If weeds are already a problem, we recommend spraying with Speedzone®. Speedzone® is a broad spectrum herbicide that controls most broadleaves.
If crabgrass is the issue, apply a crabgrass preventer when soil temps reach 55 degrees, approximately early May.
If you have other undesirable species, such as Brome and/or Quackgrass, then please accept our condolences. You don’t have a lot of options other than spraying out with glyphosate and starting over.
2 weeks for Speedzone®
2 weeks for glyphosate (Roundup®) in most cases
Apply a crabgrass preventer in the spring, followed by a turf builder in early June, and then winterize in late August or early September.
