ROOTS. They’re the engine of the plant, but remain mostly unseen—unless something’s being added to the garden or dug up, when we might catch a quick peek. Gardeners make some assumptions about that unseen system, imagining that it’s a particular width and depth, and watering and applying mulches accordingly to a particular “zone” we think they inhabit. Though we’ve probably never seen living evidence, we refer to some plants as “shallow rooted” or “tap-rooted,” as if we had.
How accurate are we?
To say Robert Kourik is a student of roots would be an understatement, as they have fascinated him for decades. Robert is the author of 15 books–including classic ones on edible landscaping and drip irrigation.
His latest is “Understanding Roots,” which builds on an earlier volume with more looks at what’s going on down there, and more answers to what gardeners should be doing to help. Robert lives and landscapes in Northern California, in Wine Country, where roots and every other part of the plants have been getting quite the test from prolonged, extreme drought.
I asked Robert to take us below the surface on my public-radio show and podcast. (Listen in using the player below, or at this link, or read along—or both. It’s the August 31, 2015 show.) Did you know that a tree’s roots can extend to five times the canopy’s width, or that a carrot’s may go down 4 (or even 7) feet? Or where to water to keep mature trees growing adjacent to once-irrigated lawns alive? (Hint: The sweet spot is located nowhere even remotely near the trunk.)

Every kitchen needs good storage, but not every kitchen has good storage. Some are small and need a lot of hacks to find a spot for everything. Some can be the right size but with not enough cabinet or drawer space. And others are just not using their storage potential fully, like this kitchen in San Rafael, California.

Nothing says Christmas more than a poinsettia (Euphorbia pulcherrima). Did you know that December 12th is known as National Poinsettia Day? Plant breeders have developed a wide range of colors in hues of white, purple, orange, and pink, but red poinsettias continue to be the most traditional color of the holiday season.
The backstory: About 20 years ago my longtime friend and fellow garden writer Ken Druse and I were working on a book about native plants, called “The Natural Habitat Garden,” and I joined Ken as he traveled around the country photographing natives, in nature and in gardens.One of our wildest stops was up in Sebastopol, California, at California Carnivores, which has been open and dedicated to cultivating these dramatics plants–including various native American species–since 1989. (A highly recommended destination if you are near San Francisco.) In 1998, Peter wrote “The Savage Garden,” but a lot has changed in carnivores in 15 years since the first edition–and even more so in the 40 years D’Am
SOUTHERN CALIFORNIA-based but Southeast-bred Kevin West strikes me at once as a very modern and also a very old-fashioned guy–a great combination to my mind. Quotes from the classical Roman poet Virgil open the chapters in his book, “Saving the Season: A Cook’s Guide to Home Canning, Pickling and Preserving,” which is also loaded with old-fashioned fruits he hopes we haven’t forgotten about.
Four Winds Growers was founded around the idea of developing and promoting dwarf varieties of citrus to fit the scale of the new-home boom in post-war California and beyond–including on all those patios, and also in pots as the container-gardening trend began to take hold. Four Winds remains a family business, and a multi-generational one. It was taken over by the founder’s son, who ran it from the early 1950s until recently, when his son took charge, along with his daughter; her husband, and a grandson.In his own home garden, Four Winds marketing director Ed Laivo has potted citrus that he has been growing for “upwards of 25 or even 30 years.” He joined me on the radio and podcast to share his tips on container growing and pest control. (The transcript of the Nov. 3, 2014 show is below.)citrus-growing q&a with e
THE ADVENTURE IN Mollie Katzen’s “The Heart of the Plate: Vegetarian Recipes for a New Generation,” begins even before the first recipe page. It starts in the delicious, intimate endpapers—which came from illustrated journals that the author has been keeping since she was a teenager, which were also the origin of her beloved, bestselling “Moosewood Cookbook.” The musings (that’s one in the photo above), in drawings and hand-lettered words, speak to how Mollie—a keen gardener, and the guest on my latest radio show—approaches food today. Learn how she suggests we re-define “vegetarian;” how she “paints [her] rice,” and makes her simplest, most delicious tomato sauce. And maybe win her newest book, too.
Carol, who was a longtime educator at the New York Botanical Garden and also worked for the Nature Conservancy, has looked beyond the obvious beauty of native plants and studied their life histories, lore, and even cultural uses. I knew she’d be able to answer my questions:our spring-wildflower q&aQ. I have easily and fairly quickly propagated a good number of wakerobin or Trillium erectum asexually (by division, as in the photo above) from three lonely refugees I found under my front porch 25-plus years ago. Some of the plants self-sowing, too now, Carol. How does the reproductive life cycle of a Trillium work?A. Trilliums are a favorite of many wildflower fanciers, so much so that in Europe, where there are no native trilliums, they are sometimes stolen from botanical-garden dis
Some background: The Stella Natura calendar has been published since 1978 by Camphill Village, Kimberton Hills, in Pennsylvania, and edited by Sherry Wildfeuer. Turtle Tree Seed, where Lia is co-manager, is located at another Camphill Village, in Copake, New York. Camphill Village is a biodynamic intentional community engaged in farming, gardening and handcrafting, that includes adults with developmental disabilities; a portion of each calendar sale goes to support Camphill.The 40-page Stella Natura calendar includes astronomy basics, a constellation chart, and many philosophical articles—besides the calendar itself. But it’s not a “calendar” such as you might pencil in your dentist appointment or kids’ soccer practice on; it’s a reference guide and tool (that’s a page from a recent edition, above). How it works is ex
It begins with a dedication that includes these words:“…to everyone who tears up their front yard to plant big chaotic wildflower gardens, to farmers who think hedgerows and wildflower field borders are just as important as crops, to urban planners and landscapers wh
