Properly planning, preparing, and maintaining the vegetable garden reduces the chances for problems to develop in the garden. When vegetable problems do occur, it is important to accurately identify or diagnose them so proper control and management strategies can be implemented.

Diagnosing Problems in the Vegetable Garden

Identifying or diagnosing problems begins with asking the right questions to narrow down the list of possible problems. The following article provides some guidelines for asking these questions:

• Diagnosing Vegetable Problems (New York State Agricultural Experiment Station, Cornell University).

Some commonly found problems on commonly grown vegetables are covered in the following article:

• Troubleshooting in the Home Vegetable Garden (Cornell Cooperative Extension).

- Hint: The first section, "Main Causes of Crop Injury, Poor Growth, or Low Yield," discusses general considerations that could affect your vegetable(s). The section "Some Common Problems with Causes" is geared toward more specific common problems in the garden.

Some of the resources in the "Regional Vegetable Insect and Disease Resources" section below also have identification and diagnostic aids that may help in the diagnostic process.

Managing Insect and Disease Problems

Careful management of the vegetable garden will help eliminate many problems in the garden. See what you can do to prevent or control insects and diseases in the home vegetable garden in the following articles:

• Managing Insect Pests in Vegetable Gardens (Cornell University).

• Minimizing Diseases in Vegetable Gardens (Cornell University).

Regional Vegetable Insect and Disease Resources

Identify vegetable insect and disease problems, along with their solutions, by looking up resources that most closely match your region of the country.

• Vegetable Disease Problems by Region

Managing Animal Problems

Deer, raccoons, woodchucks, rabbits and squirrels may browse in the vegetable garden. The first line of defense against wildlife is to keep them out of the garden area. Locate the garden plot away from areas that are the home of wildlife. Fencing will restrict many mammals, but it may need to be 6 inches into the soil to deter some pests, such as woodchucks.

Commercially available products designed to deter animal pests through scent, sound, or touch, are usually only partially effective. A fence around the garden area or the presence of a cat or dog nearby may be more effective choices for control. For food safety reasons, however, pets should be kept out of the garden itself.

Animal Resources

Use the following tool to help identify which animal species is causing damage:

• Identifying the Animal Species Causing damage to Gardens, Crops and Grass (Internet Center for Wildlife Damage Management), part of the "Animal Damage ID Inspection Process."

More information about specific wildlife species can be found at eXtension's:
