If you don't do this step during a succulent's dormant period, it will go into complete dormancy

Succulents all go dormant, some in winter, some in summer. The leaves of a succulent become dull and lusterless, all the leaves on the plant look the same, the whole plant changes color - these are all signs that it is about to go dormant. There are also cases of withering and leaf drop; some succulents drop all their leaves as soon as they go dormant, their stems wither, and the plant's growth comes to a standstill - these are all signs of dormancy

When a succulent is in its dormant period, you must water it sparingly or not at all. If you absolutely have to water it, you can spray a mist of water around the plant, with just enough water to moisten the surface of the potting soil. A dormant succulent must not be placed in a stuffy, hot place - be sure to keep the air circulating. If the water on a succulent does not evaporate for a long time, the succulent's roots will rot from too much water

For succulents that go dormant in winter, the temperature must not be too low - just keep the temperature above zero degrees. For succulents that go dormant in summer, they must not be exposed to the sun; place them in a well-ventilated spot. If the indoor temperature exceeds 30 degrees, you can fan the succulent - an air conditioner or a fan will both do. When a succulent is dormant, you must take good care of it, otherwise it really will go into eternal sleep
