How to care for Giant Taro
Alocasia macrorrhizos · Araceae
One of the largest-leaved plants you can grow indoors, with glossy, upright, arrow-shaped leaves that can exceed a meter in a big pot. It is a fast, hungry, thirsty grower given warmth and light. Far more forgiving than the jewel alocasias, but it needs real space. Water roughly every 5 days while it's growing (about every 10 in winter), give it bright, indirect light, kept above 59°F (15°C) — average room humidity suits it.
Care at a glance
Water deeply when the top few centimeters dry — big leaves transpire heavily and it wilts dramatically when thirsty.
Give it your brightest spot; it tolerates some direct morning sun once acclimated.
Half-strength balanced fertilizer every three weeks — large fast growers feed heavily.
Mistakes that kill this plant
- Leaving it cold and wet in winter, which rots the trunk-like rhizome.
- Starving it of light and food, then blaming the plant for shrinking leaves.
- Letting spider mites establish across those big leaves unchecked.
Seasonal tips
- Growth slows sharply in winter — cut watering back and stop feeding.
- Wipe the huge leaves monthly so they can photosynthesize efficiently.
- Repot in spring before the growth surge; it can double in size over a summer.
