1、 Move indoors

The potted landscape of Vitex negundo should enter the house as much as possible during the winter. The outdoor temperature in general areas is very low. If it is not moved to the house, it may be frostbitten. If you have floor heating at home, you need to put it high. If you put it directly on the ground, the heat emitted by the heating will cause dryness

2、 Pay attention to ventilation

Although it is relatively warm to put it indoors, it can't be without ventilation. If the plants are stuffy in the house all day, it will increase the probability of plant diseases and insect pests. Therefore, it is necessary to open more windows at noon on sunny days in winter, and the indoor air should be well circulated

3、 Proper watering

In cold winter, we must control the amount of water. Don't water it all winter, and don't pour too much water. Basically, it's OK to pour it thoroughly every time. In addition, we should pay special attention to the water temperature. Some flower friends will pour warm hot water on the plant in order to avoid freezing. This is a wrong practice. Water at normal temperature can be used

4、 Outdoor insulation

If the bonsai cannot enter the house, it needs to be covered with a large plastic bag, which is like a heat preservation shed, and it will not be easily damaged by freezing
