What are your worst plant enemies?
I have a severe problem with quackgrass (aka couchgrass, Elymus repens), which I have struggled with for over a decade. I don’t use any chemicals in my garden, so it means a great deal of elbow grease is necessary. While I have made significant inroads, I cannot ever let my guard down!
One plant enemy I am so glad I don’t have in my garden is Canada thistle (Cirsium arvense). Are thistles a problem where you live?
