Alocasia Jacklyn
The Alocasia Jacklyn (Alocasia tandurusa) is one of the most dramatic-looking aroids available — and its name tells you exactly why. Tandurusa comes from the Indonesian tanduk rusa, meaning deer antlers — a direct reference to the deeply, irregularly lobed leaf margins that give each leaf its wild, sculptural silhouette. The leaves are vivid green with contrasting dark veins that bleed softly into the surrounding blade, creating a two-toned effect that appears almost iridescent when light passes through. The petioles are streaked in purple and green — ornamental even before the leaf opens. A fast grower that can reach 90–120 cm indoors, it fills a space quickly and makes an immediate statement.
Light
▾
Medium to bright indirect light. East or west-facing window is ideal. Tolerates grow lights well. No direct sun — scorches the leaves and washes out the two-toned green colouring. In low light, growth slows and the vivid green fades.
Watering
▾
Allow the top half of the soil to dry before watering. Water thoroughly then empty the saucer. Filtered or rainwater preferred. Check every 7–10 days in summer, every 14 days in winter. Root rot from overwatering is the most common cause of decline.
Humidity
▾
60–80% preferred, though it tolerates average indoor humidity (40–50%) reasonably well — more adaptable than many aroids. A humidifier or pebble tray helps in dry rooms. Keep away from AC vents and cold drafts.
Growing Media
▾
Well-draining aroid mix: 40% potting soil, 25% perlite, 20% orchid bark, 15% coco coir. pH 5.5–7.0. Keep the tuberous base slightly above the soil line to prevent rot. Repot in spring when roots emerge from drainage holes, one size up.
Feeding
▾
Balanced liquid fertilizer at half strength every 4 weeks in spring and summer. Apply to moist soil. Flush soil every 3 months to prevent salt build-up. Stop feeding in winter.
Yellow Leaves
▾
Usually overwatering — let the top half of soil dry and ensure good drainage. One leaf yellowing as a new one opens is normal. Widespread yellowing with soggy soil means root rot — unpot, trim black roots, repot in fresh mix.
Drooping Leaves
▾
Check soil first — if dry, water immediately. If moist, check for cold drafts or root rot. Newly repotted plants droop for 1–2 weeks; resolves on its own.
Brown Crispy Leaf Edges
▾
Low humidity or tap water mineral build-up. Boost humidity, switch to filtered water, and flush the soil with plain water. Keep away from AC vents. Existing brown edges are permanent — trim neatly.
Leaves Losing Deep Lobing
▾
Young leaves are naturally less lobed — deep, dramatic margins develop as the plant matures and in good light. Ensure consistent bright indirect light and warmth. New leaves become progressively more pronounced with each growth cycle.
Spider Mites or Mealybugs
▾
Inspect leaf undersides and petiole bases regularly. Wipe with a damp cloth then spray with diluted neem oil or insecticidal soap every 5–7 days for 3 weeks. High humidity deters spider mites.
