Do you know of a source in the greater Seattle area or North Puget Sound that will take and recycle 1 gallon black plastic pots that nursery stock comes in?
If you have recycling service in the city of Seattle, you may put clean plastic plant pots in your recycling bin. If you do not have access to recycling, here are some other options. Search “plastic nursery pots” on King County’s What Do I Do With… website. Several nurseries are listed, including West Seattle Nursery, Clinton Bamboo Growers, Molbak’s, and Flower World.
You can also contact the Washington Park Arboretum’s Pat Calvert Greenhouse to see if they are accepting nursery pots. Call 206-325-4510 or email info@arboretumfoundation.org.
