Reviving a Heat‑Stressed Lawn in Cincinnati

Assessing Summer Damage

After a hot August, brown patches may be dormant, not dead. Wait until spring to see if they recover. Cool‑season grasses (common in Ohio) often go dormant in heat and green up with cooler fall temperatures.

Fall Renovation Plan

• Aerate and overseed now: Early fall is ideal for cool‑season grasses.
• Don’t rake out brown areas yet: They may fill in from surrounding grass or new seed.
• Water deeply: 1 hour once a week, not daily light watering.
• Mow high: 2.5–3.5 inches; never remove more than ⅓ of blade height.

Fertilization Schedule

Fertilize in late spring, early fall, and late fall. Avoid fertilizing June–August. Use plain lawn fertilizer without weed‑control combos. Apply to dry grass, then water in.

Key Takeaway

Patience and proper cultural practices—deep watering, high mowing, timely fertilizing—will restore the lawn better than aggressive raking or extra chemicals.
