Complete Care & Cultivation Guide

Follow our detailed scientific care guide to keep your Black Magic Elephant Ear thriving and gorgeous all year round.

Prefers wet, highly saturated soil. Water frequently; it is a water-loving plant that can even grow in shallow water or bog gardens.

Prune naturally yellowing lower leaves at the base in spring using sharp sterilized shears. Wear gloves as the sap can cause skin irritation.

Feed monthly from spring to late summer with a balanced organic liquid foliage food diluted to half strength.

High-intensity bright indirect light to full sun. Direct sun intensifies the charcoal-black color; in shade, leaves revert to dull green.

Rich organic moisture-retaining mix: 50% peat moss, 30% organic compost/loam, and 20% perlite/vermiculite (pH 5.5-7.0).

Easily propagated by separating underground runners (tubers) or offsets during spring repotting. Sprout runners in warm moist peat.

Warm tropical temperatures (18°C-35°C). Extremely cold-sensitive; protect from frost and temperatures below 12°C.

Requires large, heavy pots to anchor its massive canopy. Ensure pots have drainage unless grown in bog gardens.

Susceptible to spider mites in dry air, and occasionally aphids or caterpillars. Clean foliage regularly.

Vulnerable to fungal leaf blight under highly humid and poorly ventilated conditions, and tuber rot if kept cold and wet.

To get the deepest black leaf color, provide plenty of bright direct morning sunlight. Direct sun is highly beneficial for Colocasias.

Common Diseases & Treatment

Fungal Leaf Blight

Symptoms: Small water-soaked tan or brown spots expand on the large black leaf surfaces under high humidity.

Action: Prune infected leaves, improve airflow, avoid overhead watering, and spray with organic copper fungicide.

Tuber Rot

Symptoms: Leaves yellow and collapse; underground tuber turns soft, mushy, and rots under cold, wet winter conditions.

Action: Prune rotten tuber parts, keep dry, and store in warm peat until fresh growth sprouts.
