Kill Bentgrass Before Overseeding

Question From: l. denofio - RHODE ISLAND
Q: I plan on putting down tenacity the 1st week of September to kill bentgrass before I overseed.Then in 2 weeks cut very short and rake and aerate before seeding. Will the tenacity hurt the new seeding and should I also use a starter fertilizer and still put some peatmoss and loam mixture to lightly cover bare spots?

A:

I am not familiar with tenacity Larry. Check out the label, it should tell you when it is safe to re-seed. Do your home work to be sure this product will do what you want it to do. I am not aware of any herbicide that will kill bent grass and leave other varieties alive. Best and Happy Yardening, Nancy
