COMPOST, FERTILITY, & SUSTAINABILITY

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.

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.”

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.N veg. garden, beds Oct '14

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.

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. 

FLOWERS FOR THE VEGGIE GARDEN

Zinnias In and Colchicum Outside

And the winner is  . . . Every year boxes of plants arrive at my doorstep, sent by nurseries and seed companies hoping to wow me with their products which I will then praise and induce you all to purchase. Most of the plants turn out to be ho-hum, perhaps new but not necessarily better than what’s been around for decades. Not so this season, for a charming yellow flower that’s been blooming nonstop all summer long and offers no indication as yet of expiring.Yellow blossoms of Zahara zinnia

That plant is  . . . unfortunately I lost the label so have been sleuthing for days now to give this winning plant a name. It looks much like a zinnia, a single flowered zinnia, that is, one with a single row of petals. The plants are compact, a little more that a foot high and wide, and — very un-zinnia-like — show no signs of powdery mildew.

My first guess for the plant was creeping zinnia, which actually can be one of two different plants. The first is a true zinnia, Zinnia angustifolia, and the second is not really a zinnia; it’s Sanvitalia procumbens. After getting out my botany books (books!) and magnifying glass and staring at the peduncle, receptacle, and disk and ray flowers of a flower from my plant and comparing it with written descriptions, I was still scratching my head to give my plant a name.

In frustration, I went to the garage to my “miscellaneous” bucket into which I sometimes toss plant labels that I might need to reference again at a later date. Digging down deep amongst all shapes and sizes of labels, I came upon one printed “Zahara Yellow Improved Zinnia.” Back inside, on the web, comparing descriptions and photos verified that — yes — that’s the plant.

The botanical name listed for Zahara zinnias, which also come in other colors, is Zinnia Marylandica.  That species name looks and is fake. Zaharas are interspecies hybrids, with some creeping zinnia (the Z. angustifolia c.z.) in their blood. So my guess at their being creeping zinnia was not far off.

Looking over at my conventional zinnias (Zinnia elegans) for comparison, they appear gawky witI their large flowers, both new and faded ones, prominently perched atop long stalks. Their many petalled blossoms look too full of themselves. Zahara buries its spent blossoms out of sight amongst new flowers and foliage of the compact plants.

Next year, I’m planting Zahara Yellow Improved Zinnias again.

A Vegetable Factory Functionally, But Not Visually

Those Zahara zinnias, planted along the main path of the vegetable garden joining arbored gates at either end, create two golden ribbons to draw you along the path. As I walk the path and glance left, north, I see, just outside the garden fence, another ribbon, this one a broad brush stroke of purple with not a hint of green. (More on that later.)

Yellow zinnias line the main path in the vegetable garden

Yellow zinnias line the main path in the vegetable garden

A vegetable garden need not be a vegetable factory. Too many look as if dropped from the sky, plopped down in the middle or far corner of lawn and enclosed with a strictly functional fence. Why not make the vegetable garden pretty and cozy it up near the house? Beds paint a two-dimensional design on the ground. A nice fence helps; even better if it integrates with the style of the home.

Vegetable gardens often look stark because of the abrupt transition between the vertical fence and adjacent, horizontal lawn. Decades ago, I regularly rototilled around the outside of my fence to keep weeds away from the fence line. I decided that was wasted space, so planted it with shrubs, flowers, and vegetables that didn’t need fencing. It was a good decision, softening the transition from garden to lawn.

So gussy up your vegetable garden with ornamental plants inside and out, with decorative fencing and arbors, perhaps an herb-lined path drawing you within, or perhaps with a bench, bird bath, or gazing globe as a draw.

And A Stripe of Purple to Gussy Up the North

That purple brush stroke north of my vegetable garden are the petals of autumn crocus, Colchicum autumnale. In contrast to the Zahara zinnias, autumn crocus has been cultivated hundreds of years, and my plants are run-of-the-mill species rather than any hifalutin variety.

Purple autumn crocuses, in a row

Purple autumn crocuses, in a row

Like Zahara zinnias, autumn crocus has nomenclature issues. To whit, it is not a crocus. Further complicating things, there are true crocuses that bloom in autumn, sometimes called autumn-blooming crocuses, among them the saffron crocus, Crocus sativa. Colchicum autumn crocus, my purple brush-stroke, is poisonous.

