Cactus flowers mostly grow in the arid desert of North and South America. The arid soil environment is not conducive to plant growth. In order to survive, it can only change its structure, absorb water from the soil and reduce water consumption. Thus its stem becomes very thick, which can store a lot of water, and its leaves become needle shaped.
It is very drought resistant and can resist high temperature environment, but this does not mean that its growth does not need water, or because of reasonable watering, so it can grow more vigorously. It likes light and is afraid of acid soil. The pH value between 7-7.5 is the best, which is most conducive to growth. If it is cultivated at home, it should be placed on the balcony with good light, and the soil should be mixed with appropriate amount of sand.
During the maintenance, pay attention to frequent ventilation and give enough light time. But in summer, it is still necessary to shade to avoid strong sunlight and sunburn. If the plant is placed in the airtight place for a long time, it is easy to be infected with pests, and the leaves will turn yellow, which will affect the ornamental and growth. In addition, we should pay attention to the temperature, especially in winter, when the temperature is low, we should put it indoors and provide a temperature of more than 5 ℃.
