SUSTAINABLE DIRT

November 19, 2015/13 Comments/in Gardening, Planning, Soil, Tools, Vegetables/by Lee Reich

Dirt is Free, Almost

   Sustainability is such a buzzword these days. Okay, I’ll join the crowd and say, “I’m growing fruits and vegetables sustainably.” But is this true. Can they really be grown sustainably, that is, in such a way to be able to continue forever?
   As any plant grows, it sucks nutrients from the soil. Harvest the plant and you take those nutrients off-site. Eventually, those nutrients need replenishment. That’s what fertilizer does, but spreading fertilizer — whether organic or chemical — is hardly sustainable. Organic fertilizers, such as soybean meal, need to be grown, harvested (taking nutrients off site), processed, bagged, and transported. Chemical fertilizers need to be mined and processed, or manufactured, and then also bagged and transported.
   About half the volume of most soils is mineral, the rest being air, water, and organic matter. The mineral portion derives from rocks that, with time, temperature changes, and the jostling and chemical action of plant roots, fungi, earthworms, and other soil microorganisms, are ground finer and finer. Plant nutrients once locked up in those rocks become soluble and available to plants. Over time, a soil naturally offers a pretty much unlimited supply of plant nutrients. That sounds sustainable . . . but wait; three important caveats.
   First, it takes time to release those nutrients. Remove too much too fast and it’s like taking money out of the bank faster than you put it in.
   Second, one very important nutrient, nitrogen, does not come from rocks. It comes from the air, “fixed” by soil microorganisms, then incorporated into plants. As plants die, the nitrogen is incorporated into the organic fraction of the soil, from which it is slowly released into the ground for other plants to use — unless it washes away or becomes a gas again. Nitrogen is the most evanescent of plant nutrients.
   And third, a soil could be naturally lacking in one or more essential plant nutrients. If so, the deficiency needs to be corrected by bringing in and spreading what’s needed.

Hay, Time, & a Little Manure

Okay, here’s my stab at sustainability: My vegetables get “fed” only compost, a one-inch depth laid on top of each bed each year. This much compost releases enough nitrogen, as well as other nutrients, to keep plants happy and healthy for a year.

The season’s last hay gathering

   But the sustainability meter must examine what goes into the compost. The bulk of my compost is made from hay harvested from my one acre hayfield. Here’s the rub: If I harvest the hay too frequently, I’m mining the soil, pulling out nutrients faster than they are naturally replenished. So I focus on different parts of the field in different years, giving previously harvested portions time to rejuvenate.
   Early morning forays into the field with my scythe provide enough hay for compost making during the growing season. Last week, I did what I do each fall, attaching the brush hog to my tractor and mowing the whole field. (Mostly, this prevents the field from morphing over time, first to a field of brambles, multiflora roses, and autumn olives, and then on to forest.) After brush hogging, I rake up a few clumps of hay here and there for the final “feeding” of the season’s compost piles.
   This end-of-season stuff is not very nutrient-rich, so what little I harvest takes little from the field in terms of nutrients. This cutting mostly supplies carbon compounds, which it got from via photosynthesis from carbon dioxide, to feed the compost microorganisms.
   Keeping an eye on the character of the hayfield should give me some idea of how it’s doing nutritionally. More grasses, more nutrients. Areas of goldenrod, yarrow, and other forbs get mowed, but not raked.
   My compost pile also gets fed horse manure that I haul in from a local stable. My use of manure is sustainable only in the sense that it’s someone else’s waste product. Other additions to my compost pile are kitchen scraps and spent garden plants (which recycles rather than adds nutrients), and old blue jeans and other biodegradable clothing. Using humanure (see The Humanure Handbook by Joseph Jenkins), if I had a composting toilet, would further close the nutrient cycle.
   Two final additions, sustainable except that they need to be transported here, are ground limestone and kelp. The limestone holds soil acidity near neutral, which, among other benefits, puts nutrients in forms most accessible to plants. The kelp, replete with a spectrum of micronutrients, is for insurance, just in case my soil naturally lacks any essential plant (or human) nutrient.

And Now for the Cart’s Sustainability

Garden cart, all dressed up in aluminum

    Hay is bulky stuff; same goes for manure. I move all that bulky stuff to my compost piles, then move the finished compost away from the piles. All this moving is done with the help of my “Vermont garden cart,” which has two heavy duty, bicycle-sized tires sitting just about midway across a sturdy plywood bed surrounded by three sturdy plywood walls. Although the cart can haul up to 400 pounds, shoveling out manure or compost scrapes away at the plywood base. That, along with jabs from the pitchfork as I pile in hay severely compromised the wood . . . until this summer.
   A sheet of aluminum, a friend’s brake for making sharp bends in the sheet, and some screws, and I had the bottom of the cart, and a few inches up each side, protected from my shovel, pitchfork, and moisture. These carts should be sold already aluminized.
   The only problem is that aluminum is very unsustainable. Although abundant, enormous amounts of electricity are required to free it from the raw material, bauxite. On the plus side, aluminum is very long-lasting; I’ll never have to replace it in my carts.

