Sun scald damage occurs during the winter months. Trees that have direct southern exposure, are highly susceptible to tree bark splitting and sun scald damage. Tree bark damage occurs during warm days when the sun heats the bark on the southern or south-eastern side of the tree. During the night the tree's bark cools. This repetitive heating and cooling, expands and contracts the tree's bark. If this expansion and contraction of the tree's bark continues over and over again it will cause the bark to split, exposing the unprotected inner layer of the tree.
Wrapping a tree with winter tree wrap paper protects the bark by maintaining a more constant temperature. The wrap absorbs the head of the sun, thereby reducing the expansion and contraction of the tree bark.
This apple tree in Boulder Colorado has suffered extreme bark splitting from direct southern exposure and temperature fluctuations.

This ash tree is suffering from severe sun scald. Ash trees are extremely susceptible to sun scald damage.
Start at the bottom of the tree and move upaward. This will create a shingling effect and the water will flow off the tree wrap instead of getting stuck inside the wrap.
Wrap the tree until you reach chest level or the first branch, whichever comes first.
Secure the wrap at the top and the bottom of the tree with grafting tape or duct tape.

* Minimum trip charge of $45 is required. If we are already at the property doing a different service like aeration or synergy there is no minimum charge.
The best time to wrap a tree to protect it from winter sun scald is during the months of October and November.
You should wait to remove the winter tree wrap from your tree until March 1st, but no later than April 15th
Sun Scald is the repeated freezing and thawing of bark following warmer temperatures in the winter season, resulting in permanent visible damage to bark. In the northern hemisphere, it is also called southwest injury because the bark of the tree tends to have the most damage on the southwest side of the trunk.
Winter tree wrap is a very effective tool for protecting the tree's bark from winter sun scald.
