Carnation is indigenous to temperate regions and prefers a temperature range of 68 to 95 °F (20 to 35 ℃). During colder seasonal changes, ensure to adjust its environment accordingly to mimic its native temperate climate.
Carnation 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.
