Walla Walla Downtown Farmers Market

The WSU Walla Walla County Master Gardeners are once again bringing hands‑on, research‑based gardening support to the Walla Walla Downtown Farmers Market this spring and summer. Visit the Master Gardener booth on the 2nd and 4th Saturdays of May through September, between 9:00 a.m. and 1:00 p.m., for timely gardening tips, seasonal demonstrations, and answers to your yard and garden questions.

Each month features a unique theme designed to help local gardeners build skills and confidence throughout the growing season:

May – “Midsummer Night’s Scheme”
Garden planning fundamentals including seed starting, garden design, site analysis, and general preparation.

June – “Pride & Plantability”
Planting trees, shrubs, vegetables, and natives — with a focus on choosing the right plant for the right place.

July – “Fahrenheit 105”
Heat‑smart gardening: protecting plants during extreme heat and other adverse weather conditions.

August – “A Preservable Feast”
Harvesting, storing, and preserving fruits and vegetables to extend your garden’s bounty.

September – “Rake Expectations”
Fall stewardship, pruning, mulching, and preparing the garden for winter.

The Master Gardener booth offers visitors a friendly place to ask questions, explore sustainable gardening practices, and connect with volunteers dedicated to community education and environmental stewardship.
