When I moved into my house last summer, there was a small corner of
mint. This spring, my entire backyard is covered with the stuff!
There's way too much to dig out by hand.
Looking at old posts, it looks like Roundup might be the best bet. But
I have 2 big old oak trees back there, and their roots are through the
backyard as well. Will the Roundup kill the trees? If so, what else
can I do?
Roundup is going to kill everything growing on the ground in your yard,
including the grass (but probably won't hurt the trees). Try one of
those specialized broadleaf weed killers instead. It will work on the
mint, dandelions, etc but save what lawn you might have.
