| If you are just trying to make sure they are dead you could always lay boards or tarps, even garbage bags held down with rocks over the top of the affected areas. Without sunlight, the roots will not spawn off new branches that can last too long.
This will stop them from growing but won't do much to help you get rid of the stumps/intact roots.
Can a stump grinder be used in such a situation, or would all that dirt and little stump play havoc with the machine and its blades and not be worth it?
I agree that chemicals will just spread downhill and hurt your other grass or water supplies. And may not be enough with one application. |
