Alocasia Odora Soil

Alocasia Odora will thrive in a water-retentive, well-draining, rich soil. You may make a perfect soil mix by combining commercial potting mix with compost, peat moss or coco coir, and perlite. 

Alocasia Odora Fertilizer

Alocasia Odora, being a large, quick-growing plant, will benefit from a feeding biweekly during the warm growing season of spring and summer. Select a balanced, liquid fertilizer indicated for houseplants and dilute to 50%. Feed from March to September. Do not feed during the late fall and winter. Ensure that you do not overfeed, as this may lead to excess salt buildup in the soil, which may cause damage to your plant due to fertilizer burn. 

Alocasia Odora Watering

Alocasia Odora likes to remain consistently moist but not oversaturated with soil. Rewater your Alocasia after the top 2-3 inches of soil has dried. Watering frequency should be reduced in late fall and winter during dormancy.

Alocasia Odora Light Requirements

Alocasia Odora will grow best if kept in bright indirect light, such as from an eastern-facing window. While this Alocasia plant may tolerate lower light conditions, it will cause growth to slow down, foliage to become smaller, and leaves to become lighter in color. Alternatively, too much direct sunlight will lead to leaf scorch. 

Alocasia Odora Temperature & Humidity

As a tropical plant, Alocasia Odora will like to remain in a warm and humid environment. Alocasia Odora prefers to be kept between 65-80 degrees. You may aid the growth of your plant by increasing the humidity level of its growing environment. This may be done by installing a humidifier or pebble tray. 

Repotting Alocasia Odora

Alocasia Odora will not need to be repotted often. It does not like to be moved and wants to remain slightly rootbound. However, it is time to repot when roots are seen coming out of the drainage holes. When selecting a container, choose a pot that is around 2-4 inches larger than the previous container. Repotting should ideally be done in early spring. Propagation can quickly be done at the same time. To repot, remove the plant from its container, minimally touching the roots. Insert the root ball into the new container, refresh the soil, tamp slightly, water thoroughly, and place in indirect light.

Alocasia Odora Maintenance & Pruning

Periodically, you should maintain the aesthetic of your Alocasia plants by removing any damaged, discolored, or dead leaves using sharp, clean shears. 

Alocasia Odora Propagation

Alocasia Odora may be easily propagated through rhizome division. It is best to do propagation in spring while repotting. Remove the mother plant from its container and separate tubers from the mother plant to propagate. Tubers should be separated and placed into their own container. Water the newly planted plantlets thoroughly and place them in indirect light in a warm environment.
