Please identify the weed in the picture i have attached, I’m near Collingwood a 5B ZONE. Weed is spreading like crazy. The soil is moist, near a brook, now coming up into my gardens. It wasn’t there last year or the tear before.
Your garden has been infiltrated by garlic mustard (Alliaria petiolata) , one of the most rapidly spreading weeds in Ontario.
Please refer to the answer we provided to an earlier inquirer about this invasive plant, here.
