New England Lawn Mowing Guide
New England lawns work within a short season bracketed by snow, and the most important mowing decision happens in fall: take the last cut a little lower so long grass doesn’t mat under winter snow cover and breed snow mold. Cool-season grasses dominate, and fine fescues earn their keep in the region’s shade and rocky, acidic soils.
What grass do you have?
- Kentucky Bluegrass — sunny areas; self-repairing spread.
- Fine fescue — shade, slopes, and low-input lawns; tolerates acidic soil.
- Perennial ryegrass — often blended in for fast establishment.
Mowing heights for New England grasses
| Grass | Mowing height | Notes |
|---|---|---|
| Kentucky Bluegrass | 2.5–3.5 in | Raise to 3.5 in in summer |
| Fine fescue | 2.5–4 in | Tolerates tall, infrequent mowing |
| Perennial ryegrass | 1.5–2.5 in | Quick to establish; blend component |
Last cut of the year: drop to ~2.5 in for the final mow so matted grass doesn’t trap moisture and invite snow mold.
