would not, however, recommend planting shrubs entirely in replacement soil. As the roots grow, they may rebel when they reach the native soil and the plant can effectively become potbound even though it is in the ground. Also, some plants deal with clay soil better than others, so plant choice is equally important for success. My first suggestion is to look to what is native in your area. Finally, you cannot beat the expertise of a good local nursery, and you have two terrific ones near you: The Phantom Gardener and Grandiflora up in Red Hook. I shopped at both when I lived in Hillsdale, and recommend them highly.
