Ugh. I've got this on all the perimeters, it's a real nuisance. I think it's a biennial, so corn gluten appied each spring may take care of it - it's going to be a never-ending battle, though, because it's in all the wild areas of my town.

It will be impossible to really eradicate it without a town-wide effort.

I hate this stuff. I live next to a wild catch basin/power coridor where it flourishes along with Rosa multiflora and a variety of other thugs. Every spring I yank out hundreds of seedlings from my perimeter garden but no way can I eradicate the field areas. I did read somewhere that if you go out in early spring and weed whack the rosettes to the ground you can prevent it from flowering. If you have lots it might be worth a try.

The Brooklyn Botanic Garden has a recipe for Garlic Mustard Pesto...

Here is a link that might be useful: Garlic Mustard Pesto

This plant is all over our town. Lately some has cropped up in my garden, which I pull right away. Gee, if the pesto tastes that good, people may cultivate the weed. I've used early dandelion greens in salads.

It is rampant, but I yanked up most of it. The good thing is that my chickens and bunny love it, and have eaten every morsel of garlic mustard I've given them. If it comes back, I'll turn the flock out to eradicate it. Of course, they'll also eat my perennials... lol
