OTHER APPROACHES TO SUSTAINABLE VEGETABLES

"Grass-fed Vegetables" With gardening activities grinding almost to a halt, I can take a breath and reflect on the past season — one of the best seasons ever. Of course, I’ll “blame” the bountifulness mostly on the weather. Maybe I’m also becoming a better gardener. (Thomas Jefferson wrote, “Though an old man, I am a young gardener.”) I wrote a couple of weeks ago about soil management here on the farmden. It’s simple and possibly sustainable. For the vegetable gardens: no digging, permanent beds, and an inch depth of homemade compost annually slathered onto those beds.…
FLOWERS ALL WINTER
Mine Aren't Frilly And now, with a bow to my feminine side, a little something about African violets, houseplants that have traditionally been thought of as old lady’s flowers. Still, I’ll admit it, I like African violets. They offer so much for what little effort I make in growing them. Mainly, what they offer is flowers, and at a time — now and throughout fall and winter — when flowers are at a premium. I have only one variety, but if I was really into African violets, I could be choosing plants with white, pink, blue, or purple flowers, or blue with white picotee, or white…
IT’S A GAS!
Last Tomatoes & Peppers Late fall, and my thoughts turn naturally to . . . ethylene! You remember ethylene from high school chemistry. A simple hydrocarbon with 2 carbon atoms double-bonded together with 2 hydrogen atoms attached to each of the carbon’s remaining two free bonds. C2H4. It’s a gas, literally, and an important industrial chemical transmuted into such products as polyethylene trash bags, PVC plumbing pipes, and polystyrene packing “peanuts.” Oh, I forgot, this is supposed to be about plants. Ethylene is synthesized in plants and is a plant hormone with — as…
VIRTUAL TRIP TO MEDITERRANEAN
Goodbye to Figs (For Now) With yellowing leaves and dropping leaves, my greenhouse figs are looking sickly. But all is well in figdom. A common misconception is that figs are tropical trees. They’re not. They’re subtropical, generally tolerating cold down to near 20°F.. And their leaves are deciduous, naturally yellowing and dropping this time of year, just like maples, ashes, and other deciduous trees. My greenhouse thermostat kicks on when the temperature inside drops to about 35°F. Daytime temperatures depend on sunlight; they might soar to 80° before awakening the exhaust fan…
THE UGLY, THE TASTY, & THE BEAUTIFUL
Close Your Eyes, If Necessary
“A crabby looking, brownish green truncated little spheroid of unsympathetic appearance.” That’s how a British writer of almost 75 years ago described one of my favorite fruits, medlar (Mespilus germanica). True, the fruit is no beauty to some eyes. To me, the fruit has an authentic, old-fashioned, unvarnished look to it, like that of a small, russeted apple whose calyx end (opposite the stem) is flared open.
Medlar is truly an old-fashioned fruit, whose popularity peaked in the Middle Ages. Chaucer mentioned it, indecorously referring to it as…
SUSTAINABLE DIRT
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,…
SWEET ANNIE AND SWEET GRAPES
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…
NUTS OVER CHESTNUTS
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.
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…
CLEAN UP, THEN SHAVE
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…
