Discovery Gardens Open House – June

Discover the Demonstration Gardens! Explore eight acres of gardens at one location in Skagit Valley on the last Saturday in June!


Skagit Valley is home to three demonstration gardens operated by volunteers as a learning resource for the public.  On the last Saturday of June, the gardens host an open house where visitors are welcome to spend a day with the volunteers who maintain the gardens to learn more about the gardens and gardening.  See plants chosen to perform well in the Pacific Northwest.  Learn about effective garden practices, soil health, composting, pollinators, fruit tree pruning, native plants, weed identification, and more.   Bring your family and friends.
