Overwintering Container Dahlias Indoors in Michigan

After bloom, let dahlias dry back. Cut stems to 6 inches. Store pots in a cool basement (45–50°F), barely moist—just enough to prevent tuber shriveling. No light needed. In spring, refresh soil, gradually increase light and water. Move outside after frost danger passes.
