Ask a Master Gardener

Have a Gardening Question? Ask 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.

Plant Clinic hours are every Tuesday from 9 AM to 12 PM and every Thursday from 1 PM to 4 PM from May 14th to October 17th, 2024, excluding July 4th. There will be no Plant Clinic on July 4th (holiday), July 30th (county fair), and August 1st (county fair).

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 [email protected] at any time and a Master Gardener volunteer will respond to you during Plant Clinic hours.
