Turf Builder Weed & Feed with WeedGrip technology. Grips the weeds you see and the ones you don't. Kills dandelions, clover, and other major listed lawn weeds. Builds thick, green turf from the roots up without burning your lawn. Feeds grass to crowd out future weeds. Keep people and pets off lawn during application. It is best to limit activity on the lawn for 24 hours after application, but people and pets can enter the treated area after the dust has settled on the lawn.
