Alocasia cucullata, sold as Chinese taro or Buddha’s hand, is the easy-going little cousin of the giant elephant ears. The Royal Horticultural Society (RHS) describes it as a tender perennial up to about 1 m tall, with upright stems branching at the base and glossy, broadly oval to heart-shaped leaves. Alocasia cucullata care is simpler than most alocasias: bright filtered light, free watering and regular feeding from spring to autumn, then much less water in winter, and warmth above 12 °C (54 °F).
Alocasia Cucullata Care Snapshot

| Humidity | Raised: pot on a tray of moist gravel | Very dry air |
| Compost | Peat-free houseplant compost with added grit | Dense mix that stays soggy |
| Water | Freely spring to autumn; minimal in winter | Wet compost in winter |

What Is Alocasia Cucullata?
Plants of the World Online (Kew) gives its native range as Sri Lanka and the Himalaya to southern China and Indo-China, growing mainly in the wet tropical biome, and lists places it has been introduced, including Japan, Costa Rica and the Cook Islands. It was first described as Arum cucullatum in 1790. The species name cucullata means “hooded”.
Compared with the giant Alocasia macrorrhizos, it is compact: the RHS gives a height and spread of 0.5 to 1 m. Its leaves are glossy green and smooth, very different from the dark, velvety Alocasia Black Velvet or the patterned Alocasia Polly. The RHS notes it rarely produces its pale yellow spathe flowers.
Care Through the Year
- Spring to autumn: the RHS says to water freely and apply a general liquid fertilizer every 2 to 3 weeks. This is the time to repot or divide.
- Winter: reduce watering to a minimum and keep the plant above 12 °C (RHS). Growth slows, so the compost dries much more slowly; soggy compost in winter is the main cause of rot.
The RHS rates it H1B, which means it can go outdoors in summer in mild areas; bring it back in well before nights turn cold. UF/IFAS notes that freezing temperatures kill alocasia foliage.
Light, Temperature and Humidity
Light. The RHS recommends bright, filtered or indirect light indoors and an east- or west-facing aspect, and UF/IFAS says alocasia houseplants need bright, indirect light. A spot near an east window, or back from a sunnier window behind a sheer curtain, suits it. Pale, scorched leaves mean too much sun; stretched stems and small leaves mean too little.
Temperature. Keep it warm in the growing season and above 12 °C (54 °F) in winter (RHS). Avoid cold drafts and cold glass, which can cause yellowing and leaf drop.
Humidity. The RHS suggests standing the container on a tray of moist gravel or pebbles to provide humidity. In very dry heated air, a humidifier helps more, and dry air also encourages spider mites.
Soil, Watering and Feeding
Compost. The RHS recommends peat-free houseplant compost with added horticultural grit. UF/IFAS describes alocasias as liking rich, moisture-retentive soil. In a pot, the balance is moisture-retentive but free-draining: a good houseplant compost with grit or some bark, and always a pot with drainage holes. See our aroid soil mix guide.
Watering. Water freely in spring and summer (RHS), soaking the compost and letting the excess drain, then water again when the top few centimetres feel dry. In winter, water only enough to stop the compost drying out completely. UF/IFAS lists root rot from overwatering as one of the problems that can occur.
Feeding. A general liquid fertilizer every 2 to 3 weeks from spring to autumn (RHS). Stop in winter. Too much feed builds up salts and browns the leaf edges.
Repotting. Repot in spring when the clump fills its pot, moving up one size.
Propagation
The RHS recommends division in spring or summer, or stem cuttings in spring. Division is easiest because the plant branches at the base and forms clumps:
- Wear gloves: the RHS warns the plant is a skin and eye irritant.
- Slide the plant out of its pot and find offsets or stems with their own roots.
- Separate them with a clean knife, keeping roots on each piece.
- Pot each division in fresh compost at the same depth, water lightly, and keep it warm and in bright indirect light until new leaves appear.
Is Alocasia Cucullata Toxic to Pets?
Toxic to cats, dogs and horses
The ASPCA lists alocasia (elephant’s ear) as toxic to dogs, cats and horses because of insoluble calcium oxalates, with signs including oral irritation, pain and swelling of the mouth, tongue and lips, excessive drooling, vomiting (not in horses) and difficulty swallowing. The RHS lists A. cucullata as toxic if eaten and a skin and eye irritant, and UF/IFAS rates alocasia toxicity as medium severity, with possible contact dermatitis. If a pet chews it, call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435.

Common Problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Yellowing lower leaves, wet compost | Overwatering, especially in winter; root rot | Water less; check roots; repot rotten plants into fresh compost |
| Yellowing or drooping after a cold spell | Cold drafts or temperatures below 12 °C | Move to a warmer spot away from cold glass |
| Brown, crispy edges | Dry air or fertilizer salts | Gravel tray or humidifier; flush the pot; feed less |
| Pale or scorched patches | Direct sun | Filtered or indirect light |
| Fine speckling, webbing under leaves | Glasshouse red spider mite (RHS) | See our spider mite guide |
| White cottony clusters | Mealybugs (RHS) | See our mealybug guide |
| Leaves dying back in winter | Natural slowdown, sometimes partial dormancy | Keep barely moist and warm; new leaves return in spring |
Sources: RHS; UF/IFAS FPS 33. Fixes are general practice.
The RHS describes A. cucullata as generally disease-free, so most problems come back to watering, cold or pests. If roots have turned brown and mushy, see our root rot guide.

Frequently Asked Questions
How do you care for Alocasia cucullata?
Give it bright, filtered light, peat-free houseplant compost with added grit, free watering and a general liquid feed every 2 to 3 weeks from spring to autumn, and minimal water in winter while keeping it above 12 °C, as the RHS recommends.
How big does Alocasia cucullata get?
The RHS gives a height and spread of 0.5 to 1 m, reached in 2 to 5 years, which makes it one of the more compact alocasias.
How often should I water Alocasia cucullata?
Freely in spring and summer, whenever the top few centimetres of compost dry, and only minimally in winter. Never leave the pot standing in water.
Why are my Alocasia cucullata leaves turning yellow?
Usually overwatering, especially in winter, or cold. Check the compost and roots, water less, and keep the plant above 12 °C away from drafts. An occasional old leaf yellowing is normal.
Can Alocasia cucullata go outside?
In summer, in a sheltered spot out of hot sun. The RHS rates it H1B, meaning it can be grown outside in summer; bring it in before temperatures drop toward 12 °C. Frost kills the foliage.
Is Alocasia cucullata toxic to cats?
Yes. The ASPCA lists alocasia as toxic to cats, dogs and horses because of insoluble calcium oxalates.
