1、 Soil

Cactus is not very strict with soil, but it must be loose and permeable. Its roots will release organic acids. If the soil itself is very sticky, plus its organic acids, it will harden the soil. After watering, the water is not easy to evaporate, which will cause rotten roots. Rotten leaf soil, river sand or peat and perlite can be used for planting in the proportion of 1:1

2、 Illumination

Cactus is relatively strong to light during the growth period, but there are also some special species. For example, cactus in tropical rain forest such as crab claw and false Epiphyllum do not have particularly high requirements for light, so it should be at the place where the light is scattered. If it is in summer, direct exposure to the sun will cause burns. It has a certain phenomenon of chasing light. If the indoor light can not meet the requirements, its growth point will face the source of light, and will become thin and thin

3、 Moisture

The water management of cactus should grasp a principle, which should be dry rather than wet. It is OK to dry and pour thoroughly

4、 Temperature

Cactus can grow normally when it is above 5 degrees. Individual varieties can be resistant to low temperature, but they are not resistant to low temperature for a long time. If it is below 0 degrees for a long time, freezing injury will also occur

5、 Precautions

In the dormancy period and low-temperature dormancy period, we must pay attention to water control, do not water, and do not water too much, otherwise decay will occur. Some of its bristles will hurt people during maintenance. If there are pets or children in the family, they should be protected to avoid unnecessary injury
