I have a waterfall lace leaf maple for over 12 years- been growing beautifully- then we moved and had it transplanted to new house- last year did ok but i think too much sun plus we wanted to move it again to another place- sooooooooo in the new place it now lives, now only half of the tree is blooming / has leaves on it- the non blooming branches appear to be in good health (all dead twigs removed) but no visible new growth on tree on HALF OF THE TREE ???
