It’s not a surprise that Master Gardeners have gardens! Of course, most of us tend our own back-yard gardens, but we also are proud of several other gardens in Yakima County where we have put in efforts to benefit our community.

Demonstration Garden – Ahtanum Youth Park

Created in 2005, our featured Demonstration Garden is an ongoing project funded entirely through charitable donations.

The garden is always open for you to visit, during park hours, at the Ahtanum Youth Park, 1000 Ahtanum Road in Union Gap. It is located near the Red Youth Barn in the southeast corner of the park.

It is tended entirely by Master Gardener Volunteers.

Heirloom Garden

Master Gardeners have set aside a private area where we are growing heirloom vegetables. We use this garden to experiment with rare and unusual varieties, and different growing practices. Produce raised here, and not used for seed, is donated to area charities. In most years nearly 1,900 pounds of vegetables is harvested for them.

A primary goal of this garden effort is the saving of seeds. We have developed a seed library with seeds from this garden. You can become a member of this seed library by attending training in the early spring each year. Watch for the announcement of date and time on our Events Page.

See more photos and information on the Heirloom Garden page.

Food Garden

In the West Valley of Yakima, we have developed a garden dedicated solely to growing fresh vegetables for area food banks.  Annually, we take nearly 3,000 pounds of vegetables to the Highland Food Bank.

Many folks from the Yakima Valley are familiar with the Master Gardener Annual Plant Sale. The first weekend in May of each year we host this huge sale of tens of thousands of plants… annuals, perennials, vegetables, herbs, hanging baskets, garden art and more. It all happens in our greenhouse, where we raise all these plants.

Starting in October, we take cuttings, start seeds, plant plugs, nurture, pot and re-pot, so that by May we have this glorious abundance to share with you. This sale is our primary funding tool to support the work we do throughout the year.

We are working now in the greenhouse to provide beautiful plants starts and other garden treats for you!
