Tree Wrap

Fall is here and it’s time to start thinking about protecting our young  trees from the impending winter cold. Tree wrap is designed to keep your babies safe from the elements and keep them looking their best after the thaw. Sunscald can occur on the side of young deciduous tree trunks.  A typical Colorado winter day may be sunny and up to 60 degrees Fahrenheit, causing the living layer under the bark to come out of dormancy and become active.  If temperatures drop below freezing it kills active cells and conductive tissue. Young, thin-barked deciduous trees, such as honey locusts, fruit trees, ashes, oaks, maples, lindens and willows are at highest risk. Commercial tree wraps made of crepe paper insulate bark and are an effective way to prevent sunscald. In late October or early November, wrap trunks upward from the base of the tree to a point just above the lowest branches. Overlap about 33 percent with each turn.  Secure the wrap with tape, but be careful not to attach the tape to the tree bark. Be sure to remove tree wrap and tape the following April to avoid girdling and possible insect damage. More tips on winter tree care are available from Colorado State University.
