Two maples recovering

These two famous maples (Acer palmatum and A. burgerianum) were at BMW headquarters all April. When they came back to the garden they got a serious sun burn as expected. Thereafter they looked shabby. I did partial defoliation, cut out lots of small dead branches. Now they start to shine again. The big one got lots of guy wires again. Even after 50 years of training this tree is not finished.
