Well after removing all branching last autumn and leaving a bare trunk, I was happy to see some new buds earlier this spring but unfortunately not enough appeared. Some at the apex and some clustered around an old wound too low down. One has popped in a suitable location for a bottom branch so I wired it and am letting it thicken. The others at the apex have been repeatedly clipped and the new emerging buds nipped to promote short internodal length. I’m feeding vigorously to try and get these new buds in the middle of the trunk. I may have to try more threadgrafts at some point. Large old wounds were also reopened to try and encourage more callousing which has been pretty poor over the last year.
