Demonstration Gardens

The Master Gardeners of King County maintain ten demonstration gardens, three youth gardens and one outreach garden. In each of these gardens, the community can see firsthand the types of plants that grow well in our area, and learn recommended planting practices and overall garden care. Visitors can also enjoy each garden’s unique beauty and large variety of plants. Old favorites grow alongside new experimental varieties.

Volunteers maintain the gardens throughout the year using techniques learned in the Master Gardening Training Course and Continuing Education programs.   If you see a “work party” in progress, stop by and talk to our volunteers. They’ll be pleased to show you the gardens and answer your questions.

In addition to MGFKC demonstration gardens, we have included a list of public gardens in King County and the surrounding area.  We encourage you to visit these gardens to inspire, inform, and excite you about the beauty of plants for your gardens and their many medicinal, cultural and edible characteristics.

Vashon Dry Garden

In 2015, Master Gardeners studied what types of tomato plants do best in a dry garden. They harvested “a ton of tomatoes” and watered only once a month. In 2016 the Master Gardeners will study what varieties of beans do best in a dry garden. Each year, Master Gardeners will select one or two types of plants to focus on.The garden is completely organic and is very low maintenance. Dry gardening conserves every bit of moisture in the soil for plants to use.

The garden is located at the Vashon Community Care Center, 15333 Vashon Highway SW, on Vashon Island. Since only a few weeds need to be pulled each week, making the garden very low-maintenance, there are no regular work parties. Read more about this garden in the August 2016 issue of The Connection.
