Wisteria is not hardy, but the temperature is too low in winter, so we should pay attention to temperature control first. In the evening, the temperature should be kept between 5-10 degrees. If it is too low, the plants will be frostbitten, which will affect the growth of the next year. But too high also can't, otherwise the plant will wake up ahead of time, will absorb nutrients, make it can't bloom normally when it comes to flowering
The light in winter is relatively mild, and it should be placed in a place with sufficient sun during maintenance. More sun exposure can not only improve the temperature, but also make it safer for winter. However, if it's windy, keep away from the tuyere when you see the light to avoid blowing.
In winter, plants will stop growing under low temperature. At this time, the consumption of nutrients is very little, so do not over frequently supplement water during maintenance. Watering can wait for the soil to dry and turn white, and do not water if it is not dry, so as to avoid frostbite. In addition, a fertilizer can be applied before winter, which can improve cold resistance and help winter. But do not apply fertilizer after winter, root system will not absorb but easy to bring fertilizer damage.
In addition to temperature control in winter, measures can also be taken to keep warm. Cover the plant with straw to prevent frostbite. If it's seedling stage, it's OK to cover the plastic film on the top of the plant. Pay attention to poke a few small openings to ventilate.
