Welcome to our guide to alocasia care. Alocasias are a genus of plants which include some of my favourites like the alocasia polly and frydek. Their jagged and pointed unique-shaped leaves are the main features of this beautiful genus of tuberous tropical houseplants.
Alocasias need bright but indirect sunlight. Those leaves need a lot of light energy to maintain them, but their beautiful foliage will burn if given too much direct sun.
How Often to Water An Alocasia
Allow the top layer of soil to dry out between watering. Test it with your finger to make sure at least half of your finger is dry when sticking it down into the soil. Go to water it each week and only do so if the top layer is dry. In the winter when the plants grow less they will need much less water, but apply the same technique to test to see if they need any.
Do not feed your alocasia in the winter, but in the summer you can feed them once a month with a general purpose fertilizer. As with all fertilizer feeding, always use a diluted dose on the first time and check for leaf burning/browning.
Use a well-draining peat-based potting compost. You can consider adding some perlite, as alocasias like their environment to be well-draining. They like to be wet but not sitting in water or water logged as this can cause root rot.
When To Repot An Alocasia
If the plant is root bound, then repot your alocasia up a pot size. Do this in spring before the warmer growing months, and plant it up one or two pot sizes.
Alocasias like humidity, or their leaves ill go crispy. They like to misted at watering a the very least, and will like 60%-70% humidity levels if possible, which is like the high end of a household bathroom humidity. So mist them regularly and set up a pebble tray if you can.
Alocasias like the warmer end of household temperatures. Keep them in a warm window, but do not let them get exposed to cold drafts in the winter. Their ideal temperature rand is 18-21°C (64-70°F), so they’ll do well in most households.
Where To Buy An Alocasia
I find the best places to get Alocasias are from specialist plant traders. See our article Rare Plant Shops for more info.
Other Names for Alocasia

Alocasia Care FAQs and Common Problems
Alocasias can be susceptible to pests. The good news is that they get less pests if they are kept humid. If they get spider mites or scale insects they can be treated with a cotton bud and rubbing alcohol to get rid of the bad ones, and if it is only a small issue you can spray the leaves with water and washing up liquid and wipe them down.

Why Is My Alocasia Turning Yellow?
Often leaves turn yellow and can fall off due to not enough water or humidity, which is easy to remedy, But be careful as it can also be a sign of overwatering. Check the soil is dry first before watering. If the soil is wet and the plant is overwatered, then take it out of its soil, let it dry out and then repot it in dry compost.
Brown Patches on Leaves
Alocasia tend to get brown patches from sunburn – be careful of direct sunlight and move the plants back from the light.
Crispy Crunchy Leaves
If the leaves start to go crunchy on your alocasia it is due to a lack of water in the leaves, which is from underwatering or not enough humidity (or both).
Why Is My Alocasia Drooping?
Drooping is a symptom of many issues, the most common one being overwatering. Check the soil and if it is wet, then dry the roots out and repot, then water regularly, but check the top layer of soil is dry before watering again.
