How to Care for the Plant

Water
Keep Alocasia plants moist all year; they are water-loving plants. There is a fine line with these plants. You want to keep the soil moist, but not soggy. They require less water during the winter months because the plant is dormant.
Fertilizer
Alocasias can be heavy feeders, especially large specimens. Feed with liquid fertilizer during the growing season or frequent, small applications of granule fertilizer.
Sunlight
Needs vary from shade to full sunlight, depending on the variety. Ask the grower if the plant is sun-trained. Leaf color tends to be better among plants that grow best with more light.

Soil
Plant in loose, well-drained potting mix or a crumbly loamy soil. Try to let the top few inches of soil become nearly dry before watering. This will help keep it evenly moist. Soggy soil makes the plant susceptible to many fungal infections.
Temperature
Alocasias will start to suffer below 60 degrees Fahrenheit. Some varieties will die back during colder weather and resprout from the rhizome.
Additional
The Alocasia is a very poisonous plant; the leaves contain insoluble oxalate crystals.
