The WSU Skagit County Master Gardeners host weekly Diagnostic Plant Clinics in Anacortes and Burlington to diagnose plant problems and provide assistance with plants, trees, landscaping and gardens including pest and disease identification.  There are also monthly Ask a Master Gardener Booths at the Mount Vernon, Sedro-Woolley and Concrete Farmers Markets to provide general assistance with plants, trees, landscaping, and gardens.

Plant Disease Samples

Collecting and Packaging

Please submit as much of the plant as possible, including roots. Samples should include both the affected and healthy tissues so a comparison with the “normal” plant is possible. Do not send specimens that are completely dead, dried or rotted.  Digital photos of the whole plant are also helpful.

Vegetables, Bulbs and Annuals: Send entire affected plant, including roots.

Shrubs, Trees: Send both healthy and affected tissues. Include at least one specimen showing margin between healthy and diseased tissues.

Turfgrass: Send 4″ squares including roots and soil. Take samples at the edge of affected areas and include both healthy and affected grass. For best results, send samples representing healthy, slightly affected, and severely affected areas of lawn.

Insect Samples

Collecting and Packaging

Butterflies, moths and bees should be stored in a clear vial or other glass container.

DO NOT MAIL IN LIVE INSECTS or bring in badly damaged specimens.

Plant/Weed ID Samples

Collecting and Packaging

Samples for Plant and Weed ID must be alive, fresh, and undamaged. They should include leaves, buds, stems, flowers, roots, and fruits/seeds or as many of these features as possible. A single leaf is not enough!
