The back property line had anywhere from 4-8 feet think of mixed growth, including an invasive bamboo-like species, and a red trumpet vine that kept invading our oak tree.  Luckily, our neighbors on that side agreed with us that it all had to be taken out, to start from scratch, with a fence and some nice hedges.
