In winter, even in a warm room, it is also necessary to ensure that the winter temperature of flowers is high and avoid freezing. But it is not that the higher the temperature is, the better. Most flowers will be in dormancy or semi dormancy state after entering winter. If the temperature is too high, there will be physiological activities, even buds sprouting, which will waste the accumulated energy, but it is not good for growth. Therefore, the temperature should not be higher than 20 ℃.
Secondly, the light intensity in winter is weakened. In addition to effective antifreeze, flowers should also be exposed to more sunlight to warm them. Receiving more than three hours of light every day is conducive to the growth of the next year.
In winter, flowers grow slowly, some of them will go into dormancy, and their ability to absorb nutrients is not strong.
If too much fertilizer is applied to flowers in winter, it will damage the root system, make it more chilly, and reduce the evaporation of water. If too much water is poured, the root system will not breathe well, and it is very easy to cause root disease or even rotten root death.
Therefore, the winter flowers need little water and fat, which can maintain life.
In winter, the climate is already dry. With the use of household air conditioning, the air humidity is reduced, thus affecting the growth of flowers. In winter, the air humidity of jasmine, Swiss cheese plant and cactus should be no less than 50%, while that of Chlorophytum, bamboo and Acorus calamus should be more than 60%. When the humidity is insufficient, the spray mist method can be used to solve the problem.
