There are a lot of easy and effective ways to eliminate weeds and pests from your garden without the use of commercial pesticides. Most of these methods have been used for decades by traditional farmers with success.

But first, an overview on why the commercial options should be avoided:

The number one selling herbicide, or weed-killer, is Roundup. Roundup is produced by the U.S. company Monsanto and contains the active ingredient glyphosate. In the US, 5-8 million pounds are used every year on lawns and yards and 85-90 million pounds are used annually in US agriculture. Glyphosate kills plants by interfering with the synthesis of the amino acids phenylalanine, tyrosine and tryptophan.  Glyphosate has been in the legal and environmental spotlight since it was first introduced, with reports going back and forth between environmental groups and government groups claiming it is safe. Currently, the U.S. EPA classifies glyphosate as relatively safe when exposed to small amounts. However, researchers suggested glyphosate exposure possibly increases the risk for developing some types of cancer, but definitive conclusions could not be attained due to small sample sizes and confounding factors. The bottom line is, there is a lot of money that is being made by large corporations like Monsanto from Roundup sales. They would lose tremendous amounts of money, if it were proven that Roundup was unsafe or if it was banned from use. Simply stated, why take the risk of possible toxic exposure from these synthetic chemicals, when you can use nature’s time-tested systems to reduce unnecessary weed growth and unwanted pests.

Green Alternatives Learned From a Long-Time Backyard Gardener:

1. The best alternative to synthetic pest and weed chemicals is good compost. If the garden has rich soil with recycled organic matter the plants can resist disease and insects better.
2. Copper collars (snail bar copper barriers) work great to keep snails from eating young plants without using snailbait. Copper collars create an electrolytic effect that repels them when they touch it. A reaction between their slimy secretion and the copper causes the shock. No electricity is required. Encircle these strips around trees or put as a barrier around garden beds.
3. Tanglefoot barriers work well to keep ants and aphids out of fruit trees. Soap can also be used as an effective all-purpose pesticide, just make sure it is a natural soap and not a detergent.
4. Try not to kill spiders, even in your house. Spiders are voracious insect eaters. Part of having a healthy garden without pesticides, means that the “good” bugs and lizards etc.. will take up residence and keep the “bad” bugs down. That can be hard sometimes to appreciate, but it is nature’s systems working. However, Buying beneficial insects doesn’t work, they usually fly away.
5. A whole other area that is valuable is companion planting, and another is planting some crops just because they attract beneficial insects, and birds. (Follow-up post on this soon!)
