1、 Warm keeping measures

The temperature in early autumn is not very low, and it is still in its bearing range. In late autumn, the temperature drops relatively fast, so it is necessary to control the temperature. If the measures are not in place, it is difficult for it to survive the winter safely. After the temperature drops, it should be moved to an indoor place with appropriate temperature for maintenance. Heating has begun in late autumn in the north. Don't put it directly on the ground during maintenance. Ground heating will affect its growth. It is cold in late autumn in Jiangsu and Zhejiang. Indoor maintenance should not be placed in ventilated places such as doors and windows to avoid cold air frostbite

2、 Control temperature

Whether it is maintained in the South or in the north, it is necessary to control the temperature of its growth environment at about 20 ℃. If it is lower than 15 ℃, it will enter dormancy, and if it is higher than 25 ℃, it will grow in advance. This is detrimental to its growth, which is equal to overdrawing nutrients in advance, and the flowering effect of the next year will be affected

3、 Scientific watering

After autumn, the climate is relatively dry and the water evaporation is relatively fast. At this time, it is necessary to appropriately increase the amount of watering and spray water on the branches and leaves. In October or so, the temperature drops rapidly. It is necessary to reduce the amount of watering to stimulate its branches to reduce moisture, so as to achieve the full development of tissues and prepare for lower than severe cold

4、 Pruning

In order to avoid excessive dispersion of nutrients, it is necessary to conduct an autumn shear after autumn, and cut off the dry, damaged and fast-growing branches to make the nutrients evenly distributed
