Gardening Questions?

The WSU Master Gardener Plant Clinic and Resource Center is open March 1, through October 31, each year:

Master Gardener Volunteers and Extension Staff are here to assist you with your gardening questions and to offer research-based information to help you.

The Plant Clinic and Resource Center also has books, fact sheets, and publications on plant identification, pests and diseases, weeds, landscape trees and shrubs, perennials, grasses and ground-covers, native plants, greenhouses, plant propagation and many other horticultural topics.

At the present time, the Master Gardener Plant Clinic is operating with minimal staff and shorter hours Monday – Friday 9am-1pm.

For your convenience, we have a self service station for dropping off samples inside the Extension Office, just outside the Plant Clinic doors. The Extension Office is open from 9am- 5pm.
