Washington County Master Gardener Association invites you to the third of three classes on mason bees led by Ron Spendal. Attendance at the previous Mason Bee classes is not necessary to attend this class.

In this hands-on workshop, you will learn how to extract, clean, and store mason bees. If you have cocoons ready for cleaning, bring them along. If you don’t have cocoons, we have plenty for you to practice with.

Ron Spendal is an OSU Master Gardener who has been researching and educating on mason bees for over 15 years. He operates educational mason bee displays across Washington County, Oregon and runs a highly sought-after course on mason bee management through the Washington County Master Gardener Association. Ron designs and builds his own equipment. He conducts research in conjunction with Oregon State University and Montana State University. His work with mason bees has been featured on the Oregon Field Guide program on OPB. He has invented a cocoon cleaning device that uses dry sand and can clean up to 100 cocoons in 3 minutes.
