Tree wound #747563

Asked May 02, 2021, 8:12 PM EDT

This wound is on a maple tree and the result of a heavy pruning maybe 12 or so years ago. My question is “Would it benefit the tree to fill the wound with something now and if so what would I use. There’s a pen in the pic for size reference. It’s about a foot across. Thank You for your help! Mike

No treatment is recommended for the old pruning wound. Adding fillers or pruning paint can interfere with the healing process. Here is our page on proper pruning cuts and removing large branches https://extension.umd.edu/resource/pruning-trees
