wound care for a tree

Asked June 30, 2020, 2:18 PM EDT

Large section broke off of my maple tree. What do i put on the wound? I've heard of roofing tar? Or is better to not paint it with any kind of wound care?

Assuming the wound does not impact the trunk itself, you (or an arborist) should make a "clean" cut to allow the wood to seal properly and minimize the risk of infection or infestation. See "proper pruning cuts" and "removing larger branches" about halfway down this page: https://extension.umd.edu/hgic/topics/pruning-trees. If the break goes into the trunk and removed some bark, an arborist should evaluate the wound and see if anything can be done. If you need to find an arborist, you can use the second and third links on this page to search: https://extension.umd.edu/hgic/topics/how-do-you-decide-when-remove-tree

Do not paint or coat the wound with anything - this can actually worsen the chances of the tree "healing" properly.
