Winter Lawn Care: Skip the “Winterizer,” Mow Lower, Compost Leaves

“Winterizing” fertilizer is a marketing gimmick. Cool-season lawns in the Northeast need:

• Final mow shorter than usual (2–2.5 inches) to reduce snow mold risk.
• No fertilizer after mid-October. Cold soil can’t use it; it leaches or feeds winter weeds.
• Rake leaves into a compost pile—don’t bag them. Leaf compost is gold for next year’s beds.
• Leave a light leaf layer if you mow-mulch them; it feeds microbes.

Chemical programs create fungus-prone, microbe-poor soil. Organic lawns handle winter naturally.
