Although,... I think my Northstar cherry tree has died. It's three years old and I've never had any previous trouble with it. Due to the freeze last year, this is the first year I've had cherries, though not too many. It had lots of blossoms, but I had a real shortage of bees earlier this spring.
But after we had an extra 5 inches of rain in June (that's a lot for Nebraska, though we didn't have flooding or anything), the leaves on the Northstar steadily turned yellow and dropped off. There's not a leaf on it now. It's in a flat area, not a depression or anything, and none of my other fruit trees had any problem (most have needed extra water since then, but there's been no irrigation anywhere near the cherry).
But there are no signs of borers or any other problem, so I imagine it must have been the rainy June. I'm pretty new at all this, though.
