About this detail

Trees are planted in a shallow pit dug to three times the ball diameter on undisturbed soil, bearing the same relation to finish grade as in the container. The pit sides are roughened for moisture and root penetration while the top third of the burlap and wire basket are removed if balled and burlapped. A customized planting mix of four parts approved topsoil, one part soil-aid or peat moss, and slow release fertilizer fills the pit. Two wood stakes measuring two by two by twenty-four inches are driven a minimum of twelve inches into undisturbed soil at the edge of the rootball and tied with number ten wire through three-quarter inch rubber hose. A four-inch drain pipe slopes toward a swale or other trees, sitting beneath a crushed stone drainage layer. A twenty-four inch diameter circle is cut in the sod around the trunk for a water basin, and tree wrap and protection sleeve are installed.
