Who’s the Best Gardener/Farmdener?

November 21, 2014/3 Comments/in Fruit, Gardening, Soil, Vegetables/by Lee Reich

Fresh Watermelon, and More, with Help from Ethylene

Could I possibly be the best gardener west of the Hudson River? Perhaps. As evidence: On November 1st, here in Zone 5 of New York’s Hudson River Valley, where temperatures already have plummeted more than once to 25°F, I was able to harvest a fresh, dead-ripe watermelon. Not from a greenhouse, not from a hoop house, not even from a plastic covered tunnel. Watermelon, a crop sensitive to frost and thriving best in summer’s sun and searing heat.

Okay, perhaps I can’t assume all that much responsibility for the melon. Let me explain . . .

Every fall, I have a landscaper dump a whole truckload of leaves vacuumed up from various properties at my holding area for such things. Rain and snow drench the pile in the coming months, starting it on the road to decomposition. When sufficiently warm weather has decided to stay in spring, I scoop out a few holes in the pile, fill them with compost, then tuck in watermelon transplants.

Last fall’s pile yielded well from summer until early fall this year, at which time I gathered up remaining melons for eating or, if unripe, for composting along with the vines. The tractor, with its bucket, was able to move and compact the now dense pile to make way for this year’s crop of leaves.

Ben & Jeremy show off the November watermelon.

Now we’re up to November 1st, time to spread the leaf mold before it freezes — a big job that necessitated enlisting the help of my neighbors Jeremy and Ben. We were loading and hauling and loading and hauling, forking deeper and deeper into the bowels of the pile, when Jeremy yelled that he’d just speared a watermelon I had overlooked when cleaning up. I cleaned it off and sliced it open. It proved to be a ripe watermelon. The taste? “Awesome,” to quote Jeremy.

The Watermelon Mystery

Okay, I admit to not being able to claim too much credit for the ripe watermelon. How did it get there? Was it ripe and overlooked, then buried and preserved in the warm bowels of the leaf mold pile? Was it unripe when buried, then subsequently ripened? Probably not. No leaves were poking out of the pile, capturing the sun’s albeit weak rays for photosynthesis to make the sugars needed for ripening. A couple of nights of 25°F would have done in the leaves anyway.

Some fruits can actually ripen after harvest. These include apples, pears, bananas, avocados, and other so-called climacteric fruits. Just before ripening, respiration of climacteric fruits dramatically increases along with a burst in production of the plant hormone ethylene. Through a feedback mechanism, ethylene stimulates more respiration which in turn stimulates even more ethylene production and even quicker ripening. Hence, enclosing bananas in a bag stimulates ripening, and why one rotten apple — injury, whether mechanical or from pests, also elicits an ethylene response — can indeed “spoil the barrel.”

This burst in ethylene production occurs even after climacteric fruits have been harvested, as long as they were sufficiently mature at the time. You can’t pick a golfball-sized green apple and expect it to ripen off the plant.

Non-climacteric fruits lack that pre-ripening spike in respiration and ethylene production, and do not ripen after harvest. Or so the thinking, based on early experiments, went. According to more recent research, fruits show various degrees of ethylene production. Watermelon is not a climacteric fruit, but at a certain point the white flesh within does release a burst of ethylene some time after which it morphs from bland and unripe to sweet, red, and ripe. But that won’t happen off the vine.

(“Ripe” is open to some debate. Peach, for instance, is a climacteric fruit that, if picked sufficiently mature but underripe, will soften and become more edible. But it won’t develop the aromatics of a tree-ripened fruit or, until rotting changes starches to sugars, become at all sweeter after picking. I don’t call that “ripe.”)

So my watermelon must have been overlooked and ripe and evidently kept perfectly well in the moist warmth of the leaf pile.

Deb & Ethylene Take Credit for the Peppers

Ethylene, and not me, is going to take credit for the fresh, sweet red peppers in today’s salad. Peppers are a climacteric fruit. Green peppers are unripe peppers, but if the fruits have just a hint of red on them, they can ripen even after harvest to full red (or yellow, orange, or purple, depending on the variety of pepper) color and, at least to my taste buds, flavor.

Still eating fresh, red, ripe sweet, juicy, delicious peppers.

Skill is needed to ripen peppers off the plant. Cool, but not too cool, temperatures hold the fruits for storage and warmer temperatures then speed ripening. Just the right amount of humidity is also needed to, on the one hand, avoid drying, or, on the other hand, rotting. My wife, Deb, rather than I, plies these skills, so should probably get credit for the ripe, red peppers.

This season has been the best pepper season ever, both in quantity and in quality. King of the North peppers, large and blocky, with thick, juicy walls, now ripening in a basket taste as bland now as they did all summer. I won’t grow them again. In contrast, Carmen, Sweet Italia, and (slightly hot) Pepperocini peppers, also ripening in that basket, taste as good now as their siblings did snapped from plants basking in summer heat and sun a few months ago.

FIGS, POMEGRANATES, LETTUCE, BEDS: ALL READY

October 31, 2014/6 Comments/in Fruit, Gardening, Planning, Soil, Vegetables/by Lee Reich

Beds Ready for Spring Planting, Figs and Lettuces Readied for Cold

Much colder weather has been sneaking in and out of the garden but leaving traces of its presence with some blackened leaves on frost-sensitive plants and threatening to brazenly show itself in full force sometime soon. This fall I vow to put all in order before that event rather than, on some very cold night, running around, flashlight in hand, gathering and protecting plants.

Before even getting to the plants, drip irrigation must be readied for winter. Main lines and drip lines can remain outdoors but right near the spigot, the timer, the filter, and pressure reducer must be brought indoors where they won’t freeze. I plug the inlet for the drip’s main line to keep out curious insects. At the far end of the line is a cap that I loosen enough to let water drain out. Opening all other valves along the line leaves no dead ends in which freezing water could expand to break lines.

