My lawn is 8 months old so apart from a decent scalp and perhaps an initial level in one area which dropped a fair it I think I will be in the same boat. I really want to level the lot but I just don't think it's the best idea yet. Also the spot which has dropped will take more than a couple of instalments of sand to get it to the same level as the rest.

On a side note, this 30 degree and sunny day is fantastic. Last week I brought it down to almost scalping and it didn't look great after that. After a mow today I'm amazed at how little browning there is. I just wish some of this sunny weather was sticking around...
