SUNNY DAYS & YOGA, BUT TOMATOES?
Springtown Farmden Health Spa
In the past, I have written of rei-king and sie-thing as two of the many healthful exercises offered here at Springtown Farmden Health Spa. We now have a new offering at the spa: garden yoga or, more catchy, gardoga or yōgdening. I like the last one best.
Yōgdening grew out of my respect for the soil, my desire to maintain and foster a healthy balance of life below ground. A healthy population of bacteria, fungi, worms, actinomycetes and other below-ground dwellers translates to healthy plants above ground. Those beneficial creatures need to breathe, which is why most gardeners and farmers till their soil. To aerate it.
Yogdening, for health and weedlessness
But tilling a soil also burns up valuable organic matter. This organic matter feeds soil organisms and, in turn, plants, makes nutrients already in the ground more accessible to plants, helps hold moisture for plants, and helps aerate the soil.
I avoid the need to till my soil for aeration by almost never walking, rolling a wheel barrow, or allowing any other traffic where plants are growing. Plants in fields and forest grow well despite never being tilled except what earthworms and other small animals manage to do. (No small amount: Charles Darwin computed that earthworms completely turn over the upper six inches of a pasture soil every 10 to 20 years — in England, at least.)
Getting back to yōgdening . . . Weeds are making inroads into certain parts of my gardens. Not my vegetable gardens, the 3-foot-wide plant beds of which I keep well weeded with my feet firmly planted in the 18-inch-wide paths bordering the beds. But the only way I can reach into some other planted areas, a bed of various flowers sprawling beneath some Asian pear espaliers, for example, is by stepping into them. To minimize foot traffic, after stepping into a planted area, I try to keep my foot anchored in place, from which I pull every weed I can reach.
As you might imagine, reaching every weed possible with feet planted in one place calls for all sorts of contortions and stretches forwards, backwards, and sideways involving my legs, trunk, shoulders, arms, and neck. My guess is that after a half-hour of weeding, I’ve run through a close approximation of Utthia Trikonāsana (Triangle Pose), Vīrabhadrāsana (Warrior Pose), and Uttānāsana (Standing Forward Fold Pose), to name a few classic yoga poses — and cleared away weeds!
Weeding (or, perhaps, I should write “we-ding,” another spa offering) is especially satisfying this time of year. Dry weather has slowed sprouting of new weeds so cleared areas remain clear.
Brown Rot Not (Too Much)
Dry weather is also good for fruit ripening. That is, ripening rather than rotting. As sweetness develops in ripening fruits, they become more susceptible to rotting. Fungi, like humans, can make quicker use of simple sugars than more complex carbohydrates, such as a are found in unripe fruits. Fruits with thin skins are especially susceptible to attack from fungi.
For a variety of reasons, known and unknown, this has been a good year for plums. In past years, late frosts in spring have snuffed out blossoms or plum curculio has caused many, if not all, plumlets to rain to the ground. This year, blossom buds were unscathed from winter cold or spring frosts, curculios were kept at bay by my spraying Surround, a commercial product that is nothing more than kaolin clay.
Shiro plum
Current dry weather should also limit plums’ other nemesis: brown rot, a fungal disease that turns ripening fruit gray and fuzzy and then, at the end of the season, into dark brown, shriveled mummies. (Of course, beautiful clear days are often followed by clear nights during which water, in the form of dew, condenses on fruits and leaves.) The mummies hang from the branches, along with cankers on branches, spread spores and infection the following year. Fallen mummies are also a source of the following season’s infection.
Brown rot gets to work early in the season, around blossom time, and then later in the season, as fruits are ripening, which is now, for my Shiro plums. Early in the season, I added sulfur, a naturally mined mineral whose use as a fungicide goes back to the ancient Greeks, to the mix when I was spraying Surround.
Supplementing that spraying was cleaning up hanging and fallen mummies at the end of the season, and promoting drying of branches and fruits with pruning and thinning out of excess fruits.
The upshot is that some brown rot is showing up on ripening plums. But not all of them. And those that have been spared are delectable. Even the birds think so. Their peckings, unfortunately, like wounds inflicted by plum curculios, increase fruits’ susceptibility to brown rot.
Tomatoes, Where Are You?
Tomatoes are growing like gangbusters, here and in other gardens I’ve seen locally. And the fruits are likewise growing very plump.
But the scene is not as rosy as it should be, literally, because too many of the tomatoes are still green. Again, other local gardens mimic my experience. How are your tomatoes doing this year?
Day after day of bright sunny, weather and moderate temperatures should have promoted ripening. Then again, day after day of rainy weather last month might have retarded it. At any rate, in gardening and farming, you can’t go wrong blaming the weather.
