Been promising Bill (Auburn) I would post a grown-up picture of this experiment (The ongoing saga of the prune on nanking cherry) and here’s a couple. The first should be a baby picture and the second and thirdshould be nine years later. To date we have enjoyed two plums from this tree!
Should not have photographed that with the apple behind the plum! The plum is the little one on the inside of the fence with the rocks at the base. The apple is much larger and outside the fence.
Don’t know- but the control (a root from the same clone that I transplanted at the same time) is on the same schedule, and the original tree was the same after I transplanted it 20-25 years ago.
