Without chemicals, you will not stop it. If you are doing a small spot, you may control it but it will not be stopped until you kill all roots.4grandbabies said:I am battling it also. amd I think it is Johnson grass..I pull it by the roots in small areas if I see it before it gets too big.
It is a battle, and I agree, dont know if it can be done without chemicals, but I am not using chemicals. I run a long knife blade down in under it and try to cut off what I cant pull.
Hate the stuff!!