The purple of my autumn crocuses is so bold because leaves don’t accompany the flowers (again, in contrast to autumn-flowering crocuses, whose leaves appear with the flowers). Autumn crocus leaves are big and bold, appearing in spring and looking something like ramps, the edible wild onion species. In Europe, where both autumn crocus and a ramp-like relative, grow, people have been poisoned for mistaking one plant for the other.

But toxicity isn’t what keeps more people from planting autumn crocus. Daffodils, after all, also are toxic. The problem is timing: Autumn crocus bulbs are ready for planting in late summer, before daffodils, tulips, and other fall planted bulbs are ready. It’s hard for nurseries to get people excited about yet another bulb planting season, and only for this single species. If not planted soon enough, autumn crocus bulbs grow, even without soil. The bulbs multiply quickly and when I divided and replanted them last summer, I kept a few out, three of which now sit naked in a bowl on the dining table, blooming.

Fruit, Grain, & Vegetable

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.Szukis persimmons in hand

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.Popcorn ready for harvest

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

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.

HOW GREEN, OR NOT, IS MY THUMB?

Apples a Bust, Pears a Success, Gooseberries a Bust, etc.

Early autumn is a good time for me to find a sunny spot on the terrace with a comfortable chair, pluck a bunch of grapes from the arbor overhead, and ponder the fruits of this year’s labors. And I mean “fruits,” literally: what were my successes, what were my failures, and what do future seasons hold?

In good years, my apples are very, very good; Hudson's Golden Gem here.

In good years, my apples are very, very good; Hudson’s Golden Gem here.

To many people, to too many people, “fruit” means apples, the equivalence having deep roots since pomum is Latin for both apple and fruit. My apple crop this year, whether measured in pounds or number of fruits, is zero. Among my excuses are the wrong rootstock for the site, trees still recovering from last year’s onslaught of 17-year cicada egg-laying, apples’ pest problems making them among the most difficult fruits to grow east of the Rocky Mountains, and my low-lying valley location and surrounding forests further exacerbating pest problems.

Still, the rich flavor of the apples — when I do get some — keeps me trying. Next year I’m replanting with five new trees: Hudson’s Golden Gem, Macoun, Ashmead’s Kernel, Pitmaston Pineapple, and Liberty, all on Geneva 30 rootstocks. This year, I welcomed the time not needed in caring for the trees.

Pears did surprisingly well considering the extensive cicada damage they also endured. But pears always do well, especially the Asian pears. The challenge with European pears is ripening them to perfection. They need to be picked before they are ripe, chilled for a couple of weeks if they are an early maturing variety, then ripened in a cool room. As soon as the first fruits drop, I keep an eye out for a slight change in skin color for those fruits still hanging from branches, then take them if they separate with an easy snap when lifted and twisted from the branch.

Despite being relatively easy to grow, pears are underappreciated as  garden fruit — these days, at least. One-hundred and fifty years ago, you might have perused 70 varieties in a nursery catalog; a hundred years ago, perhaps 30 varieties; in today’s catalogs, I count a dozen or so varieties. Not all my two dozen or so varieties are bearing yet. So far, the best of the lot are the buttery sweet Magness and spicy Seckel.

And More Failures

But let me get back to my failures; get them out of the way. Hardy kiwifruits, both Actinidia arguta and A. kolomikta had uncharacteristically light crops. The same goes for pawpaws, whose branches have, except for this fall, every year been weighted down with a heavy load of fruit, some branches even breaking. It’s most convenient to point my finger at the weather, the winter cold, for barren kiwi vines and pawpaw trees. Not that it was as cold as many past winters, but it did stay cold for longer periods.

The gooseberry crop looked very promising until late June, which is when my chickens discovered them (or remembered where they were). Gooseberries are usually very reliable so I’m optimistic about the future of eating berries from the two dozen or so dessert varieties I grow. I downsized my flock from seven to three chickens (and added two ducks), and plan to erect temporary fencing during the few weeks that the berries ripen in future years.

