Killing Crab Apple Weeds

Question

I recently cut down an old crab apple tree, but the pesky red weeds are still growing from the roots. I did have the stump grinded, but the red weeds are still growing. Is there a specific poison or other chemical I can apply that will not kill my grass?

Answer 1

You can try a selective herbicide and see if it will take care of them. Those will not kill grass.

If that doesn't work you may need to go with a non-selective herbicide such as a brush killer and hold cardboard next to each one while you spray. You can also "paint" the herbicide onto the weeds.
