Recovering from a Massive Nitrogen Overdose on Your Lawn

Four bags of 34-0-0 on 3,200 sq ft is a severe overdose. The safe rate: 100 ÷ N% = lbs per 1,000 sq ft (here, ~3 lbs). Bermuda may survive; fescue, zoysia, St. Augustine, and centipede likely won't. Excess nitrogen will leach with rain—hopefully not into waterways. Rake out dead blades and wait. Survival is uncertain.
