How do you do it and in what types of soil? Ive seen TONS of jobs where literally almost half the top of the burlap root ball is exposed above ground, and just mulched around. I have a customer complaining because a few of his trees died, and he states specifically in an email that its because i buried the root ball "below grade", below what grade? The top of the root ball is at the very top, level with the dirt, yes the whole thing is buried. Anyone run into excess water buildup in gardens and decide to leave each root ball half sunk into the ground?
