Temperature Essentials for Red pine

Regional wintering strategies

Red pine 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 Red pine

Symptoms of Low Temperature in Red pine

Red pine is extremely cold-tolerant, but the winter temperature should be maintained above -35°C. If the temperature drops below this threshold, although there may not be any noticeable changes during winter, the branches may become brittle and dry during springtime, and no new shoots will emerge.

Solutions for Low Temperature in Red pine

In spring, prune away any dead branches that have failed to produce new leaves.

Symptoms of High Temperature in Red pine

Red pine is not tolerant to high temperatures. When the temperature exceeds 32°C, it may experience significant leaf drop, and in severe cases, the entire plant may wither and die.

Solutions for High Temperature in Red pine

Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
