Tree planting on an existing slope within a plant pit featuring angled sides and a width equal to two times the root ball. The root ball rests on undisturbed soil and is surrounded by amended backfill. A water retention berm is formed downslope, and mulch is held back three inches from the base of the trunk. A two-to-one transition slope blends the excavated pit into the existing grade.
