Master Gardeners identify plant problems and plant pests and recommend solutions to manage them at our diagnosis clinic.
We normally hold in-office clinic and take telephone calls, but due to COVID 19, our offices are closed. Please contact us by:
- email your question to ChelanMasterGardeners@gmail.com
- include your name & city, phone number
- indicate if we may contact you during our clinic hours
- state your question concisely and include as much information as possible.
- include the plant name, age, growing conditions, and symptoms
- some questions are more complex than others and are better addressed in a discussion and with a sample of the plant. We may recommend you call or visit us during clinic hours.
Is your plant turning brown or the edges curling? Does it have black spots or is it turning yellow mid-summer? Does your lawn have discolored rings? We can help you identify the likely problem and suggest solutions to restore your plant, lawn or garden to good health.
We’ll pull resources from our library and consult WSU’s Hortsense, an online resource. If we don’t know the answer, we’ll forward the problem to WSU professors.

What are those tiny white flies hovering over and on your plant? What’s causing pine needles to brown? Why is the edge of leaves scalloped? Why is a leaf getting pale?
When you bring in a sample of a damaged leaf or branch, we can examine it by microscope or hand lens to identify the culprit. Using Washington State University’s online resource Pestsense, we can print information you can take home and learn how to manage your problem.
We’ll also explain which flying insects are your garden’s best friends and which are its foes.
