i planted some koala food trees in a circle ... they grew well ... and the idea was to create a little grove ... also that the roots of the trees would grow together and strengthen the lot
fruit trees in the same manner would be gorgeous

I was wondering what the problems are building an earthbag dome with burlap chaff bags instead of the polypropylene. If the building is quickly (a friend does this with an air pressure method) sealed by hemp/lime crete wouldn't that stop the bags from deteriorating and compromising structural integrity? What is the window/door to wall ratio for a classic dome?
