Bigroot geranium is naturally accustomed to a climate ranging from 41 to 95°F (5 to 35°C). It thrives in temperatures that resemble its original temperate habitat. It's most vigorous in spring and fall when the temperatures are moderate. A seasonal adjustment of its location may help to meet its temperature preferences.
Bigroot geranium has strong cold resistance, so special frost protection measures are usually not necessary during winter. However, if the winter temperatures are expected to drop below {Limit_growth_temperature}, it is still important to provide cold protection. This can be achieved by covering the plant with materials such as soil or straw. Before the first freeze in autumn, it is recommended to water the plant abundantly, ensuring the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.
