Join the Washington Native Plant Society for this awesome webinar!

Mature native trees are a highly valued asset in both built and natural area landscapes.  Adding new plants and maintaining existing plants within the shade and root zone of large trees can present challenges for the trees and companion plantings alike. Misunderstandings about mature trees and their roots often leads to stress or death of trees intended for preservation.  This talk will cover practical and sustainable methods for improving the long-term success for the trees and surrounding landscape.

You are invited to a Zoom webinar.
When: Apr 12, 2023 07:00 PM Pacific Time (US and Canada)
Topic: NPAM: Gardening Under Native Trees
