Care at a glance

Light

Bright but filtered. Alocasia Jacklyn burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Give it bright, filtered light for 6-8 hours a day, ideally near an east or filtered south/west window. Direct midday sun scorches the thin lobed leaves, causing crispy brown margins and bleaching; too little light causes stretching and weak new growth. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering alocasia jacklyn: roughly every 5-9 days in active growth; less in winter. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Water when the top 1-1.5 inches (3-4 cm) of mix feels dry, then water thoroughly and let it drain fully. This cultivar is very sensitive to overwatering and rhizome rot, so never leave the pot sitting in water and reduce watering sharply if it goes dormant in winter.

Soil and pot

Alocasia Jacklyn grows best in chunky, airy, fast-draining aroid mix. Use a porous blend such as orchid bark, coco coir or peat, and perlite (with a little worm castings) so roots get plenty of oxygen and excess water drains freely. Keep the bulb/rhizome at or above the soil surface and always use a pot with drainage holes. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Alocasia Jacklyn sits happiest at around 60-80%+ humidity and 18-28°C (65-82°F). Loves consistently high humidity to support its thin, lobed leaves; below about 50% you'll see crispy edges and a higher risk of spider mites. Run a humidifier nearby, group with other plants, or use a pebble tray (pot base above the waterline). If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed alocasia jacklyn sparingly. Feed monthly during spring and summer with a balanced liquid houseplant fertiliser diluted to about half strength. Stop feeding entirely in autumn and winter, especially if the plant slows or goes dormant, to avoid salt buildup and root burn. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on alocasia jacklyn in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Yellowing or drooping leavesMost often overwatering or soggy, poorly draining mix; let the top 1-1.5 in dry out, ensure the pot drains freely, and check the rhizome for soft, rotted spots.
  • Crispy brown leaf edgesCaused by low humidity, dry air, or inconsistent watering. Raise humidity to 60%+ with a humidifier or pebble tray and keep watering even.
  • Scorched or bleached patchesDirect midday sun damages the thin lobed leaves. Move to bright indirect light or filter the sun with a sheer curtain.
  • Spider mites and other pestsSpider mites, mealybugs, and scale thrive in dry air. Keep humidity up as prevention; treat infestations promptly with insecticidal soap or neem oil and wipe leaves regularly.
  • Sudden leaf drop / dormancyIn winter, low light and temperatures below ~60°F (15°C) can trigger dormancy where it sheds leaves into the corm. Cut back watering, stop fertilising, keep it warm, and wait for spring regrowth.
  • Root or rhizome rotCold, wet, airless soil rots the corm. Use a chunky, fast-draining mix, keep the bulb at the surface, and never let the pot stand in water.

Propagation

Propagate by division during spring or summer when actively growing. Unpot the plant, gently expose the root ball, and separate offsets or rhizome/corm sections that each have their own roots using a sterilised blade. Pot divisions into fresh, well-draining mix and keep warm, humid, and in bright indirect light until established. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Alocasia Jacklyn is toxic to pets. The ASPCA lists Alocasia spp. as toxic to cats, dogs, and horses due to insoluble calcium oxalate crystals in all parts of the plant. Chewing can cause oral irritation, intense burning and swelling of the mouth, tongue and lips, drooling, vomiting, and difficulty swallowing. Keep well out of reach of pets and children. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Alocasia Jacklyn care — frequently asked questions

What is the common name for Alocasia 'Jacklyn'?

Alocasia 'Jacklyn' is most commonly called Alocasia Jacklyn, but it is also known as Alocasia Jacklyn, Alocasia Tandurusa, Alocasia sp. Sulawesi, Jewel Alocasia. The names refer to the same species, so care instructions for Alocasia Jacklyn apply identically to anything sold as Alocasia Tandurusa.

How much light does alocasia jacklyn need?

Alocasia Jacklyn grows best in bright indirect light (just back from a sunny window). Give it bright, filtered light for 6-8 hours a day, ideally near an east or filtered south/west window. Direct midday sun scorches the thin lobed leaves, causing crispy brown margins and bleaching; too little light causes stretching and weak new growth.

How often should I water alocasia jacklyn?

Water alocasia jacklyn roughly every 5-9 days in active growth; less in winter. Water when the top 1-1.5 inches (3-4 cm) of mix feels dry, then water thoroughly and let it drain fully. This cultivar is very sensitive to overwatering and rhizome rot, so never leave the pot sitting in water and reduce watering sharply if it goes dormant in winter. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is alocasia jacklyn toxic to cats and dogs?

Alocasia Jacklyn is toxic to pets. The ASPCA lists Alocasia spp. as toxic to cats, dogs, and horses due to insoluble calcium oxalate crystals in all parts of the plant. Chewing can cause oral irritation, intense burning and swelling of the mouth, tongue and lips, drooling, vomiting, and difficulty swallowing. Keep well out of reach of pets and children.

What USDA hardiness zone does alocasia jacklyn grow in?

Alocasia Jacklyn is rated for USDA zone 10-12 (frost-tender; grown as a houseplant elsewhere). Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
