Sprayed Mulch-What to Do


Q: Last summer I sprayed my pasture with GrazonNext, containing aminopyralid and 2,4-D . I have a pile of wood chips that I use as mulch around various plants. When I was cleaning out my sprayer I sprayed my mulch pile. Can I use the mulch on the surface of the ground around plants in the garden?

A: Much depends on how much chemical was sprayed on the mulch and then the subsequent temperatures and rainfall. It would be a gamble to use the mulch around plants now. Better leave it in place for at least another twelve months.
