Rosalie Preble, a member and past president of the Juan de Fuca Chapter of the American Rhododendron Society, talks about propagating rhododendrons from cuttings at the next Green Thumbs Garden Tips education series session.

Preble offers “Propagating Rhododendrons from Cuttings” from noon-1 p.m. on Thursday, Sept. 10. To join, access the link from WSU Extension’s website at extension.wsu.edu/clallam/events.

An alumna of the WSU Clallam County Master Gardener program class of 1997, Preble will provide information on taking and preparing rhododendron cuttings, providing optimal environmental conditions that encourage rooting, and caring for the new plants.

Her talk, program organizers say, will add to gardeners’ understanding of the variables involved in successful rhododendron and other woody trees and shrubs propagation.

Preble has more than 20 years of experience in propagating numerous species of shrubs and trees, including rhododendrons and azaleas. She said she enjoys sharing cuttings with family and friends and WSU Clallam County Master Gardeners for the organization’s plant sales fundraising events.

She was awarded the Golden Trowel for lifetime achievement for her contributions to the WSU Master Gardener program.

Sponsored by WSU Clallam County Master Gardeners, the Green Thumbs Garden Tips education series looks to educate home gardeners on topics relevant to planting and maintaining sustainable gardens and landscapes in Clallam County.

Live streaming presentations are available on the second and fourth Thursday each month through October (in November, December and January, one program is offered).
