1、 Soil

The soil with strong drainage capacity and air permeability should be used to raise cactus. Pay attention not to choose too fertile soil, otherwise it is easy to cause rotten roots

2、 Illumination

Cactus is native to tropical areas. It is a plant that likes light very much. If it lacks light for a long time, it will be very thin. Generally, it can be raised in a sunny place all year round, and there is no need to shade it even in summer

3、 Watering

Cactus is very dry, watering can not be very frequent, but it can't be watered, otherwise it will wrinkle and age in advance. Generally, more water can be poured in summer, and the water should be strictly controlled in winter

4、 Temperature

The optimum growth temperature of cactus is 20-30 ℃, which can not be lower than 5 ℃ in winter. In addition, in winter, we should pay attention not to make the temperature difference between day and night too large, otherwise it is likely to cause freezing injury

5、 Precautions

1. Change the basin in time. Generally speaking, the pots of adult cactus do not need to be changed every year, but once every 2-3 years, but the pots of young cactus need to be changed every year

2. Pay attention to the water quality. Cactus is not resistant to salt and alkali, so it's best to use well water or rainwater for watering. It can't use water with too high salt content, otherwise it will affect its normal growth
