Haworthias grow best in a subtropical area with mild to warm winter days (14~25 °C) and cool to cold winter nights (preferably 4~10 ºC). When the temperature falls below 4 °C, plants may suffer from freezing injury. In summer Haworthias prefer warm to hot days (25~38 ºC) with mild to cool nights (14~20 ºC). They do not like high overnight temperatures above 24 ºC. This is because they collect carbon dioxide for photosynthesis at night, and this process can be inhibited by high temperatures.
