Temperature Essentials for Gray alder
Gray alder 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 -30°C, it is still important to provide cold protection. This can be achieved by wrapping the trunk and branches with materials such as non-woven fabric or cloth. 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.
