I had a new lawn installed 4 weeks ago. the landscaper used 4 triaxles of birm (filler dirt) and 2 triaxles of topsoil for approx 8200 sq ft of lawn. he used a rye/fescue/kbg mix and the front has come in very good, the back is a bit spotty but I will address that next spring. I watched him go over the areas repeatedly with his bobcat and it was packed down when he finished. My problem is that every time it rains, which has not been much this fall, you literally can not walk on the lawn for 3-4 days after until it is dry. If you do, you sink about 4-6 inches. Now I know you will probably say to just stay off the lawn, which I have but the deer don't seem to care and now I have a ton of tracks that are 4 inches deep and I'm assuming that my only choice next spring is to fill in all the spots with addt'l topsoil. Long story short, will the soil eventually harden up? Any advice/help with this would be appreciated. Also, is there anything I can spray to keep the deer off my lawn? it's starting to look pretty pathetic in the front for a new lawn with all of the holes from the deer tracks.
