — Blue Lake beans, Cherokee Purple tomatoes, Lincoln peas, Early Jersey Wakefield cabbage, Ashmead’s Kernel apple, and Fallgold raspberry, as examples — with

one thing in mind: flavor! Peas in podIt just so happens that the most flavorful fruit and vegetable varieties are ones that have been around a long time. Yields may not be heavy, but these varieties are rich in flavor. (And perhaps nutrients. Anyway,

Ashmead's Kernel apple

Ashmead’s Kernel apple

if something doesn’t taste that good, I’m not going to eat much of it, so it’s irrelevant how high it is in nutrients.)

I’m also not concerned with nutrient decline because I don’t push yields to the max with repeated applications of soluble, nitrogen-rich fertilizers. My soil management is simple: One inch of compost per year spread on top of the ground of permanent vegetable beds; compost, wood chips, hay, and/or leaves around my fruit plants. As these organic materials decompose, nitrogen and other essential nutrients are bled slowly into the soil only in response to warm temperatures and moisture, the same environment that spurs plant growth.
Spreading compost
That compost is not serving up only nitrogen to my plants, or even just the big three nutrients, nitrogen, phosphorus, and potassium. Into my compost goes orange peels from Florida, avocado skins from California, and other kitchen waste, garden trimmings, some weedy hay, and, occasionally, horse manure. So the ground gets a wide variety of organic materials that, in turn, feed the compost and, in turn, feed the soil and the plants a wide spectrum of nutrients. And just to make sure that my soil lacks nothing, I occasionally sprinkle some powdered kelp around.

Herbs for Flavor, in Winter, Not Nutrition

Even if herbs were rich in nutrients, their nutritional contribution to our diets would be minimal because of the relatively small amounts actually eaten. But the small amounts needed to pizazz up a tomato sauce or frittata in winter also make herbs ideal for growing indoors in winter. A little goes a long way. 

The basic problem is that many cooking herbs are Mediterranean plants that, of course, thrive best in Mediterranean conditions, with bright hot sun beating down on them. So the expectations and the reality of a windowsill herb garden often diverge. Forget about growing basil or oregano in January.

With that said, I nominate two herbs perfect for indoor growing in winter. The first is bay laurel. This plant, a small tree trained as a “standard,” has spent the last 29(!) winters near a sunny window. A freshly plucked leaf brings to soups and stews a flavor only hinted at by the dried leaf; to me, in addition to its distinctive flavor I sense an oleaginous quality hinting of olive oil.

The second herb, rosemary, is my favorite for indoor growing. Rosemary tolerates being trained as a standard or fanciful topiary; it looks equally good left to its own devices to grow as a relaxed, small shrub.  (Mine are trained as standards.) Pinching off a few stem tips

Small, indoor rosemary "tree"

with leaves not only puts some warm, Mediterranean sunshine into tomato sauce but also encourages growth of side shoots to keep the plant dense with shoots and leaves.

 

Once spring warmth has settled in around here, the bay laurel and rosemary will move outside to bask in the full force of Hudson Valley sunshine. 

What Midwinter, Spring-like Weather Will Do

/0 Comments/in , , /by

My Garden’s A Mess!

After some really frigid weather a month ago followed by more or less seasonal cold, temperatures did a loop de loop and we’ve had a couple of days in the high ‘60s. Very unseasonal, to say the least, and perhaps another indication of global warming, but welcome nonetheless. Those temperatures, coupled with brightening sunshine, made me want to get my hands in some dirt.

A large, second-story bedroom window overlooks my main vegetable garden. The weather made me see it in a different perspective — it looked messy. 

I pride myself on putting everything in order each fall so that (quoting from Charles Dudley Warner’s 1886 My summer in the Garden) “The closing scenes are not necessarily funereal . . . A garden should be got ready for winter . . . neat and trim. . . in complete order so that its last days shall not present a scene of melancholy ruin and decay.”

Messy garden, January

Not a pretty picture

Endive, dead in January

Endive, dead in January

Although I had mostly cleaned up spent vegetables and dressed the beds with an inch-deep layer of compost, early wintry weather put an end to that. Now, what I saw outside was too much “melancholy ruin and decay” from a few beds of late cabbages and their kin and tunneled beds of endive. The wilted, dried, browned leaves of unharvested endive lay flat, covering those beds.

