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.
For a lot of us, November marks the end of our outdoor gardening season. There’s still puttering to do: cleaning and oiling tools to be put away for the winter, bringing indoors any potted plants we may still have outside, trimming back and protecting roses; that kind of thing. Often we’ll wait for a sunny (relatively) warm day to do these things. But as all of us have heard said — thank-you, Coach Kruger! — it ain’t over ’til it’s over. And in gardening, that means it ain’t over until the ground freezes, no matter what the calendar says.
Leaves, turned into rich organic compost or protective mulch, are Autumn’s gift to composting.
We’ve often said that composting can save the world. Here’s one of the ways. During the fall, our yards and landscapes yield tons of refuse, much of it the form of leaves. Those leaves, bagged and placed on curb sides across the country, contribute significantly to the trash that goes into our landfills. In 2006, even after many local governments had instituted yard waste recycling programs, leaves, grass clippings and the like made up the largest component by weight of everything that went into our landfills. Grass clipping were the largest component by weight of yard waste but leaves were by far the largest component in volume. By 2013, yard waste had fallen to third, behind paper products and food waste. Progress! (more…)
Protect, nourish garden soil by growing organic, winter cover crops.
Planting cover crops — green manure — early enough in the fall has always been something of a problem for me. We all know the advantages that cover crops give our soil. They blanket it over the long winter, protecting it from erosion, keeping it from hardening and preventing the leaching of valuable nutrients by rain and snow. Their roots keep the soil aerated. They protect against the dangers of a deep freeze, thus preserving beneficial microbes and other organisms that help keep your soil healthy. They help prevent the spread of weeds. Best, cover crops add green material to the soil, material that supplies nutrients as well as nitrogen. They’re one of the most valuable tools in the organic gardener’s playbook. (more…)
Make sure your garden is ready for winter.
Putting gardens to bed in the fall is something like putting children to bed for the night. Both are multi-step processes. Kids need to change out of their clothes, bathe and/or wash their faces, brush their teeth, and might even need a bed time story. Gardens? They can be as reluctant as kids when its time to go to bed. It might take you weeks to get them there.
Properly preparing gardens for winter can have huge rewards come spring time. I’ll admit I am both reticent and lazy when it comes to tucking the garden in for the winter. But prompt and considered work this time of year means less work in the spring. And isn’t gardening a four-seasons activity? (more…)
Our most widely used herbicide is draining the life from the earth.
We’ve often argued against “biotech” or genetically modified crops and the accompanying use of glyphosate herbicide — trade name Roundup — because of its effects on human health, sustainability, and its culpability in creating a new class of glyphosate-resistant “superweeds” that are spreading across America’s farm country. Now comes word that Roundup is killing not just weeds but the very soil in which we grow our crops.
This article in The New York Times explains the negative effects glyphosate has on soil, effects that include compaction and resultant runoff, the killing of beneficial microbes and bacteria, and the exhaustion of necessary minerals and other nutrients that plants require. (more…)
How to keep weeds and invasive plants out of your organic garden.
September is here and many plants in the garden are going to seed. Some of those plant are weeds. Depending on how carefully you kept your plots and landscapes weeded this season, you may have lots or you may have few. However many weeds you have, now’s the last chance you have to get them before the cycle starts all over again next spring. Any work you do now will make your weeding easier next year.
I know, I know . . . the best and most effective weeding is done in early season when the ground is soft and the weeds are small, shallowly rooted, and vulnerable. But it’s too late for that. And next spring will be too late to stop weed seeds from spreading now. Weeding is a continuous activity in the organic garden and one’s attitude towards it has a lot to do with seeing it as a chore and impossible task or an ongoing activity that provides exercise, fresh air, and a chance to get close to one’s garden. Part of that attitude requires acceptance. You’ll never get all the weeds (or maybe you’re one of those people with small plots who will) and it’s better just to accept some. Even those herbicides we see advertised on television as giving complete control don’t get all the weeds. Just make sure the weeds you miss aren’t the most noxious or persistent. Those are the ones to concentrate on. (more…)
The growth of small farms, organic crops, and locally sourced foods.
Corporate farming has disrupted an independent economic model and a way of life that was common just a few generations ago. Things were different when America’s farming economy was based on countless small, independent producers who then sold their products at rural cooperatives or directly to markets. Today, a few large food producers including Cargill, Archer Daniels Midland, and Tyson, and a few large (mostly) chemical companies, including Dow Agro Sciences, Cargill and, yes, Monsanto, have a corner not only on our food supplies but the products used to raise them. This consolidation of our farm and food supplies creates huge problems, not just in this country, but world wide. (more…)
We all know the nutrients — nitrogen, phosphorous, potassium, magnesium, calcium, sulfur — that are important to plant health. We call them macronutrients. But there’s a whole list of plant micronutrients that are also key, in much smaller quantities, to the health of your plants. These micronutrients — boron, iron, zinc and others — not only assure healthy growth, they help your gardens fight off pests and diseases.
The best long term way to keep your garden soil rich with the micronutrients it needs is by adding compost. The living things that go into compost — grass clippings, leaves, plants trimmings — already contain various amounts of micronutrients. Their presence in your compost guarantees that you’re returning those micronutrients to the soil.
But what if you can tell (PDF), because of yellow leaves or other signs of weakness (or from you extension services soil test), that your soil is deficient in micronutrients? Your plants are well on their way and it’s too late to effectively amend the soil. What can be done to give them a quick boost full of the micronutrients they need? (more…)
Weeding, watering, and organic pest control in the summer time.
It’s July and, as the song goes, the living is easy. Sure there are little chores to be done — watering, of course; and weeding — but mostly this is an expectant time with bountiful harvest of greens, peas (if you live where it’s not too hot), and fast growing root vegetables. Summer squash are in blossom and maybe setting fruit, corn is knee-high and higher, and winter squash, cucumbers and other vine crops are showing some muscle and starting to take over. There’s the first tomato blossom and is that the first tiny bean forming among all those blossoms?
It’s a good week to spend time with your garden doing nothing but taking stock. How is your garden plan looking now that things are well on their way? What pest problems are you having? How does the weather look for the rest of the month? Mostly, we just like to sit back and look at the fruits of our work. Things are still neat and orderly, everything is robust and green. And then we start thinking deeper (gardens will do that to you). Where did the craft of doing this come into our lives? How is it that with each passing year we learn more and more about raising vegetables? How well are we doing passing our knowledge to children and friends? And how important are those friends and children to what we do and learn? (more…)
This year’s dead zone in the Gulf of Mexico, usually around 6,000 to 7,000 square miles, might well be the largest in history. The culprit? Heavy rains and flooding in the Midwest. All that runoff from the breadbasket will make its way downstream carrying copious amounts of agricultural fertilizer runoff into the Gulf. Time magazine has the story.
The Gulf dead zone, second largest in the world, is composed of oxygen-depleted water that does not support life. The process by which it forms is known as “hypoxia.” Basically, the process starts with nitrogen and phosphorous- based fertilizers being swept in quantity through the Mississippi River basin and into the Gulf at the Louisiana Delta. The fertilizer fuels the growth of algae which eventually dies or is eaten by zooplankton. Bacteria feed on the mass of dead algae and the zooplankton’s feces, exhausting the water’s oxygen as they do. (more…)
