Have a Gardening Question? As a trained OSU Master Gardener volunteer!

OSU Master Gardener program staff and up to three trained Master Gardener volunteers will be onsite at the Clatsop County Extension Office for all of your gardening questions. You can visit the office, call, or email for assistance identifying your weed, disease, and insect problems, as well as research-based management suggestions for these issues. Feel free to bring in plant or insect samples to assist with identification and diagnosis, or soil samples for free pH testing.

For in-person assistance, visit the Clatsop County Extension Office at 2001 Marine Dr. Room 210, Astoria, OR 97103. Plant, insect, and soil specimens dropped off during other business hours will be handled by Master Gardener Volunteers during Plant Clinic hours. All soil pH testing will be conducted on Thursdays.

Call the office at 503-325-8573 during Plant Clinic hours to speak with a Master Gardener volunteer. If calling outside Plant Clinic hours, please leave a voicemail and a Master Gardener volunteer will contact you back during Plant Clinic hours.

Questions can be sent through email to clatsopmg@oregonstate.edu at any time and a Master Gardener volunteer will respond to you during Plant Clinic hours.

You can also find Master Gardeners in person answering plant questions every Wednesday at the Seaside Farmers Market from 1-6 pm and every other Sunday at the Astoria Sunday Market from 10 am to 3 pm.
