Do you “roll lawns?

No. Many people complain of bumpy lawns, but it is the earthworms (which indicate a good soil) that usually cause the bumps. Rolling the lawn is just not the solution. It doesn’t really work. In the Spring, knocking down the crowns with a rake can help. A heavy core aeration may also do the trick. Topdressing with soil may be another option to smooth out uneven turf.