Big crops presented themselves, as usual, on various mulberry varieties and gumi. Birds swooped in to gobble them up. Last year, with all the cicadas to feed on, birds ignored both these fruits. Geraldi Dwarf mulberry grows only a few feet high so I’ll throw a net over it next year and let birds enjoy the other mulberry varieties, if they so choose.

The Very Sweet Taste of Success(es)

Enough talk about failures. On to successes . . . blueberries, my favorite and most reliable fruit, bore in abundance, as always. Sixteen bushes; about 150 quarts. Mmmmm.

Bagged grapes next to a bunch of grapes that weren't bagged

Bagged grapes next to a bunch of grapes that weren’t bagged

Rain earlier in the season threatened grapes with disease. I enclosed about 75 bunches in white bakery bags, stapled shut, to fend off bees and wasps, diseases, and birds. The crop was in such abundance that harvest has been aplenty even from unbagged bunches. Actually, too “aplenty” from the variety Swenson’s Red, causing individual berries in bunches to ripen unevenly. Next year, I’ll prune more severely, sacrificing total yield while increasing quality and even ripening of fruits that remain.

Once unbagged grapes of a given variety have been harvested and eaten, we move on to the bagged grapes of that variety. Peeling back the white paper has generally revealed bunches that look perfect and taste delectable. Particularly tasty this year have been Glenora Seedless, Somerset Seedless, Mars, Swenson’s White, and Brianna.

Szukis American persimmon ripe on branches

Szukis American persimmon ripe on branches

And finally, another of my no-fail, no-spray, no-prune fruits: American persimmon, specifically the varieties Mohler and Szukis. Mohler has been ripening for about a month, dropping a dozen or so fruits daily, which I pick up from the ground.  My ducks are especially fond of these fruits, and waddle, staring longingly within, around the outside perimeter of the low, temporary fence that keeps them at bay. (They do get to eat fruits that drop beyond the fence.)

The soft fruits taste like dried apricots that have been plumped in water, dipped in honey, and given a dash of spice. Mohler and Szukis are almost totally lacking in the puckery astringency common to many American persimmons. To remove any last traces of astringency, I subject fruits to a treatment used in Japan with Asian persimmons: alcohol. Freshly harvest fruits go into a bowl with a tablespoon of rye (locally made Coppersea Raw Rye), covered, for a day. The alcohol finishes ripening the fruits, keeps fruit flies at bay, and adds a nice punch to the flavor.

Grow Fruit, Many Kinds!

Too many people shy away from growing fruits because they are perceived as too difficult to grow. They can be; or not. Success comes from choosing the right fruits to grow, looking beyond apples, peaches, cherries, and the other usual fare. Success also comes from growing a wide variety fruits. (All this is covered in my newest book, Grow Fruit Naturally.) This year’s apple and gooseberry failures are hardly noticed with the abundance of blueberries, persimmons, and pears. And did I mention European black currants, red currants, and strawberries?

A BOUNTIFUL SEASON AND “DELIGHT”-FUL VINDICATION

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.

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 kept bearing all season long.

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

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

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. Garlic cloves planted 4 inches apart in a furrow.

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.

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

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

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

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.

Fruiting pear branchPear 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. 

GOURMET COMPOST WORKSHOP

Compost Workshop, 09.13.14

End of Summer? Enter the Fall Garden.

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.

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.

WESTWARD HO, FOR FRUIT MEETINGS AND EATINGS

Fruit Nuts, Including Me, Nurseries, & Wild Blueberries

Are there organizations for people who make and eat cheese; build and ride motorcycles; write and read books; grow and savor fruits? All I know is that the answer to the existence of the last-named organization is a rowsing “yes!” I know because I recently returned from Oregon, where I converged with other fruit nuts  for the annual meeting of North American Fruit Explorers (www.nafex.org, and nuts, incidentally, are also covered under the organization’s umbrella).

No need to don a pith helmet and traipse off to Borneo to be a fruit explorer. Not that you couldn’t, and be one. No, this fun meeting brought together everyone from backyard growers with a few fruit plants to AN 88-year-old guy who grows over 3,000 varieties of apples. Fruits represented ranged from apples and pears to pawpaws and persimmons and, even more rare, haskaps and gumis. These people, we, realize that there’s a lot more to enjoy in the world of nature’s desserts — fruits, that is — than what you see on display in the supermarket, even farmers’ market.

