In some situations, purchasing topsoil is essential to create a successful landscape. In others, the purchased soil may be little or no better than soil already on site. Before making the decision to purchase new topsoil, determine whether the soil will be any better than material already on the site. If possible, have both soils tested. Compare the test results with these guidelines.
