Bad pruning

One of the easiest gardening no-nos to observe (just walk anywhere) is bad pruning.  This is a so-so bad example here.  The lowest whorl of branches was too low, and by the way, not pruning off the lowest branches of lawn trees is another easily observed no-no.  Here the branches 2-3" in diameter were just wacked off, sloppily cut off leaving a stub.  The tree may grow out and around such stubs, but this injury will remain internalized to the end of this tree's life.  The normal decay of such stubs may also lead to a hollow tree because this becomes an avenue to the heartwood of the tree.  This hurts so much to see.  If you look up tree pruning on the web & just try a little it will come out better than this.  However, this tree is in the lawn of a rental and this fairly demonstrates the attention, or more usually the lack there of, to landscaping around these buildings.
