Will it kill docks as well?
No afraid not. As said it slows them down a bit but not for long.Will it kill docks as well?
The point is to break the 'cycle'. It astonishes me how many people complain about docks, yet they cut and feed them to their stock and then spread slurry containing the still-viable seeds on land already covered with established docks... .You won't kill them as you have millions of seeds in the soil
