I’m about to receive some wild plum (Prunus americana) trees which I ordered last fall. I’ve read that they like to thicket and grow well that way, or they can be grown as a single tree.
A thicket would be less work and take up less space. However, separate trees would be easier to pick and I’m guessing that I would also get more fruit. For fruit production alone, which growing culture would be best?
I would train it open center, like a peach tree. You will get good light and airflow. I would prune the scaffold to as high as you can reach with loppers or hand pruners. I don’t like to climb more than two steps to harvest my fruit.
A thicket might increase pest and disease pressure.
