Soil Health

Experienced growers know that a beautiful, sustainable garden starts with living, healthy soil. Most plants thrive in well-drained, slightly acidic, soils that are rich in organic matter. The challenge, however, is that most of the world’s soils do not exist this way and they must be balanced, or amended, to provide the conditions necessary for robust plant growth.

Fall Garden Cleanup

Garden Clean UpStop Next Season’s Plant Disease… Now!

Of all the mistakes I’ve made growing vegetables — and I’ve made plenty — the biggest (or right up there) has to do with not taking the time for a good fall garden cleanup. I can barely bring myself to tell you.

One year, like most years, a fall frost hit the garden and I didn’t bother to get it covered. It withered squash vines and wilted the late plantings of lettuce and spinach. I should have been out there right away, removing all the dead vines, pulling the spinach (some of the lettuce made it back) and not given disease a chance to get a hold in the weakened plants. But I didn’t. And then, after a wet snow, I just let it all go, not putting the garden to bed until well into November. I didn’t know it yet, but by then my lack of action guaranteed that my spinach and chard crops for the next year would be compromised and keeping my squash vines growing would become a battle.

Worms In the Garden

Garden WormsEveryone knows how great worms are for the garden. They increase your soil’s porous qualities by tunneling, they cluster around decaying matter consuming fungi, bacteria, and nematodes and excreting them as vermicompost or worm castings, one of the most potent soil amendments there is. You’ve gone to great lengths to attract earthworms to your garden by adding compost and other organic matter to your soil or maybe you purchased worms to add. (Garden worms are different than composting worms. If you do have a source of garden worms, make sure your soil is “worm-ready” with plenty of organic material or you’ll lose them). But what happens to worms in the garden as soils dry?

Worms, of course, need adequate moisture to survive. You’ve probably used mulch and kept your garden soil moist enough to sustain them. But what about your lawn, now that it’s dormant, and you’re doing what you can to save water? What about the worms? (more…)

Food Pathogens: Let’s Get Dirty!

Organic SoilOrganic gardeners know that a little dirt never hurt anyone. Of course, it’s a different story if the dirt your vegetables grow in contains herbicides and pesticides. Now Jeff D. Leach, in this op-ed piece in The New York Times argues that a little dirt is crucial to our well-being.

Leach is the director of the Paleobiotics Lab in New Orleans. He’s something of an anthropologist of human biology. His take in this article and others is that our fear of food pathogens has led to a sanitized diet that no longer provides us the beneficial microbes that fought off the diseases borne by the contamination found in industrial agriculture. “Increasing evidence suggests that the alarming rise in allergic and autoimmune disorders during the past few decades is at least partly attributable to our lack of exposure to microorganisms that once covered our food and us,” Leach writes. He goes on to suggest that “reintroducing some of the organisms from the mud and water of our natural world would help avoid an overreaction of an otherwise healthy immune response that results in such chronic diseases as Type 1 diabetes, inflammatory bowel disease, multiple sclerosis and a host of allergic disorders.” (more…)

Planting Time and Soil Readiness

Planting TimeHow is planting time like opening Christmas presents? There’s a huge temptation to get started days too early. After a long winter, after planning your garden and ordering seeds, we’re all anxious — with visions of sweet corn, squash and greens dancing in our heads — to get in there and start working the soil. Let’s tear the ribbons and the paper off and get those seeds and plants in the ground! For gardeners, the days ahead of spring planting are just as difficult as the day’s before the holiday are for children… and equally filled with anticipation.

But when it comes to planting, it’s best to be patient. Is your soil ready? In other words, is it “friable”? Several factors come into play but for established gardens with previously prepared soil, there are only two: temperature and moisture content. Here’s a list of minimum, maximum and optimal soil temperatures for common vegetables. (more…)