SWEET ANNIE AND SWEET GRAPES

November 11, 2015/2 Comments/in Design, Flowers, Fruit, Gardening/by Lee Reich

Annie Helps the World

    Sweet Annie (Artemisia annua): such an unassuming name. Likewise for the plant itself, with its ferny, but not distinctive, foliage, and flowers not worth a second look. You’d hardly peg this plant as a player in global health and global warming.
   But look within the leaves and you find artemisin, a biologically active compound that has contributed to Sweet Annie’s figuring into Chinese herbal medicine for the past 2,000 years. Artemisin was isolated from the plant in the 1970s by Chinese scientist Tu Youyou, for which she shared a Nobel Prize. Sweet Annie’s uses in Chinese medicine — qinghao in Chinese — run from treating asthma to skin diseases to stomach pain to rheumatism to . . . but not all such claims have been experimentally verified (and Sweet Annie could have bad side effects).
   The most widespread and thoroughly documented use of Sweet Annie is, in combination with other drugs, in the treatment of malaria, a disease responsible for over a half a million deaths per year. One roadblock to the more widespread use of artemisin is its cost.
   Which brings us to global warming, or, more specifically, the increasing concentration of carbon dioxide in our atmosphere, which is one cause for global warming. Carbon dioxide, for all its bad press, is one ingredient in the recipe for photosynthesis. The carbon in carbon dioxide is what becomes the organic carbon in a plant’s cellulose, starches, sugars, fats, proteins, and other essential building blocks that store energy and build a plant’s physical structure. More carbon dioxide in the atmosphere could translate into greater growth, although increased temperatures from global warming could have the opposite effect.
   In the case of Sweet Annie, research by the USDA indicates that a more carbon dioxide rich future would lead to more growth, which translates to greater yields of Sweet Annie and more artemisin for treating malaria.

Annie, for Sweet Aroma

My two Sweet Annie plants aren’t destined for drug production. They’re for olfactory pleasure. Tied into bundles and hung in the mudroom alongside the front door, the bundle will effuse its camphor-sweet aroma each time a breeze or a person brushes past.

Annie’s a Weed?!

    Sweet Annie is a self-seeding annual that, like some other members of the wormwood family, can become weedy. Which makes it perhaps unwise that I planted it where I did.
   Garden areas closest to my front, back, and side doors are the ones that get most care and that I look at the most; these considerations guide my plantings, both for aesthetics and for pragmatism. Things get wilder as you move further from the house, the most dramatic example of which is the meadow that begins where the lawn ends.
   So it was perhaps foolish to plant Sweet Annie, which is not much to look at and could become weedy, in the bed next to my terrace. Having the fragrant leaves close by was one rationale. But for some reason, that one bed is cared for the least, perhaps because or perhaps consequently it has become a dumping ground for miscellaneous plants for which there are no obvious homes.
   That bed is also home to chamomile. Again, one rationale was to have it nearby so I could conveniently pluck flower heads for tea — which I do. But really, no other home presented itself. I planted chamomile there many years ago and got scared of its seeding all over the place. With diligence, I was able to get rid of it — until this year, when I replanted it. I’ve been warned (by myself).
   I even planted mint in that bed, again, to have it handy for tea, but knowing how it could, and once did, knit the soil, just beneath the surface, with its lacework of stolons from which sprouts new stems. I did have the foresight, this time, to contain the roots by planting the mint into a chimney flue sunk into the ground. Constant attention will be needed to prevent the stems from flopping down over the sides of the flue to root — which they do very easily — where they touch soil.
   From today’s perspective, a handy little garden overflowing with sweet aromas is appealing. I’ll see how I feel next year at this time.

Sweet Ice Grapes

Hanging from vines on the arbor over the terrace are remnants of the season’s grapes and the white paper bags that protected some of the bunches. I found a few bags still with unharvested clusters, frozen but still intact. “Ice grapes,” the precursor to “ice wine,” except that these are eating grapes. They were smooth, sweet, and flavorful.

Grapes, frozen but delicious

NUTS OVER CHESTNUTS

November 5, 2015/6 Comments/in Fruit, Gardening, Planning/by Lee Reich

American Chestnuts, Gone but not Dead

The chestnuts are big and fat and tasty — obviously not American chestnuts. I harvest so many chestnuts, also big and fat, each year from my Colossal variety trees that I never bothered to look beneath my Marigoule trees. Marigoule is planted further from my house than Colossal.

Marigoule chestnuts

American chestnuts, Castanea dentata, are small but very tasty, or so I have read and heard. I’ve never tasted one. The trees were devastated by a blight throughout the early 20th century. Previous to blight, the trees were so numerous in our eastern forests that it was said that a squirrel leaping from one chestnut branch to another could travel from Maine to Georgia without touching the ground.
Something like 40 billion trees died to the ground. But roots survive, sprouting new shoots each year to provide a host to keep the blight fungus alive. Trees might even grow to have trunks a half-foot or more in diameter before the fungus strikes to cut the tree to the ground again.

A Tale of Blight, Pollination, and Staining

Various chestnut species inhabit different parts of the world. Most blight resistant are Chinese chestnut (C. mollisima) and Japanese chestnut (C. crenata), where the blight originated. European chestnuts (C. sativa) is susceptible to blight, so has been mated with the Chinese or Japanese species to yield resistant, tasty hybrids. My Colossal and Marigoule trees are hybrids of the European and Japanese species.
But the plot thickens. Colossal, though a hybrid, is only slightly resistant to blight. My tree, over 15 years old, exhibits no sign yet, but I’m keeping an eye out for telltale orange pustules on its bark, limb dieback, and massive resprouting below points of infection. (It is only more recently that Colossal was determined to be more susceptible than originally thought.)

