Q: I recently had some bermuda sod installed around our pool. It looks pretty good and is starting to green up. The crew was adamant that it did not need to be rolled right away. Instead, they said roll it when it is wet from a heavy rain.

A: Rolling has nothing to do with making the lawn flat. The purpose of rolling new sod is to get the roots in tight contact with the soil underneath. Leveling the area should be taken care of before laying the sod by raking smooth and rolling it once to disclose low spots, which can be filled with soil.
