| If they were stored in protected nursery rows, one plant can shade the side of another. Occassionally, when removed from rows and put in yards, they can get a bit of sunburn to foliage that was previously shaded. Not sure if its your issue, but that is a common occurance. If you are only loosing a bit of foliage, don't worry too much if it's isolated and not spreading. Might be a bit small of a plant for the new International forum, but if you ever have questions for regular trees, check out the new forums at... www.treeworld.info Participants from several countries.