Begonia, amaryllis, Maid of Orleans jasmine (Jasminium sambac), and other topical plants are next in importance. Being near the radiating warmth of the house has spared them recent slightly frosty nights. Colder temperatures would not be so kind. I snap the stems off the begonias right at ground level and put the pots in the basement where cool temperatures will keep the tubers dormant to wait out winter. Amaryllis plants also go into the basement. Cool temperatures and lack of water for a couple of months give these plants the rest period they need so that, brought upstairs to a warm, sunny window, their blossoms can show off their bright, red color against the achromatic winter landscape beyond.

Maid of Orleans jasmine right away gets a prominent place in a sunny window to share its nonstop, sweet fragrant blossoms.

Figs, Pomegranates, & Subtropicals Readied for Cold, But Not Too Much

Fig, pineapple guava, Chilean guava, and pomegranate are subtropical plants that tolerate temperatures down into the ‘teens so can remain outdoors for weeks to come. Still, many of these plants are in large pots, not something I want to be lugging around following at last minute threat of frigid temperatures. So I’ll gather them together in a convenient location for quick dispatch indoors when needed.

Potted subtropical plants are getting ready for colder — but not too cold — weather

The guavas, as well as kumquat and common jasmine (Jasminium officinale), are evergreen subtropical plants. The leaves are important to these plants both for beauty and for function so they’ll make the move indoors before the other subtropicals to make sure their leaves go into winter undamaged.

Common jasmine stays out longest because some exposure to cold is needed to get blossoms in winter.

Cold Weather Vegetables for Weeks to Come

The vegetable garden is still green with endive, kale, lettuce, turnips, Brussels sprouts, arugula, and other cold-hardy vegetables. Soon, though, their cold tolerances will be tested. I’ll pre-empt that testing by covering some of the beds with tunnels of fabric (“fleece” to the Brits, “floating row covers” to us colonists) or clear plastic. No need yet to cover the plants but better to have the metal hoops which support the fleece or plastic in place and ready for the covering before that frigid night to come.

Metal hoops readied to support covers for lettuce.

Not all hardy vegetables get covered; just the leafy ones — lettuce, mustard, arugula, and endive — for fresh salads in the weeks to come. Brussels sprouts and kale are so cold hardy that they can go for weeks without protection, and, anyway, they’re too tall to cover. Leeks also can stay outdoors unprotected until December, or later, then get dug up and packed together in a box or large pot to store in the basement and use as needed.

Carrots, beets, turnips, and winter radishes enjoy the protection of the earth. With a deep mulch of leaves or straw, they could remain tender and unfrozen all winter. More convenient for eating is to dig them up just before really frigid weather descends on the garden and pack them in boxes with dry leaves to store in the cool temperatures of the basement. I’m putting off deciding which option to choose.

Fresh Lettuce ‘Til When?

Someone recently told me that they gardened maniacally all summer and now they are finished for the season . . . which reminds me of some more things that I still have to do. Plant garlic. I planted cloves back in early September; a second planting, now, will give some indication if early or late planting is better. Mulch blueberries as soon as their leaves all drop. Sift compost and garden soil into buckets to store for making potting soil in late winter. Cut down asparagus plants after the tops yellow, and mulch the bed. Clean up spent vegetable beds of tomatoes, peppers, and eggplants and spread them with an inch depth of compost. Mow hayfield and lawn to expose rodents to predators and, in the hayfield, to keep blackberry, sumac, and autumn olive from taking over. Plant bulbs (a large, naturalized planting of alliums; more on that some other time).

Beds readied for spring, and lettuce readied for winter

I’d also like to divide older plants in a flower bed and dig out weeds that are starting to think they’re home. And build a rustic fence to hid the propane tank for the greenhouse.

I’m not yet ready to throw in the trowel for this season.

COMPOST, FERTILITY, & SUSTAINABILITY

October 24, 2014/13 Comments/in Gardening, Soil, Vegetables/by Lee Reich

Compost and/or Living or Dead Organic Material = Sustainable Fertility

Maple leaves already dapple the ground in red and yellow (early this year), one morning showed off what was to come with frost on the windshield, and each day the sun each hangs lower in the sky, yet I’m getting ready for spring planting. Really! Yes, I’d rather do it now than in spring.

Beds of spent vegetables have been cleared. Okra plants, in this cool weather, just sat in place, hardly producing any new pods. So out went the plants. I severed the main roots with my hori-hori knife (www.oescoinc.com) and yanked out each stem. When corn is finished, it’s finished. Beds of early corn got replanted with endive, lettuce, and other late vegetables, but the latest beds of corn were harvested too late for replanting. Clearing away old vegetable plants not only clears the deck for next spring but also takes offsite some pests and diseases that might otherwise lurk around next year to do their evil work.

Clearing bed of all weeds and plants in preparation for its layer of compost.

With spent vegetable plants cleared away — tomatoes and peppers are still yielding fruits, so they remain for now — I remove weeds. Ideally, all of them. Left in place, annual weeds spread seeds and roots of perennial weeds grab more tenaciously and deeper into the soil. A single pigweed plant, for instance, can drop 120,000 seeds, poised and ready to invade next year’s garden. That, and the 36,000 seeds on every plantain plant, the 39,000 seeds of each lamb’s-quarter plant, and the 8,000 seeds clustered in a crabgrass seedhead prompts me to pull these weeds now, before more seeds mature.

Of course, some weeds escape my notice, so the final step in preparation for spring is to suffocate these: I slather each planting bed with a one inch depth of mostly weed-free compost. A temporary 2X4 at each edge of the bed keeps the compost neatly in place until patted down firmly.

The compost does more than snuff out overlooked weeds. Its biotic life helps protect plants against pests and diseases. It helps soils hold water and air. And it feeds plants a smorgasbord of nutrients.

On a Garden, Farmden, or Small Farm, Fertility Simplified

Did I mention spreading fertilizer, “organic” or otherwise, in getting the soil ready for spring planting? No. A one-inch depth of compost supplies all the nutrients needed to grow vegetables, even in beds with closely spaced plants. Paraphrasing the Beatles lyrics, “All you need is . . .compost, da, da, da-da da.”

