Raw stone flowers are not cold-tolerant, and the temperature is low in winter. First of all, pay attention to temperature control. The minimum temperature should be kept above 10 degrees, and the warm environment can ensure that it will not be damaged by freezing. Let it bask in the sun more, and it can be placed on a well-lit windowsill. It is best to bask in the sun all day, and the light is enough to raise the temperature. In addition, the water consumption is relatively small at this time, so we must pay attention to water control to make the soil slightly dry.
