One of my big concerns is that there is a large oak tree near the fence. I
don't want to disturb the roots of the oak by digging a trench.. now I am
wondering about building a planter above ground, and lining it with
perhaps
sheet metal..

Hmmm...a big planter...sit it on a few layers of hard plastic covered by
mulch. Hmmm. I wonder if Bamboo would stay inside a big decorative planter?
