A number of years ago, I finally had to cut (after several attempts at pruning out) my only plum tree down because of black knot. It persists around the property mostly on what I believe to be wild cherry trees and some chokecherry bushes. I want to grow plums though so any tips?
Would love to see this documentary. So much inspiring stuff going on there at Wheaton Labs. Chapters would be excellent , and also available in Canada as someone else mentioned.
