I sprayed Killzall in my ditch. If I put culverts in with dirt over them, will grass grow over the new dirt?
Killzall Weed and Grass Killer will only kill the vegetation that is directly contacted with the spray. Killzall Weed and Grass Killer does not stay in the soil, and it does not have any residual properties. It will not effect future vegetation.
