Alocasia Portora Light Needs

Bright indirect sunlight is ideal. When they get big they will tolerate some direct early in the morning, but be careful not to burn the leaves. They can also do well in medium indirect sunlight too. A bit back from a south facing or in a west facing window is ideal.

Clean the leaves every now and again from dust, which will allow thm to take in as much sun as possible.

How Often To Water

Check the soil weekly, and only water it if the soil is dry almost all the way down. Keep them moist, consistently, but not soaking. If in doubt, under water it as root rot can take hold quite quickly. When you do water it soak it, and let the water drain off completely, don’t leave any say in the saucer or tray under the plant. Use filtered water and leave it over night, as they can be sensitive.

They will need much less water in the winter months and growth can slow right down, so make sure you always check the soil before watering.


Use a well diluted balanced feed monthly in spring and summer to encourage growth. They’ll be ok if you don’t feed them but should grow quicker if you do.

When to Repot

Check their roots yearly in Spring and pot them up a size if they are crowded. They can grow quite quickly.

Tip: Don’t be worried if they shed an old leaf when a new one grows. A lot of people worry when they shed a leaf, but it is totally normal when juvenile for an older leaf to die off as a new one grows, the plant may only support three leaves for example. When the plant matures and the trunk gets bigger it will support more leaves.


Aim for 60%, their leaves like it humid. They really like to be humid, use pebble tray or at least keep them with other plants to maintain a good level.


16-27°C (61-81°F) is ana ideal range in the day, and down to 10°C (50°F) at night.
