Prunus 'North Star' Cherry Tree
Good size tree. 10 years old. Looks alive but less than half of the tree is producing fruit. Other side has cherries that haven't ripened. Many have fallen off. Lots of pits hanging in places where nothing's been picked. Maybe bird squirrel traffic yet seems different than any other year. Picking healthy cherries now. Is it ok to use them? And what can I do for my tree?
