The healthier trees are now showing approx. 6 inches of growth in the top 3-4 shoots that we left on the stems. All other shoots were stripped off when approx. 1" long, although I did snap off a couple this week, and it was easier when approx. 2" long, so next year I'll leave them a little longer before stripping the lower shoots.
A few plants have something eating the leaves, not sure what it is yet. more investigating to do. Looks to be an insect of some kind as there are holes developing in the middle of the leaves.
