last year my tree broke a branch, this year only half of my tree it blooming. The other half is bare with brittle twigs. What should we do?

Hi, Sue. Best thing in case is to contact a local Certified Arborist to check it out. There could be many reasons for the twig failure, and it may or may not have anything to do with the broken branch.

Find a CA at International Society of Arboriculture and follow links to Find an Arborist.
