With the growing evidence that chemical pesticides are harmful to human health, many gardeners are looking for smart, organic solutions for pest control. Most problem pests can be controlled naturally, eliminating the need for toxic pesticides or harmful chemicals. We provide the information – and experience – to help you maintain a beautiful, chemical-free yard and garden that’s healthy for you, your family and the environment.
We’ve all heard of the benefits of crop rotation in large scale agriculture. And we all know that those benefits can transfer to our home vegetable gardens. Even the smallest of gardens can benefit from crop rotation, even if crops are only moved a few feet each year. Crop rotation is especially important to the organic grower because it precludes many of the problems that lead to the use of chemical pesticides and herbicides.
Exactly what are the benefits? Rotating crops is especially critical to preventing disease from getting a foot hold on certain vegetables you might plant. The bacteria and spores that attack specific plants can survive winters and infect those plants again the following year. (more…)
Your friendly Planet Natural blogger doesn’t like to think of himself as the cynical sort. But then you read something in the news and can’t help but shake your head. It seems that the Bayer CropScience corporation, the manufacturer of neonicotinoids, a type of pesticide that’s been implicated in the colony collapse disorder that’s decimating bee populations around the globe, has taken it on themselves to find the “real” culprit in bee decline. And what have they come with? It’s the varroa mite!
While the mite has long been a foe of bees and beekeepers, its presence doesn’t explain the extreme decline that bee colonies have suffered in the last several years. (more…)
For years, The Gardener’s Guide To Common Sense Pest Control was the go-to book on how to control harmful insects in our trees, yards, and gardens without the use of dangerous chemicals. Inspired, as the authors tell us, by the publication of Rachel Carson’s now-classic Silent Spring in 1962, it sought ways to control harmful weeds and insects naturally as well as effectively.
The Gardener’s Guide operated from two perspectives: that chlorinated hydrocarbon insecticides were dangerous to humans and the environment, and that they encouraged “the rapid growth of insect resistance.” In other words, not only were pesticides harmful, they were over a short time, ineffective.

Bats get a bum deal. Thought of as blood suckers and destroyers of fruit, bats are seen as frightening pests when in fact almost all are beneficial. Those blood sucking bats? Out of some 1,000 species only three actually take blood from mammals. And those live only in the Central American tropics. Most of the fruit bats live in the tropics as well. The bats, like the tiny Indiana bat that populates most of the midwest and east? They’re not blood suckers. They’re bug suckers. Over 70% of all bats — and more in the U.S. — are insectivores.
A single brown bat can eat between 600 and 1,000 flying insects in an hour, some 5,000 in a single night. (more…)
The effects of chemical spraying on the environment runs deep.
We’ve already mentioned the fine documentary released early this summer More Than Honey, a film that looks at the behavior of bees as well as issues and consequences behind colony collapse disorder that’s sweeping the world. As the movie states, bee activity is responsible for a third of the food we eat. Losing them would have impacts well beyond the loss of some fruit. It could mean a complete change in the way we live. The movie shows us an example of a place where bees have already vanished and the consequences that followed.
The place is China. Seems that Mao Tzedog before his death in 1976 decided that a plague of sparrows was putting a large dent in grain production. (more…)
Organic tomato pest control means keeping a sharp eye.
A friend, an avid organic tomato grower, has started her harvest and you know what that means. Tomato Festival! The festival usually runs from the first weeks of August right up to the first frost (at which point it becomes Green Tomato Festival or the Wait-Until-These-Tomatoes-In-the-Windowsill- Ripen Fest).
The event, held in kitchens around the country, is an unofficial celebration of one of our most cherished home-gardening products. Our friend grows heirlooms and so far this year has a bounty crop of golden jubilee, a juicy, subtly flavored orange tomato, as well as big, bold brandywines, and a few unusual, tremendously sweet, strangely colored chocolate stripes. (more…)
Is it still possible to take bees for granted? Since the general population learned about colony collapse disorder, the mysterious effect that has destroyed a large percentage of the world’s pollinators in a 2007 broadcast of CBS’s 60 Minutes and the publicity in its wake, people have come to appreciate bees for the critical work they do. Before, when someone was asked to think of the first word that comes to mind when they hear “bee,” they might have said “sting” or “honey.” Now they just might say “food” or “survival.”
That’s our survival, not just theirs. (more…)
How to control garden pests with safe, effective organic sprays.
No matter how carefully you control growing conditions with healthy soil and proper watering, no matter how well-thought out your integrated pest management system, no matter how lucky you’ve been in the past, sometimes a pest problem arises in your garden that requires spraying the little buggers. What you spray and how you spray can make all the difference.
Most organic gardeners prefer sprays that break down quickly in the environment or opt for home made remedies that make the plant unpalatable or difficult for the insects to populate. These organic sprays are often made of garlic, cayenne and other peppers, as well as strong scented herbs. The idea is to confuse the insect’s sense of smell (which is often located in their feet) and make them think they are where they don’t want to be. They’re often the organic gardeners first line of defense when pests are spotted. (more…)
An article in The New York Times seems to celebrate weeds: their hardiness, their adaptability, their ability to quickly evolve. It’s overall theme? In the battle between weeds and chemical herbicides, weeds eventually and always win. And while it takes some reading between the lines, the article also draws conclusions that organic gardeners have known all along. One… herbicides can be dangerous. Two… a variety of techniques, many of them organic, are needed to actually reduce crop losses caused by weeds.
So why use herbicides? Their development (PDF) was thought to be a tremendous breakthrough. As far back as Roman times farmers spread salt on their fields to destroy their enemies’ crops. Modern weed killers were introduced during World War II and their use skyrocketed after that. Chemical companies soon learned that herbicides meant big money. But almost as quickly, weeds began to develop resistance to the chemicals. Today, it’s estimated that at least 217 varieties of weeds have developed resistance (follow the link to see a frightening photo of giant ragweed taking over a field of Roundup resistant corn).

Dealing with melon pests and disease problems… organically.
After our last column, a friend pointed out that she didn’t have trouble getting melons to pollinate. Her problem was with blights and mildew. It’s true that melons are a bit difficult to grow because of their susceptibility to molds and certain insects, especially when you’re trying to grow them in cooler, damp climates. Any trouble growing melons is well worth it once they reach the table. The cantaloupes, watermelons and other melons now coming into our stores from warmer climates just don’t hold a candle to a juicy, sweet, homegrown melon.
Finding the proper natural or organic cures for these melon problems can be difficult. Mulching is great for issues caused by uneven watering. But mulch can provide places for pests including squash bugs and cucumber beetles to lay eggs. These pesky critters not only consume melon plants but spread disease and wilt. Melon leaves can be burned by insecticidal soap and liquid copper sprays, two common, organic-approved solutions for bugs and mildew. They should only be used in the most diluted form possible. Other problem solvers — like using row covers to shield plants from insects — are great ideas until you need the help of pollinators. Any successful melon growing regimen begins even before you start them in your garden. (more…)