What appeared to be a roomful of normal people was actually a roomful of fruit nuts, among which I count myself. NAFEX members are as varied as the fruits they grow, with all ages, genders, home towns, and “real jobs” represented. Members can share their trials, tribulations, and rewards of fruit growing (the title of my lecture there), ask questions, and exchange plants in their quarterly publication.

Each year’s annual meeting is at a “fruitful” location. Last week’s meeting took in tours of the USDA germplasm repository, which houses the USDA collection of pears, gooseberries, currants, and bramble fruits, and of research centers on hazelnuts and brambles. All accompanied, of course, by tastings. If you love fruit, grow some . . . and join NAFEX.

Branching Off to Pakistani Mulberries, Delectable Crabs, and More

I branched off (pardon the pun) from the group to visit a few nurseries. First stop was Whitman Farms (www.whitmanfarms.com), at which I made a beeline to Lucille Whitman’s black mulberry (Morus nigra) tree, an offshoot of which I’ve grown for many years. I grow it in a pot because it’s a subtropical species, not cold-hardy here. It’s worth the effort because it is among the most delectable of fruits. It’s hard to imagine that such a small berry can pack such a wallop of rich, sweet-tart flavor, much better than the wild mulberries around here. Lucille also grows a slew of gooseberry and currant varieties, another group of fruits that worthy of wider attention.

From there it was on to Burnt Ridge Nursery (www.burntridgenursery.com), worth visiting also for its panoramic view of the Cascade Mountains, including Mount Saint Helens. I soon realized, driving down the gravel nursery road, that we were passing through a virtual Garden of Eatin’, with apples and pear trees,  grapes, and hardy kiwi vines. The forest of large trees turned out to be a nursery owner Michael Dolan’s extensive collection of chestnuts. It was too early in the season to taste any chestnuts but I did get to taste his Black Pakistani mulberry, which had a chewy texture and perhaps even richer flavor than black mulberry. (Black Pakistani is a variety of M. alba, white mulberry.) Another plus for Black Pakistani is that its fruit is two or more inches long. (Lucille Whitman also sells Black Pakistani. Note to myself: Get a Black Pakistani tree to grow in a pot, like a fig.)

Finally, I motored along with Sam Benowitz north to Washington state, to his nursery, Raintree Nursery (www.raintreenursery.com). We were greeted at the nursery entrance by espaliered apple trees, then plum trees whose branches bowed

low from their load of fruit. A Centennial crabapple tree splayed out its small but ripe fruits, which were delicious, especially for a summer apple. Another note to myself: Purchase or make a Centennial crabapple. Pots of lingonberries were lush with their shiny evergreen leaves, the size of mouse ears; persimmons leaves hung languidly from the trees’ branches; and hardy kiwifruit brightened up the scene with silvery variegation, blushed with pink. Alas, these fruits were not yet ripe so for the time being provided only eye candy.

They Call Them Huckleberries

Fruit nuts are a friendly fraternity, ready to share experiences and fruit. Blueberries are among my favorite fruits, and my newfound, northwestern friends were anxious to introduce me to some western blueberry species. First was red huckleberry (V. parvifolium). Not to be an ingrate, but . . . yuk! A very small, very tart, red blueberry. Perhaps the red color threw me off. Next came evergreen huckleberry (V. ovatum), much tastier, and evergreen, but still not holding a candle to our eastern blueberry species.

Finally, though, I had a taste of mountain huckleberry (V. membranaceum). Delicious. Different but as good as our east coast species.

I was given some leafy stems of mountain huckleberry packed for travel with their bases in water tubes and their leaves wrapped in moist tissue. As soon as I got

home I stripped all but the upper two leaves from the stems and inserted their bases into the mix of moist peat and perlite in my makeshift propagator. The propagator sits on the north side of my house, its clear plastic cover maintaining sufficient humidity while letting in sufficient light until the cuttings root — I hope. Blueberry species are not particularly easy to root, although one of the main ingredients needed is patience. I’ll also sow seeds of the few fruits I brought home.

In a few years, my memories of last week’s journey may also live on in my taste buds.
