Managing Dormancy in Deciduous Indoor Plants

By Taryn Moore · October 7, 2026

Understanding Plant Dormancy

Dormancy is a natural survival mechanism where plants slow or stop growth to conserve energy. Many indoor plants require a dormancy period for long-term health.

Which Indoor Plants Go Dormant?

Amaryllis: Loses leaves after blooming; needs 8–10 weeks of rest
Caladium: Leaves die back completely; tubers rest 3–5 months
Oxalis (shamrock): Collapses dramatically, rebounds from rhizomes
Cyclamen: Summer dormancy; cool, dry rest after spring bloom
Begonia (tuberous): Top growth dies back; tubers stored dry

Care During Dormancy

Water Reduction

Cut watering by 50–75%. For tuber-forming plants, stop watering entirely once foliage dies back and store in barely moist peat moss at 55–65°F.

Light and Temperature

Move to a cool, dim location. Reduced light signals the plant to maintain dormancy.

Do Not Fertilize

Dormant plants cannot process fertilizer. Wait until first signs of new growth before resuming feeding.

Breaking Dormancy in Spring

Gradually increase light, temperature, and watering over 2 weeks in late February to March. Apply diluted fertilizer at first sign of new shoots.
