How do you pot succulents and help them settle in? A planting tutorial teaches you the correct method

Actually, newly purchased succulents all need their roots trimmed once, especially succulents bought online, whose root systems will definitely be damaged after a long journey, so before we repot the succulents, we must trim the roots beforehand; only then can the succulents settle into their pots better and the death rate be reduced.
When we first receive the succulents, we should first clean off the soil attached to the root system, then check the condition of damage and disease in the succulent's root system. If it is not too serious, we can appropriately wash the roots clean with a carbendazim solution, and then we can prune away diseased roots, old roots and overly long lateral roots; the lateral roots can be kept to between 1-2 cm.
After trimming the roots of a succulent, you cannot pot it and grow it right away, because at this point the roots will have wounds. If you pot it directly, the wounds are very likely to become infected with fungi or bacteria (a succulent infected with fungi is very hard to root, and the plant body is also very prone to black rot later on). The correct approach: place the root-trimmed succulent in a ventilated, shady spot (for two to three days), and once the wounds have healed you can pot it and grow it.
A newly potted succulent cannot receive light right away, because overly strong light together with spring wind can easily cause sunburn on the succulent's leaves. So in the early stage, we had best first keep the succulent in a shady, ventilated place for a period of time before considering the issue of light exposure, and then slowly extend the lighting time.
If after growing it for a period of time the leaves at the base of the succulent show signs of withering, then that means the succulent has completely settled into its pot!
