Temperature Essentials for Japanese ginger

Regional wintering strategies

Japanese ginger is highly cold-tolerant and does not require additional frost protection measures during winter. However, before the first freeze in autumn, it is recommended to water the plant generously to ensure the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.

Signs of Low and High Temperature in Japanese ginger

Symptoms of Low Temperature in Japanese ginger

Solutions for Low Temperature in Japanese ginger

In spring, remove any parts that have failed to sprout.

Symptoms of High Temperature in Japanese ginger
