At the Plant Clinic we answer a wide range of questions about home gardening. We diagnose plant problems; identify insects and plants; and answer general garden and orchard management questions.

Insect Committee
Nearly 25% of the calls to the Plant Clinic concern possible plant damage from or problems with insects and other arthropods. With over 1 million identified species of insects worldwide and an estimated 15 million possible species total, this would seem an impossible task but an analysis of Plant Clinic data for Douglas County shows that 90% of the insect questions involve only about 50 insects and spiders.
While most Master Gardeners have no problem identifying the usual bugs brought into the clinic, the job of the Insect Committee is to supply aids and books to help with this task. The committee also identifies those uncommon insects that occasionally show up. The committee meets on the first and third Monday of every month if needed.