Chinese chesstnut seedling

Marigoule is quite resistant to blight. The tree also has an elegant, upright form, more like that of American chestnuts.
   So what’s the problem? If blight were to eventually strike Colossal dead, I could just walk a little further and gather Marigould nuts from the ground. Except that any chestnut tree needs cross-pollination from another variety in order to bear nuts.
   When I planted Colossal and Marigoule, I also planted some other chestnut trees, blight resistant Chinese chestnuts: a seedling and the varieties Peach and Eaton, the latter of which also has Japanese and American chestnuts in its parentage. All these yield good-tasting nuts, though not nearly as large and easy to peel as Colossal and Marigould, all are blight resistant, and any of them could pollinate Marigoule. Problem solved? Not quite.
   The plot thickens further. The nuts of Colossal, Marigoule, and other Japanese and Japanese hybrid chestnuts sometimes get a black staining that ruins their quality. Not all the nuts, just some of them. Recent research pins the blame not on yet another disease, but on pollen from Chinese or Chinese hybrid chestnut trees.

Nutty Present and Futures

    Going forward, I’m keeping a close eye on Colossal. If Colossal gets sick, one option that, so far, has been effective only in Michigan, might be to infect the blighted trees with a blight fungus that has been weakened because of infection with a virus. The weakened fungus is less deadly.
   Or, I could cut down Colossal and Marigoule, and feast only on the Chinese chestnuts and their hybrids. But Colossal and Marigoule are both so productive and produce such large, tasty, easy to peel nuts.
   I could cut down the Chinese seedlings and hybrids to prevent their pollination and staining of Colossal and Marigoule nuts. Except I’ve recently discovered that my Marigoule must have been pollinated by one of my Chinese trees because Colossal is pollen sterile. Marigoule can pollinate Colossal, but not vice versa. So to get nuts on Marigoule without Chinese chestnut pollen, I’d need another Japanese chestnut or hybrid, either a whole new tree or a branch grafted on either Colossal or Marigoule.. The variety Labor Day (also known as J60) yields good nuts and is blight resistant.
   I’ll probably take the “wait and see” option. After all, there’s no sign of blight on any trees; few nuts get staining; and we gather more than enough nuts for roasting and stews.

CLEAN UP, THEN SHAVE

October 28, 2015/14 Comments/in Flowers, Fruit, Gardening, Pests, Soil, Vegetables/by Lee Reich

Out with the Old (Plants)

   Ostensibly, I’m clearing away old plant debris from the vegetable and flower gardens to spare next year’s garden a full onslaught of overwintering disease and insect pests, and so that, come spring, the soil is ready and waiting for seeds and transplants. I’ll admit it, though: I like the garden looking neat going into late autumn. As Charles Dudley Warner wrote in his book My Summer in the Garden (1889), “the closing scenes need not be funereal.”
   As of this writing, frost has not yet struck; as of your reading, it probably will have. Following that event, I will remove all dead plants. I’ll grasp the tops of smaller plants, such as marigolds and basil, give them a twist to sever the smaller roots, then lift and toss the plant into a waiting garden cart. If I tried to do that with old pepper, tomato, or okra plants, they would laugh at me. I lop off the bulk of their tops, then cut around the plant with a Hori-hori knife so that I can lift the remaining stem and main roots out of the ground.
   In either case, my goal is to remove everything but the smaller roots. Left in place, they’ll rot to add organic matter to the soil, leaving behind channels to let air, water, and creatures move through the ground.
   Even now, before frost, cleanup is well under way. Tomatoes are spent; I cleaned them up yesterday. Beans are spent; I’ll clear them away today. Leaving bean roots in the soil is like sprinkling organic fertilizer from the free nitrogen they gathered from the air.
   Along with garden plants, weeds also get cleared away, again removing only top portions and the main roots. Small roots don’t have the energy to re-sprout.

In With the New (Compost)

More than just looking neat, the cleaned up garden is — to my eye — ornamental. Think of the calm beauty of Zen gardens, some of them little more than boulders and raked gravel. Mine is wood chips (in paths) and raked soil.

Beds in fall: veggies, oat cover crops, compost

Well, not really raked soil. Bare soil looks ugly to me because I know it’s too exposed to rain and wind. So as soon as I’ve cleared a bed, I immediately put a blanket on it. Before the end of September, that blanket was oat seed topped with an inch of compost. Those beds are now lush strips of green. Post-September beds get blanketed with just an inch of compost. It’s roughness helps protect the surface, and next spring I can sow seeds or plug transplants right into it. That much compost is all the nourishment plants will need for the whole growing season next year.
And then there are the beds still green with carrots, turnips, endive, lettuce, kale, and other cold-hardy plants. I’ll dig the root crops, for storage, at my leisure. The others, we will eat, also at our leisure.

Nothing Wasted

    All that stuff that I am clearing out of the garden is going right into the compost pile. Yes, everything! I’m occasionally asked if I put leaves and stems that are infected or infested with blight, aphids, or other pests into my compost pile. Yes! Everything goes into the pile.
   I contend that if you looked closely enough (perhaps needing a microscope) at almost any leaf, stem, fruit, or root, you’d probably find some evidence of a “bad guy” on it. No matter. The combination of time and temperature within any compost pile does them in.
   This time of year, piles build rapidly. By paying attention to water and air within the pile as well as the balance of high nitrogen materials (manures and lush greenery such as vegetable plants and young weeds) and high carbon materials (old, browning plants, wood chips, autumn leaves), I’m able to get my compost piles up to 160° F.
   Soon, cooler temperatures combined with less stuff to feed the pile makes for cooler composting. I let these piles “cook” longer, the longer time making up for lower temperatures.

