Regional wintering strategies
Southern magnolia 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 -15°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.

Signs of Low and High Temperature in Southern magnolia

Symptoms of Low Temperature in Southern magnolia
Southern magnolia is cold-tolerant and thrives best when the temperature is above 15°C. During winter, it should be kept above -10°C. When the temperature falls below -15°C, 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 Southern magnolia
In spring, prune away any dead branches that have failed to produce new leaves.
Symptoms of High Temperature in Southern magnolia
During summer, Southern magnolia should be kept below 35°C. When the temperature exceeds 41°C, the leaves of the plant may become lighter in color, the tips may become dry and withered, and the plant becomes more susceptible to sunburn.
Solutions for High Temperature in Southern magnolia
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.
