Colorful taro is a tropical plant. It will grow well in the environment above 20 ℃. Born like sunshine, if the light is not enough, the colorful spots on the leaves will also become dark, and the leaves are too long and weak. Therefore, do not put it in a fixed position during normal maintenance, and move it to ensure more than 3 hours of light every day.
The most suitable temperature for its growth is between 25 ℃ and 30 ℃, and the lowest temperature is no less than 20 ℃. In winter, the temperature should be controlled at about 15 ℃, otherwise the leaves will turn yellow and the plants will wither. When the temperature is 22 ℃, the tuber will sprout new leaves. Therefore, the temperature in winter should be controlled between 15 ℃ and 20 ℃, so as to avoid the influence of too high temperature on dormancy.
The color leaf taro likes to be wet. It needs a lot of water in spring and summer to keep the pot soil moist, but avoid ponding. During the growth period of color leaf taro, fertilizer was applied once a week, and nitrogen, phosphorus and potassium were used together, mainly nitrogen.
The soil of color leaf taro should be loose, fertile and well drained. Since it's necessary to change pots like this, in fact, it's easier to change pots with colorful taros compared with other plants, because the colorful taros are dormant in winter and need to be replanted in spring, with half of the new soil replaced and the tubers buried a little deeper.
Diseases and insect pests are rare, so it is necessary to protect tubers. Tubers are prone to dry rot during storage. Once found, they should be sprayed with multi fungicides in time. During the growth period, leaf spot disease is easy to occur. Prevention is the main way. Fungicides should be sprayed every month to protect the healthy growth of plants.
April to August is the peak season for the growth of colorful taro, at this time to ensure adequate nutrients. After September, the leaves will gradually wither. At this time, the watering should be reduced and the fertilization should be stopped so that the tubers can safely survive the winter in the soil. Wait until the next spring flowers continue to grow.
