I have a Chinese elm tree that was in bad shape when we moved in a year and a half ago. The previous owner layer landscaping rock all around it and took the black plastic right up to the base of the tree with the irrigation line on top of the plastic. Brilliant...
I transplanted the tree a year ago to a more hospitable place. My problem is the owner before had no clue how to prune trees. He cut randomly and without a goal in mind. I pruned it back to two main branches. He had already lopped off the central lead. I have attached a picture of the tree.
Any suggestions about how I should prune this for optimum health so it will achieve height and a wide canopy somewhere down the line?
