Our tree has little red leaves and grow pink flowers similar to cherry blossoms. It has started to die and we noticed black bubble like things 'growing' on it those branches were dying. We cut those branches off but now every branch has it. I love this little tree but I worry now it's to late and it needs cut down.
Allegheny County Pennsylvania
You can take a sample of the bark and foliage to your local Penn State Extension and have them identify it, or you can call a licensed arborist to have your tree examined at your home.