HOT DAYS, BUT PREPARING FOR FALL
Ignoring My Gut
Like other parents, I don’t hold back preparing for fall just because of hot, sun-drenched sunny days. But my preparations don’t entail trips to the store for notebooks, pencils, rulers, and other school gear. My daughter is old enough to gear up for herself. Instead, I’m preparing for a garden that becomes lush with ”cool weather” vegetables just as tomatoes, peppers, okra, and other warm weather vegetables are fading OUT.
Much of gardening entails NOT going with your gut. If I went with my gut, I’d be planting more tomatoes and sweet corn and, perhaps, if I was really going with my gut, even banana trees on today’s ninety plus degree, bright, sunny, humid day.
Sprouting seedlings, planting seeds, and transplants
Although tomatoes, peppers, and cucumbers presently have more appeal, fall vegetables will have their day. I have to remind myself how a lowering sun and cooler weather make more appealing the lush green leaves of cabbages, brussels sprouts, endive, lettuce, kale, celery, and, below ground, radishes, turnips, carrots, and celeriac. And anyway, I’ll have no choice because summer vegetables will have waned by then.
That lush fall garden, almost like a whole new garden, comes about only if I do something about it now!
To Every Thing There is a Season, a Time to Plant, A Time to…
Timing is (almost) everything for a productive fall garden. Planted too early, some leafy fall vegetables bolt — send up tough seed stalks — because of heat and long days. Right now, I’m sowing turnips and winter radishes, the especially tasty varieties Hakurei and Watermelon respectively. Among leafy, salad vegetables, lettuce, mustard (the variety Mizuna), and endive, with repeated sowing of lettuce every weeks until early September.
It’s still a too early for spinach, arugula, mâche, short season Chinese cabbages, and spring radishes. Some time later this month would be about right for these vegetables. My book, Weedless Gardening, gives a detailed schedule for when to plant what vegetables for specific regions.
For a truly bountiful fall garden, more advance planning was needed. For instance, I won’t be harvesting brussels sprouts until October, but for sprouts lining stalks three to four foot tall, I sowed those seeds indoors in March. Celery and celeriac seed got sprinkled in mini-furrows in seed flats way back in early February.
Zero Tolerance for Weeds, Almost
Almost as important as timing for my fall garden is weeding. The enthusiasm of many gardeners peaks in spring and then slowly wanes as summer heats up. Not mine.
Every time I see a lambsquarters weed, the thought of the eventual 100,000 seeds it might sow prompts be to bend down and yank it out. Same goes for purslane plants, whose seeds remain viable in the soil for decades. And spotted spurge; each plant not only spreads thousands of seeds, but those seeds sprout quickly to mature new plants that make even more baby, then adult, spotted spurges. How could I bring myself not to pull these weeds. (Yes, I know, lambsquarters and purslane are edible — if you like their flavor.)
With weeds kept in check through June, much less effort has been needed to maintain the status quo. Mostly, this is because drier weather has limited weed growth and seed germination, and because any watering in my garden is with drip irrigation. Rather than coaxing weed growth in pathways (and also wasting water), as do sprinklers, drip irrigation pinpoints water to garden plants.
Fresh Figs Bring Me back to Summer
Back to enjoying summer . . . we’ve been enjoying the first crop, known as the breba crop, of figs from the ‘Rabbi Samuel’ fig tree espaliered in the greenhouse.
Rabbi Samuel fig, espaliered in greenhouse
Most fruit plants bear fruits on one-year-old, or older, stems. Figs, depending on the variety, can bear on one-year-old stems, on new, growing shoots, or on both one-year-old stems and on new, growing shoots. ‘Rabbi Samuel’, I have found, bears on both.
The tree is trained to a T, with two horizontal arms growing in either direction from atop an 18” high trunk. New shoots spring up vertically at about 6 inch spacing along the arms. Late each fall, I cut all those shoots almost back to the arms to make room for and coax new fruiting shoots for the following year.
Early, breba fig crop not ripening on old stub
The stubs left after cutting back the season’s shoots are one year old, and that’s where brebas have been borne. This fall, I’ll leave some a few inches long, for a larger breba crop next July; the next year I’ll shorten them more drastically and leave others a few inches long; and so on, year after year.
The main crop, on new, growing shoots, should begin ripening not to long after the last of the brebas have been harvested. With sufficient sunlight and a bit of supplemental heat in the greenhouse, harvest of the main crop will continue until November’s days grow too short, soothing the transition from the summer to the fall garden.
