Voodoo Lily Plant Care

Voodoo Lily (Amorphophallus mekongensis) belongs to the Araceae family within the Amorphophallus genus. Voodoo Lily is native to Vietnam & Laos. Voodoo Lily is also known as Devil's Tongue.

Voodoo Lily displays a large, solitary leaf growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Voodoo Lily produces unique, foul-smelling inflorescence.

Leaf size: approximately 36 inches.

Water a young or newly planted Voodoo Lily 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.

Voodoo Lily thrives in bright indirect to partial shade. Avoid placing Voodoo Lily in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Amorphophallus mekongensis tolerates temperatures of 65–80°F. Voodoo Lily prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich organic soil with added perlite and peat moss. Good drainage is essential for Voodoo Lily to prevent waterlogging, which leads to root rot and fungal issues.

Feed Voodoo Lily every 6 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 partial shade and well-draining, rich organic soil with added perlite and peat moss. Avoid low spots where water collects after rain.

Voodoo Lily is suited to USDA Zone 10b – 11b.

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.

Voodoo Lily can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Voodoo Lily 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.

Voodoo Lily is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Voodoo Lily can be propagated through offsets, seeds. Similar propagation techniques also apply to toad lily plant care, which shares the same genus.

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

Voodoo Lily grows outdoors in USDA Zone 10b – 11b. It survives winters down to planting zone 10b. Voodoo Lily is native to Vietnam & Laos. In cooler regions, grow Voodoo Lily as a houseplant or bring it indoors before the first frost.
