Seattle Tilth maintains two demonstration gardens, one at the Good Shepherd Center in Wallingford and the other at Bradner Gardens Park in Mt. Baker.  These gardens are wonderful teaching tools for the public who may tour the gardens at any time, free of charge, as well as Seattle Tilth volunteers who work alongside staff to install and maintain the plantings. 

Our original garden at the Good Shepherd Center was built in 1978 by a group of Tilth visionairies who knew our city needed an urban agricultural center.  With the support of the Wallingford Chamber of Commerce and the Good Shepherd Center, these volunteers ripped up old concrete play courts and created a garden that has educated and inspired for nearly thirty years. Our demonstrations include year round vegetable gardening, drought tolerant and disease resistant ornamental plantings, yard waste and food waste composting, and soil building techniques.

Our newest garden at Bradner Gardens Park was built in 2000.  Bradner Gardens Park is a unique collaborative partnership between City of Seattle Parks Department, Seattle Tilth, Washington Native Plant Society, King County Master Gardeners, Department of Neighborhoods P-Patch Program and neighborhood residents.  The park's demonstrations are entirely maintained by volunteers and are 100% organic.  The Seattle Tilth gardens showcase raised beds, attracting beneficial insects, swale gardening, soil building, drip irrigation and year round vegetable gardening.   

We encourage you to stop by and take a self-guided tour or get involved by taking a class or volunteering with our Garden Crew.
