Dying birch tree?
Hello. We have a birch tree in our front island. For about 2 years now portions of the tree leaves are yellow, not green. We are also losing a large amount of little branches/twigs whenever it rains or is windy. The tree is about 15 years old. It was always healthy in appearance until about 2 years ago. It looks quite sickly now. The tree was trimmed rather significantly right before these visual signs appeared. Can you please advise what could be wrong and possible fix? Or who can we call/hire to evaluate and treat? Thanks so much for your help.

Your tree may be stressed from the severe pruning or it could be lack of moisture if the landscaping around it keeps it from getting adequate moisture. It could be suffering from chlorisis which is due to lack of iron. You could send in a soil sample to have your ph tested. You could also have a certified arborist come and take a look at your tree and determine what the problem is.
