(1) Taro loves water. Taro has very strict requirements on water conditions, which is related to its growth habits and origin. Both calla and alocasia prefer moist natural environmental conditions.

During the seedling stage, the temperature is low and the growth is slow. You should hoe more frequently to increase the ground temperature and keep the soil moist. Strong growth in the middle and later stages requires adequate water supply. If the climate is dry and the temperature is high, more watering is needed. Since the soil is raised into ridges, watering can be done from the ridge furrow. Each watering should be 6-10 cm away from the top of the ridge. Always keep the soil moist, and then water when the water in the furrow is almost dry. During the high temperature season in summer, water in the morning or evening. When the temperature drops after autumn, water at noon to avoid damaging the roots. Pay attention to preventing waterlogging during the rainy season.

After the calla taro is successfully transplanted, the water can be drained and sun-dried to increase the ground temperature and promote its growth. When fertilizing and cultivating the soil in the future, the water can be drained to facilitate operation. From now on, the water in the calla taro should always be kept at 5-7 cm. When the temperature is high in summer, the water in the border should be kept at about 15 cm, and the water should be constantly changed to cool down. After the beginning of autumn, the weather turns cooler and the water depth should be maintained at 5-7 cm. Before harvesting, the water should be drained and sun-dried to promote the transfer of nutrients from the leaves to the bulbs and increase the yield for harvesting.

(2) Taro likes fertilizer. Taro has a long growth period, requires a lot of fertilizer, and has strong fertility tolerance. In addition to applying sufficient base fertilizer, it also needs to be topdressed multiple times. The growth in the seedling stage is slow and requires little fertilizer. It mainly relies on the nutrients stored in the taro seeds themselves for growth. Later, the plant growth accelerates and the amount of fertilizer required gradually increases, combined with weeding, soil cultivation, and watering at the same time. Generally, the soil is cultivated 3-4 times and top-dressing 3-4 times, and the amount of top-dressing is gradually increased. In the early stage, nitrogen fertilizer is mainly used to promote the growth of the above-ground parts, form a certain leaf area, and lay a good foundation for the bulb formation period. During the vigorous growth period, the soil has formed into ridges, and long-acting fertilizers such as decomposed livestock and poultry manure or cake fertilizer can be applied topically, along with phosphorus and potassium fertilizers to promote bulb enlargement and starch accumulation. Fertilizer and water should be controlled in the late growth period, especially nitrogen fertilizer should not be too much to prevent the aboveground growth from being uncoordinated with the underground growth, delaying maturity and reducing yield.
