Potted Wisteria is common in indoor plants. The advantage of potting is that it is convenient to move, so if Wisteria is allowed to spend the winter indoors, it is necessary to move the pot to a cool place and keep the room temperature of Wisteria not too high. Because Wisteria needs to be fully dormant in winter, too high temperature will lead to early awakening of wisteria, consumption of nutrients, unable to store more "energy", thus affecting the quality and density of flowers in the next year.
If Wisteria is planted in the South and the outdoor temperature is rarely below zero, place the wisteria in the corner facing the sun, but the leeward. If possible, you can bury the whole flowerpot in the way, and wrap the branches with airtight plastic cloth to prevent wind.
If Wisteria is planted in the north, the best way to preserve it is to move the outdoor Wisteria to a room without heating, or to a room with low temperature such as a balcony facing north. On the one hand, to prevent the outdoor temperature is too low, frostbite wisteria, on the other hand, to prevent the north winter heating overheating, so that hibernation Wisteria wake up.
If you don't have the conditions to move into the room in the north, you can also imitate the south, bury the pot in the soil, keep the temperature of the flower pot, and then spread the plastic film on the ground, cover with straw, soil and other insulation. The branches also need to be wrapped with straw, plastic film, etc. to keep the temperature. Generally speaking, the temperature of Wisteria in winter should be between 5 ℃ and - 5 ℃.
