Anyone have any idea what is wrong with my sycamore tree (picture attached)? It just doesn't seem to be leafing out this year and there are small dead leaves intermixed with the mature healthy ones. We had plenty of water this spring (maybe too much???) and I don't recall it getting zapped by a spring frost. Last year it did get zapped but the little leaves just died and were replaced by mature healthy ones that leafed the tree out by June.
