I was to dig out some grass on my front yard and plant shrubs trees etc. I would need about 3 or 4 yards of soil trucked in. Across the street from me they have just excavated to build a new house. There is a huge heap of dirt. Hardpan dug up that I'm sure isn't good planting soil. Rather than truck in new soil does it make any sense to move wheelbarrows of that dirt over to my yard and mix in fertilizer?
