This tree was originally Methley. When I moved it from Vancouver to Battle Ground, I grafted on a Shiro Plum from the Vancouver yard too. Over the years, I added a Beauty Plum and a purple leaf plum for pollenation.
My Asian plums have a very low spreading, umbrella shape with long willowy branches. Most seem to droop quite low, giving deer a nice salad bar, plus making it difficult to mow.
I've never done a lot to shape and train this tree. Today I pruned back the lowest branches, shortened the long willowy branches, removed too-low, deer-tempting shoots and spurs, removed some crossing branches and cleared some of the center.
I left some newer branches longer, to tie down and train in the future.
No "Before" shot this time. I forgot.
