From the information given, it appears the tree may have been in stress for several years. In an urban setting competition for space, water, sunlight and resources can set the stage for problems and these trees are still susceptible to the same insects and disease as fruiting cherries. Extreme temperatures may have killed buds both two years in a row adding to any environmental stress.
* Dead or diseased branches should be pruned out, if possible.
* Water deeply during periods of drought.
* Early spring is the optimum time to fertilize these trees, Compost is an excellent slow fertilizer.
* A soil test would help you with nutrients and any pH problems.
* Be careful when applying pesticides for the lawn.
Good luck and please let me know if I can help you further.