Bed in middle has been lathered with an inch depth of compost, left on surface.

A garden is not Mother Nature left to her own devices; nonetheless, I try to emulate her as much as is practical. She does not spread fertilizer. Plants are naturally nourished as organic materials, such as leaves, stems, wood, roots, and dead animals, decompose to release whatever nutrients gave them life. I enjoy making compost and make enough to spread that required one-inch depth over all the beds.

Next best would be to spread some concentrated source of the most needed nutrients, that is, “fertilizer,” on the ground and supplement it with a mulch such as wood chips, straw, hay, or other organic material. Here, an organic fertilizer, such as soybean or alfalfa meal, has the advantage over a chemical fertilizer in that nutrients become available over a long time and are made so in response to temperature and moisture, in synch with plants’ needs.

Two advantages of maintaining fertility with compost rather than mulch plus fertilizer are that seeds are more easily planted directly in the compost and compost, if made from a variety of feedstuffs, provides a wider spectrum of nutrient for the plants.

Cover Crops, Used Correctly, for Even Large Farms

A wheat farmer in Montana is not going to be spreading an inch of compost on his 1,000 acres, or even soybean meal and a mulch of straw. Agriculture is a balancing act, again, not Mother Nature but not disrespecting her either. In the case of a wheat farmer, or any large scale farm, cover crops are a practical route to healthy soil.

Cover crops are plants grown specifically to maintain or improve a soil. Cover crops may occupy the ground for part or for the whole season. As they grow, their roots push through the soil to break it up and, upon their death, leave channels for air and water. Roots exude natural compounds that stimulate a a wide population of beneficial microbes and release nutrients from the soil’s rocky matrix. Leguminous cover crops garner nitrogen from the air into a form that plants can gobble up. And once dead, deliberately or with age, cover crops can maintain or increase all important soil organic matter.

Oat cover crop in one of my beds.

The devil is in the details. Killed too young, while still lush and green, a cover crop adds nothing in the way of soil organic matter (but does protect the soil surface from erosion). Tilling a cover crop into the soil, a common practice, might burn up more organic matter, by giving the ground a big burst of oxygen, than is added by the cover crop, whether the cover crop is young or old. And then there is the choice of cover crop itself for regional adaptability, for shading out weeds, or for beefing up a poor soil.

How about this? Set aside a separate area for cover cropping each year. Or set aside a separate area for cover cropping, but mow the plants one or more times through the growing season to provide mulch or feedstuff for compost. With enough land and suitable mix of cover crops, including legumes for nitrogen.

—————————————-

“Sustainability” is a buzzword these days. Nourishing the ground with nothing more than annual sprinklings of chemical fertilizer not sustainable in terms of long-term soil health and because synthetic fertilizers require fossil fuels in their making. At he other end of the scale, primitive slash and burn agriculture, where land is cleared and burned, crops planted for a few years, then the site abandoned for a new site, is sustainable. But you need enough land to be able to leave time for the soil to naturally regenerate before another slashing and burning. In our “advanced” culture, recycling organic materials back to the land is also sustainable. It’s just a matter of getting the materials back into the soil, as compost or more directly, but not to a landfill or an ethanol (gasahol) factory.

Fruit, Grain, & Vegetable

October 10, 2014/13 Comments/in Fruit, Gardening, Pruning, Vegetables/by Lee Reich

Homegrown Persimmons, Popcorn, and Brussels Sprouts, All in Abundance

It’s raining persimmons! And every morning I go out to gather drops from beneath the trees. And every afternoon. And, depending on the wind and the temperature, sometimes early evenings also.

The fruits are delicate, their soft jelly-flesh ready to burst through their thin, translucent skins. Most fruits survive the trip from branch to ground unscathed because of the close shorn, soft, thick lawn landing pad that awaits them. I pop any that burst right into my mouth or else toss them beyond the temporary, fenced-in area as a treat to my the ducks or to Sammy, my dog who has developed a taste for the fruit. (The ducks, Indian Runners, hardly fly but Sammy, if he put two and two together, could easily hop the low fence and beat me to the fruits.) Repeatedly gathering fruit through the day is needed to keep ahead of scavenging insects.

Szukis persimmons, ready to eat even from leafless branches

American persimmons grow wild throughout much of the eastern part of our country, about as far north as the Hudson Valley. Wild trees bear either female or male flowers. Males, which never bear fruit, can each sire a few females, which are the ones that do bear fruit. Puckery flavor is the main problem with wild persimmons. They can make your mouth feel like a vacuum cleaner is at work within. All American persimmons elicit that unpleasant feeling until fully soft, colored, and ripe; some elicit the feeling, in some measure, even when ripe.

Planting a named variety can spell the difference between a fruit to spit out and a fruit to swoon over. Said variety needs to be one that, besides tasting good, ripens within the growing season, and isn’t harvested until dead ripe. (Many otherwise good varieties do not have time to ripen this far north.) Szukis and Mohler do particularly well here near the northern limit for persimmon growing, Mohler beginning its ripening at the end of August, and Szukis the end of September. Both varieties ripen fruits over a long period, for a month or more.

One more asset for Mohler, Szukis, and some other varieties is that they make males superfluous. They can set fruit parthenocarpically (without pollination) and/or by pollination from their own occasional male blossoms. Most Mohler and Szukis fruits are seedless, a sign of parthenocarpy, but occasional fruits have a seed or two, indicating that some pollination took place.

Once leaves drop from these trees, fruiting is not finished. Ripe, orange fruits will cling for weeks to bare branches like Christmas ornaments, although, with time, fruits shrivel and brown, losing their visual — but not gustatory — appeal. Not bad for a tree that needs nothing in the way of pruning or pest control, eh?

Popcorn’s Not Just for the Movies

With the fruit course out of the way, let’s move on to the grain course. I’ve tried growing wheat and rice on a (very small) garden scale, and yields were paltry and sometimes difficult to get at because of topheavy plants flopping to the ground. Flopping was probably due to too much fertility and moisture. Processing either grain was a project in itself, entailing removal of the grain from the stalks and then from their husks.

