Christine Heycke will talk about colorful structures called plant galls during her “All About Galls” Zoom presentation, set for noon-1 p.m. on Thursday, June 24.

Heycke will explain what plant galls are and provide lots of images of galls that may be seen on walks, hikes and even in one’s own garden and backyard. She will discuss life inside the gall, how galls are both beneficial and detrimental to humans, the need for gardeners to be aware of galls’ potential effects on ornamental and edible plants, and if action is needed, which remedial efforts are most likely to be effective.

Heycke became interested in galls after watching a webinar on plant galls years ago. She began reading books and research articles on galls, joining the British Plant Gall Society to get more information on various types of galls and correspond with people who study them. An urban planner, Heycke is a master gardener with the Jefferson County

Extension who enjoys traveling and learning foreign languages.

Sponsored by WSU Clallam County Master Gardeners, the Green Thumbs Garden Tips education series seeks to provide home gardeners with education on research-based sustainable garden practices in Clallam County.
