Caladium (angel wings) care

Light

Caladium is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Bright indirect light. Some cultivars (sun-tolerant types) take morning direct sun. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water caladium when the top 1-2 cm of soil is dry, every 4-7 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Likes consistent moisture during active growth; allow to dry once foliage yellows for dormancy.

Soil and pot

Caladium grows best in rich free-draining mix. Compost with 20% perlite; tubers planted 5 cm deep. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Caladium sits happiest at around 60-70% humidity and 21-29°C (70-85°F). High humidity prevents leaf-edge browning. If you keep the room above 21 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed caladium sparingly. Half-strength balanced feed every 4 weeks during active growth. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on caladium in the Growli community. Each is annotated with the most common cause so you know where to start.

• Yellow leaves and dieback in autumn — Normal — going into dormancy. Lift and store tubers at 18°C.
• Browning edges — Low humidity or dry soil.
• Pale washed-out colour — Too much direct sun.
• No regrowth in spring — Cold storage or rotted tuber; store at 18-21°C, never below 13°C.

Propagation

Divide tubers in spring before potting; each section needs at least one eye. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Caladium is toxic to pets. ASPCA lists Caladium as toxic to cats, dogs, and horses due to insoluble calcium oxalates. Causes oral irritation, vomiting, and difficulty swallowing. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
