Hackberries are useless.
Mulberries drop their berries, which in turn rot, and the OP would make excuses for the "mulch", not to mention all the birds that would crap all over everything,
And Maples drop leaves which I am sure would have to be raked up by the neighbors.
And tearing up the grass and planting weeds? Really?
Hell, MY property value went down reading this bouncy.
