Tree pruning question 2
Hello, this is the second of my three tree questions. In this photo, there is another small serviceberry tree with a V branch connection. I cut one of these, it will turn the tree into almost a stick so I am hestitating. Second there is a diseased looking part of the trunk. THank you again!!
This is difficult because the sapling, unfortunately, is not in the best shape. It looks like the best thing you could do at this point would be to cut back the diseased branch on the right side. Then train the left-leaning branch (shown on the left in your first photo) to become your new leader. You will have to stake the branch to hold it up in place in a vertical position. Prune all lateral branches immediately below the new leader so that you have the one dominant top branch. There is information here on training a replacement leader.
Please refer to our fact sheet on pruning ornamental plants for information on how to make correct pruning cuts. http://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/TreesandShrubs/...
