Final Fall Mowing Height for Long Island Lawns

Fall Growth Pattern

Cool-season grasses (bluegrass, rye, fescue) surge in fall—cool nights, warm soil, moisture. Mowing continues regularly.

Final Cuts

As growth slows (late Oct–Nov), lower mower deck ½–1 inch for the last 2 mowings. Benefits:

• Reduces long leaf tissue that mats under snow.
• Encourages root density (shorter tops = more energy to roots).
• Not primarily for fungus prevention—root effect is more significant.

Don't Scalp

Never remove more than ⅓ blade height at once. Gradual reduction over 2 cuts is safe.
