Overwintering Maple Seedlings in Pots: A Southern Ohio Guide

Don’t Bring Them Indoors

House conditions (low humidity, warm temperatures) will desiccate the seedlings. They need a cold dormancy period.

Garage or unheated shed: Temperatures stay above freezing but provide necessary chill.
Water sparingly: Check monthly; keep soil barely moist, not wet.
Protect from rodents: Use hardware cloth if mice are a problem.

After last frost, move pots outdoors to a shaded spot for a week to acclimate.
Transplant to individual larger pots when 12–18 inches tall.
Plant in ground in fall after leaf drop: dig hole twice the pot width, same depth. Backfill with native soil amended with compost. Mulch 3 inches, keeping away from trunk.

Maples need a winter rest. A garage provides the perfect balance of protection and dormancy.
