Newly planted trees and thin-barked trees need protection from the Colorado winter. Just because our state has 300 days of sunshine, these days can take their toll during winter months as well as summer months. To provide your trees protection from the sometimes harsh Colorado winter, the team at Landscape Connection recommends the following care:
Apply Tree Wrap
For newly planted trees and also for thin-barked trees, tree wrap is necessary. Thin bark trees include linden, honey locust, willow, mountain ash, fruit trees, maples, and ashes.
Tree wrap helps prevent sunscald that often occurs on the south and west sides of young trees that have not yet formed their protective corky bark. The daytime sun warms the tree’s cambium layer, and the cells in the cambium then become damaged when the temperature drops at night. Tree wrap is an easily applied alternative in saving your new or thin skinned trees!
Type of Tree Wrap
There are a few types of tree wrap, and our team will work with you to find the perfect fit. Generally, tree wrap is light in color to reflect the light and cuts down on the heating process. We always recommend the use of tree wrap made from “crepe or crinkled paper” to insulate the trunk. This tree wrap is available at local garden centers, hardware stores, and big box stores, and keeps trunk temperatures cool even when faced with direct heat from the sun.
How to Apply Tree Wrap
You want to wrap the tree early into the winter so preferably in November, but the beginning of December works just fine! The important part is to get to your trees before the weather gets too extreme.
In wrapping your tree, start at the bottom of the trunk, overlapping the wrap as you wind it upward. Secure the end with a staple or small tack. Don’t use tape or twine, as it may girdle the tree.
Start wrapping at the base of the tree, overlapping one-third with each turn. This ensures the wrap will shed water (If you start at the top and start wrapping down the overlaps are facing upward, and moisture can get in between the successive layers of the wrap). Wrap up to just above the second branch. You’ll need to wrap the trees for their first two or three winters or if they have thin bark.
Removing Tree Wrap
Remove the wrap around Easter. It is imperative that the wrap is removed in the spring; if left on it can harbor insects or disease, and the material can injure the tree as it expands.
When Sunscald is not a Concern
Sunscald is less likely to be a problem for trees planted on the east or north sides of buildings because they are less likely to be in full sun than are trees planted on the western or southern exposures.
Sunscald isn’t a summer problem because leaves protect the tree trunk from the sun, the sun is higher in the sky, and freezing temperatures aren’t likely.
