The (Nearly) Weed-Free Garden – Podcast #30

Here’s a picture of Lee Reich’s garden:

Either he knows a lot about gardening, or he’s a whiz at Photoshop. I’m betting on the first, which is why I interviewed him for this week’s podcast, The Weed-Free Garden.

Lee has a four-part system for beating the weeds:

  •    – Don’t disturb the soil. (prevents buried weed seeds from surfacing and germinating.)
  •    – Set up permanent beds and paths. (so you won’t have to till to aerate the soil.)
  •    – Keep the soil covered at all times. (so weeds can’t get established.)
  •    – Use drip irrigation where irrigation is needed. (prevents disease in a densely planted bed, saves water, and puts the water where it’s needed: in the root zone.) Continue reading

More Space Than You Thought – Podcast 29

 

Fern Richardson grows “tons of herbs,” “tons of succulents,” lots of vegetables, and at least six trees—on a balcony. I’m not quite sure of the tree count, because after I counted to six, I’m afraid my hearing did the auditory equivalent of glazing over—I just wasn’t entirely functional for a moment there.

When she was listing them—the kumquat, the apricot, the fig, the two apple trees—I squawked “TWO?” so loudly that I had to lower the volume of that one word in the recording, to preserve my listeners’ hearing. There are two, Fern quite reasonably replied, because apple trees cross-pollinate with a nearby tree of a different variety.

I know this, of course, but still—two apple trees on a balcony? And lest you envision some Hollywood terrace big enough for a swimming pool, let me give you the exact dimensions of Fern’s garden space: four feet by ten. (4’ x 10’)

Polyculture all the Way – Podcast 27

The old kitchen garden, with its neat, straight rows of vegetables, has faced any number of challenges in recent years—raised beds, intensive gardening, square foot gardening, succession planting—all turn their backs on the conventional layout of neat rows of carrots, peas, or potatoes.

Enter polyculture, which turns its back not only on rows, but on the whole idea of a vegetable garden at all. Not that you shouldn’t grow vegetables, but in a polyculture, they’ll be mixed up together, and there may well be herbs and flowers in the mix as well.

David Deardorff and Kathryn Wadsworth have just published What’s Wrong With My Vegetable Garden?: 100% Organic Solutions for All Your Vegetables, from Artichokes to Zucchini. For them, as for many organic gardeners, half the solution lies in prevention, and a key to prevention is polyculture. When they talk about putting the right plant in the right place, they mean not just giving it the soil, light, and water that it needs, but the growing companions as well. Continue reading

Podcast #26 Minding Your Manure

The Show

The manure problems—pollution and contamination—that I reviewed in my last post occupy the first part of this podcast, and if that were all we covered, you too might be inclined to crawl under your desk and stay there.

A quick recap: Rather to the surprise of many an organic gardener, even organic manures can cause problems: phosphorus can contaminate surface water, while nitrogen can leak into ground water and can also form nitrous oxide, a greenhouse gas almost 300 times as powerful as carbon dioxide.

Podcast #24 From Seed to Seedling

The incredible thing about interviewing Judy Owsowitz is how much she knows. This is true of just about everyone I interview, and I always learn something, but in a way it’s more startling when the topic is one that I actually think I know something about, such as starting seeds and caring for the seedlings.
