Troubleshooting
Giant Taro problems — and how to fix them
Giant Taro (Alocasia macrorrhizos) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Drooping or wilting
Most often underwatering in this thirsty bog plant, or sudden cold; keep the soil evenly moist and warm, and it usually perks back up.
Browning leaf edges
Low humidity or dry soil crisps the large leaf margins; raise humidity with a humidifier and maintain consistent moisture.
Spider mites
Dry air invites mites that stipple and bronze the leaves; raise humidity, wipe the foliage and treat with insecticidal soap or neem.
Rhizome rot
Cold, waterlogged soil rots the rhizome despite the plant's love of moisture; ensure the pot drains and ease off water in winter.
