Crassula can at a 6-12°C cool place (bedroom, stairwell) overwinter. In this case, water only on sunny days with adequate heat sparingly. An all-year culture on the window is very well tolerated. The plants have to be watered but cautious, even in winter. Caudex shape types come better with longer dry periods along than herbeacous species. From april to september succulent fertilizer 'Sukkulentendünger' is given as the description says.
