Complete Care & Cultivation Guide

Follow our detailed scientific care guide to keep your White Caladium thriving and gorgeous all year round.

Water thoroughly when the top inch of potting soil feels dry. Keep the soil consistently slightly moist, but never allow it to become waterlogged.

Trim off older, outer leaves near the tuber base using sharp, sterilized scissors to keep the rosette clean and tidy.

Apply half-strength liquid houseplant fertilizer once every 2 weeks during the active spring and summer growing season.

Requires bright, consistent indirect light. Needs this light to survive since the white leaf areas lack chlorophyll; avoid direct sun.

Rich, loose, organic, and highly porous soil. Mix 2 parts peat moss, 1 part potting soil, and 1 part perlite.

Division of the tuber clumps during spring potting. Carefully separate tubers with active growing eyes and plant separately.

Thrives in warm, tropical room temperatures (18°C-29°C). Highly sensitive to cold; enters winter dormancy below 15°C.

Plant tubers 2 inches deep in spring with active buds facing upward. Ensure the pot has ample bottom drainage holes.

Prone to spider mites, aphids, and whiteflies. Maintain high relative humidity and treat immediately with insecticidal soap.

Highly susceptible to tuber rot if kept in cold, soggy soil, and leaf spot if foliage remains wet under poor airflow.

Provide moderate to high humidity (above 50%). Candidum does best in warm, humid spaces, which helps the new heart leaves grow larger.

Common Diseases & Treatment

Tuber Rot

Symptoms: Leaves droop, stems collapse easily, and the underground tuber turns mushy, soft, watery, and decays.

Action: Trim decayed parts of the tuber, apply a fungicide dust, and repot in fresh, highly porous, dry soil mix.

Browning Leaf Margins

Symptoms: The delicate, paper-thin white leaf edges turn crispy dry, brown, and tear easily.

Action: This is caused by low humidity or underwatering. Increase relative humidity above 55% and keep soil evenly moist.

Frequently Asked Questions

Why is my Candidum Caladium leaves turning green?

If kept in too much shade, the plant will produce more green chlorophyll, causing the dark green veins to expand and the white areas to shrink.

How do I care for my Candidum Caladium in winter?

Reduce watering completely as leaves naturally die back in fall. Cut dead foliage, store the pot dry in a warm closet (above 15°C) until spring.

Can I grow Candidum Caladium in direct sun?

No. The delicate, paper-thin white leaves lack protective pigments and will quickly scorch, turn brown, and disintegrate in direct sunlight.

Is Candidum Caladium safe for cats?

No. Like all Caladiums, it contains insoluble calcium oxalates which are toxic to cats and dogs, causing mouth swelling and pain.
