Triangle plum is not cold resistant, and the temperature drops to six to eight degrees, so it needs to be transferred to the maintenance site. It can't live through the winter when it's exposed. It can live through the winter when it's placed in the outdoor sunny shelter and the double-layer plastic film shed with its back against the north wall. Or put it in a closed Nanyang platform, 40-80cm high in the windward and sunny place, it's safer to live through the winter, and it's better to cover the bag to keep warm.
When the temperature reaches 8 degrees, it enters the house in the south in the middle and late November, and in the north in the late October.
Before moving indoors, prune the bougainvillea, keep the main branches and some flowering branches, and reduce the consumption of nutrients.
In winter, the temperature is low and the water evaporation is slow, so the watering should be reduced and the basin soil should be kept dry. Stop fertilization to prevent the high temperature and vigorous nutrition growth and the weakening of cold tolerance.
In winter, it will enter a short dormancy period, and leaves will fall. After dormancy and leaves fall, do not water as much as possible. If the soil is too dry, a small amount of (warm) water can be poured into the basin.
In winter, when plants move indoors, aphids are very easy to occur before defoliation, and need to be controlled in time.
After moving to the room, place the plants in a well ventilated place with sufficient sunlight and proper temperature for maintenance. At ordinary times, open windows for ventilation to avoid sultry environment.
If the ambient temperature is low, it can be enveloped by bamboo and wood strips, and the barrel shaped plastic film can be directly purchased to cover it. The upper plastic film mouth is tied and fixed with a rope. Loosening the rope can facilitate watering and spraying water from the top of the triangle plum, which can play the function of moisture preservation, heat preservation and defoliation prevention. The smaller triangular plum basin is covered with plastic bags, which can keep moisture and heat and prevent falling leaves.
It's better to leave the room late. In late March, new buds sprout in the balcony with the temperature rising. Some flower buds have already differentiated in Qingming Festival. If they leave the room at this time, they can't bloom in May when they are frozen. Therefore, they should leave the room when the minimum temperature is stable at 12-15 degrees, and leave the room in April to May. After leaving the house, prune dead branches, useless branches and beautify the plant shape.
