Weed-and-Feed Burn in Summer Heat: Recovery Steps

Applying weed-and-feed in 90°F heat burned a lawn. Recovery: water deeply (1–2 hrs) daily for several days to flush salts, then deep twice-weekly through summer.

Rules: Never fertilize cool-season grass in summer. Never apply broadleaf herbicides (weed-and-feed) above 85°F. Use spot-spray herbicide in spring/fall instead. Water deeply once weekly (1 hr), not 20 min 3x/week. Transition to organic to avoid burn.
