Ideally, Alocasias should be kept in bright locations with exposure to indirect, filtered light. The plant should not be kept in full direct sunlight as this can cause its leaves to burn. Your Alocasia will do well even in medium light but it is not very tolerant of low light, so try to keep it in an appropriate spot.
Alocasias prefer their soil to be moist, but not overly wet or soggy. Make sure to water it regularly as it is not a drought-resistant plant. It can survive missing the occasional watering session, but allowing the soil to dry too much over time can lead to the leaves turning brown at the fringes and tips. Do check that the soil is not too soggy as it can lead to root rot which can harm the plant.
The Alocasia does best in environments with high humidity. Lightly mist the leaves on a regular basis or use a pebble tray to ensure the plant has enough humidity. Giving it regular, mild temperature showers in your bathroom shower stall or with spray attachments will help it flourish. This humidity-lover will do best when placed in your bathroom or kitchen as those spots tend to be quite humid.
Alocasias do best between 60-85 degrees Fahrenheit, so you should keep indoor temperatures above 60 degrees to keep the plant warm. You should place them in spots that don’t face drafts or cross winds and avoid rapid temperature changes.
They do best with general houseplant / indoor plant fertilizers that are fortified with iron; they should be fed once a month during spring and summer time. Fertilizers are not required during winter as plant growth is slow during this time. Make sure to apply fertilizer only to damp soil, it can burn the roots of the plant if applied to dry soil.
They can be slightly toxic to pets and humans – if consumed, they can cause some irritation in the mouth and stomach, and potentially nausea and/or vomiting.
In winter, Alocasias are mostly dormant. During this time, you should place your Alocasia in a warm spot and reduce the frequency of its watering sessions (but ensure that the soil does not dry out). When it is spring, you will notice the plant become lively and start growing again.
