proper proportions for peat moss (tree planting)
i have been planting a lot of large green giant arborvitaes
5-7 ft. i dig a large enough hole to accommodate the root ball and back fill with a mix of about 25% peat moss and original soil. after the hole is filled i make a small trench around the perimeter of the root ball an put about one cup of bonemeal and cover it up.
i am never quite sure about the optimum proportion of peat moss? is my method ok or is there anything else i can do to give the tree the best possible start?
