Overwintering Candy Corn Plant (Manettia) in Iowa

Manettia (candy corn vine) won't survive Iowa winters outdoors. Bring it in before temperatures drop below 55°F.

Indoor Requirements

• Light: Bright south/west window
• Humidity: High—use pebble tray or humidifier
• Temperature: Warm (65–75°F)
• Water: Evenly moist; water when surface dry
• Pot: Keep rootbound to promote flowers
• Pruning: Maintain shape; root cuttings in peat/perlite under plastic

Transition Challenge

After summer outdoors, acclimation to lower indoor light is difficult. Maximize light exposure. Expect some leaf drop. Fertilize half-strength during active growth.
