Learn to fight back against weeds

Blackberries, ivy, holly, Scotch broom, reed canary grass, and knotweed are just a few of the invasive weeds that plague landowners. The Washington State University Extension Forestry program is offering a 7-hour invasive forest weed control field practicum to equip landowners with everything they need to know to get a leg up on these invaders. The field practicum will be held Saturday, September 30 from 9:00 a.m. to 4:00 p.m. at the New Tree Farm 1130 Stanwood Bryant Rd Arlington, WA 98223 approximately 1.5 miles from I-5, Exit 212.  Plan to arrive early as doors open at 8:00am to meet invasive weed control organizations and herbicide suppliers.

This hands-on event will include demonstrations and practicing of multiple control techniques such as using a weed wrench, sheet mulching, foliar herbicides, cut stump treatments, and stem injection.  Participants will also learn how to use herbicides safely including what products to use and where to buy, how to read and follow labels, practice tank mixing with dyes, and learn pesticide laws. 

The cost to attend is $20 per person or $30 per couple before September 16 and $35/$45 before 5:00 p.m. on September 28.  There is a special student and Master Gardener rate (call for details).
