Health of Norway maple

Asked June 28, 2019, 2:49 PM EDT

We have a Norway maple (~45-years-old) in our front yard that's never been pruned or cut-back. One tree company estimator said it should not be pruned-back until the winter when it's dormant due to its ill health, further stress may kill it. Another estimator never mentioned any perceived health issues. It has some dead limbs and minor bark loss with interior decay (picture), but rather extensive leaf growth. Should we hold off on pruning it now? Thank you, Dallas Hoover.

Hi. Thank you for your question. To make a better decision on the health of the tree, could you attach a photo with all of the tree in the photo so we can see the tree canopy and the foliage?

You can prune right now. See the following pruning chart. The best time to prune, when you should not prune, and when it doesn't matter. If you have broken or dead limbs, you should remove them, they will attract insects and disease.
