Lawns and rolling

Thanks very much,
Doug says that if the ground is really bumpy on a new lawn, the builder didn't level it before they laid the sod. You can roll but it's only going to increase compaction on the conpacted parts and not do much for the softer ones.
My guess is that you're going to want to allow the lawn to settle a bit and then fill in low areas. At least that would be what I'd be doing. Filling and allowing the grass to work it it's magic at penetrating the underlying compacted soils.
And of course using a lot of compost and compost tea to bring the soil alive.
Good luck.
