Weeds to Watch Out For

Late spring is a good time to put some work into to stopping the spread of invasive weeds on your land. Some particularly nasty ones are garlic mustard, scotch broom, Himalayan blackberry, English hawthorn, tansy ragwort, poison hemlock, thistles, ivy and holly. They all spread rampantly, some are flammable, some are toxic to animals, some are very thorny, and they all crowd out native plants. The goal this spring is to eliminate those in flower before they set seed, especially garlic mustard and scotch broom.
 
A great resource for science-based information on integrated pest management of problem weeds is the OSU Master Gardener service. Contact a Metro Area Master Gardener via an online form, email or phone. You can also find species-specific info in the Resource Directory: https://www.srnpdx.org/land-stewardship.html.
 
Your family and your neighbors will thank you for spending some time controlling invasive weeds on your land.
