... and they tell you to keep off a newly laid lawn ...! I hired a roller and that was just about hopeless. I filled it with water - though I suspect it should have been sand. My only fear is that the lows in the lawn, being softer than the highs, are likely to get deeper with the pitter-patter of tiny feet zooming across it.
I think I've decided to wait a couple of months - say until September - and then slowly top-dress while there is some growing space between then and November. Does anyone know of a supplier of good topsoil ... or give me the ideal formula for this type of dressing so that I can go to a local supplier and ensure that I get the best stuff -- rather than graded builder's refuse??
