How can I tell if a chemical is okay to use in a garden?

You should first check the label of the chemical product to find out if it is safe for use in a garden. You could also contact a local garden center or your local agricultural extension office for advice on which chemicals are appropriate for use in a garden. Additionally, you may want to do some research to ensure that the chemical you are using is not hazardous to plants, animals, or the environment.
