Cool Plants/Hot Tips

Sep 12 2021 Cool Plants Hot Tips Plant Sale
Thank you to all who participated in the September 12 Fall Plant Sale. Despite the Seattle mist start, the throngs of excited gardeners descended on Bellevue Botanical Garden early on Sunday. Ciscoe Morris, Nita-Jo Rountree and Christina Pfeiffer joined the talented guides from the Bellevue Botanical Garden Partners to generously donate their time to help the Master Gardener Foundation of King County in this annual fall fundraiser.

We hope you had a chance to buy some fall plants from our local specialty garden vendors and take in a guided talk or enjoy the speakers. You can find the list of the plant vendors on our web page, and we appreciate your continuing support of these businesses through your patronage during the year.

The 500 plus King County Master Gardeners require a strong support system, and the Foundation finances their demonstration gardens, plant clinics and classes. You can find answers to your gardening questions year-round via email at Ask a MasterGardener.

Thank you again for supporting the Master Gardener Program with your generous donations and participation in our events. You may still donate on the Foundation website at year-round. We look forward to seeing you next year.