Lookin’ Good and Ready for Spring

Getting everything ready for winter is a leisurely process, inching along over the next few weeks. By then, tender vegetable plants and weeds will have been tucked into compost piles and beds will be blanketed in either compost, compost and growing oats, or late fall vegetables. Mr. Warner, mentioned in my opening paragraph, went on to say, “A garden should be got ready for winter as well as for summer . . . I like a man who shaves (next to one who doesn’t shave) to satisfy his own conscience, and not for display, and who dresses as neatly at home as he does anywhere. Such a man will be likely to put is garden in complete order before the snow comes, so that its last days shall not present a scene of melancholy ruin and decay.”
I’m going to shave now.

Luxuriating in my Greenhouse

October 22, 2015/7 Comments/in Fruit, Gardening, Planning, Vegetables/by Lee Reich

How Cool is That (Greenhouse)?

    Having a greenhouse is a much-appreciated luxury. To avoid being profligate, I eke all that I can from its every square inch in every season.
   For starters, it’s a cool greenhouse — temperature-wise “cool,” not “ain’t this a cool greenhouse” cool. Winter temperatures are permitted inside drop to 35°F. before the propane heater kicks on. And in summer, roll-up sidewalls let in plenty of cooler, outside air to save energy (and noise) in running the cooling fan. Demands on the cooling fan are also minimized by letting summer temperatures reach almost 100°F. before the fan awakens.
   I have to choose my plants carefully for them to tolerate such conditions.
   Right now, lettuce, arugula, mâche, celery, parsley, kale, and Swiss chard seedlings and small transplants trace green lines up and down ground beds in the greenhouse. I sowed seed of most of these cold-loving vegetables about a month ago. They’re too small to harvest now. No matter: The outdoor vegetable garden is still replete with greenery available for harvest through November and, probably, on into December. By then, greenhouse greenery will have grown to harvest size, then continue to do so very slowly through the dark, cold days.
   And the 100° summers in the greenhouse? Above the beds spread the branches of three large fig trees, planted right into the ground (rather than pots). From those branches dangle ripe and ripening figs, as they have since July. Figs originated in the searing heat of summers in Western Asia; they can take the 100° heat of my greenhouse. Soon, cooler temperatures and lowering sun will drive the trees to stop ripening fruits, and lose their leaves and enter dormancy. (Figs are subtropical, rather than tropical, trees, so enjoy a cool — but not frigid — winter rest.) The few, leafless branches, most of them pruned back, will cast little shade to let the cool weather greenery in the ground beds below bask in what little sunlight fall and winter have to offer.
   Starting in February, my greenhouse does triple duty, becoming also a home for transplants for the upcoming season’s vegetable and flower gardens. I plant the first seeds — onions, lettuce, celery, and leek — in early February, sowing them in seed flats on the narrow bench along the greenhouse’s north wall.

(Hot) Beds in Summer

As each spring morphs into summer in the greenhouse, fig growth begins anew and winter’s cool weather vegetables wane and are cleared away.
How about putting the ground beds beneath the awakening fig trees to some good use? In the past, I’ve tried growing melons and cucumbers, all of which originated in hot regions of Africa and Asia, in those beds. Neither the melons nor the cucumbers did particularly well — yet.

Ginger Loved the Heat

    Which brings us to this week’s ginger harvest. Greenhouse beds this summer provide a warm, moist home in which to grow ginger, a plant indigenous to the hot, muggy climate of south China. Ginger would be hardly worth growing if all I wanted was the khaki-skinned rhizomes that I could pick off a supermarket shelf. Those tough-hided roots are mature ginger, which has a fibrous flesh.
   What I was shooting for was baby ginger, whose pink-tinged, white skin, encloses flesh that is tender, lily-white, and free of fibre. The flavor is a little different than mature ginger, cleaner. This tropical plant I figured could — and it did — thrive in my hot greenhouse all summer.
   To get started, way back in March, I purchased a single root of mature ginger at the supermarket, broke it into four sections, and potted each section into a 4 inch pot. As I said, the plant needs heat, so I set the pots on my seed-starting mat to maintain a temperature of about 70°F. Still, it took awhile for green sprouts to show.
   The potted ginger plants were ready to plant out in a greenhouse bed just as the last of winter’s vegetables were being cleared away there. After planting, I refurbished the soil with a mulch of compost. Cool soil got the plants off to a slow start but once summer heat kicked in outdoors, and then really kicked in within the greenhouse, the ginger thrived.
   The goal was to let ginger linger to eke maximum yield but not so long that the rhizome would begin to mature. I also needed space for this winter’s plantings. As it turns out, the first objective, maximum yield, was moot. Yields were prodigious, four plants yielding much more than we could possibly eat.

Pickle It

The first order of business with the harvested baby ginger was to pickle it. All that was needed was to slice it thinly with a carrot peeler then pour boiling vinegar sweetened with a bit of maple syrup over it.

