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. Maine 1.5–2.5 in, at the high end for most lawns; New Hampshire 3 in or more; Vermont 3–4 in in spring and summer; Rhode Island 2–3 in, and at least 3 in on the same URI page |
| Fine fescue | 2.5–3.5 in | Tolerates tall, infrequent mowing. Maine 2–2.5 in for red fescue, 2.5–3.5 in in shade; New Hampshire 3 in or more; Vermont 3–4 in in spring and summer; Rhode Island 2–3 in, and at least 3 in on the same URI page |
| Perennial ryegrass | 2.5–3.5 in | Quick to establish; blend component. Maine 3 in or more (its table gives 1.5–2 in); New Hampshire 3 in or more; Vermont 3–4 in in spring and summer; Rhode Island 2–3 in, and at least 3 in on the same URI page |
The height column is UMass Extension’s range for Massachusetts; the notes give the other states’ extension figures.
Last cut of the year: keep mowing until the grass stops growing; UMass says that reduces snow mold damage. UVM (Vermont) lowers the deck gradually so the final mow is about 2–2.5 in. Shorter grass is less likely to mat under snow, trap moisture and invite snow mold.
New England mowing calendar
| Month | Mowing & lawn care |
|---|---|
| Jan | Dormant under snow. No mowing. |
| Feb | Dormant. Sharpen the blade; plan spring. |
| Mar | Still cold; growth not yet started. |
| Apr | Green-up and the aggressive spring flush begins; first mows. |
| May | Peak spring growth: mow weekly or more. |
| Jun | Strong growth; begin raising the deck for summer. |
| Jul | Heat lull: mow at the top of your grass’s range (3–3.5 in in Massachusetts), less often. |
| Aug | Continued heat; hold the high cut. The best seeding window opens August 15 in Maine and about the third week of August in Massachusetts. |
| Sep | Best month: overseed (by September 15 in Maine, about the third week in Massachusetts), fertilize, mow weekly. |
| Oct | Strong fall growth; keep mowing until the grass stops growing. |
| Nov | If it is still growing, take the last cut at about 2–2.5 in (Vermont); mowing until growth stops reduces snow mold damage. Then done. |
| Dec | Dormant. Rest. |
