Pests & Diseases

Holes in a leaf, a dusty coating or a collapsed seedling all call for a closer look. This collection covers vegetable garden pests and common plant problems, helping you find the article that matches what you are seeing. Start with identification before choosing a response: similar symptoms can have different causes.

For visible visitors, explore the guides to aphids, spider mites and tomato hornworms. Other articles cover slugs, snails and larger animals such as deer and rabbits. The disease guides discuss powdery mildew and damping off. Blossom-end rot is included as a common diagnostic problem, although it is a physiological disorder rather than an infectious disease.

You will also find introductions to beneficial insects, trap crops and biological controls. Use these to consider the whole growing space alongside the affected plant. The most useful next step may be a change in your garden routine or a physical barrier; it depends on the problem you identify.
