WSU 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. Master Gardener are available to speak to garden clubs, horticulture classes, and workshops, and they conduct diagnostic labs and tours.

  3. Email the form and photos to

Drop off a printed form with a sample

Frequently Asked Questions (FAQ)

What should I do if I have a general gardening question?

If you have a general gardening question, you can leave a message with the WSU Extension office. Please note that it might take us a few days to respond but a volunteer will be in touch soon!

When is the next Master Gardener Training?

We offer the Master Gardener training every other year in San Juan County. Please contact our coordinator for more information and to get on the email list.

Where can I get native plants for this area?

Native plants are often a good choice because they are adapted to our PNW soils and climate. WSU Master Gardeners hold an annual Native Plant Sale each March. Most plants are native to western Washington and are either bare-root or in small containers. For more information about the Native Plant Sale, see the Master Gardener Foundation of San Juan County website.

How do I start a worm bin?

Getting started composting with worms is easy, and anyone can do it—whether you live in an apartment, or on 10 acres. A worm bin is a great alternative to a compost pile, and food waste decomposes quickly without odors or attracting rodents. You can fill wood or plastic bins with shredded newspaper along with worms and kitchen scraps. Omit oils, meat, and citrus. Worms will eat everything else.

For more information, find informational packets at the WSU Extension Office, read the Worm Compost Fact Sheet, or make your own cheap and easy worm bin.
