Fruitnut, usually for me the leaves are just delayed with stone fruits, and eventually pop out. I know there needs to be enough leaves to provide chlorophyll action to sweeten up the fruits, but there should still be time. It is my apples that will show these weird long nodes in the middle of the branches where there ARE no leaf nodes, for those apples that need higher chill hours. But, they still produce, too. I can actually see the difference between my two Fuji cultivars - one is just “Fuji” and the other is “Red Fuji”. Red Fuji requires more chill hours, has wider leaf nodes and is now just blooming. I already have some set on that tree, but more on the regular Fuji. Both also tend to alternate bear for me, so not sure if that is also related to lack of chill hours, or a quality of that cultivar.
