Alocasia

Elephants Ear Plants

Alocasia or ‘elephant ear plants’ are fantastic foliage plants with huge leaves up to 1m long. Alocasia macrorrhizos is known as the giant taro, giant elephant ear or upright elephant ear and is a popular species. Alocasia x Amazonica ‘Poly’ is pictured right.

They do differ from the close relative Colocasia, mainly in the direction the leaf faces, which is upwards, Colocasia leaves generally face downwards.

How To Grow Alocasia – Basic Care

• Alocasia pefer some protection from direct sunlight this is a plant that grows well in a part shaded but light position.
• A warm climate and a well drained potting mix is best. All species are really a tropical plant that require warmth and humidity throughout the year. All varieties do well as potted plants indoors.
• Watering – Water regularly, usually once a week during the growth period, spring through summer. Always allow the soil to dry a little between waterings and never allow the plant to sit in saucers of water.
• Fertilizer – Use a liquid fertilizer every 4 weeks from spring through summer. Cut back on fertilizer during winter months.
• Toxicity – Like many plants Alocasia are toxic to cats and dogs as well as humans if eaten.
• Improving humidity – Fill a saucer with pebbles and then with water. Sit the pot on top of the pebbles, raised above the water. Mist spraying is a short term fix for humidity best used sparingly and then during hot dry periods.

Problems

• Yellow Leaves – Usually due to overwatering, or excessive exposure to light. Yellow leaves can also be caused by over fertilizing.
• Drooping Leaves – Again caused by overwatering and root rot. Also caused by under watering (wilting)
