I have been asked to prune a plum tree that is too high. The lady
could not reach much of the fruit last year. I have had advice that I
could reduce it's height and start trying to re-train it, but there is
a risk of silver leaf finishing it off. I suspect it is quite an old
tree. It is growing against a south facing wall and must be about 20
feet at it's highest point. What are my options and your opinions?
Thanks, Johnny
