Reviving Lawn Burned by Weed Killer

Over-application of weed killer can brown grass, but recovery is possible if roots or crowns remain green. Mow slightly shorter to remove damaged blades, then apply a liquid fertilizer like Peters to stimulate regrowth. Milorganite (6-2-0) is excellent for overall lawn health, but Peters is better for damaged roots. Water deeply but infrequently—use a tuna can to measure 1 inch per session, then wait until it evaporates before watering again. Daily soaking promotes fungus and root rot. If no green tissue remains at the base, reseeding or resodding will be necessary. Scotts Weed & Feed is a reliable product for future weed control; follow label precautions for your grass type.
