Fertilizer Overdose on Lawn: Recovery Steps for Bermuda and Zoysia

The Damage

Standard rate for 34-0-0 is 3 lbs/1,000 sq ft. You applied 8× that (three 40-lb bags on 5,000 sq ft). Grass wilts and browns from nitrogen toxicity.

Recovery Plan

1. Irrigate every few days to leach excess nitrogen.
2. Urea decomposes rapidly in hot, moist conditions.
3. Test readiness weekly: sprinkle fescue seed in 3-ft squares. When it germinates and survives 2 weeks, try sod patches.
4. Full re-sodding likely not until mid-August or later.

Faster (Costly) Option

Scrape off top 3 inches of soil, replace with screened topsoil, sod next week. (Sell removed soil as fertilizer to neighbors!)