The easiest grain to grow and process on a backyard scale is popcorn, which revels in my soil’s good fertility and moisture. I grow popcorn the same way as sweet corn, in “hills” (which, horticulturally speaking, are stations or clusters rather than raised mounds) with 3 to 4 plants per hill and two rows of hills in each 3 foot wide bed, with two feet from hill to hill within each row.

The only downside to growing popcorn on a small scale is the need to keep it away from sweet corn, if you grow that also. Planting sweet corn and popcorn too close to each other lets them cross-pollinate, resulting in sweet corn that is less sweet and popcorn kernels than wanly split to exhale steam rather than blow apart till they’re inside out.

Even with popcorn grown in sufficient isolation, correct moisture level (20 percent) is what makes for good popping. I wait to harvest until the ears and husks are dry on the stalks. After harvest, I peel back the husk, leaving a few layers, pull off the browned silk, then tie 3 or 4 ears together by their pulled back husks and hang the bunch from the kitchen rafters to dry.

The ears hang from the rafters all year ready for popping. When I feel like eating some popcorn, I just twist the kernels off a cob; microwavers can put the cob, intact, into their microwave ovens. I find that poppability varies through the year, probably depending on the temperature and the humidity.

If I sought maximum poppability, I could measure the moisture level by accurately weighing out a portion of kernels and drying them in a 150°F. oven overnight, then re-weighing them. But how big the kernels can puff up isn’t nearly as important to me as the fact that popcorn is an easy-to-grow, nutritious, whole grain that’s tasty and fun to eat.

The Sprouts Responded to Being Pinched

Finally, moving on to the vegetable course. A few weeks ago I wrote about sizing up the sprouts of Brussels sprouts by pinching the tips of the plants. That stops the production of the hormone auxin, which had been suppressing sprout growth further down along the stem.

Pinched Brussels sprouts plants have larger sprouts

The suppression is only temporary. As uppermost buds start to grow, they, in turn, start pumping down auxin. Those 3 or 4 upper buds now threaten to expand to become stems. At this point they can do what they will because lower buds — the sprouts — have all puffed up to good size.

A BOUNTIFUL SEASON AND “DELIGHT”-FUL VINDICATION

September 26, 2014/8 Comments/in Gardening, Planning, Soil, Vegetables/by Lee Reich

My Green Thumb, or Not?

I wish I could say that my ever-greener thumb is responsible for the baskets overflowing with tomatoes and ripe red peppers in the kitchen, and strings of fat, sweet onions hanging from garage rafters. Ripe figs hang lax from branches, a drop of honeydew in each of their “eyes” telling me they want picking. The season has been bountiful.

I can’t recall anything special that I did this season that would have boosted the harvest of so many different fruits and vegetables. The soil, as usual, got lathered with an inch deep layer of compost. Transplants and seeds got started with hand watering, then drip irrigation automatically quenched plants’ thirst from then on. I kept my usual eye out for insect or disease pests.

Sweet Italia peppers, like everything else, bore in abundance this season.

Further deflating my own gardening prowess is the fact that a lot of you readers also have experienced a season of bumper crops, right? (Not to wish ill upon your garden, but please tell me “no.”)

So let’s credit this season’s abundance on the weather. Rainfall was regular and sufficient up until August. Those periods of rain punctuated longer periods of intense sunlight in which plants no doubt reveled.

Temperatures also get credit. Very hot weather interfered with corn and pepper pollination last year; not so this year. Temperatures were neither too hot nor too cool all season long. Okra was the only vegetable complaining this year. Torrid weather is needed to keep those pods coming on. This summer, pods appeared on okra plants whenever the mercury soared, then the plants just sat, doing nothing, waiting out periods of cooler temperatures.

Good Show, Mustard

It’s time to render praise to a vegetable that has tasted and looked fresh and good all season long, every season, irrespective of the weather. That vegetable is mizuna, sometimes known as mustard cabbage or kaai ts’oi, or botanically as Brassica juncea or Brassica rapa nipponosica.

I sowed mizuna seeds along with lettuce and arugula seeds in the garden in April in a bed slated for corn planting later in June. Mizuna, lettuce, and arugula all provide greenery for early salads, enjoy cool spring weather, and are in and out of the garden quickly enough to be out of the way for a later crop such as corn. I pulled out these plants just before sowing corn — most of them. Arugula was anyway going to seed and the lettuce was soon to take a step in that direction.

Mizuna, though, was still looking fresh and green so I left it in place.

As corn stalks reached skyward, mizuna kept its fresh appearance and tenderness of spring. That corn bed is now ready for harvest and mizuna is still tender and tasty. Most kinds of mustard greens would have tough leaves and have gone to seed months ago. After the ears of corn are harvested, my plan is to dig out the corn plants, carry them off to the compost, and leave mizuna to carry on until really frigid weather turns its leaves to mush.

Mizuna flavor is mustardy, but only mildly so. Taste it and it seems to ooze vitamins and minerals, borne out by analyses showing it to be especially rich in pro-vitamin A and calcium.

Gardener’s Delight Unraveled

Did this season’s weather make for better-tasting tomatoes? Perhaps. Perhaps not. The main influences on tomato flavor are the amount of sunlight, the amount of water plants take up, probably plant nutrition, especially with respect to potassium and phosphorus, and — most importantly — the variety.

I’m happy with the taste of this season’s tomatoes but was eagerly awaiting ripening of the variety Gardener’s Delight. I grew Gardener’s Delight about 40 years ago and thought it was the best-tasting cherry tomato in the world. After not growing it for decades (other varieties got my attention), I grew it again last year, only to be disappointed in the flavor. That led me to wonder whether the apparent change in flavor was due to Fedco Seeds, the company from which I purchased the seeds, getting sloppy with their seed-saving, differing growing conditions (Wisconsin vs. New York), or whether I had become more discriminating in tasting my tomatoes.

