Alocasia Macrorrhiza Care: In A Nutshell
Alocasia macrorrhiza is a rhizomatous evergreen perennial plant that is native to tropical areas of Asia. It’s a decorative yet dangerous plant, which is toxic to animals. It likely originated in Sri Lanka and India and is found through Southeast Asia into the islands of Indonesia.
This plant is primarily grown for its remarkable foliage. Its huge arrowhead-shaped leaves can reach an astounding 3 to 6 feet long and 2 to 4 feet across! The prominent veins and ruffled edges add great texture and visual interest.
Unlike related Alocasia and Colocasia species, Alocasia macrorrhiza leaves stand fully upright rather than drooping down. When mature, the plant can reach 12-15 feet tall and 6-8 feet wide. Truly a giant in the garden!
Everything About Alocasia Macrorrhiza Care
While stunning, Alocasia Macrorrhiza does require some specific care in order to thrive. Here are its key needs.
Light
Bright, indirect light is best for Alocasia Macrorrhiza. It flourishes with about 6 hours of sunlight per day. Direct hot sunlight can scorch the leaves, so provide dappled light or afternoon shade. Indoors, place near an east or west-facing window.
Water
These tropical broadleaf perennials require consistently moist, fertile soil. Water thoroughly whenever the top few inches become dry. Use tepid water rather than cold. In winter, reduce watering frequency but don’t let soil dry out completely.
Temperature & Humidity
Warm temperatures between 65°F to 85°F are ideal. High humidity is also beneficial—at least 50% relative humidity. Use a pebble tray or humidifier nearby. Move plants outdoors in summer if possible. Bring indoors before temps dip below 60°F.
Soil
Alocasia macrorrhiza thrives in loose, organic-rich soil that retains moisture but drains well. Amend heavy clay or sandy soil with compost. Maintain a pH between 5.5 and 7.5.
Fertilizer
Apply a balanced liquid fertilizer every 2-4 weeks during the growing season. Reduce frequency in winter. Or use slow-release pellets in spring.
Propagation
These plants are easy to propagate! Simply divide rhizomes or take stem cuttings in spring or summer. Place cuttings or rhizome sections in water or damp potting mix. Keep warm and moist until new growth emerges.

What About Repotting and Pruning?
Repot young plants annually in early spring until they reach maturity. Older Alocasia macrorrhiza only needs repotting every 2-3 years—or whenever roots fill the container. Divide congested rhizomes at repotting time.
Remove drooping, yellowed leaves and stems as needed to keep plants looking tidy. Wipe leaves with a damp cloth to remove dust.
Where’s the Best Place to Grow Alocasia Macrorrhiza?
Giant Taro makes a big statement in the garden as a focal point or specimen plant. It also thrives in a large planter or koi pond. Provide a sheltered spot protected from wind, which can shred the large leaves.
For indoor growing, place near a bright window out of direct sun. Humidity may need to be boosted with a humidifier. Rotate the plant periodically so all sides receive adequate light.
Any Common Pests or Diseases to Watch For?
Alocasia macrorrhiza is prone to spider mites, scale, mealybugs, and aphids. Check the undersides of leaves and stem joints for small insects. Treat with horticultural oil or insecticidal soap sprays. Improve air circulation to prevent problems.
Leaf spot diseases may occur in humid conditions. Avoid wetting foliage when watering and allow it to dry out between waterings. Remove affected leaves promptly.
Is Alocasia Macrorrhiza Toxic?
Yes, Alocasia macrorrhiza contains calcium oxalate crystals and other compounds that make the plant toxic. Take care to keep pets and small children away from the plants. Wear gloves when handling, as contact dermatitis is possible.
If ingested, the plant irritants cause swelling, burning, and other distress. Seek medical attention if concerning symptoms develop.
