Giant Taro Plant Care

Giant Taro (Alocasia macrorrhizos) belongs to the Araceae family within the Alocasia genus. Giant Taro is native to rainforests of Maritime Southeast Asia, New Guinea, and the Murray Islands group in the Torres Strait. Giant Taro is also known as Elephant Ear, Wild Taro, Upright Elephant Ear.

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

Leaf size: approximately 12 inches.

Alocasia macrorrhizos requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Giant Taro thrives in bright indirect to filtered light light conditions. The optimal light range is 250–1000 lux. Avoid placing Giant Taro in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Alocasia macrorrhizos grows best at temperatures between 65°F and 80°F. Giant Taro 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 Giant Taro to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Giant Taro can be propagated through division, rhizome cuttings. Similar propagation techniques also apply to alocasia odora plant care, which shares the same genus.

Giant Taro 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.

Giant Taro grows outdoors in USDA Zone 9b – 12b. Native to rainforests of Maritime Southeast Asia, New Guinea, and the Murray Islands group in the Torres Strait, Giant Taro is adapted to warm climates. In cooler regions, grow Giant Taro as a houseplant or bring it indoors before the first frost.
