Results will begin to show days after applying this Scotts weed control. Lawn feeding helps build thicker, greener turf with deep strong roots. Use on bahia, bermuda, bluegrass, centipede, fescue, ryegrass, or zoysia lawns. Apply granules with a Scotts broadcast, rotary, or drop spreader (one 43.89 -lb. bag covers 15,000 sq. ft.) when weeds are actively growing and the grass is moist.
