Overwintering Geraniums in Paper Bags: The Upside-Down Dormancy Method

Method

1. Cut stems back to ~8 inches.
2. Remove from pots, shake off most soil.
3. Place upside down in paper bags (plastic causes mold).
4. Store in cool (45°F), dark location.

About 80% survive. Pot up in early April, water, and they'll regrow.

Alternative for Prized Varieties

Keep in a sunny window and take cuttings in February for insurance.
