In winter, the cultivation of cactus needs less water, and the soil should not be too wet, because it has a certain ability of drought resistance. Too much water is not conducive to its root respiration, but also prone to rotten roots. If there is a room with heating, it can be watered normally. If the temperature is lower than 3 ℃, it is necessary to keep the soil dry.
In order to avoid frostbite, most people will move the cactus to the indoor to raise, and most of the indoor are very hot and dry, so it is necessary to open the window properly at noon. Only if the plant can breathe fresh air, can it survive the winter smoothly and reduce the chance of being attacked by diseases and insect pests.
In winter, the sun is very weak. The place where the cactus is maintained should have bright light. It is best to place it on the south facing balcony for maintenance. It can not only meet its demand for light, but also improve the temperature of the breeding environment to some extent.
If the temperature is too low during the winter, the plants will be frozen, so the temperature in winter must be kept above 5 ℃. If it is lower than this temperature, it is necessary to use plastic bags or paper boxes to cover the plants for heat preservation.
