Master Gardeners Available

Master Gardener Email:

Trained WSU Master Gardeners will take your plant problem questions via e-mail at snocomg@gmail.com.  Please provide as much information as possible about the plant and it’s growing conditions. Photos are very helpful.

Master Gardener Hotline: 425-357-6010

Trained WSU Master Gardener Volunteers will be on duty to answer your plant problem questions from 10 a.m. to 3 p.m., weekdays, Apr. 1 thru Sept. 30. Please understand that this is a new process for us during the Covid-19 Emergency and that there are probably going to be some glitches so please have patience. Master Gardeners will be working from their homes with more limited resources but will do their best to research and answer your questions. They will also be working with only one incoming phone line, so you may need to call them back. If they call you back, their call will probably register as “restricted” on your phone. To talk to a WSU-Snohomish County Extension Master Gardener, please call 425-357-6010 from 10 a.m. to 3 p.m. weekdays, Apr. 1 thru Sept. 30.
