Mine is oblong, possibly 8m x 4m but has evidently been, in the past, a very different shape. The previous owners grassed in old garden beds but a) the grass is a different variety and b) inevitably, the 'new' bits are sunken, in places a good 3 inches. Not a good look on such a relatively small area of grass! At worst, I'd say one 1/3 of the lawn is sunken, line straight across it!
Should I:
-Start from scratch, dig it up and re-seed or turf?
-Attempt to take out the ridges and fill the divots/troughs by strategically removing lines of turf?
-'Fill' the dips with topsoil straight onto the existing turf and seed that?
-Any other ideas?
