We planted 5 Dragon Lady hollies on the east facing side of our lawn. They are open to DE. wind with no protection. Although they were mulched heavier than we normally do, they should drain properly as they sit on the top of a slightly elevated area of our property. They were transferred and planted from Wye Nursery in MD. the same day they were planted in our lawn, Millsboro, DE. mid- August in hot heat! They did not seem stressed at all last year and they made it through the winter with no problems. I sprayed Neem Oil on them last fall also bc we saw tons of flies munching on something on the tops of most of the trees. The wet spring brought a small amount of leaf drop with some yellowing leaves on 4/5. I fed them all Holly Tone at that time in early spring and 4/5 have seen new growth and little to no droppage since that time. 1 tree continued to have leaf droppage with bare branches this spring and summer. I trimmed the tree of some dead branches on the top and in one area at the base. Now, just in the last 3 days, almost every leaf has fallen off of the 1 tree, June 23-25, 2018. I don’t see any insects. The only thing different about this tree is that we had a suet cake in it all winter.Enclosed pictures.
