Wounded trunks

There are many types of wounds on trunks and most will heal on their own. The good news is, a tree has the amazing ability to seal off or compartmentalize most wounds. Still, when a tree trunk receives a wound, the injury becomes a pathway for disease, insects, and decay. This situation might be repeated many times during the life of an individual tree, so a long-term plan for caring is essential to the continued health of your trees. Consult LWTeecare as to best way forward

Tree trunk injury can happen naturally in a forest and the causal factors include storms, icing, , insects, and animals. Inappropriate logging and forest management practices cause damage that can eventually affect the entire tree stand.

The urban landscape can suffer unintentional trunk injuries from construction equipment, lawn mower dings, and improper limb pruning.

A tree can usually recover if no more than 25% of its trunk is damaged around its circumference. Because the underlying cambium tissue is what transport water and nutrients up from the roots to branches and leaves, a more serious trunk injury can kill the tree by effectively starving it. 

If damage to the trunk occurs, experts recommend cutting away the damaged portion of the bark tissue down to solid wood. Do not use tree paint or any other coating, but watch the wound carefully. Over time, the trunk wound should begin to close itself on its own, provided it has not been damaged too severely. If rot begins to set in, however, the prognosis for recovery is not good, and you may want to consider removal of the tree sooner rather than later. Consult LWTreecare for best way forward.
