Does this prevent nutsedge from growing (yellow or purple)?
Nutsedge is a summer weed that is hard to control using a pre emergent such as Prodiamine 65 WDG (Generic Barricade). Nutsedge is controlled after emergence in cool and warm season turf grasses such as St. Augustinegrass, Bermudagrass, Kentucky Bluegrass, tall and fine fescue, and perennial ryegrass. Sedgehammer is considered one of the more "gentle to turfgrass" products and the most widely used for controlling both yellow and purple nutsedge.
