Maple Tree Disease

Asked September 1, 2016, 4:50 PM EDT

Hello and thank you for this wonderful service. The maple tree -- a street tree -- leafs out nicely every year, but early in the season, the leaves on many branches turn brown, crisp, and die back. About six years ago we opened up the tree well so it would have lots of room for roots. I'm not sure what else to do. We'd like to try and save the tree. Any advice?

We really cannot make a diagnosis based on your photos. There may be several reasons for branch dieback such as drought stress, poor soil drainage, girdling roots, changes in soil grade, etc. Look at our publication on these types of problems http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG86%20Common%20Abio...
All you can do is keep the tree watered during dry periods, make sure mulch is no thicker than several inches and away from the base of the trunk, and prune dead wood. At this point, we recommend that you contact several certified arborists for a site visit regarding the health of your tree and the best way to proceed. http://www.treesaregood.org/
