MG 7Master Gardener Plant clinics are opportunities for members of the public to get help solving gardening problems, or finding out about the latest sustainable garden practices. If you would like a plant or insect identified or a disease diagnosed, please bring as much information to the plant clinic as possible, including plant samples or photographs.

Submit questions online or in person.

In person:

In person Master Gardener Plant Clinics are closed for the season. Please submit questions via email (information below).

The Port Angeles plant clinic, located in the lobby of the historic Clallam County Courthouse in front of the WSU Clallam County Extension Office, typically runs from March through October of each year. The Saturday Sequim plant clinic, located at the Woodcock Demonstration Garden, 2711 Woodcock Road in Sequim, is typically open from May through September. We hope that both clinics will be open for full hours starting again in 2022.


You can submit your plant and garden questions to Master Gardener clinicians via email year round. You should expect a reply within a week. Please submit photos with your email, when possible.

Some Questions You Might be Asked

  • How long has the problem existed?
  • Is it getting noticeably worse?
  • Is more than one plant affected?
  • How often is the plant fertilized?  Fertilizer strength?
  • Have any chemicals been applied near the plant recently?
  • Have the roots been disturbed?  Bark damage?

Plant Problems

Is your plant turning brown or the edges curling? Do your apples have spots? Does your lawn have discolored rings? Master Gardeners can help you identify the likely problem and suggest solutions to restore your plant, lawn or garden to good health.

Plant or insect identification

Did you just move into a house, and there are new-to-you plants in the garden? Did you find an insect that you’ve never seen before? Is there something eating your favorite plant? Bring in a sample or photo, and Master Gardeners will take a look. If your sample is identified as a pest or a weed, they will work with you to develop a management strategy according to recommendations from WSU Extension. If it’s a beneficial insect or plant, Master Gardener volunteers will help you figure out how to keep them around.
