Overview
Taro is a tropical root crop that is the staple food for millions of people across the Pacific Islands, Southeast Asia, and parts of Africa. The starchy corm is boiled, steamed, or made into poi (Hawaiian) or laplap (Vanuatu). Taro leaves (called callaloo in the Caribbean) are also eaten as a nutritious vegetable. The crop grows well in waterlogged conditions where few other food plants can thrive, making it invaluable for wetland agriculture. In the Pacific Islands, taro has deep cultural significance and is central to feasting, trade, and identity. Taro leaf blight has caused devastating crop losses in the Pacific.

Cultivation Guide
Plant corm tops or suckers (huli) with 2-3 cm of corm attached
Space at 90 × 60 cm for dryland taro, 60 × 60 cm for paddy taro
Maintain 5-10 cm standing water for paddy taro throughout the growing season
Apply balanced NPK fertilizer — potassium is especially important for corm development
Remove infected leaves promptly to manage taro leaf blight
Harvest when lower leaves yellow and die back naturally — corm is mature
Companion Planting
Strategic companion planting reduces pest pressure, improves pollination, and can significantly increase yields.
