2020 Events

Plant Sale

The Master Gardeners of Yakima County have had a wonderful tradition of our Spring Plant Sale for over 25 years.  And this year will be no exception.  However, because of the obvious and important limitations of the Covid-19 pandemic, things will be different this year.

Shop Green Gardens and Roots Nursery!

You can find many of our annuals, hanging baskets, and tender succulents for sale at Green Gardens, at 102 Jim Clements Way, in Selah.  And Roots Nursery, at 6910 Tieton Dr., in Yakima, has many of our annuals and perennials for sale!

These merchants have been good enough to make these Master Gardener-raised beautiful plants available for you to purchase. Please thank them!
