My Neighbor Sprayed Paraquat In Her Driveway Last Fall And It Apparently Killed All The Grass On My Side. When Can I Replant?

Question

She had previously sprayed Roundup in the driveway, and the weeds kept coming back, so her boyfriend gave her paraquat. The driveway slopes to my side and a quarter of the grass in my yard on that side is dead along with 2 azaleas and a small Japanese Maple tree in a bed in the front. Is there residual weed killer in the soil? I live in centra North Carolina.

Answer 1

Paraquat is said to adhere to soil particles for many years but in an immobile state. It is supposed to only be used by licensed applicators.
