Young trees are especially susceptible to bark splitting and scalding, which can attract insects and cause disease or sap loss. To safeguard your trees from these threats, Jobe’s TreeWrap reflects heat and acts as a barrier to insects and rodents. This patented material insulates while allowing the free exchange of air and water. Simply wrap the base of your tree in overlapping spirals. TreeWrap will stretch as the tree grows providing long-lasting protection. The roll is 4 inches wide with 20 feet of material.
