Yeah not a good sign. The tree seems to do that, as did my sweet cherry trees. Nadia was beautiful this year, covered in flowers, spurs all over the larger branches even. My White Gold cherry is the same way this year. It has hundreds of fruits, now to keep them! Spraying again tomorrow! I pruned the tree to net it properly. I need to spray now too. I should have taken a photo of Nadia, I did of White Gold though. Photo taken May 8th. Nadia looked better than this one, still pretty though. A little past full bloom, notice the leaves.
