Overwintering Sugar Maple Seedlings in Cold Climates

Overwintering Sugar Maple Seedlings in Cold Climates

If your father's tree is a hybrid, seedlings won't be true-to-type. Regardless, protect young seedlings in pots through Wisconsin winter:

1. Sprout seeds as before; separate into individual pots when larger.
2. When dormant, move pots to an unheated garage (cold but not brutal).
3. Water periodically (no rain/snow access).
4. Prevent premature warm-up; keep cold until spring.
5. By second fall, they're hardy enough for outdoor pots or planting.
6. Shield from harsh north winds.

Sentimental value makes the effort worthwhile.
