1、 Increase frost resistance

It is not frost resistant and needs external management of water and fertilizer before it can survive the winter safely. After autumn, we should stop using fertilizer, especially nitrogen-containing fertilizer. At the same time, reduce watering and keep the soil dry, which can make the branches and leaves more lush, so as to effectively enhance the frost resistance

2、 Proper temperature rise

The low temperature limit temperature of such plants is 0 ℃. When the growth environment is lower than 0 ℃, the growth state will be broken and the leaves will be frostbitten. Therefore, it should be moved indoors for maintenance before cooling in late autumn. Indoor maintenance should avoid being placed in the door and window to prevent cold wind from blowing it. The temperature fluctuation in winter should not be too large, which will affect its dormancy. It should be controlled at about 10-12 ℃, and the temperature should not exceed 145 ℃. If it exceeds 15 ℃, it will grow buds and consume nutrients

3、 Proper watering

In winter, it will be in a dormant state to prevent the soil from being too dry or too wet, and don't wait until the soil is completely dry before watering. Water should not be poured heavily, and the water in the soil should be balanced. It still needs photosynthesis in winter. If the leaves are covered with dust, it will affect the effect of metabolism. Water should be sprayed on the leaves every ten days to clean the leaves

4、 Don't leave the room too early

The temperature in early spring is relatively low. For it, it is still winter, so it is necessary to wait until the temperature is stable in spring and the climate warms up before leaving the room
