I will be removing around 8'' of mulch and other debris where some trees were removed and stumps were ground. I will be sodding with bermuda or centipede. How much top soil should I add in this area? The soil is mostly clay. Would you recommend using a good quality soil or fill dirt with good soil tilled in? Also, how would I go about sodding over exposed roots? The roots are around 1'' above ground. Should I just cover them with soil, and if so how deep? Another property has been eroded quite a bit and there are many crape myrtle roots on the surface. My customer wants this area sodded. I'm trying to keep my material costs down, as there is already many hours of prep work and installation time budgeted for this project (18 pallets) Any suggestions and previous experience would be appreciated.