SPROUTS MAKE ME HAPPY, DARWIN DOESN’T
More Citrus in the Making
You wouldn’t think that a couple of small, green sprouts could elicit so much excitement. Especially this time of year, with vigorous, green shoots sprouting up all over the place. But they did, in me. Not that anyone else would notice the two sprouts.
The sprouts were from grafts I made a couple of months ago. Over the years I’ve done hundreds of successful grafts; these two were special.
The first was citrus, special because the trees are subtropical and evergreen. The many apples, pears, and plums that I’ve grafted over the years are deciduous. I graft them when they are leafless and just about ready to start growing. Because the grafts are leafless, the wood, as long as the graft union is sealed, won’t dry out.
Not so for citrus, more specifically for the stems I clipped off my potted Golden Nugget tangerine tree. What was needed, then was a rootstock on which to graft that stem. The result would be a Golden Nugget plant above the graft (which stays right where it is no matter how much the plant grows). Clipping all the leaves from the stem forestalled moisture loss.
My home is also home to kumquat, another citrus that lives in a pot here, outdoors in summer and in a sunny window in winter. A couple of February’s ago, I glanced down at the kumquat seeds I had just spit out from fruits I harvested and ate. Not being able to squander their potential, I planted them in pots. A decade might have gone by before they were old enough to bear fruit but, after two years, the pencil-thick stems were large enough for grafting.
Citrus graft, a success
With kumquat rootstocks poised for the operation and Golden Nugget scions (the stem to be grafted atop the rootstock) stripped of leaves and also ready, the procedure was the same as for apple trees and other deciduous plants: matching, sloping cuts on rootstock and scion held in place by a wrapping with a rubber strip; covering the wound to prevent moisture loss. My usual choice of covering is Tree-Kote, which gets painted on, or Parafilm, a stretchy film that adheres to itself.
The citrus scion was fleshy enough to also lose moisture right through the bark. To prevent this, I wrapped the whole scion in the Parafilm. A blackened scion had followed previous attempts at grafting citrus without wrapping the stem.
A week or so ago, it was time to unwrap the Parafilm from around the stem. If the grafted parts were going to knit together, they should have done so by then. Lo and behold, a small, green sprout soon pushed out from the top bud of the scion.
Nutty Grafting
Not all deciduous trees are as easy to graft as apple and pear. Nut trees in the Juglandaceae family, which includes black walnuts, English walnuts, butternuts, pecans, and hickories, are notoriously difficult. Part of the reason is because cutting a stem in spring, which is, of course, unavoidable when grafting, makes these trees bleed, messing up the works.
With a slew of failures at grafting this family under my belt, I needed to try again. The candidate this year was a nut tree called buartnut, and hybrid tree with a hybrid name, the latter a non-euphonious combination of the words “heartnut” and “butternut.” Heartnut is a Japanese species of walnut, notable mostly for how easily it cracks to yield two heart-shaped nutmeats. Butternut is a richly flavored nut borne on a native tree that is becoming increasingly rare because of a blight disease.
Buartnuts allegedly need cross-pollination to bear nuts. My tree, large and spreading though only about 15 years old, lacked a mate. The mate needn’t be a whole other tree; a branch from another tree, grafted on my tree, would suffice and avoid the need to plant a whole new tree or wait the years it would take to flower. Grafted branches bear much more quickly than new trees.
Fortunately, I knew of another buartnut tree that could provide pollination. Last winter, I clipped off a few of its stems, packed them in a plastic bag, wrapped the bag in a wet towel, and then packed that whole mess into another plastic bag and then into the refrigerator. There, they remained hydrated and dormant until needed.
Heartnut graft, one sprout
The key, I’ve been told, to grafting Juglandaceae, is to wait in spring until a spate of 80 degree plus weather is predicted. Conditions seemed right on a day last May. Because of past failures, I attempted numerous grafts, three different kinds: the bark graft, the banana graft, and the whip graft. To promote bleeding off-site rather than at the grafts, I slit stems below the grafts. I covered one of the bark grafts with a plastic bag and then, for shade so the stems wouldn’t cook, a paper bag.
Almost all the grafts failed. Except one. Just one stem of just one of the bark grafts (each of these bark grafts carries 4 or 5 stems) sprouted. How exciting!
Temple Disruption
Exciting goings-on in the blueberry patch also. Birds are flitting about every morning, enjoying a few berries despite our repeated efforts to secure any openings in the walk-in “Blueberry Temple.” I threaded some string to more tightly join the top and side netting. As previously, I think this will solve the problem.
Then again, this may be a Darwinian experiment. Birds never used to work their way into the Temple. Openings in the top netting are 1” across; I fear the net is breeding for smaller models of cedar waxwings and catbirds. Or perhaps smarter ones better at finagling their way to the blueberries
