In searching for information on getting rid of bugs from my vegetable garden, I came across some really valuable information from many online sources. I should start by saying that I have just started using some of these suggestions, and do not assure you 100% effectiveness, yet. That information will have to follow in a few weeks.

My search originally started by looking for chemical-free products to kill off any unwanted pests. I was quickly swayed by all of the information available about companion planting. Companion planting involves planting differing plants around the plant you wish to protect. Each pest has a plant it doesn't like, this works in our favor when we know which pest we're dealing with. It is imperative to keep the additional plants localized to the protected plant. Bugs are smart enough to go another route or even jump from plant to plant to get its fix. It's best to surround the protected plant with the deterrent plants listed. For example, to get rid of ants with aphids, plant pennyroyal and spearmint around the stalk of the protected plant. A few feet to each side will not deter the ants from going right through the middle.

Here are some simple rules to follow when protecting your vegetable garden from pests:
