We have a honey locust tree that is aprox 20 yrs old and has not blossomed (no leaves) and this is the middle of July. We had our tree service out to inspect it, and it shows no signs of disease, poisoning, draught, or over watering. There is a lot of healthy plants around the tree, and we have 2 other of the same trees in the yard that are doing great and are about the same age. We have our tree service check our trees every year and there has never been a problem. They said the tree is alive as there is green bark under the bark when they peeled it back. Any suggestions?
