planting shrubs on a hillside
that is quite a challenge. I HAD to have these five globe arborvitae in the PERFECT spot on a hill. i didn't want them sticking out of the hill, but pointed upward as they should be. the back of the rootball was not problem. but, the front of the rootball was impossible to get covered with dirt, as i couldn't go any deeper with the hole or the back would have been way too low. i had to end up building two foot retaining walls in front of each to fill with soil.
how do you do this?
