**Mulch and Mycorrhizae

You’ve probably seen them before – those white threads too long and slender to be roots, yet intimately associated with the root system of trees and shrubs. The threads are fungal hyphae, and their association with many plant species are collectively called mycorrhizae.

These fungal partners are also dependent on woody mulch, especially those mulches made from natural woody debris. Understanding how roots, mycorrhizae, and decomposing wood all are interconnected helps us make good management decisions regarding mulch use. Most importantly, this information helps gardeners avoid using fungicides, which kill these beneficial species.  Join our March Speaker Series, as Dr. Linda Chalker-Scott, Washington State University Urban Horticulturalist presents.
