Alocasia Odora Care Requirements

Light
Good news for those with limited light – the Alocasia odora is a shade lover. It thrives in partial to full shade outdoors and should be kept in medium to bright indirect light indoors.
Soil
Alocasia odora prefers soil that is rich, moist, and well-draining. When grown in containers, mix potting soil with perlite and orchid bark for nutrients and aeration. In the garden, avoid clay soils and improve soil quality with fresh potting soil, perlite, and sand.

Temperature and Humidity
Alocasia odora thrives in warm temperatures and high humidity, hardy in USDA zones 9 to 11. For colder climates, grow it in containers or as a houseplant and protect it from cold temperatures. Maintain humidity above 60% for vigorous growth.
Fertilizer
Regularly fertilize Alocasia odora during the spring and summer with a balanced liquid fertilizer or slow-release option. Avoid fertilizing in the fall and winter when the plant is dormant.
Propagating Alocasia Odora
The most common method for propagating Alocasia odora is by division. As the plant matures, it naturally produces new corms that can be divided to control size or create new plants.
Potting and Repotting Alocasia Odora
When growing Alocasia odora in a container, repot it every one to two years in a slightly larger pot. Refresh the potting soil and avoid breaking too many roots. Enlist help for larger plants.
Overwintering Alocasia Odora
To overwinter Alocasia odora corms, cut off foliage in the fall, dig up the corms, and dry them out for storage. Rehydrate corms before planting in the spring in a shady location with well-draining soil.
