1、 Watering

In winter, the cultivation of cactus needs less watering, and the soil can not be too wet, because it has a certain drought resistance. Watering too much is not conducive to its root respiration, and it is prone to rotten roots. If you are in a heated room, you can water normally. If the temperature is lower than 3 ℃, you should keep the soil dry

2、 Proper ventilation

In order to prevent the plants from being frostbitten, most people will move the cactus indoors, and most of the rooms are very hot and dry, so it is necessary to open the window properly at noon. Only by allowing the plant to breathe fresh air can it survive the winter smoothly and reduce the chance of being invaded by diseases and pests

3、 More sunshine

The sunshine in winter is very weak. The location of cactus maintenance should have bright light. It is best to place it on the balcony facing south. It can not only meet its demand for light, but also improve the temperature of the breeding environment to some extent

4、 Temperature adjustment

If the temperature is too low during the winter, the plant will be frozen, so the temperature in winter must be kept above 5 ℃. If the temperature is lower than this, use plastic bags or paper boxes to cover the plants for heat preservation