I Find Common Ground, and More, in Maine

October 14, 2015/3 Comments/in Design, Flowers, Fruit, Gardening, Uncategorized/by Lee Reich

My Favorite Country Faire

   Two dogs, one cat, six ducks, and one chicken are trusted to the care of friends; sourdough starter is re-fed and chilled; plants are on their own. It’s hard to leave the farmden. But this trip — to Maine — is well worth it.
   Walking through the entrance gate to the Common Ground Fair in Unity, Maine, my senses are overloaded with color and fragrance. Along either side of the entrance path are boxes piled high with bright orange carrots, spilling over with the blue green leaves of kale, or packed full with yellow or red beets. Also flowers, herbs, and cheeses. Pervasive is the resiny fragrance of sweet Annie (Artemesia annua), which for some reason seems to be perennially the signature herb of the fair. Buckets are filled with stems for sale; knapsacks sprout bunches of purchased sweet Annie from their zippered pockets; and girls and women sport woven sweet Annie headdresses. From the shade of tents on either side of the walkway, Maine’s myriad organic farmers are hawking their wares.
   Sweet Annie isn’t the only fragrant herb at the fair. In the tent devoted to some of Maine’s political groups, buds of marijuana — medical marijuana — are available for olfactory sampling.
   Central to the Common Ground Fair, like all country fairs, are agriculture and rural skills. A team of oxen strain under the weight of logs they are pulling. Border collies bead down on sheep, demonstrating their herding skills and the training skills of their owners. A bearded, young man swings an adze as the log on which he is standing takes on a square cross-section. Another bearded man helps a young boy pull a bow back and forth until smoke curls up from the round, maple peg rubbing the round notch in a maple board: fire-making without matches.
   In other tents, these with closed, darkened flaps, someone standing near a flap holds the attention of a seated crowd in the darkened interior. No, not a cult gathering. Throughout each of the three fair days, workshops are offered in such diverse topics as “Farm-Raised Kids on an Organic Farm in Maine,” “Backyard Grain Growing,” “Advanced Seed Saving,” “Growing Grass-fed Vegetables,” and “Weedless Gardening.” (The last was one of the three workshops I held at the fair.)

Old-Fashioned Fun

    Common Ground Fair is “retro,” an improvement on country and county fairs, in doing less. No amplified voices of barkers try to woo you in to win a stuffed gorilla. In fact, a three-year-old boy trying to pound an oversize sledge hammer onto a pad as a test of strength, with a lot of help from his mom, was the only strength or skill test I saw — and no prizes offered.
   No rides either. No fun? Given the happy whoops of the slew of children running up a grassy slope with flattened cardboard boxes, then jumping on them with a running start to slide down, I’s say they were having fun.
   Just about everything at the fair is made or grown in Maine. (Used to be that everything had to be grown in Maine, which put coffee drinkers on edge. Maine-roasted coffee is now available at the fair.)
   Twilight is wondrous at the fair, mostly because you can see the twilight. No strings of electric lights bring the fair to new life at the end of the day. Most people leave. The only light, besides the setting sun, is the soft, yellow glow of lanterns or campfires. The fragrance of the campfires and the sounds of campers’ home-grown music around the campfires are the parting senses as I leave the fair.

My Favorite Garden Designer

    Beatrix Farrand is a name that most people do not recognize, although she was a woman who created some of the most beautiful landscapes and gardens in the world. And she did so at a time — in the early 20th century — when such professions were not open to women. Much of her landscape work was in Maine, on Mt. Desert Island, as was her home, Reef Point.
   Reef Point was Beatrix’s family estate; under her care, it evolved into a horticultural heaven, with garden areas woven together by grassy paths. Spruce trees created microclimates that allowed azaleas and other plants not usually adapted to cold of Maine winters and the buffeting by ocean winds to survive and thrive. The gardens, the experimental plantings, and their descriptions in Farrand’s Reef Point Bulletins were all part of her vision of Reef Point as an educational enterprise.
   Alas, Reef Point Gardens did not fulfill the vision: wildfire and lack of funding forced Ms. Farrand to down-size. She dismantled Reef Point and moved to an addition she had built attached the home of Lewis and Amy Garland, the superintendent and chief horticulturalist of her Reef Point Estate.
   Garland Farm — my last stop on my visit to Maine — was Beatrix Farrand’s final design, incorporating many architectural elements and plants salvaged from Reef Point. In contrast to Ms. Farrand’s other projects, which included designs for Princeton University, Rockefellers’ Seal Harbor estate, The Mount (home of Edith Wharton, Beatrix’s aunt), Dumbarton Oaks (my favorite of all gardens), and the Santa Barbara Botanic Garden, Garland Farm is a small garden.
   Looking out the French doors of Ms. Farrand’s study at Garland Farm onto the small parterre garden, your eyes are carried along a path to a Buddhist statue. Along that path are beds home to lavender, heathers, and other plants with year ‘round effect. The whole area is defined by a low balustrade, setting it off from the view of the meadow and grove of Norway spruce trees in the distance. This garden incorporates the same design principles — axis, year ‘round effect, structure, and integration of views — on an intimate scale, that were so successful in Beatrix Farrand’s larger projects.

SUCCESSES, EDIBLE AND OTHERWISE

October 2, 2015/9 Comments/in Design, Flowers, Gardening, Vegetables/by Lee Reich

Stand Up Straight!

I am particularly proud of my Brussels sprouts this year — and I haven’t even tasted them yet. How odd that I should be proud of this vegetable that I spurned in the past, often quoting a friend who referred to them as “little green balls of death.” Then I put my own twist on that description, saying that perhaps the friend meant that Brussels sprouts were only palatable a “little boiled to death.”
I’ve come around, and decided, a couple of years ago, that Brussels sprouts were worth growing, despite their high demands on space and time. For good production in northern climates, the seeds need to be sown indoors in early March, and then harvest doesn’t start until October or sometime after the first frost. And for all that waiting, each plant — a mere single stalk with whorls of leaves from top to bottom and a sprout at the base of each leaf — takes up an area of about three feet by three feet.

Gustas Brussels sprouts, standing up straight.

