Cactus potting is best carried out in early spring, cutting and grafting is best carried out in April to May every year.
Cactus requires good drainage and air permeability of soil, and the best choice for cultivation is sandy soil.
Cactus is best cultured in a dry environment, it is afraid of water, but drought resistant. Therefore, potted cactus can be watered less. It's best to choose the water that has been dried for watering. Pay attention to water thoroughly when watering.
Cactus likes high temperature and dry growth environment, so it's better to keep the room temperature above 20 ℃ in the daytime in winter, and the temperature at night can be relatively low, but there should be no large temperature difference, and the temperature should be kept above 10 ℃, otherwise the low temperature will lead to rotten roots.
The cultivation of cactus requires sufficient sunshine, but it is better not to be exposed to strong sunlight in summer. Although cactus is resistant to drought, after all, there is a gap between the cultivation of cactus and the cactus in the desert. The cultivation should be properly shaded, and the illumination of light is conducive to the healthy growth of cactus.
