Identifying problems, and then identifying the culprit, is a major step to solving the problem. Many gardeners decide to go organic, deciding against any spraying. Then when their tomato plants are chopped off by cutworms, their corn is full of worms and their hosta leaves look like swiss cheese from nightly attacks by slugs, they reverse their decision, and pull out every chemical known to man to stop their problems. But there can be a happy medium. When problems occur there are good, safe chemicals on the market, but if you choose not to use them, there are some good organic options as well.
Insect control can be a challenge.
There are numerous organic insecticides, physical barriers or traps, or beneficial insects. It always amazes me when I see a gardening show from up north, advise gardeners not to worry about bugs, when you see one, just pick it off and kill it. That may work fine in the north where there are a few bugs per year, but in Arkansas that may turn into a full time job during an average growing season. Again monitoring for problems is crucial. There are several good baits or traps on the market to help you determine the number of pests you have.