   Things would be bad enough if a Brussels sprouts plant just grew straight up to fill its allotted area. But the plant can’t support itself, so in its youth it flops down on the ground. Once that supine stem has created a firm base upon which to rise, the end of the growing stem curves more or less upward according to original plan. That youthful waywardness wastes and muddies lowermost sprouts, with the sprawling plant demanding even more space, which is a problem in an intensively-planted garden.
   This summer, before the plants even had time to consider flopping down, I poked a bamboo pole into the ground next to each one, which I tied to the pole, adding ties to keep up with growth. Perhaps a bit too orderly for a vegetable garden, but my Brussels sprouts “trees,” each now over four feet tall, look quite attractive.
   The “trees” are not likely to grow much higher because I pinched out the top bud of each plant in early September. This pinching redirects the plants energy from the highest growing point to the side shoots — which are the sprouts. All month, the sprouts have been fattening, soon to be snapped off and eaten.

Not Your Average Marigold

    I also count among this season’s successes two little-known flowers, both of which elicited “oohs and ahhs” from visitors here. One of the flowers were Signet marigolds. You might think, marigolds?, they’re okay, but more “ho hum” than “ooh and ahh.” Not so.
   Signet marigolds, Tagetes tenuifolia, are a different species from common marigolds, and they look a little different. Mostly, they’re smaller, expanding into amorphous mounds of fine, lacy, lime-green leaves, from which stare out small yellow or orange blossoms — most charming. A lemony-marigold aroma wafts from both the blossoms and the leaves.
   Actually, the aroma can waft over the whole garden if you plant enough Signet marigolds — which I did this year. In the past, the seeds never germinated very well for me, so I just spot planted what few seedlings I could raise here and there in the garden.
   This spring, in mid-April, I sowed the seeds densely in an 8 by 6 inch seed flat. The dense planting led to an excessive number of crowded seedlings. While they were still young, I gently lifted each one to transplant into its own potting-soil-filled cell to grow for a month or so before planting out in the garden.
   The few plants I poked in at the feet of vegetable beds on either side of the main path through the vegetable garden have grown into sprawling mounds that wash into the main and side paths of the vegetable garden like seawater into an undulating beach. The flowing mounds effectively soften any excessive orderliness of the garden — from the soldier-straight Brussels sprouts plants, for example.

A Cardinal in our Midst

    My grape arbor creates a horizontal roof nine feet above my terrace. Each of the four grape vines rises to that height on a single trunk. What an opportunity for a climbing vine, especially one that climbs by twining! My other floral success this year has been with such a twining plant, cardinal climber (Ipomoea x multifida, a hybrid created by mating I. coccinea and I. quamoclit).
   In the past, other species of Ipomoea climbed those trunks. Morning glory was one, but that only blooms, of course, in the morning. Moonflowers have also dressed up the trunks, but they bloom only at night.
   So this year, cardinal climber was the Impomoea species for the grape trunks. It blooms all day long, clothing itself in blossoms from top to bottom. The size and color of the blossoms, an inch or so across and cardinal red, seem best for relatively close viewing when sitting on the terrace.
   No need for these flowers to soften any excessive orderliness of the arbor. The grape trunks wend their way skyward and their long, new shoots create plenty of disarray except right after they are pruned each spring.

VEGETABLE GARDEN FRUITS

End of Summer But I Still Need some Watermelon

    Given sun, heat, and reasonably moist, fertile soil, watermelons are easy to grow. The greater challenge is in harvesting them at their peak of perfection. Even professionals sometimes fall short, as witnessed by not-quite-ripe watermelons I “harvested” awhile ago from a supermarket shelf and, a couple of weeks later, from a table at a local farmers’ market.
   That was while I was waiting for my own watermelons to ripen — the delectable variety Blacktail Mountain. But should I have been waiting?
   All sorts of indicators are touted for telling when a watermelon is ripe. The part of the melon laying on the ground supposedly turns yellow. The tendril opposite where the melon in question is attached dries up. Or my favorite method: thumping. Knock you knuckles on your forehead, your chest, and your stomach. The sound of a ripe watermelon should match the sound of the chest thump. The forehead sound indicates that the melon is underripe; the stomach thump, overripe.

Watermelon, it was ripe & delicious

   Sure, one could pull out the bells and whistles. As I wrote, even professionals have problems determining watermelon ripeness. To aid in commercial harvesting, nuclear magnetic resonance, one possibility, was considered — at $60,000 to $1,000,000 — out of budget. Acoustic resonance testing ($950) was a more viable alternative, but still not for me, with my five plants.
   After my two disappointing purchases, my mouth was watering for my own melons. I ignored the question mark hovering in air above the largest of the lot and, despite its lack of a dried tendril, a yellow bottom, or a telltale thump, cut it from the plant. Long story short: It was delicious, perhaps just a tad overripe.
   What about the other waiting melons? I’m just going to harvest them, as needed, and hope for the best.
   Update: I may have one more addition to the imperfect list of watermelon ripeness indicators. It seems that ripe melons might develop a whitish, waxy “bloom” on their skins.
    Update on the update: Scrap that way bloom indicator. Or, it might be part of the picture. Now I look for a number of indicators, and if some indicate ripeness — I thump the melon before picking.

Next Year: More Watermelon Plants

Part of the watermelon problem is that I don’t grow enough watermelons. I once lived and gardened in southern Delaware, a few miles from one of the epicenters of watermelon production. With ideal climate and soil (sandy), I grew an abundance of large watermelons. Whether or not a single melon was picked underripe was not so critical. Once ripening began, any unripe ones could be relegated to the compost pile; a better one was always in the offing.

My Favorite Vegetable (Fruit?)?

Like watermelons, sweet corn is also easy to grow. It can get by with less heat than watermelon, but demands a more fertile soil. Harvesting sweet corn at its peak of perfection also can be a challenge, though not nearly the challenge of watermelon. Picked too soon, corn is tasteless and toothless; picked too late, and it’s too starchy and toothy, a delight for animals, excepting humans.
The first hint as to when I get to pick corn is when tassels atop the stalks begin to shed pollen grains — millions per tassel!

Corn, testing for ripeness

About three weeks later, I start peering into the corn bed to look at the silks spewing out the ends of each ear. Silks are more or less dry on a ripe ear. At that point, I can usually tell ripeness by just wrapping my hand around the ear to feel its fullness, although less than perfect pollination can drain the bulk of a ripe ear so it feels underripe. (It’s hard to imagine less than perfect pollination when you consider that each tassel sheds literally millions of pollen grains; then again, each grain remains viable for only a few minutes; then again, again, it can travel hundreds of feet in that few minutes; then again, again, again, each kernel only develops if a pollen grain lands on a germinates on the single silk to which it is attached.)
   Any doubt about ripeness, and it can be confirmed before committing to harvest by peeling back the husk just enough to see some kernels. Their color and plumpness might be a giveaway. If not, a thumbnail pressed into a kernel should yield a milky fluid.
   Sweet corn, in contrast to watermelon, is easy to produce in quantity, even in a relatively small garden. So tasting an ear is no great sacrifice; there’s plenty more.
   Hybrid varieties of corn tend to ripen uniformly, so once one ear in a bed is ripe, the whole bed is likely also ready for harvest. A bed of a non-hybrid variety requires more frequent assessment and harvesting, which is better for home use where you might want a few ears each day or so, rather than a once-over harvest. With successive planting and selective harvesting, we’ve been enjoying sweet corn almost daily since the end of July.

ON TRIAL

And the Best Cherry Tomato Is . . .

Take your picks from the descriptor grab bag: Honey, Gold, Drop, Sun, Bunch, etc. Now put a couple of them together and you might end up with a luscious-sounding name for a tomato variety. People have done this, and reeled me right in. This year I got fished into planting a few, new (for me) varieties of cherry tomato.
Sungold is the gold standard of cherry tomatoes, the one I always grow. Its rich aroma underlies a sweetness livened with just the right amount of tang. One problem with Sungold is that it’s an F-1 hybrid, which means that you can’t save the seed and expect the resulting seedlings’ fruits to have the flavor of Sungold. The flavor might be better, but it’s more likely to be not as good. The other problem with Sungold is that the seeds, which must be purchased, are expensive.
The first of this year’s lineup was the variety Solid Gold, a yellow, teardrop shaped tomato. Like Sungold, it’s an F-1 hybrid. Perhaps it would offer better or different, but also excellent, eating. It has been billed as having “outstanding flavor of true grape tomatoes” (by those selling the seeds). Grape tomatoes are tiny tomatoes, a different species from other tomatoes, with very good, very sweet flavor.

Tomatoes-Honey Drop, Honey Bunch, Solid Gold

   Honeybunch, the second in the lineup, is another F-1 hybrid, this one red and teardrop shaped. “As if a pearl tomato(?) had been drizzled with honey,” so they say.
   The flavor of another variety, Honey Drop, was likened to that of honeydew melon. This one’s a Sungold look-alike and is open-pollinated, so seedlings should generally yield the same fruits as the parent.
   All three of these new varieties have borne early, and their stems have been heavy all season long with beautiful golden or red fruits. One reason their stems are so laden with fruits is because we don’t pick them. Not when we also have Sungold tomatoes to munch on. Solid Gold, Honey Bunch, Honey Drop, and the unnamed variety are all very good tomatoes, but why eat a very good tomato when you can eat the best tomato?

Filbert Plague, How Bad?

Moving out into the field, literally, to my filbert (hazel) nut bushes . . . East of the Rocky Mountains, most people who plant filberts, and especially permaculturalists, plant American filberts (Corylus americana). This species is resistant to eastern filbert blight, a fungal disease endemic in these parts. I once grew American filberts, and they are beautiful in fall when their leaves turn blazing shades of red. Unfortunately, their nuts are small, with bad flavor — a good wildlife food, a poor human food.

Pustules of filbert blight

European filberts (C. avellana), and various hybrids, are what yield the large and tasty nuts of commerce. Orchards of these filberts are mostly in the Pacific Northwest. About 50 years ago, Eastern filbert blight made inroads to those orchards, which prompted breeding programs for blight-resistant varieties.
   I’ve planted a number of blight resistant filbert varieties, including some older varieties bred decades ago in the East. As it turns out, though, the the blight fungus exists in more than one regional strain; like some other fungi, the blight fungus might also morph over time.
   Join me as I walk my row of filberts and note the performance of the various varieties. Four of the plants are only in their second year and are from the New Jersey breeding program of Tom Molnar, at Rutgers. The hope is that they’ll be more blight resistant than the western-bred varieties.
   The worst of the older plants include the varieties Clark, Eta, and Hall’s Giant. Clark and Eta are western-bred, while Hall’s Giant is an older, easter-bred variety that is bearing a moderate number of good-sized nuts in spite of the blight.
   Santiam, from the west, is afflicted with a moderate amount of blight. The nuts it bears are small but still much larger and tastier than native American filberts.

