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.
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…)
We’ve been intrigued lately how the practices of sustainable, organic gardening and permaculture integrate composting into their philosophies. Your friendly Planet Natural Blogger has been known to say that organic gardening and specifically composting will save the world and both those endeavors seem to prove it. Yet, both have their differences.
We won’t go into all 12 principles of permaculture here. But consider how many of them are addressed by composting (as listed in Christopher Shein’s excellent new book The Vegetable Gardner’s Guide To Permaculture): work with nature, produce no waste, use and value resources, catch and store energy. To organic gardeners, all that come together to mean one thing: improve soil conditions without harmful chemicals.
This is the time of year we’re adding grass clippings, if we have them, to our compost piles as well as vegetable scraps from our kitchens, thinnings from our garden (if we’re not eating them), and year-round items like cardboard and newspaper. The permaculturist, in an effort to diminish waste, advocates using shredded office paper and the like as a brown (carbon-heavy) material. The organic gardening purist may not want to add newspaper because of what might be in the inks, office paper because of the bleaching agents that make it white, and carboard because of the glues used to hold its corrugated surfaces together.

It’s a point we’ve made often: healthy soil is the key to organic gardening. Whether you’re growing vegetables, ornamentals, or a lush, durable lawn, the health of your soil is what makes it all possible.
Healthy soil is living soil, filled with billions of microbes and beneficial, microscopic fungi; nematodes, earthworms and other beneficial organisms. It’s alive. Frank Tozer, in The Organic Gardeners Handbook says that growing plants is the secondary activity of the organic grower. The first? Growing soil. Grow soil full of organic material from compost, full of living organisms, and the other necessary ingredients plants require, and growing gardens, without chemical fertilizers and the use of pesticides and herbicides to control problems, becomes vastly easier.

We’ve written a lot about planning your garden, which plants go where, crop rotation, companion planting, and the like. But what to do when you’re starting a garden or want to create a second (or a third) garden space? Where is the best place for your new garden to go? What factors should you consider when starting it?
Often we don’t have a choice. Our yards are small. Everything is heavily shaded except for that one spot over there. If we put the new garden right in that sunny spot in the middle of the yard, where will we play badminton on the fourth of July? Choosing where to put a garden space is a problem a lot of us don’t have.
But if we’re lucky enough to have the space where a choice is in order then it’s important we choose wisely. It’s safe to say that we already know the principles. What’s best for the plants you want to grow? Here’s a brief and most likely incomplete list of principles to consider when starting a garden. Feel free to add things we may have overlooked and other suggestions that will assure you convenience and make your plants a growing success. (more…)
Reading through Danny L. Barney’s new book Storey’s Guide To Growing Organic Orchard Fruits (Storey Publishing) not only got us to thinking about what it takes to grow apples, pears, cherries and other fruits without chemical sprays, but also, like a lot of things, made us nostalgic.
Your sentimental, fruit-crazy Planet Natural Blogger grew up on a small orchard back in Nebraska that was sprayed heavily every year. My father was in the pest control business and had access to the compounds and equipment. I remember him fogging the whole place in an effort to keep the mosquitoes and other insects down. Insects weren’t the problem, and needless to say the sprays did nothing to alleviate our real problem, blight and blemishes (and we still ended up with mosquitoes anyway). He didn’t wear a mask or respirator when doing this and neither did we. But we loved to run through the fog much to his chagrin (Note: Dad’s long gone but we’re still healthy). (more…)
There’s been a lot of talk this season about using manures in the garden, the probability of hot manures (rich in nitrogen) “burning” seedlings and squelching germination, and the fact that many commercial manures — or ones you might get from your local farmer — contain metals or toxins not suitable for organic gardens.
Your friendly Planet Natural blogger has always liked using compost to keep garden soil healthy and balanced just the way plants like it, which means most of the manure went into the compost heap. And we were happy to use it because it came from an organic goat dairy. But what about those with new gardens or those with gardens that need amending to help keep the soil at its growing best? That’s the time to fertilize.
In fact, the best time to fertilize is ahead of planting. Of course, that makes it imperative that you hold nitrogen levels down to prevent seeds from not germinating. But most good formulas come this way, so you shouldn’t have anything to worry about. You can always beef up the nitrogen (but not too much, keep it in balance and consider the special needs of different types of plants) later in the season. (more…)
