Prunus 'North Star' Cherry Tree

Asked June 30, 2018, 7:26 PM EDT

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?

It's OK to use the cherries that appear to be healthy. Based upon what we can see in the photos, we think some of the fruit has been damaged by a disease called brown rot. Measures can be taken to help prevent that next year. Learn more here:
