1、 Control temperature

Wisteria is not cold resistant, and the temperature in winter is too low, so we should first pay attention to temperature control. The temperature in the evening should be maintained between 5-10 degrees. Too low will frostbite the plants and affect the growth of the next year. However, too high is not enough, otherwise the plant will wake up in advance and absorb nutrients, making it unable to bloom normally at the flowering stage

2、 Sufficient light

The light in winter is relatively mild. During maintenance, it should be placed in a place with sufficient sun. More exposure to the sun can not only improve the temperature, but also make it safer to spend the winter. However, it should be noted that if it is windy, stay away from the air outlet when seeing the light to avoid blowing injury

3、 Controlling water and stopping fertilizer

Plants will stop growing in low temperature environment in winter. At this time, few nutrients are consumed. Therefore, do not replenish water too often during maintenance. Water can be poured when the soil is dry and white. Do not pour it if it is not dry to avoid frostbite. In addition, fertilizer can be applied once before winter, which can improve cold resistance and help winter. But don't apply fertilizer after winter. The root system will not absorb it, but it is easy to bring fertilizer damage

4、 Warm keeping measures

In winter, in addition to temperature control, measures can also be taken to keep warm. Straw can be used to cover the plant to prevent frostbite. If it is in the seedling stage, it is also OK to cover the plant with plastic film. Pay attention to poke a few small openings for ventilation
