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. Click on the information and news below to learn about soil health and what can be done to improve it.
Healthy soil is the basis of healthy plants and a healthy environment. When garden soil is in good shape there is less need for fertilizers or pesticides. As author and respected gardener Frank Tozer writes, “When building soil you not only improve your plants health, but you can also improve your own.”
Organic soil is rich in humus, the end result of decaying materials such as leaves, grass clippings and compost. It holds moisture, but drains well. Good organic garden soil is loose and fluffy — filled with air that plant roots need — and it has plenty of minerals essential for vigorous plant growth. It is alive with living organisms — from earthworms to fungi and bacteria — that help maintain the quality of the soil. Proper pH is also an essential characteristic of healthy soil. (more…)
Bagged soils can contain herbicides, gnats, and other unsavory problems.
Stories about compost possibly contaminated with heavy metals from sewage waste and disastrous herbicides turning up in potting soil aren’t new. In 2010, the University of Maryland Extension put out a “Gardener’s Alert! Beware of Herbicide-Contaminated Compost and Manure.” The Ohio State University Extension put out a fact sheet on one persistent pesticide showing up in compost that kills off tomato, eggplant and other nightshade family vegetables as well as beans and sunflower.
But it seems more recently that gardeners are starting to pay attention to other problems that come with mass-produced, commercial potting soils and compost: the importation of pests and disease into your garden or indoor grow space. (more…)
No-till, reduced pesticide and herbicide, cover crop farming methods on the grow.
Organic gardening practice that emphasizes soil quality in our backyard vegetable patch and landscape is one thing. Improving our nation’s farm soils, acre by acre, is another.
So it was with a smile that your cheerful Planet Natural blogger ran across this announcement of the 2015 Tri-Basin Natural Resources District Soil Conservation Award from south-central Nebraska.
The winner, Greg Linder of Loomis, Nebraska, is something of an American inspiration for both the generations of farming his family represents, as well as his efforts to protect two of his county’s greatest resources: its soil and water. It’s worth reading the whole story. (more…)
Gardening with nature in mind’s new buzz word.
What is “rewilding?” Valerie Easton’s Natural Gardener column in a recent issue of The Seattle Times‘ Pacific NW Sunday magazine puts perspective to the Johnny-come-lately gardening term. The piece, called “In Harmony With Nature,” is sort of a celebration of rewilding which, she notes, only first appeared in the dictionary in 2011. She says, “I like to think that in the gardenesque sense of the word, rewilding represents a desire to meddle less and celebrate nature more.”
Less meddling sounds like less work to me. Needles to say, your mostly-industrious Planet Natural blogger likes the idea of less work. (more…)
…and other garden tasks we should have done this past year.
Your friendly Planet Natural blogger is not ready to start making New Year’s gardening resolutions just yet. But with the new year in mind and our ongoing resolve to be a better organic gardener year after year, we’ve gone back through our gardening journal and found problems that we might have solved, if only … well, you know the rest.
So, in the interest of growing better organically, here’s some things we could have done better last growing season. (more…)
The world is learning the value of improving soils and growing without chemicals.
As organic gardeners, we’ve long known the value of maintaining healthy soil. It’s the key to successful growing and the means to avoiding the use of harmful chemical fertilizers and pesticides. Keeping our garden soil in top condition by adding plenty of compost and other organic matter, using cover crops and mulch to protect it, and doing all we can to promote healthy microbes, fungi, and other living organisms that promote the restoration of nutrients, goes a long way in assuring successful gardening without environmental harm.
Organic gardeners know that soil is alive and must be treated as a living organism. Treating it with harmful chemicals and poisons, otherwise known as herbicides and pesticides, takes the life (and therefore the productivity) from the dirt in which our crops grow. (more…)
Hint: It’s the slime.
Maybe your friendly Planet Natural blogger ate too much pie. But during a free hour in our recently passed holiday, he sat quietly — no football, no television — and thought about his garden and the ongoing cold snap. Then, as Dr. Ray Stantz (Dan Akyroyd) says in the film Ghostbusters, it just popped in there. What happens to worms in winter?
Now every gardener loves earthworms. They’re tunneling helps keep your soil porous and conduct moisture. They feed on decaying matter, leaves and other plant matter, as well as fungi, bacteria and nematodes, then excretes them as vermicompost or worm castings, one of the most potent soil amendments there is. As the Colorado State University extension department puts it, both the structure and fertility of your garden soil are in the care of earthworms. (more…)
Short-takes on natural gardening topics we’re following.
As we enter a new month, your (mostly) timely, inquisitive Planet Natural blogger takes a minute to catch up on a handful of issues.
–Oregon GMO Labeling Vote: The final vote count is in and Oregon Initiative 92 to label products that include genetically modified ingredients is so close that a recount, scheduled to start December 2, has been called. Initial reports from The Oregonian on the day after the election had the measure failing narrowly. That margin — 812 votes or 0.05% of the total — turned out to be closer than imagined and now the race is too close to call. This is encouraging news, no matter what the final tally shows. Corporate forces, as usual in these votes, vastly outspent the pro-labeling side and the closeness of the Oregon vote suggests that they’ll even have to spend more to spread their misinformation.

Autumn’s the time to soil test, clean out pests, and add amendments.
You’ve heard it said a thousand times, many of those times on these very pages: the key to a great garden is great soil. Working the dirt in autumn can be a relaxed, pleasant experience, not as intense or rushed as the heavy-turning, fine-tuning soil preparation of springtime. The things you do now, in the days of fall, go along way to ensuring a quick, healthy start come next growing season.
You’ve cleaned out this year’s garden (or are about to), disposed of any plant debris that may harbor disease or insect pests and composted the rest. Here’s what we like to do ahead of putting our plot down for the winter under a protective blanket of mulch. (more…)
Documentary film on master gardener Paul Gautschi’s got the spirit.
In the battle over what constitutes healthy food, it’s no longer surprising to see the documentary film as an effective weapon, most often deployed on the side against corporate agriculture and for public health and well-being. Films including Food Inc (watch it here), 2004’s Supersize Me, a month of nothing but McDonald’s, and most recently Fed Up which implicates a government-corporate collaboration to promote and reward refined sugar, are all convincing, visual arguments of the dangers of the commercial food culture.
Broadly about food, these films are specifically about processed foods, organic and locally raised farming, the health consequences of certain refined foods and fast-food diets. Related films include GMO/OMG , a study of the corporate takeover of farming through seed production, GMOs, and related pesticides. Now even documentaries championing organic gardening are getting into the act. (more…)
Solar-powered monitoring and control of garden conditions holds promise.
Developing and using new technology has been part of gardening since ancient peoples first started fashioning stone tools for digging. Nearly all advances in agricultural development, from the first use of antlers as a hoe to the gas-powered roto-tiller (and its big brother, the tractor and plow) have come from technological development. Not all of them have necessarily been good. But most of them are done in the name of advancing the science and craft of food production (some seem done purely for selfish profit-motives).
In terms of home gardening, technology hasn’t really changed that much since our grandparent’s days. And most of the recent advancements, things like electronic soil testers and digital moisture meters are useful advances that help make it easier to gather the information we need for best growing conditions.
