Requirements for Growing Taro/Arbi


Growing taro in partial shade or filtered sunlight is ideal. Avoid keeping the plant in harsh sunlight for long durations.


Grow it in the well-drained and fertile soil, which is rich in organic matter. Soil should be slightly acidic to neutral with a pH level between 5.5 to 6.5. Avoid compacted and clay-rich soil.


Water frequently and deeply to always keep the soil moist. Adult plants are drought-resistant but don’t grow long in the lack of water.

Some taro cultivars grow in in flood-prone areas with running water or on the banks of waterways. Stagnant water sites are not suitable for them because the corms may rot more easily in these conditions.