Spring-like temperatures offered me the opportunity to get my hands in the dirt. I grabbed my hori-hori knife and gathered up frozen or dessicated leaves and plants for carting over to the compost pile. What a shock to even find some signs of life still out there in the beds: some arugula, some kale plants, and a couple of plants of baby pak choy and michili Chinese cabbage.
Michili chinese cabbagePak choy in garden, January
Coldest temperatures (minus 20 degrees F. here) typically arrive in late January. Those temperatures will do in these plants. Except for mâche, of course, which was also still alive in the garden, spry and green as if temperatures had never already dropped near zero, and which always survives winter.

First Seeds

That spring-like weather also gave me the urge to sow some seeds. These would be the first of the year, a seed flat of lettuce and baby pak choy to mature in early spring in the greenhouse. For some irrational reason, I’m never that confident that those tiny specks are actually going to sprout, even though I’ve done this successfully for decades.

Perhaps my lack of faith comes from my first experiences sowing seeds. That was many years ago when, as a graduate student, I lived in a motel room that had been converted into an apartment and began my first garden as an adult. I sowed all sorts of vegetable and herb seeds in peat pots that I set in trays on a shelf on a wall near a window.

All those seedlings died — and that was my abrupt introduction to “damping off,” a disease that attacks seeds and newly emerged seedlings. Imagine the disappointment of a beginning gardener (me) watching seedling stems pinch in at he soil line and topple over — the telltale symptom of damping off disease.
Damping off, cabbage

First Disease

I soon learned that damping off was not uncommon, even among experienced gardeners. The disease is caused by any one of a few soil dwelling fungi that raise their ugly head (figuratively) given the right conditions (for them). One obvious way to try to avoid the problem is to sterilize the potting media.

Most commercial potting mixes are sterile, as were the peat pots I was using. The problem is that the culpable microbes are everywhere, waiting to attack when conditions are just right, conditions that I unknowingly provided in my motel room. The peat pots were excessively moist; the air stood still; and little light entered the room — perfect for damping off development.

Nowadays, my seedlings rarely experience damping off. The plants get off to a good start at temperatures they enjoy, bathe in light in my greenhouse or sunny windows (or, in the past, cozied up very close to fluorescent bulbs), and a fan keeps the air moving. I also add sufficient perlite to my potting mixes so that excess water drains feely down and out of the mix. A thin layer of well-draining material, such as sand or calcined montmorillonite clay (kitty litter) can also help.

Years ago, soothing brews of chamomile tea would also come to the rescue — for the seedlings, not for me. That tea hasn’t been needed for a long time. I also don’t pasteurize or sterilize my potting mixes. Beneficial microbes, from the compost in my mix, and good growing conditions have thankfully made damping off nothing more than a distant memory for me.

Catalog and Weather Watchin’

/15 Comments/in , , /by

Armchair Gardening

Pretty much the only “gardening” I’m doing now is thumbing through the seed catalogs arriving in dribs and drabs in my mailbox. I’ve ordered and received what I thought I’ll need, but you never know; maybe there something else interesting out there to grow.

Among the most fun of these catalogs, and strictly for the plant-crazed, is “The 2020 Ethnobotanical Catalog of Seeds,” which used to be called Hudson’s Seed Catalog. The catalog originates in the Santa Cruz mountains of California (once home to Ken Kesey) but offers seed from all corners of the world. Only recently have they come online, at www.jlhudsonseeds.net.
Hudson catalog
I’ve ordered from this catalog for decades, each winter pleasurably and slowly wading through the almost 100 black-and-white pages of small print listings of botanical names and descriptions. For this first run through the catalog, I sit poised with red pen, ready to make a star next to any seed listing that looks particularly interesting. After I go through the whole catalog once, I’ll re-examine all those starred listings and select which seeds to actually order and grow.

Judging from what I’ve so far starred, I seem this year to be drawn to scented plants. Achlys triphylla, also known as vanilla-leaf or sweet-leaf, is one such plant: “Dense spikes of tiny flowers held above the trifoliate fan-shaped leaves. Moist woods from B.C. to California. The sweetly fragrant leaves were highly valued by settlers, who hung bunches in their houses. Sow 1/4″ deep in rich woodland soil, and keep moist. Slow to germinate.”

Another is Adenophora lilifolia, also known as ladybells. This one is described as “sweet-scented light blue 1/2″ wide bell-shaped nodding flowers borne profusely in summer. Very hardy perennial to 1-1/2 to 3 feet, with round, heart-shaped basal leaves. Eurasia. Cultivated in Japan for the thick, edible roots. Germinates in 2 weeks.” For only $2.50 a seed packet, oodles of each of these plants can be growing in and perfuming my backyard this summer.

