Complete Care & Cultivation Guide

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

Water thoroughly when the top 2 inches of soil feel dry. It prefers consistent moisture but hates soggy, waterlogged conditions.

Prune old, naturally yellowing lower leaves at the stem base using sharp, sterilized bypass loppers. Wear gloves to avoid sap.

Apply balanced liquid houseplant food at half strength once every 4 weeks in spring/summer to support its rapid, massive growth.

Thrives in bright indirect light and can tolerate direct morning sun. Avoid hot direct afternoon sun which scorches massive leaves.

Rich, well-aerating organic mix: 50% peat moss, 35% organic compost/bark, and 15% coarse perlite. pH 5.6-7.0.

Easily propagated by separating offsets or offshoots from the woody trunk base, or growing sprouted corms in warm peat.

Warm temperatures (18°C-32°C). Extremely cold-sensitive; protect from frost and temperatures below 12°C.

Requires large, heavy pots to support its massive, wide-spreading canopy. Repot every 1-2 years into a pot 2-3 inches wider.

Susceptible to spider mites, thrips, and aphids. Clean the massive leaves regularly and apply organic insecticidal soap spray.

Vulnerable to bacterial blight and root rot if soil is heavy and overwatered in containers without drainage.

Wipe the massive leaves monthly with a damp cloth to remove dust. This keeps the plant looking glossy and maximizes photosynthesis.

Common Diseases & Treatment

Bacterial Blight

Symptoms: Wet, rapidly spreading dark spots on leaves that emit a rotting, fishy odor.

Action: Cut off infected foliage immediately, disinfect tools, reduce humidity, and avoid wetting leaves.

Root Rot

Symptoms: Leaves turn soft yellow and stems droop; roots turn black and mushy; base trunk turns soft.

Action: Repot instantly in a fresh, highly porous, fast-draining potting soil, trimming away soft decayed roots.
