Washington County Master Gardener


The Washington County Master Gardener Association (WCMGA) plant sale, Gardenfest, that was to be held on April 25, 2020, as well as other WCMGA events, have been cancelled out of concern for the community and in compliance with government and OSU mandates. WCMGA is examining options to sell the existing large inventory of plants in our greenhouse and may be able to offer those for sale in some manner after mid-April.

Check back on this website for updates on all our events going forward.

WCMGA is a non-profit. As Gardenfest was our major fundraiser for the year, we are looking for other options to raise the funds needed to operate our education and learning gardens and conduct our normal garden-education focused operations. We welcome your donations! You can click the yellow donate button at the bottom of our home page to donate. Other ways to donate include: shopping at Renee’s Seeds and entering order code FR2019A2, shopping at Fred Meyer and linking your rewards card to WCMGA, or shopping on Amazon Smile and choosing WCMGA as your charity.