  It’s not just visions of fragrant, comely, or tasty plants that make this catalog fun to read. Berkheya purpurea is native to Africa, with a common name Zulu warrior. How many plants conjure up an image like that!? The plant seems to me less warrior-like, with flowers that are large, silvery-blue to lavender daisies with dark centers. Interesting, but I don’t need another daisy for now. 

Short quotes interspersed throughout the catalog set the tone and are food for further thought. Here’s one from Thomas Jefferson: “It does me no injury for my neighbor to say there are 20 gods or no God. It neither picks my pocket nor breaks my leg.” Or, going back 17 centuries, to Aesop: “Any excuse will serve a tyrant.” And then forward, to General Douglas MacArthur: “ If you win, you stand only to lose. War contains the germs of double suicide.” Or, to another American general, Dwight Eisenhower: “Things are more like they are today than they have ever been before.”

  So far, I’ve only gotten as far as “D” in the seed listings. There’s still time.

Where’s Winter?

Aren’t temperatures supposed to get colder and colder and colder until the end of this month, and then get warmer and warmer and warmer? That’s how temperatures generally trend in coastal regions, near large bodies of water, and in western Europe. Not so here in the Hudson Valley and over most of continental North America.
Current winter scene
In my garden, the low was 3 degrees in early December and the high was 59 degrees a couple of weeks ago. Such fluctuations are not that uncommon over much of continental U.S. If you don’t like winter, you welcome those balmy winter days; if you like winter and/or like plants, those balmy days make you shudder.

  Plants that can take our cold weather like the weather to stay cold all winter. Each time temperatures warm, especially after we’ve had a spell of cool weather, these plants start to awaken slightly from their winter slumber. The closer to spring and the warmer the weather, the more they awaken. Problem is that the more awake a plant is, the more likely damage, even for a cold-hardy plant, from subsequent frigid weather.

  All this makes a good case for growing native plants. They’re more used to our mercurial weather and know better than to let a winter warm spell entice them out of their slumber.

  However, many cultivated plants are not native. I like to grow fruits, and any fits of warm weather in weeks to come are going to make me nervous about the apples, plums, hardy kiwis, and pears, all non-native and sometimes awakening early enough to be damaged by subsequent cold.

Blueberries, pawpaws, persimmons, raspberries, and mulberries should be fine. Let’s hope for steadily cold weather and plenty of snow for the rest of winter.

SEED TIME

/14 Comments/in , /by

Late this Year

This year I’m late, but not too late, with my seed orders. Usually, I get them in by a couple of weeks ago.

The only seeds that I’ll soon be planting are those of lettuce, arugula, mustard, and dwarf pak choy. They’ll fill any bare spaces soon to be opening up where winter greens have been harvested. No rush, though, because I have seeds left over from last and previous years of these vegetables, and they keep well if stored under good conditions.
Greenhouse greens
I’ve usually sowed onion seeds early also, in flats in the greenhouse in order to give plants enough time to become large transplants. Large transplants translates to large plants out in the garden before long days force them to shift from growing leaves to, instead, swelling their bulbs. More leaves before that shift makes for larger bulbs.

Last year, because of poor onion germination in the flats, I ended up getting fresh seeds and sowing them directly in the garden in early spring. Keeping the bed moist promoted quick germination and, by August, the bulbs stood up well, size-wise, to those from seeds sown in the greenhouse in past Februarys.

Seed Longevity

Onion and leek seeds don’t keep very well. Viable seeds are living, albeit dormant, embryonic plants which do not live forever. Conditions that slow biological and chemical reactions, such as low temperature, low humidity, and low oxygen, also slow the aging of seeds.

Seeds differ in how long they remain viable. Except under the very best storage conditions, it’s not worth the risk to sow onion, parsnip, or salsify seeds after they are more than a year old. Two years of sowings can be expected from seed packets of carrot and sweet corn; three years from peas and beans, peppers, radishes, and beets; and four or five years from cabbage, broccoli, Brussels sprouts, cucumbers, melons, and lettuce. 
Chart of vegetable seed longevity
Among flower seeds, the shortest-lived are delphinium, aster, candytuft, and phlox. In general, though, most annual flower seeds are good for one to three years, and most perennial flower seeds for two to four years. 

In a frugal mood, I might do a germination test for a definitive measure of whether an old seed packet is worth saving. Counting out 10 to 20 seeds from each packet to be tested, I spread them between two moist paper towels on a plate. Another plate inverted over the first plate seals in moisture and the whole setup then goes where the temperature is warm, around 75 degrees.

