Woodsman, spare that tree.or maybe not

WSU Extension Bugs and Blights series

Learn to recognize conifer decline in the landscape, determine the cause, and take proper action.

 

EVERETT, Wash. –Threats to our backyard and neighborhood forests can come from insects, diseases, the environment, and more. Often, it’s only after the tree comes down that homeowners learn the roots were full of rot, destined to topple in the next good breeze. Unfortunately, the symptoms may be subtle and mimic other less serious problems, or be missed altogether. The last Bugs & Blights session for 2008 will focus on the multiple causes of conifer decline, a common problem throughout the Pacific Northwest.

 

In this two-hour workshop you’ll learn to recognize the symptoms of a broad variety of conifer health issues along with a host of corrective measures and next steps. The class is offered three times on Wed. Nov. 19th at 10 a.m., 1 p.m., and 6:30 p.m. Location is WSU Snohomish County Extension, Cougar Auditorium, 600 – 128th St SE, Everett, WA 98208.

 

Topics covered will include the distinction between foliage diseases and general decline with samples and diagnostic tools. Both needle- and scale-type trees will be covered. The forest surrounding Extension’s McCollum Park offices provide living and dying examples in the hands-on lab portion of the class.

 

Cost is $20 per person or $10 for active Master Gardeners.