Ripe filbert nuts

Least blight-infected are the western varieties Lewis and Yamhill, the Italian variety Tonda di Giffoni, and Graham, an older, eastern variety. Thus far, my favorite is probably Graham, a hybrid of American and European filberts bred by Samuel H. Graham of Ithaca, New York, and introduced in 1950. It yields the largest nuts of the lot and shows its American parentage in its wide suckering growth habit and the fiery red of its leaves in autumn.

Results May Vary

As they say in ads: “Your results may vary.” The above are my experiences. Filbert blight, like any disease, only thrives with suitable environment, a susceptible host, AND presence of pathogen. My farmden fulfills all three conditions, with varying host plant susceptibility. But I only am growing one plant of each variety; slightly different conditions might affect susceptibility of individual plants.
Now, about my cherry tomato experiences: Tomato flavor varies little with climate or growing conditions, so your results probably would NOT vary from mine. Except of course, that it’s surely a matter of taste when it comes to taste.

I WAS WRONG

September 9, 2015/0 Comments/in Design, Flowers, Fruit, Gardening, Planning, Vegetables/by Lee Reich

Hog Peanuts, Groundnuts, Whatever

I was wrong. A few weeks ago I wrongly dissed groundnut (Apios americana) for invading my flower garden. Yes, I planted it; that was 30 years ago, and it’s resisted my attempts at eradication for the past 28 years.
The worse culprit, this year at least, is related to groundnut. Like groundnut, it’s a legume, it’s native, it’s edible, and it’s a vining plant with compound leaves. But each leaf of hog peanut (Amphicarpaea bracteata), has 3 egg-shaped leaflets, as compared with groundnut’s 5 lance-shaped leaflets.

Hog peanut leaves

Hog peanuts produce flowers both above ground and below ground. Below ground is where the goodies are. Pods that form there enclose peanut-sized seeds that allegedly are tasty raw or cooked. I’ll see if I can dig some up in a few weeks. Like groundnuts, hog peanuts provided food for Native Americans; the plants were among the four sacred plants of the Osage.
So what can be bad about a plant that tolerates some shade, adds nitrogen to the soil, and yields an allegedly tasty seed below ground? The problem is that it’s run wild over the flower bed, the fine stems and leaves attempting to smother, sometimes successfully, every plant in its path. Even non-native, invasive Japanese stilt grass and garlic mustard can’t hold their own against hog peanuts.

Permaculture Reality

Low maintenance, protection and enrichment of soil, and edible parts recommend hog peanut and groundnut to permies (permaculturalists). As with so much in permaculture, these plants perform better in theory than in practice.

Hog peanut & groundnut strangling crocosmia

In humid climates, plant growth — and not just groundnut and hog peanut — can run rampant. Growth needs to be controlled and balanced, a job made more difficult in a permaculture “guild” of groups of plants working together. I’m all for interplanting different species to make best use of light, water, and soil resources, and form communities that resist pests — to a point.
   I’ve had the opportunity, over the years, to visit the permaculture garden planted by students at the University of Massachusetts in Amherst. Now in its 5th year, the garden pays tribute to the compost, mulch, and sweat students put into soil preparation. The plants have grown very well. Too well, perhaps. One could say that the plants have commingled nicely; from another perspective, one could say that they are overunning each other. A blackcurrant bush or bushes has swelled into a mass of unapproachable stems 10 feet deep and wide. Chives and oregano have each taken over their areas. (How much chives or oregano can you eat? I’d rather eat tomatoes.)
   Not that I’m immune to such errors. A few years ago I created a very permaculturesque planting that included elderberries, seaberries, and rugose roses almost elbow to elbow. It all looks very nice but these three shrubs all spread by suckers. I keep everything in check with elbow grease and a scythe . . . for now, but Mother Nature is relentless. Am I?
   The most productive and accessible parts of the UMass garden are the beds of kale, beets, and other vegetables — straight rows in cultivated soil. How un-permaculturalesque.
   Oh, I forgot to mention the groundnuts at UMass. Stems of those plants are twining around and overpowering others in their guild in an ever-widening circle. Even if the groundnuts could peacefully coexist with their neighbors, grubbing up the golf ball size tubers will require an inordinate amount of time and soil discombobulation.
   My memory fails me. Perhaps it was hog peanut rather than groundnut vines threatening their neighbors. Perhaps it was both plants. Hog peanut has been suggested for erosion control, and as a groundcover, a livestock forage, and a food for humans. My suggestion: Hog food. Turn some hogs loose in a patch, and they’ll fatten as they clear the ground of this pernicious weed. Does anybody have a small hog for rent?

Elderberry Wine — No, Syrup

    Elderberry looked to be one of the most successful plants in the UMass permaculture garden. It grows fast and it grows high. My two plants, now in their third year, yielded more than four gallons of berries. And harvest, last week, was quick and easy; aggressively tickling the umbels had the berries quickly filling a basket.
   Elderberries can also be recommended for their flowers and the berries’ deep, blue color. Flowers open in June to dinnerplate size umbels of small, white blossoms. They’re good for tea, fritters, or to flavor wine.
   The berries impart their good color, but little flavor, to wine, pie, and juice. (They should not be eaten uncooked or unripe.) There’s a bit of scientific evidence than an extract or syrup of the berries can help fight flu, perhaps other ailments also. I’m good at growing fruit, not cooking it, so I gave my crop to Dina Falconi who concocted a syrup using the recipe from her book Foraging & Feasting. I look forward to tasting the benefits of my horticultural and her culinary skills.
