What is the Master Gardener Program?

The WSU Master Gardener Program is a nationally recognized program that trains volunteers to serve their communities through horticultural education and outreach. Everyone with an interest in gardening and volunteering is welcome and encouraged to apply for the program. Once volunteers receive training, they provide educational information to the public in home and subsistence horticulture including vegetable and fruit gardening, lawn and landscape maintenance, composting, native plants, plant problem diagnosis, pest control and many other areas.

Need help or advice?

Master Gardeners are available throughout the year on San Juan, Orcas and Lopez islands to answer your gardening questions. Whether you have questions about your soil, have a problem with your fruit trees, or are thinking about starting a garden, volunteers will be happy to provide you with the research-based information you need. WSU Master Gardener Volunteers are available to speak to garden clubs, or at horticulture classes and workshops. They conduct diagnostic labs and tours. During the summer, WSU Master Gardeners can be found at plant clinic locations around the county.

Advice for your plant problems…

Do you have a plant problem and would like to find the answer? WSU Master Gardeners are here to help diagnose your plant problem and/or identify your weed, insect or plant. Volunteers will provide you with research-based information on how to control the problem.
