sugar maple not leafing out
There may be several reasons for the branch dieback. You may be dealing with poor soil drainage, drought, girdling roots, mechanical damage to trunk, changes in soil grade, etc. Take a look at our publication for information on these types of problems http://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/TreesandShrubs/...
At this point we recommend that you contact a certified arborist for a site visit regarding the health of the tree and the best way to proceed. The tree is located next to the house and you need to check to make sure it is not a hazard. http://www.treesaregood.org/
