If there is no water change for a long time, the water quality in the water cultured white crane taro will be polluted, causing bacteria to grow in it, which may lead to blackening. You can cut off the blackened roots and leaves, clean the container, air dry the tap water and replace it in the container, and then continue to put it in for maintenance. Then pay attention to the frequency of water change. When the temperature is high, the water can be changed every 5-10 days. When the weather turns cool, the water can be changed every 15-20 days to ensure a clean water environment.
It can't stand the cold climate, especially the water raised white taro. When the temperature in winter is lower than 5 ℃, the plant will not grow normally, and will suffer from freezing damage, which will cause the water raised white taro to turn black. Need to adjust the temperature in time, turn to indoor maintenance in time in winter, it is better to keep the temperature above 10 ℃.
If too much water is added to raise the water level of the white taro, it will lead to too much water entering into the rhizome, which may lead to rot and blackening. To take out the plant, trim the blackened part properly, and then add water again for curing.
