Caladium 'Carolyn Whorton' (Carolyn Whorton caladium) care

Light

Bright but filtered. Caladium 'Carolyn Whorton' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright indirect light or dappled shade brings out the strongest pink. Fancy-leaf types tolerate more shade than strap-leaf caladiums; harsh midday sun scorches and bleaches the pink markings. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering caladium 'carolyn whorton': when the top 2-3 cm of soil is dry, often every 4-6 days in active growth. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep evenly moist while in leaf — never waterlogged, never bone dry. Taper water sharply as leaves yellow in autumn, then keep the dormant tuber nearly dry until spring re-sprout.

Soil and pot

Caladium 'Carolyn Whorton' grows best in rich, moisture-retentive, free-draining mix. A peat-free or peat-based potting mix loosened with perlite and a little compost. Slightly acidic, humus-rich soil suits it; ensure the pot drains freely to prevent tuber rot. 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 'Carolyn Whorton' sits happiest at around 60-80% humidity and 21-29°C (70-85°F). Loves high humidity; thin leaves crisp at the edges in dry indoor air. Group plants, use a pebble tray or humidifier, and avoid placing near heating vents or draughts. 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 'carolyn whorton' sparingly. Feed every 2-4 weeks through active growth with a balanced liquid fertiliser at half strength. Stop feeding entirely as the plant enters dormancy in late summer or autumn. 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 'carolyn whorton' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Leaf edges browning or crisping — Low humidity or dry air. Raise ambient moisture and keep soil evenly damp during growth.
• Sudden leaf collapse and yellowing in autumn — Usually normal dormancy onset, not death. Reduce water, let foliage die back and store the tuber cool and dry.
• Faded, pale pink markings — Too much direct sun bleaching the colour, or too little light dulling it. Aim for bright indirect light.
• Mushy, soft tuber — Rot from overwatering or cold, wet dormant storage. Keep dormant tubers dry and above 13°C; discard slimy tubers.

Propagation

Divide the dormant tuber in spring, cutting into sections that each retain at least one growth eye (knob). Dust cuts to dry, then pot into warm, barely moist soil to sprout. 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 'Carolyn Whorton' is toxic to pets. ASPCA lists Caladium as toxic to cats and dogs. It contains insoluble calcium oxalate crystals; chewing causes intense oral pain, drooling, pawing at the mouth, vomiting and difficulty swallowing. Keep away from pets and children. 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.
