growing potatoes organically: when and how to plant, hill and harvest

Autumn sunshine sets off the traffic lights in the vegetable plot. A low angle for the rays of sunshine creates an extra opportunity to appreciate this vegetable. I like the leaf texture and think Chard can look so colourful that I will grow some amongst the flowers for next year.

Gardening in the winter is somewhat challenging but doable. Many of the greens, some of the root vegetables, and herbs can be planted in the fall and will grow through the winter months. The saying is that greens are better after a frost.

And though most leaves are green—why are some not green at all, or at certain times of year?The new book, “How Plants Work: The Science Behind the Amazing Things Plants Do” answers those questions and more. (Enter to win a copy at the bottom of the page.)Its author, Linda Chalker Scott, joined me on the public radio show and podcast to explain. Linda is an Extension Urban Horticulturist with Washington State University, a

I PUT MY BEANS UP ON A PEDESTAL because they are one of the crops that’s finally producing here in the Year of Big Rains. In fact, I just planted another whole row of bush beans, along with more collards and kale, among many things. Welcome to Week 3 of the cross-blog Summer Fest 2009: Beans and Greens Week, a perfect time (if you hurry) to fine-tune the vegetable garden and eke out some produce for late summer, fall—and beyond.

I invited my favorite fruit expert, Lee Reich, author of many exceptional garden books, including “Grow Fruit Naturally” and “Weedless Gardening” and “The Pruning Book,” to come talk figs on my public-radio show and podcast. (I’m giving away a copy of “Grow Fruit Naturally;” enter by commenting in the box at the very bottom of the page.)I often refer to Lee as “the unusual fruit guy,” because one of his first books I read was “Uncommon Fruits Worthy of Attention.” Lee lives with blueberries and paw paws and medlars and kiwis and of course figs and more not far from me, across the Hudson in New Paltz, New York, on what he calls his farm-den (as in half-farm, half-garden) loaded with unusual fruits.Learn wh

I PROMISED I WOULDN’T ADD EVEN AN EXTRA TRIP TO THE CURB WITH THE TRASH to my schedule, with all the mowing I have to do, but (big surprise) I layered on a couple of events, and I want to make sure you know about them, in case you are in the Hudson Valley/Berkshires vicinity this summer. Another container-gardening class, a 365-day garden lecture with an extra focus on water gardening and the frogboys, and a tour here in August (that last one you already might know about). Details, details:Sunday July 12, Containing Exuberance, container-gardening workshop, with Bob Hyland at Loomis Creek Nursery, near Hudson, New York, 11 AM to 1 PM, $5.

ONE SQUASH SLEPT ON THE WINDOWSILL, another in the cabinet beneath the sink. Both stayed firm (and presumably delicious) all winter long, and then some—far into the next year. Lia Babitch and Ian Robb, co-managers of Turtle Tree Seed in Copake, New York, may store their ‘Butternut’ differently, but the greater mission they’re part of is the same: to offer biodynamic, open-pollinated seed to gardeners and farmers that’s been selected to be the very best it can…which if you’re a winter squash means sticking around a good long while. Meet these gifted gardeners and more of their very special seed varieties.

I just call them all fancy-leaf begonias, but they divide into several structural groups:Fibrous-rooted ones have cane-like stems and often wing-like leaves. Rhizomatous types grow from fleshy, caterpillar-like structures inclined to spread over the pot lips or even stand upward. The extra-flashy Rex begonias, which are a little trickier if you get too cool or too hot since they may defoliate in protest, are rhizomatous. I fail with them; my conditions are not to their liking. There are also semi-tuberous and tuberous begonias, with swollen bases, but my collection doesn’t include any

Its native range, says the Lady Bird Johnson Wildflower Center, is New York and southern Ontario to Wisconsin, and northeast Iowa to Maryland, also appearing in the mountains from Georgia to Tennessee.  Depending whom you ask, twinleaf is hardy in Zone 4 or 5 to 7 or 8.The New England Wildflower Society’s Garden in the Woods, in Framingham, Massachusetts, was the first place I saw it in profusion, though it is apparently not technically a

‘HALLELUJAH, the garden saved me,” I said, and also, “What’s not to love about a frog?” Those Margaret-isms are among the snippets from my recent appearance on “The Leonard Lopate Show” on WNYC, the New York NPR affiliate I have listened to daily my entire adult life, and a fun Q&A interview in the latest issue of “Folk” magazine. Listen to the Lopate segment, and read the “Folk” piece by Andrew Ritchie (pdf format, page 18 onward).

I say “beyond” because some of those seeds came with Rowen from the colder, wetter Northeast, her “living, breathing relatives that want to live and grow with the earth, she says,” just as she does, “witnesses to the past” that tell stories that might otherwise be lost–stories she has dedicated herself to keeping alive. Like Rowen, the seeds have adapted to their new home, and thrived–including colorful corns for many distinct purposes both cultural and culinary.Rowen (above, braiding corn), who was elected in 2014 to the board of Seed Savers Exchange, is also co-author of the handbook, “Breeding Organic Vegetables: A Step by Step Guide for Growers” (pdf). We spoke on my public-radio show and podcast about curating Native American seeds; about the benefits of polyculture (Rowen adds
