Mid-Atlantic Lawn Mowing Guide
The Mid-Atlantic is the transition zone at its hardest — too hot in summer for cool-season grass, too cold in winter for warm-season grass. Tall fescue wins here because it’s the most heat- and drought-tolerant cool-season grass, but only if you raise the cut to 3.5–4 inches through summer. Cutting fescue short in a Mid-Atlantic July is the fastest way to a brown August lawn.
What grass do you have?
- Tall fescue — the regional workhorse; deep roots, heat tolerance, stays green with a high cut.
- Kentucky Bluegrass — often blended with fescue for self-repair in sunny areas.
Mowing heights for Mid-Atlantic grasses
| Grass | Mowing height | Notes |
|---|---|---|
| Tall fescue | 3–4 in | Keep at 3.5–4 in June–August — the #1 survival lever |
| Kentucky Bluegrass | 2.5–3.5 in | Raise toward 3.5 in in summer |
Humidity brings brown patch in mid-summer; the high cut plus morning watering keeps it in check.
