Alocasia macrorrhizos, commonly known as the giant elephant ear or giant taro is a stunning plant with massive lush green leaves. Alocasias are members of the aroid family of plants and were native to tropical Asia. They thrive in warm humid environments. Alocasias aren't the easiest plants to care for, so we do not recommend them for beginners. Please read the information below for more information. 

Alocasias are toxic if eaten and are skin and eye irritants. Keep out of reach of children and pets.

Light requirement: Part sun/part shade and Bright indirect sunlight

Water requirement: Medium

Watering frequency: When the top 5cm of the potting mix is dry to the touch. Ensure the potting mix does not dry out completely to prevent leaf browning. On the other hand, similar to most potted plants, overwatering can cause root rot and pest problems. To keep your Alocasia happy, ensure you are watering it just right.

Soil: Rich, consistently moist but well-draining.

Skill level: Expert

Growth rate: Fast

Suitable for containers: Yes

More info: 1) Humidity: Alocasias are originally from tropical and sub-tropical regions and thrive in warm, humid conditions. Low humidity can cause leaf browning. Alocasias love about 70% humidity, but can be happy with 60% humidity - the humidity that Sydney more or less has throughout the year except for July, August and September. Increasing humidity levels with a humidifier or a pebble tray with water will make your plant healthier and keep the leaves looking lush.
2) Winter: Alocasias are not frost tolerant. Either bring them indoors during winters or plant them in an area that is protected from strong winter winds and mulch well. During winter, the leaves might die back. If this happens, reduce watering and feeding and the plant might grow back in spring!
