This webinar is part of the 2018 series of Advanced Training Webinars for Master Gardeners sponsored by Oregon State University Extension.
Join Melodie Putnam (Chief Diagnostician at the Oregon State University Plant Clinic) for a visual tour of common plant galls found in the PNW. Learn how these unusual plant growths are formed, who the common culprits are (fungi, bacteria, insects or mites?) and if the gall is of concern or just an interesting oddity.
