I usally put my screened dirt up in the middle of the summer, i spread a 4x8 piece of plywood on saw horses and dry it out. Sometimes i agree that the dirt dont match the dirt there, i then sift some duff or dirt from that area over the pattern lightly. It seems to work ok for me. I like to carry in dirt instead of walking around the site area. I use the carry in dirt mostly for bedding and then use the hole dirt for the top covering, Hope this gives you some answers.
