1、 Suitable temperature

Generally speaking, cactus is suitable for growing in a high temperature environment, preferably at 20 to 30 degrees. The early autumn can generally meet the requirements. However, the problem of dormancy due to low temperature needs to be considered in the late autumn. How high the temperature is to be maintained depends on the type. If it is terrestrial type, it is more suitable at 4 to 7 degrees. If it is epiphytic, the temperature needs to be higher, preferably at 10 to 13 degrees

2、 Sufficient light

Generally speaking, cactus prefer light, and strong light will not cause harm. Therefore, you can generally get more sun in autumn, and you don't need shade at noon. However, the species of cactus should be considered. If it is epiphytic, the semi shade condition is better

3、 Appropriate amount of fertilizer

Fertilization can be done every twenty days in autumn. Fertilization is suitable for sunny morning or evening. If the soil is very dry, you can drip some water before fertilizing. After fertilization, water the next day. The terrestrial type is best to use phosphorus fertilizer and potassium fertilizer, and the epiphytic type uses nitrogen fertilizer

4、 Proper moisture

It doesn't need much water in autumn. It can be watered after the soil is dry, and it should be watered thoroughly every time. The interval between two watering should not be too short

5、 Proper ventilation

If it is maintained indoors, pay attention to ventilation in autumn to provide it with fresh and good air
