Mimosa Weed -- how to kill it ?
At least I am told this is the name of the weed. It looks like a baby mimosa tree and has little pea like seeds on the underside of the weed. I need help getting this weed under control.
Some areas have grown up to over a foot tall and I was able to cut those with shears and bag them. But the problem is in an area where the lawn has not been kept up (to the side of a garage where only the dog seems to venture), and this stuff is like a carpet on the ground. The mower will not hit it, and it would be next impossible to cut all of it out.
Is there a good organic type weed killer that will kill it, and how can I prevent it from coming back once it is gone ? ? I would also like to allow for the St. Augustine (what little is still there) to live through this assualt on the weed.
