How Long To Wait After Using Roundup Before Sowing Seed

Question From: Charter Township of Clinton, Michigan, United States
Q: I'm trying to destroy a wide bladed grass that's invaded my lawn. If I use roundup to kill it; how long before I can remove the debris and sow new seed? Thank you

A: If you used it according to the package strength follow the directions on the package. Roundup comes in several strengths and the times vary from 10 days to a year. Best And Happy Yardening, Nancy
