Below is a general care guide for Alocasia plants which can slightly differ depending on variety.
Light & Temperature
Alocasia plants thrive best in part shade, filtered sun or bright indirect light. Direct sunlight will burn the leaves.
They like protection against strong winds. When placed indoor, make sure the plant is away from drafts or dry air like heaters and air conditioners.
Watering, Humidity & Misting
Allow the top 2-3” of soil to dry out between waterings to ensure the plant is not sitting in water. Alocasia plants like their soil to be a little on the drier side but require high humidity.
For the plant’s optimal growth, frequent misting is recommended. When misting, avoid getting the leaves too wet as it can damage the foliage and weigh the stems down.
Soil and Repotting
Proper Alocasia plant care starts with the soil. They love loose and well-draining potting mix. To keep the plant at a manageable size, you can repot the Alocasia annually into larger pots with fresh soil.
Propagation
Most Alocasia plants can be propagated by rhizome division. Cut a piece of the rhizome and repot it separately. Keep it moist and warm until new growth starts.
Fertiliser
Use a balanced fertiliser formulated for houseplants. Follow the directions on the label of our Down to Earth. organic plant food.
Toxicity
Alocasia plants are toxic if ingested and should be kept out of the reach of children and pets. The base of the stem is more poisonous than the leaves.
Possible Issues
Under the right care and conditions, your plant will grow happy and healthy. But here are some issues you may encounter while caring for an Alocasia:
Spidermites, aphids, scale and mealybugs - A good deterrent is keeping the humidity high.
Brown leaves - This is usually caused by overwatering. Adjust your watering schedule for your Alocasia.
Not overwatered but still have brown leaves - This can be due to soil being too cold. Add a mat or tray underneath the plant or consider relocating it to a less cold area.
Dry, crispy leaves - A sign that humidity is too low. Turn it up a notch by misting more often.
Pale, patchy brown leaves - It can be from too much direct sun or from relocating the plant to a very bright spot too quickly. When moving a plant, do it gradually rather than abruptly.