After one to two weeks, I peel apart the paper towels and count the number of seeds with little white root “tails”. If the percentage is low, the seed packet from which the seeds came gets tossed into the compost pile. (I don’t give them away!). Or, I might use the seeds and adjust their sowing rate accordingly. 
Seed testing
No one knows exactly what happens within a seed to make it lose its viability. Besides lack of germination, old seeds undergo a slight change of color, lose their luster, and show decreased resistance to fungal infections. There’s more leakage of substances from dead seeds than from young, fresh seeds, so perhaps aging influences the integrity of the cell membranes. Or, since old seeds are less metabolically active than young seeds, the old seeds leak metabolites that they cannot use.

Finally, Get My Orders In

Today I dug out my shoeboxes of seeds from the unheated workshop and noted what was missing and what was too old.

Needed still are yet undetermined, good varieties of Brussels sprouts, celeriac, semi-hot pepper, and melon. (Any suggestions for good varieties?) Also one or more packets of Bartolo cabbage, Blues Michili cabbage, Shintokiwa cucumber, Golden Bantam 8-row sweet corn, Blacktail Mountain watermelon, Carmen pepper, Mammoth sunflower, and Empress of India nasturtium.
Ordering seeds
And, of course, some tomato varieties need replenishment: Sungold, Anna Russian, Nepal, Carmello, San Marzano, and Amish Paste. They will join Belgian Giant, Pink Brandywine, Paul Robeson, and Blue Beech out in the garden.

A colorful and flavorful growing season is in the offing.

The End

/11 Comments/in /by

Snow Day

On December 2nd, my gardening season officially ended. It was brought to a screeching halt as a foot of heavy, white powder descended to democratically blanket my meadow, my vegetable beds, my terraces, and my deck.
Snow in garden, Dec. 4
I have to admit that it was welcome as I had spent the previous few weeks furiously getting ready for the end. Compost now covers most of the vegetable beds. Wood chips and neighbors’ raked leaves lie thickly beneath berry bushes and recently planted Korean pine (for nuts), chestnut, and pear trees.

Left in place, the one tunnel protecting a bed in the vegetable garden would have been collapsed by a heavy snow; I dismantled it. This tunnel consisted of metal hoops, 4 feet apart, each 5 feet long with either end pushed into the ground at each edge of the bed. The row of hoops was covered with vented, clear plastic and then, for added cold protection, a layer of “row cover” (a diaphanous fabric that lets air, water, and some light penetrate while affording a few additional degrees of cold protection).
Clear plastic tunnel
I secured the clear plastic and the row cover layers by “planting” another metal hoop over them, right where the first hoops were”planted.” This setup makes it easy to slide the layers up and down, as needed, to reach in for harvest.

After dismantling the hoops and coverings, I picked over what remained. Cold  had turned the few heads of lettuce left in the tunnel to mush. Surprisingly, a few small heads of pac choi (the varieties Joi Choi and Prize Choi) and large heads of napa type Chinese cabbage (the variety Blues) were in pretty much perfect condition.

My surprise came about because I had checked my minimum-maximum thermometer which registered the minimum temperature this fall as having dipped as low as 11° Fahrenheit. That’s very good protection from a thin layer of clear plastic topped by a layer of row cover — coupled with what are evidently quite cold-hardy varieties of Chinese cabbage.

Cloche History

Cold protection has come a long way since I started gardening. Over the years, cold protection devices, commercial and home-made, have undergone various incarnations in my gardens. Early on, with a bow to traditional cloches, I cut bottoms off gallon glass jugs for mini-greenhouses over individual or groups of very small plants.

(Cloche, pronounced klōsh, is the French word for “bell.” The original cloches were large bell-shaped jars that 19th-century French market gardeners placed over plants in spring and fall to act as portable miniature greenhouses. At one time, these glass jars covered acres of fields outside Paris that supplied out-of-season vegetables to the city’s households and restaurants.)

The classic glass bell jars are still available but have some significant limitations. Because they’re made from heavy glass and are small, the air trapped within can quickly get too hot on sunny days, cooking plants. And close attention needs to be paid to ventilation. A professional gardening friend, trained many years in France, tells of trudging out to cloche-covered fields on bright, frosty mornings to slide a block of wood under one side of each cloche to vent it during sunny days. In late afternoon he’d walk the field kicking out the blocks, setting each cloche flat on the ground to seal the warm air in for the night.

