How to care for your Elephant Ear

Everything you need to keep your Elephant Ear healthy: watering, light, humidity, feeding, repotting and pruning.

Alocasia amazonica, also known as Alocasia × amazonica, is a tropical hybrid prized for its dramatic shield-shaped leaves. The striking contrast between the very dark green leaf blade and the silvery veins creates an absolutely remarkable visual effect. This plant demands conditions close to its tropical origins: consistent warmth, high humidity, and bright light without direct sun. In winter, it may enter dormancy and lose its leaves, which is a natural phenomenon — simply reduce watering and wait for spring to see it resprout.

Watering your Elephant Ear

Every 5 days

Keep soil consistently moist but not soggy. Water when the top 2 cm dries. Use filtered water at room temperature. Never let the plant sit in standing water.

How to know it needs water

Top 2 cm of soil feels dry
Leaves begin to droop
Water droplets appear on leaf tips (guttation — normal but indicates adequate moisture)

How much light a Elephant Ear needs

Bright indirect light

Bright indirect light is essential. No direct sun which scorches the leaves. Insufficient light causes leggy growth and loss of dramatic leaf markings.

Direct sun tolerated: No direct sun
Orientations that suit it: North, North-east, East, North-west, West, South-east, South-west

Humidity and misting

60–80 %

60–80% Requires very high humidity. Mist daily or use a humidifier. Group with other plants to raise ambient humidity. Brown leaf edges indicate too-dry air.

Feeding and fertiliser

Every 14 days

Feed every two weeks during the active growing season at half strength. Stop feeding entirely during winter dormancy. Resume in spring when new growth appears.

Recommended feed: Balanced liquid fertilizer (20-20-20) · 2-1-2

Repotting your Elephant Ear

Every 12 months

Use a rich, well-draining aroid mix with perlite, orchid bark, and coco coir. Go up one pot size. Handle the bulbous rhizome carefully. Separate offsets if present.

When: Spring
Potting mix: All-purpose potting mix
Mix in: perlite, coco fibre, pine bark

The tell-tale signs

Roots growing out of drainage holes
Corms visible at the soil surface
Plant dries out within a day of watering

Pruning your Elephant Ear

Year-round as needed to remove dying or yellowing leaves. Cut dead or damaged leaves at the base of the petiole with clean scissors. Alocasias naturally shed older leaves as new ones grow — this is normal. Remove spent foliage promptly.

Through the year

Watering is not set once and for all: it follows the light and the growth. Allow 9 days between waterings in the depth of winter, against 4 in the growing season.

Toxicity

Contains calcium oxalate crystals throughout the plant. Highly toxic if ingested, causing severe oral burning, swelling, and difficulty breathing. Keep away from children and pets.

Good to know

Despite its name, Alocasia amazonica is not from the Amazon — it is a hybrid created by a Florida nurseryman in the 1950s whose nursery was called 'Amazon Nursery'.
Alocasias can enter dormancy in winter, losing all their leaves, but they resprout in spring from their underground rhizome.
