Whether you want to know what’s chewing your rhododendrons, what’s up with your plum tree, why your lettuce is wilting, or how to identify a weed, native plant or insect, the WSU Master Gardener Diagnostic Plant Clinic can help!
The plant clinic is one of the many projects supported by the Master Gardener Foundation of Whatcom County and is run by dedicated, trained volunteers who serve home gardeners and residents with environmentally sound, researched-based advice and solutions to common plant problems.
To learn more and to submit a sample, please visit the WSU Master Gardener Plant Clinic page on WSU’s website.


The successful sleuthing of the diagnostic plant clinic is the cornerstone of the Master Gardener program and how the concept of Master Gardeners got started in the first place. The first program in the nation was founded in 1973 by Washington State University Cooperative Extension. The Whatcom County Master Gardener Program began soon thereafter. Today, Master Gardener programs have taken hold around the US and in Canada, training people in the science and art of gardening and through the clinic sharing horticulture knowledge with gardeners in their community.
Please note that until further notice our Bellingham in-person clinic is closed to the public due to COVID restrictions. If you have questions, please feel free to call the office or email the program at .
