Light
Alocasia Polly grows best with bright, indirect light, such as from an east-facing window out of direct sun. In brighter spaces, sheer curtains can help filter harsh sunlight and protect the plant's leaves from sunburn. Too much light can also cause leaves to look washed out and pale.
 
Soil
Plant your alocasia Polly in a rich, well-drained potting soil that contains organic matter to help retain moisture.
 
Water
Water your alocasia Polly so that the soil stays consistently moist. This can be a delicate balance, as soggy soil can lead to root rot, but dry soil can trigger dormancy in the plant. Avoid getting the leaves wet while watering to minimize the risk of plant disease. In winter, when the plant is not actively growing, water just when the top of the soil is beginning to dry out.
 
Temperature and Humidity
Alocasia Polly needs temperatures above 65 degrees or so to thrive. Lower temperatures can damage or kill the plant, so keep it out of cold spaces and drafty areas. A warm space with high humidity provides an ideal climate, making this a great bathroom plant. You can also group alocasia Polly in the same space with other humidity-loving tropicals and run a humidifier to add moisture to the air.
 
Fertilizer
Fertilize your alocasia Polly regularly during the growing season. Begin feeding the plant with organic houseplant fertilizer diluted to half strength every two weeks in spring, then stop fertilizing at the end of summer. Start this routine back up when spring comes around again.
