Newly bought succulents must be repotted, or you will regret it when it is too late

Many friends who love buying cultivated succulents will buy lots of them at flower shops. When they see a beautiful one, they cannot resist taking it home. So, for the succulents we bring home, should we change the potting soil? Should we keep them in the original pot and soil, or replace everything?
Actually, I think that for succulents bought at flower shops, you should look at what kind of pot and soil are used, whether the soil has good air permeability, and whether it is nutrient soil or yellow clay soil. If it is a relatively expensive succulent, the pot and soil certainly will not be too bad, so it is fine whether you repot or not. But if it is grown in a simple pot, it is best to replace everything.
The soil mix for succulents bought from flower markets is relatively uniform. Over time, it easily becomes compacted. It is only good for propagation and cultivation, but not for succulent growth. It is best to replace it. Otherwise, the succulent will grow more and more listless, and by the time you regret it, it will be too late.
So how should we repot them?
First, carefully remove the succulent from the pot, being careful not to damage the leaves and main roots. Remove the excess potting soil. Soil close to the roots can be gently brushed off with a small brush. Do not pull or tug with force.
Place the succulent roots in water and gently sway them to wash off impurities on the root surface. Do not sway or rinse forcefully. Minimize damage to the roots as much as possible.
Clean up all dead roots, rotten roots and overly long old roots. Do not be reluctant to prune old roots. Old roots are no longer strong at absorbing water and nutrients. Only by cutting off part of them can the new roots that emerge make the succulent grow more vigorously.
After pruning the roots, soak them in carbendazim for five to ten minutes, then place them in a cool, ventilated place to dry. Once the water on the roots is completely dry and the roots are slightly dry, they can be potted.
Carefully plant the dried succulent in new potting soil and press the soil firm. At this time, do not water immediately. It is enough for the potting soil to be slightly moist. After about more than a week, the succulent will be able to grow new roots, and then you can water and care for it normally.
Note that during this more than one week of acclimatization, it must not be placed in direct sunlight. Just put it in a place with scattered light and good ventilation. If the potting soil is too dry, appropriately spray a little water mist on the surface. Be sure to control your hands and do not water.
