Where Pit Planting, seeplanting detail for planting ring sizes and depths. Scarify the edges of planting pits to encourage root expansion.b.On project sites where topsoil is limited or nonexistent, a minimum depth of 6 (six) inches of sandy loam topsoilshould be tilled into the soil to a depth of 12 inches through all planting areas with compacted soils.c.For all newly planted areas, three cubic yards of composted organic matter per 1,000 square feet of landscape areashould be added to a depth of four inches to the top of the soil and Tilled in.d.Seeded areas shall be fine graded and rolled.