Although modern versions of these individual cloches are not as elegant as the traditional glass bell jars, some offer the same or a better degree of frost protection, are made of lightweight materials, are easier to vent, and are more convenient to store.

Modern variations on the cloche include: Clear umbrellas, which fold and unfold for easy storage, with spike handles that hold them in place; lightweight, durable, and inexpensive plastic versions of the traditional glass jar cloche; plastic milk jugs with the bottoms cut and vented by opening the lid; waxed-paper Hot Kaps. These vary in the degree of cold protection they offer as well as the size of the area they protect.

Tunnel type cloches protect whole rows or beds of plants. My original tunnel cloches were ersatz, British-made Chase cloches, which cleverly held glass panes into a ventable barn shape. Placed end to end, they created a tunnel, mini-greenhouse. I originally made my own from straightened coat hangar wire, then got hold of the real thing.

Problem was, I discovered, that they work best in climates where temperatures are moderated, such as in northern Europe or near large bodies of water. (Anybody in those locations want some Chase cloche wires?)

So I graduated to the much more effective but much less attractive tunnel cloches, or “tunnels,” I described above.

YOGI WAS RIGHT

To Do List

“It ain’t over ’til it’s over” said Yogi Berra, and so says I. Yes, the outdoor gardening season is drawing to a close around here, but I have a checklist (in my head) of things to do before finally closing the figurative and literal garden gate.

Trees, shrubs, and woody vines can be planted as long as the ground remains unfrozen. To whit, I lifted a few Belaruskaja black currant bushes from my nursery row and replanted them in the partial shade between pawpaw trees. A Wapanauka grape vine, also in the nursery row, is now where the Dutchess grape — berries too small and with ho-hum flavor — grew a couple of months ago. And today a couple of black tupelos are moving out from the nursery row to the edge of the woods, where their crimson leaves, the first to turn color, can welcome in autumn each year.

Kale, lettuce, endive, turnips, radishes, leeks, and celery still grow in the vegetable garden, but many beds are vacated for the season. Any remaining old plants will become food for the compost pile and the cleared off beds will then get a one-inch dressing of crumbly, brown compost from a pile put together last year.

Freezing weather would burst the filter, pressure regulator, and timer for the drip irrigation system, so these components have been brought indoors. The rest of the system stays in place.

The drip system may now be out of commission but some watering may be needed. Occasional days with bright sunlight and warm mean hand watering. How primitive!

Planning Ahead, Soil-wise

Making compost for use next year, same time, same place, is also on my checklist. Especially today, so the compost creatures within the pile can take advantage of lingering warmth in the air to work overtime. A pile that gets hot cooks to death most weed seeds and pests that hitchhike into the pile on what I throw in. And I throw in everything, in spite of admonitions from “experts” to keep diseased or insect-ridden leaves, stems, or fruits out of compost piles.

So today, after loading horse manure, with wood shavings bedding, into my truck pitchforkful by pitchforkful, I drove home and unloaded everything pitchforkful by pitchforkful into my compost bins. Each bin got a lot more than a restricted diet of just the horse manure mix, though. I alternated layers of manure with mowings scythed from my small hayfield, wetting down each layer well and sprinkling occasional layers with soil, for bulk, and ground limestone, to counteract soil acidity.
Compost bins
Manure is not a necessity for good compost. The manure mostly is for nitrogen, one of the two main foods of compost microorganisms. Some of my piles get that nitrogen from soybean meal, an animal feed usually meant for creatures that you don’t need a microscope to see. Early in the season, young grasses and weeds, which are high in nitrogen, do the same. And truth be told, any pile of plant material, if left long enough, will turn to compost. The nitrogen helps the material chug along faster on its way to compost, and the faster the microbes work, the hotter it gets.

Winter Work for Microbes

I’ll be feeding my last compost pile of the season all winter long. Just a little at a time, mostly scraps and vegetable trimmings from the kitchen with occasional toppings of leftover hay. Adding stuff slowly to a compost pile doesn’t let enough critical mass build up for heat, and especially not in winter’s cold.
Dog and chickens on compost pile
No matter. I just let piles that don’t heat up sit longer before I use them. It’s the combination of time and temperature that does in all the bad guys that hitchhike into my compost piles. So 1 hour at 140° F. might have the same deadly effect as a week at 115° F. My hot piles sit for a year before I use them; the cold piles cook longer. It ain’t over ‘til it’s over.
