I was given a white pine on a black pine graft. Fairly common practice, and I have worked it into a lovely windswept style over the last couple years. However, the black pine nabari and Rootstock is bulky and ugly compared to the white pine graft. It looks like maybe there was a hardcut to the side of the graft which has not healed the scar? May I turn the black pine root graft/Nabari into a deadwood feature? Or would that kill the white pine attached? Other suggestions?
