Rotating Crops in Vegetable Gardens

Q. I understand rotating crops in a vegetable garden can help cut down on insect and disease problems. Should I apply this method to my small backyard vegetable plot?

A. Many insects and diseases attack plants within the same family. If you have had problems with a particular pest or disease, try planting vegetables from another family in that section of your garden. Veteran vegetable gardeners will often rotate their crop plantings every two years to safeguard against pest problems.
