1、 Illumination

Purple backed taro has low demand for light. It can be maintained in a bright living room without direct exposure to the sun and astigmatism. If the purple backed taro is exposed to the sun in a place with strong light, it is easy to sunburn the leaves, and the edges of the sunburned leaves will turn yellow and scorched

2、 Temperature

The most suitable temperature for the growth of purple backed taro is 20-30 ℃, which is heat-resistant and slightly cold resistant. If it exceeds 35 ℃ in summer, we should find ways to cool it. For example, if we put it in a cool and ventilated environment and keep the temperature above 5 ℃ in winter, we can survive the winter safely

3、 Watering

Purple backed taro needs more water during its growth. When it is found that the soil surface is dry and white, it should be watered in time until water flows out from the bottom of the basin. At the end of autumn, with the temperature getting lower and lower, reduce the watering and open the watering interval

4、 Humidity

Purple backed taro likes humidity. Compared with soil humidity, the plant prefers a high humidity environment. Under the condition of good ventilation, frequently spray water on the plant leaves and around to humidify, so as to prevent the taro leaves from scorching and drying due to air drying

5、 Diseases and insect pests

In the case of high humidity and no ventilation, purple backed taro is prone to leaf spot and leaf blight, which can be controlled by Carbendazim and mancozeb. In the absence of ventilation, purple backed taro is also easy to provoke scale insects, which can be controlled by scale Bizhi
