got my first complete landscape install next week and had a couple questions- 1. The lot now is clay- bringing in topsoil and putting it about 2-3 inches in depth. Then applying starter fertilizer and then putting sod in. Does that sound like the correct technique? 2. For the landscaping portion, i'll be install the plantings into mostly clay. Will that do ok in that type of soil? I'm getting kinda nervous. Want to make sure i do it all right. thanks!
