Alocasia Odora Plant Care

Alocasia Odora (Alocasia odora) belongs to the Araceae family within the Alocasia genus. Alocasia Odora is native to East and Southeast Asia. Alocasia Odora is also known as Giant Taro, Elephant Ear.

Alocasia Odora displays a large, upright foliage growth habit, reaching up to 5 ft tall with a spread of approximately 3 ft. Alocasia Odora produces rarely flowers indoors, inconspicuous blooms.

Leaf size: approximately 12 inches.

Water a young or newly planted Alocasia Odora every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Alocasia Odora thrives in bright indirect to filtered light. Avoid placing Alocasia Odora in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Alocasia odora tolerates temperatures of 65–80°F. Alocasia Odora prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich organic mix with perlite and peat moss. Good drainage is essential for Alocasia Odora to prevent waterlogging, which leads to root rot and fungal issues.

Feed Alocasia Odora every 4 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect to filtered light and well-draining, rich organic mix with perlite and peat moss. Avoid low spots where water collects after rain.

Alocasia Odora is suited to USDA Zone 9b – 12b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Alocasia Odora can spread to about 3 ft (0.9 m) and reach about 5 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Alocasia Odora while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Alocasia Odora is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Alocasia Odora can be propagated through division, rhizome cuttings. Similar propagation techniques also apply to alocasia dragon scale plant care, which shares the same genus.

Alocasia Odora is susceptible to spider mites, aphids, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Alocasia Odora grows outdoors in USDA Zone 9b – 12b. It survives winters down to planting zone 9b. Alocasia Odora is native to East and Southeast Asia. In cooler regions, grow Alocasia Odora as a houseplant or bring it indoors before the first frost.
