Light: Bright indirect light. Do not place in direct sunlight – this will burn the leaves. It can survive medium light but cannot tolerate low light. When placed in medium light it will grow more slowly.
Temperature: Warm temp 60-80. These plants become dormant with prolonged exposure to temperatures below 60°F (15.6°C) and may drop all of their leaves. Be sure to keep an Alocasia plant away from air conditioners and cold drafts.
Watering: Allow soil to dry out about half way down between waterings. Alocasia can be sensitive to hard tap water. Try using filtered water or leaving water out in a watering can for at least 24 hours before using.
Wet leaves and soggy soil makes an Alocasia plant more susceptible to a variety of fungal infections. Alocasia plants require less water during the winter when it's dormant.
Humidity: Prefers a humid environment. To increase humidity, use a partially filled pebble tray or humidifier. A bathroom or kitchen with appropriate lighting are perfect spots for an Alocasia because these rooms tend to be more humid.
Toxicity: Toxic to pets
Yellowing or spotting on leaves: indicates the plant has been overwatered. Allow the top of the soil to dry out before watering again. Make sure there is no excess water in the saucer or bottom of the planter.
Browning edges: suggests the plant has been underwatered or receiving too much direct sunlight.
Leaves fading or dying in the fall/winter: Alocasia will go dormant in the winter, as temperatures drop and daylight shortens. During this time place the plant somewhere warm (no cold drafts) and reduce watering until it begins to grow again in spring.