As a test, this year I planted seeds of Gardener’s Delight from three sources: Fedco Seeds (www.fedcoseeds.com), Botanical Interests (www.botanicalinterests.com), a

Sungold, hands down the best tasting cherry tomato

nd Thompson & Morgan (www.thompson-morgan.com). The latter is a British seed company, the source of the seeds I planted 40 years ago. Last week, to a drum roll (in my head), I tasted Gardener’s Delight tomatoes from each of the three sources. They all tasted the same — and not very good. Fedco Seeds was exonerated.

Ruling out growing conditions since all my other tomato varieties taste as good as in seasons past, the verdict lies in my taste buds. Not that my taste buds themselves have become more discriminating. Instead, cherry tomato varieties have greatly improve over the past 40 years.

More specifically, the variety Sun Gold came on the scene more than 20 years ago (also introduced by Thompson & Morgan and now widely available). I think I speak for everyone in stating that Sun Gold is the best tasting cherry tomato ever. Gardener’s Delight may have been good in its day but it has been easily eclipsed by Sun Gold.

Whether the growing season is cloudy or sunny, or warm or cool (within reason), Sun Gold always offers a bounty of persimmon orange, delectable, sweet-tart tomatoes with bold flavor.

Controversial Garlic & Corn

September 19, 2014/23 Comments/in Gardening, Planning, Soil, Vegetables/by Lee Reich

When to Plant & Whether to Plant, Corn & Garlic

Into the ground goes the stinking rose. That’s garlic. As a matter of fact, by the time you read this my garlic cloves will have been in the ground for awhile, since the beginning of the month, already sending roots out into the soft earth.

Planting garlic this early is sacrilege in most garlic circles. But it may make sense.

Garlic needs a period of cool weather, with temperatures in the 40s, to develop heads. Without that cool period, a planted clove merely grows larger, without multiplying. Which is why it’s planted in fall. Spring-planted garlic might still get sufficiently chilled or needs to be artificially chilled, but yields are generally are lower than fall-planted garlic.

Lower yields could also be because the cloves, planted in spring, must put energy into growing both leaves and roots. Roots grow whenever soil temperatures are above 40 degrees F., so fall-planted cloves start growing roots immediately. And for quite a while because, with the ground cooling more slowly than the air, balmy weather lingers long in the soil in fall, especially when it’s covered with an insulating layer of wood chips, compost, straw, or other organic mulch.

My reasoning for late summer planting rather than fall planting is that the sooner the bulbs are in the ground, the more time roots have to grow before temperatures drop consistently below 40 degrees. More root growth now means more roots to fuel leaf growth in spring which, in turn, means bigger heads to harvest next summer. More root growth also means that cloves are more firmly anchored into the ground through winter, so are less likely to heave up and out of the ground as it freezes and thaws.

The caution against planting as early as I suggest is that leaves might awaken and push up through the ground in fall, only to be snuffed out by winter cold. True. But garlic is a monocotyledenous plant, so its growing point, like that of other “monocots” (such as lilies, onions, grasses, orchids, and bananas), lies beneath the ground, protected from cold. The usual recommendation for garlic planting is to plant early enough to allow time for some root growth but late enough so leaves don’t appear aboveground.

Leaves peering above ground in fall might even help spur root growth, at least once they start exporting energy. (Their initial growth is fueled by energy reserves in the planted clove.) Even if winter cold kills the leaves, they will have done some good if they begin growth soon enough. The sloppy mess of frozen leaves could, admittedly, breed unwelcome bacteria or fungi.

Biological systems are complex, and plants don’t read what I write and may not follow my reasoning. Just to check, I planted only half of my garlic bed; I’ll plant the other half in a month, the recommended planting time. Next summer I’ll know if my garlic cloves followed my reasoning.

Corn, Worth Planting

Garlic is for the future; sweet corn is for the present. Whoever it was — and there were plenty of those “whoevers” — that recommended against growing sweet corn in a small garden because it wasn’t worth the space did a disservice to gardeners. My garden isn’t all that big yet we’ve been harvesting all the sweet corn we can eat and freeze since early August and will continue to do so for much of this month.

Sweet corn can share a bed with other vegetables, lettuce here.

My vegetable garden is in 18 foot long, 3 foot wide beds, and I planted 4 beds at two week intervals from early May until the third week in June. I sowed the seeds sown in hills (clumps) to end up with 3 to 4 plants every two feet in a double row running down each bed. Planting in hills provides better pollination and resistance to wind than planting rows of single, more closely spaced plants.

Each stalk yields one or two ears, so a conservative 1.5 ears per stalk and 3 plants per hill computes to yields of 81 ears of corn from each of four beds. That’s a lot of sweet corn! And not just any sweet corn, but Golden Bantam Sweet corn, the standard of excellence in sweet corn a hundred years ago. You can’t buy ears of this variety these days. It’s the only one I grow.

Corn, densely planted, and ready for harvest

Pumping out all those delectable ears requires good growing conditions. To whit: Very fertile, well drained soil; water as needed; and little competition from weeds. I slathered the beds with an inch or more of compost in spring and all summer plants’ thirst has been daily and automatically quenched with drip irrigation.

I didn’t even have to devote those beds to only sweet corn for the whole season. Earliest plantings were preceded and are followed by quickly maturing vegetables such as lettuce, spinach, and radishes. Turnips, winter radishes, and bush beans are other possibilities to follow harvest of those first sowings of sweet corn. A row of carrots and beets was sown

Delectable Golden Bantam, a hit since 1906

up the middle of the second planting shortly after the corn emerged and is doing fine now that the corn has been harvested and those plants cleared away. I’m still trying to figure out what to plant to follow the third planting, which is just finishing up.

I also grow popcorn, but that’s another, also delectable story.

Hormones Get Pumping

September 12, 2014/5 Comments/in Books, Fruit, Gardening, Vegetables/by Lee Reich

More Brussels Sprouts, Cabbages, & Pears with Hormones

It’s time to get the hormones pumping. No, not by me embarking on some testosterone-fueled, garden-related feat of strength or endurance. Not even my own hormones, but the ones in my plants, more specifically my brussels sprouts plants. And actually, quashing the action of one hormone so that other hormones can come to the fore.

