General pruning Acer species 
The Maples normally do not require regular pruning apart from damaged, diseased or dead wood removal and this should be carried out from autumn to winter. Pruning in late winter or spring may result in bleeding of the sap and should be avoided. Remove reverted branches in variegated trees and clean up split bark with a sharp knife and allow natural healing.
