The room temperature should be kept at 7-10 ℃, and the temperature should not be lower than 5 ℃. If it is below 0 ℃, it will be frozen to death. During the growth period, except for the need for shade in hot summer, it should be placed in a sunny place.   2.

When it is hot in midsummer, Crassula Arborescens is in a semi dormant state. It is OK not to water it for many days.
