Wrapping Trees For Winter Protection
Young, thin barked trees need protection from animals and weather, especially during winter. Tree wraps are a great way to keep them safe in the cold and protect the trunk from getting scalded by the sun.
Once the leaves fall off newly planted trees in the autumn, it leaves the trunk fully exposed to the sun. On sunny winter days, the sun’s rays will heat the trunk to high temperatures. Then, when the sun sets, the trunk will rapidly cool down. This will cause the bark to crack and damage the tree.
Trees should be wrapped for at least their first two winters, until their bark develops texture. Sensitive trees such as maple, linden, mountain ash, honeylocust, apple, crabapple, cherry and plum will benefit from protection for their first five winters.
Steps for wrapping trees:
- At the end of November, wrap young trees. Wrap should be removed in early spring (mid-April) to let the trunk expand and prevent insect infestation.
- Use a light-colored crepe-paper type wrap. Note: using plastic, dark colored materials or burlap can result in tree damage.
- Start wrapping at the bottom of the tree, overlapping by 1/3 until you reach the first branch. Tape the wrap to prevent it from slipping at the top of the tree.
- Unwrap the tree after the last frost in spring.
- Once the bark of the tree has hardened and become furrowed, it is not necessary to wrap trees.
