What is tree wrap and why is it used?

Tree wrap is usually reserved for thin-barked trees, exposed trees, or trees in danger of rodent and mammal feeding. Consult an arborist to determine if trunk wrap is needed. Tree wrap should only be used when necessary. If you do use trunk wrap, use one made of new, synthetic materials. They generally work better and are designed to avoid girdling the trunk. Always remove tree wraps after the specified time period to avoid damaging the trunk.
