How to grow Caladium ‘White Queen’ indoors

• Light: Give it bright filtered light. Gentle morning or evening sun can be introduced gradually.
• Temperature: Keep it warm. Protect the leaves and tuber from cold draughts, cold window glass and other cold conditions.
• Water: When the plant is growing, water once the top of the mix begins to dry and the pot feels lighter. Water thoroughly and let the excess drain.
• Humidity: Keep it away from hot, dry air such as heating vents, and keep some airflow around the leaves.
• Potting mix: Use a loose, airy mix that drains freely and still holds some moisture.
• Feeding: Feed with a balanced houseplant fertiliser while new leaves are growing, following the label.
• Rest: If the leaves yellow and die back, water less. Return to normal watering when new shoots appear.
• Repotting and propagation: Repot when the tubers crowd the pot or the mix becomes compacted. To propagate, divide a mature tuber so each piece has a healthy bud.
• Safety: Caladium tissue contains calcium oxalates that can irritate the mouth, skin and eyes. Keep it out of reach of children and pets, and wash your hands after handling damaged tissue.

Common problems and solutions for Caladium ‘White Queen’

• Wilting with dark or soft roots: Pythium can cause root rot. Inspect the roots and tuber. Cut away the rot with a clean tool until you reach firm, healthy tissue. Discard everything you remove, then improve the drainage.
• Tuber lesions or spreading rot: Fusarium and white mould can damage the tuber. Separate the plant. If the damaged area is small, cut away the rot with a clean tool until you reach firm, healthy tissue. Discard everything you remove. Discard extensively soft or rotten tuber tissue.
• Water-soaked spots that turn brown: Bacterial blight is one possible cause. Separate the plant, use clean tools, remove badly affected foliage and keep leaves drier during watering.
• Stippling, silvering or webbing: Inspect for mites and thrips and separate the affected plant. If treatment is needed, use a product labelled for indoor ornamental plants and follow the label. Repeat treatment only as directed on the label.