Let me explain: Brussels sprouts are not only a member of the cabbage family but are the same genus and species as cabbage, as are broccoli, cauliflower, kohlrabi, and kale. Differences in these plants lie in the way growth of the stems and leaves are expressed. Cabbage has a single stem that’s been telescoped down to very short internodes, resulting in a tight head of overlapping leaves. With kale, internodes along the stem are further apart, allowing each leaf to unfold fully on its own. They also look different from those of cabbage.

In every plant, a shoot bud develops in the upper part of the crotch where a leaf joins a stem. Most brussels sprouts buds each start to develop enough to form a small, cabbage like head. But I — and probably you also — want large brussels sprouts sprouts (and more of them, so I also want tall brussels sprouts plants on which to attach the sprouts).

Pinching makes Brussels Sprouts sprouts bigger

The sprouts are retarded somewhat in their development by a hormone called auxin. Auxin is one of many plant hormones coursing about within leaves, fruits, shoots, and roots, their effect dependent on such variables as plant part, plant age, and what other hormones they are reacting with. One place of auxin synthesis is in the tips of stems, and their effect is to suppress growth of buds down along the stem, with more suppression the closer a bud is to the tip of the stem. I just looked at my brussels sprouts plants; yes, the largest sprouts are those nearest ground level. It’s still too early to harvest and too many of the upper sprouts, at present, are too small to be worth picking.

Suppressing auxin production in the tip of the stem releases their hold on the buds — that is, the sprouts — along the stem, so they can grow larger. Suppressing auxin production is simple, requiring only two fingers: Just snap off the tip of the stem. No tip, no auxin production, for a while, at least. The time to do this “operation” is the beginning of September. Done too soon, and a developing sprout might grow so bold as to grow out into, at worst, shoots or, less worse, loose heads. Plus, earlier in the season, I want to keep the stem elongating to provide real estate along which to hang more sprouts.

A Three-Headed Cabbage!

As I wrote, every plant develops buds in its leaf axils, and in every plant growth of those buds is mediated, in part, by auxin. Harvest the main head of broccoli and side shoots start to grow for eventual harvest.

Even tight heads of cabbage have those buds and they also respond to auxin’s influence. I used to plant cabbage in the spring for harvest in summer. Rather than pulling out the spent cabbage plants, as is usually done, I would leave the cut stump with a few bottom leaves for nourishment. Harvesting the cabbage dramatically removes the tip of the stem, which was buried within the head.

Cabbage plants left after harvest develop multiple heads

Cabbage left after harvest = multiple heads

Within a couple of weeks, new sprouts would develop in the crotches where leaves were or had been. In the ideal world, I’d get one to three new cabbage heads from each plant, ready for autumn harvest. A certain amount of art was needed to get it right. Depending on growing conditions and the number of new heads I allowed to develop, they might end up too small or too loose-leaved.

I’ve abandoned that chancy cabbage habit and now do a second sowing of cabbage in early June for a reliable autumn harvest of firm heads.

Pears — More, Please

I fiddled around with hormones earlier this season also, with longer term goals in mind. Auxin keeps the tip of a stem or the upper portions of a plant growing most vigorously. Vigorous growth, though, is at odds with making fruit. After all, both require a lot of a plant’s energy, so the plant has to partition the energy efficiently between growing and fruiting.

Pear trees are famous for growing vigorous shoots skyward. Yes, shoot growth is needed on which to hang fruit and for adequate leaves for photosynthesis. But enough is enough. Rather than pinch out shoot tips, which would likely just pass on the vigor to nearby lower buds, I bent ranches down and held them there with string. Changing stem orientation from vertical to at or near horizontal quells auxin production, slows growth, and promotes the formation of fruit buds along the stem. (Fruit buds form the year before flowers open.)

Fruits now dangle from some of the stems that I pulled down a year ago last spring. The response can take more than a year as energy reserves are redistributed within the stem. Response also depends on a tree’s inherent vigor, growing conditions for the season, the pear variety, the degree of stem bending, and other knowns and unknowns. It’s takes a mix of science, art, and experience, and that’s what makes gardening so interesting for me.

End of Summer? Enter the Fall Garden.

September 5, 2014/2 Comments/in Gardening, Planning, Vegetables/by Lee Reich

Fading Summer Brings in Fall Greens, and Hollyhocks for Cheer

There’s a flurry of seed sowing and setting out of transplants going on here. Am I deluded that it’s springtime? No. Autumn is around the corner and there are vegetables to be planted.

For many gardeners, summer’s end and the garden’s end are one and the same. But planning for and planting an autumn vegetable garden bypasses the funereal look of waning tomatoes, peppers, cucumbers, and other vegetables that thrive only with summer heat and long days of sunshine, and puts plenty of fresh vegetables on the table. Having an autumn vegetable garden is like having a whole new garden, one that gradually fades in, like a developing photograph, as summer vegetables fade out.

Autumn vegetables come to the fore as tomatoes fade away

Which is why today I tucked two dozen endive transplants into a double row of holes spaced fifteen inches apart in a three-foot-wide bed. And which is why, in a different bed two weeks ago, I sowed a row of Watermelon winter radishes (the resemblance to watermelon only in the color of their innards), a row of turnips, and a row of Chinese cabbage. Also, why back in March, seeds of Brussels sprouts were sown, the seedlings of which were transplanted to yet another bed last May.

Not that the time has passed for planting any autumn vegetables; plenty of vegetables that enjoy the cool moistness of autumn are still to be sown. This week, I plant to sow lettuce, spring radishes, arugula, mustard, and spinach.

Edamame Out, Endive In

The question might arise as to where to plant all these autumn vegetables when the garden is already overflowing with summer vegetables. Overflowing, really?
I planted the endive transplants in a bed that I had just cleared of edamame plants; edamame bear over a period of a couple of weeks and then they’re done, which they were. Likewise, a whole bed of onions and a first planting of corn are finishing up, freeing up space for planting. Even the bed from the second planting of corn will be freed up the end of August.

