1、 Winter curing method

1. Take the ball and save it: if there is no way to provide a warm growth environment for the big rock Tung in winter, it will enter a dormant state and stop growing. When the temperature is lower than 5 ℃, it is recommended to take it out of the pot, cut off the excess stems and leaves on the plant, and then put it in a cool and ventilated place to dry for a period of time. After that, wrap them in newspaper and store them in a low temperature and dry place. It can be replanted after the temperature rises in the coming year

2. Normal maintenance: in winter, if you can put the big rock Tung in a warm room and provide it with a growth environment above 5 ℃, you can also directly maintain it without taking the ball. During maintenance, pay attention to put it in a place with good lighting conditions and let it receive more sunlight. In addition, we should also pay attention to maintaining ventilation, and do not put it in the closed place for a long time, so as to avoid its poor growth

2、 Precautions

1. If you want to take the ball, you must be careful not to hurt the seed ball. Otherwise, even if it is planted again next year, the plant will grow badly

2. If it is to be maintained indoors, it should be noted that with the decrease of temperature, the frequency of watering and fertilization should be gradually reduced. If the temperature is lower than 10 ℃, fertilization can be suspended. After the temperature rises in the coming year, return to the normal watering and fertilization frequency
