Caladium Care: Colourful Leaves and a Winter Rest
Care for Caladium bicolor through active growth and dormancy.
Quick questions
Does caladium keep its leaves all year?
No. It commonly rests after the growing season and can return from a firm tuber.
How much light does it need?
Use bright filtered light or partial shade; protect thin leaves from harsh sun.
How often should I water it?
Keep the mix moist during active growth, checking the pot and draining it. Reduce water during rest.
Is caladium safe for pets?
No. It contains irritating calcium oxalates. Contact a veterinarian if a pet eats it.
Can I throw away a leafless pot?
First check the tuber. A firm resting tuber may grow again when conditions improve.
Caladium bicolor grows from a tuber and is prized for its colourful, thin leaves. The photograph shows one outdoor leaf; cultivars vary widely in pattern. It is a seasonal plant, so expect a resting period rather than year-round foliage.
Light and growing-season water
Give it bright, filtered light or partial shade. Strong sun can damage delicate leaves. While leaves are actively growing, keep the mix moist but draining: check the pot often, water when the surface begins to dry and let excess escape. Do not use a fixed weekly interval.
When growth stops
As foliage fades in the cooler season, reduce water. A firm tuber can rest until warmth and light prompt new growth. Keep a resting tuber away from cold and wet conditions. Resume careful watering when shoots appear.
Leaves and safety
Wind, handling and pests can mark the thin leaves. Inspect the undersides before treating. Caladium contains irritating calcium oxalate crystals and should be kept from pets and children. If a pet chews it, contact a veterinarian.
