Garden Pests & Insects

coreopsis001-230x153When pests or disease attack there's always a reason.

Perhaps the plants are unhealthy due to irregular watering causing the soil to become very wet or dry.

Excessive cold, heat, drought, sun, drafts, overcrowding, virus and soil deficiencies are also frequent causes of plant disease.

Or the problem may be a seasonal one completely out of the gardeners control. Use each little plant "crisis" to learn more about your garden.