Endive transplants go where edamame once grew

Harvest of bush beans does not halt as abruptly as that of corn, onions, or edamame. Nonetheless, the bean harvest does begin to taper down after two or three weeks, so out went the first planting of bush beans a couple of weeks ago. A second planting, sown in a different bed three weeks after the first planting, took up the slack, and today I’m pulling even those plants out of the ground. Pole bean plants will keep green beans on our plates until frosty weather, which it what it takes to put a stop those plants.

Can’t Help But Smile With Hollyhocks

My garden isn’t only about food. I’m also sowing some flower seeds now, not to blossom in autumn but to get a jump on next spring.
This past spring I sowed seeds of Apricot-Peach Parfait hollyhocks (from https://www.reneesgarden.com). Right now, the plants’ seven-foot-high spires are studded along their length with frilly blossoms in delicious shades of apricot and rosy-peach. I want more.

Spires of Apricot-Peach Parfait hollyhocks add a smile to the garden.

Hollyhock self-seeds so future population growth could be left to the vagaries of nature and weather. But overly diligent weeding or mulching might quash newcomers, so I’m going to sow more seeds. Hollyhock is a biennial or short-lived perennial so that self-seeding habit is welcome.

As either a short-lived perennial or biennial, hollyhocks tend to grow just leaves their first year and flower their second year — then die if they behave like a biennial, or go on to flower for more years if they are perennial. I was able to get flowers this season from spring-sown seeds because I planted the seed early and the seedlings spent their first few weeks of growth in the greenhouse. (Through breeding, some varieties of hollyhock behave as annuals, and bloom reliably their first year — but not as seven-foot-high spires.)

Planting the seed in late summer guarantees that the plants will bloom next year, and earlier than spring-sown plants. Cool weather of late fall and late winter helps trigger the flowering response.

Delphinium is another flower to sow this week. In addition to the advantages of enjoying spires of blue flowers earlier and more reliably next summer, delphinium seeds sprout more reliably if fresh, which they are more likely to be in autumn than the following spring. Chilling the dry seed — some sources suggest stratification, that is, chilling the moist seed — for a week or so also is said to help wake it up.

Once seedlings of hollyhocks and delphiniums get going, they’ll need special accommodations to get through winter. After all, they’ll still be tender, baby plants when the weather turns frigid. The goal is to keep them alive and growing slowly going into winter. I’ll either tuck the pots close together in the cold frame or in the slightly warmer large window in my barely heated basement.

GOOD FUNGI AND BAD INSECTS

August 21, 2014/8 Comments/in Gardening, Pests, Soil, Vegetables/by Lee Reich

Fungi I Like and Bean & Japanese Beetles (Don’t Like)

Where once scorned or appreciated only after being sautéed in butter, fungi have finally come into their own. If you’re among those who isn’t awed by fungi except when they’re sautéed, swallow this: each gram of soil (the weight of a paper clip) might house over a million fungi, or anywhere from 10 to 100 pounds of them in the top 6 inches of a 1000 square feet of soil. And most of what they do — for plants and soil, forget about your taste buds for now — is beneficial.

I recently heard of a project using fungi as a building material. On exhibit at the Metropolitan Museum of Art’s PS1 in New York City is Hy-Fi, a cylindrical tower built our of bricks made from fungi that have been fed cornstalks, the fungi’s fine, thread-like hyphae growing to create dense bricks. An organically grown building! Among the benefits touted were that a building made of fungi could be recycled.

I’m not so sure that a building that can be recycled is a good thing, but one statement by the architect did raise my hackles: that the building could be made of waste materials, such as cornstalks. The same argument could be or has been used for ethanol production, which could be made from the same waste material.

Corn stalks might be waste material in the sense that we don’t eat them, perhaps not even always feed them to animals. But corn stalks, wheat straw, and other so-called “waste materials,” as the architect perhaps inadvertently pointed out, are a gourmet delight for fungi. Also good food for bacteria (3 million to 500 million per gram of soil), actinomycetes (1 million to 20 million per gram of soil), as well as protozoa, nematodes, and other soil creatures. And don’t forget about earthworms (2 to 22 pounds per 1000 square feet of ground). There’s a lot of hungry creatures down there.

So these materials are not waste; they are food for soil life. They are what put the “organic” in organic gardening and farming. (They are “organic” in the sense that they were once living, and that they contain carbon compounds, mostly combined with hydrogen and oxygen.) They confer a range of physical, nutritional, and biological benefits to soil, plants, and, hence the animals, including humans, that feed on them. Depriving the soil of these organic materials is what led, in part, to the dust bowls of the 1930s.

Corn stalks as well as other organic materials too often considered as waste should be returned to the soil, either directly or after being first run through a compost pile. One measure of soil quality is the amount of organic material it contains.

Waiting Out Japanese Beetles

Japanese beetles have not come into their own; they have never been and continue to NOT be appreciated. The swarmed in a few weeks ago to make lace of the foliage of a whole host of plants. Grapes are among their favorites, evident by merely looking out on the landscape and picking out the hole-y grape leaves. (The leaf veins typically remain intact.) Although roses are also a reputed favorite, the beetles left mine unscathed.

Kiwi foliage made lacy by Japanese beetles

Most interesting is the beetle’s effect on my hardy kiwifruits, specifically the super-hardy sorts (Actinidia kolomikta). I have four plants, 3 females — Krupnoplodnaya, Aromatanya, and Sentayabraskaya — and one male. Of all those plants, only the Sentayabraskaya plant was attractive to the Japanese beetles, dramatically so. Looking up, I can see sky through almost every leaf.

Japanese beetles are hard to keep in check. For a few plants, hand picking into a can of soapy water (the soap so they don’t just fly out after a quick bath) is effective. The biological insecticide milky spore disease, applied to lawns to kill the grub stage in the soil, is sometimes effective, especially in more southerly locations. Of course, beetles emerging from the soil in summer can fly, so milky spore is useless unless done on a neighborhood scale. Neem is a relatively benign repellant and insecticide that’s somewhat effective sometimes; it would require too much spraying, especially for something with such an iffy effect.

So I just wait the beetles out. Plants can tolerate a certain amount of damage and the beetles typically wave goodbye to go burrow into the soil and lay eggs sometime in August. The wait was especially short this year, with most of the beetles departing by the third week in July. Thank you guys, and gals.

And Where Did Mexican Bean Beetles Go?

A Mexican bean beetle threesome

Other pests also come and go. Mexican bean beetles, mentioned last week, still are keeping to themselves, wherever that might be but not in my garden. Tomato hornworms, which are large caterpillars with voracious
appetites, stripping leaves from tomato plants in the matter of hours, turned up in a friend’s garden. Fortunately, piggybacking those beetles were what looked like grains of rice. They’re actually cocoons of a braconid wasp, which will kill the hornworm. Leaving parasitized beetles alone lets the parasite live to attack more hornworms.

Rice-like granules attached to tomato hornworm are parasites

Parasite attacks tomato hornworm; winner: parasite.

Also worth ignoring are the pimples that have been appearing on leaves of many pin oaks. Those pimples — hemispheres about 1/2” across — are galls. Plant galls are abnormal growth made in response to an irritant such as a bacteria, a fungus, or, most commonly, an insect. A few galls here and there rarely do a plant harm.

Those oak leaf galls are pocking almost all the leaves on my pin oak. Still, I’ll ignore them or admire them; they sort of liven up the look of the tree. It’s too late, anyway, to do anything about them.

Rei-King, an Ancient Exercise?

Among the many benefits of gardening is the opportunity it offers for enjoyable, productive exercise in the great outdoors. And now we can add an exercise called rei-king to boot camp, pilates, zumba, kick boxing, cardiofunk, and other ways modern humans build and maintain sleek, fit bodies. Or so I told my wife, Deb.

Rei-King by Deborah as Sammy looks on.

As with some of those other exercise routines, equipment is needed, simple equipment in the case of rei-king. Basically, the equipment is a pole, perpendicular to and at the end of which is a length of wood or metal, attached in its middle to the pole. From the lower side of the length of wood or metal are teeth, each a couple of inches apart and a couple of inches long.

Now for the exercise. You lift the pole just enough to bring the head off the ground, reach forward, and pull it towards you. For balanced exercise, it’s advised to occasionally switch which arm is most forward.

Resistance is the way to build up muscle and endurance. That resistance comes in the form of friction from material lying on the ground. This time of year, that material might conveniently be mown long grass or hay.

And Sie-Thing

I sometimes practice rei-king; more often I choose another exercise that complements Deb’s rei-king. I practice sie-thing (pronounced “sigh-thing”).

Like rei-king, sie-thing entails using one piece of equipment, a sie. The sie also has a single pole, in this case with two handles attached, one at the upper end and one about halfway down. A metal weight is attached at the bottom of the sie. The metal is a couple of feet long, curved, and sharpened on its inside edge. Muscle tone and strength is created by putting the left hand on the upper handle, the right hand on the lower handle, flexing the spine to the right and then unwinding it to the left while trailing the metal weight just above ground level.

Here I practice the ancient art of Sie-Thing.

Again, sei-thing can be made more rigorous, in this case by passing the sharp metal through tall grass or meadow plants. The taller the plants, the denser the plants, and the older plants, the more the resistance.

A side benefit of all this sie-thing is that grass or meadow plants get mown during the exercise. The fallen material drops right in place, providing an opportunity — for me or, more usually, Deb — to then practice rei-king.

By the way, either exercise is most enjoyable early in the morning. At that time, plants are turgid so the sharpened metal of the sie pops plant cells as it is drawn along. And the fallen plants, best for rei-king after lying on the ground a day or two to wilt, cling together nicely when heavy with dew. The cool morning air is also conducive to exercise.

Basil for Winter?

Many years ago I grew the few varieties of basil that were available and then wrote about them. My conclusion, at the time, was that taste differences between the varieties were minor, so the choice of what to grow should perhaps be on the fun of saying their names, which put Genova Profumatissima, Syracusa, and Fino Verde Compatto at the top of the list. What fun to wave my arms and speak their names!

Or, a variety could be chosen for the size or color of its leaf, whether for decoration or culinary use. “Spicy Globe basil, planted close together, makes soft, green mounds resembling a miniature boxwood hedge,” I wrote. Now we have yet another decorative form: Bonsai Basil.

To create a bonsai basil, a variety such as Spicy Globe — perfect, with its diminutive, closely spaced leaves — is grafted onto a special rootstock. That rootstock is another variety of basil, one chosen, in perfect world, to impart to the grafted plant vigor, disease resistance, and hardiness. Periodically shearing such a plant keeps up appearances even as it provides basil for flavoring. Over time, the trunk even turn woody.

Even better, carry on the fun and the flavor through winter. Basil is perennial in the tropics but generally does not fare well in the cool, dry air, and relatively dark conditions of a northern home in winter. All of which calls out for a vigorous, disease-resistant, hardy plant. A grafted basil. Grafted basil, even more than grafted tomatoes, are very much the new kid on the (grafted) block.

A few weeks ago I was given a couple of grafted bonsai basil plants and I’m planning to grow them as perennials. It turns out that my plants are on a rootstock called Nufar which is resistant to fusarium disease. My soil doesn’t harbor basil fusarium disease, so that rootstock is of no benefit in that department. Perhaps it will help get the plant through the long, dark winter indoors anyway.

New rootstocks that could impart vigor and hardiness to help get a bonsai basil through winter — indoors, of course, around here — are on the horizon.

————————————————-

Ah, fusarium. Reminds me of last week’s patting myself on my back about my conquest of pea fusarium, which has plagued me for years. Well, between last week and this week, fusarium has again reared its ugly head and the vines have yellowed. I did get a decent crop, however. Looks like management rather than conquest will be the key to annual harvests of peas.
