Re: Leave plugs after aerating lawn?
I'm not so sure that there's a wrong answer to your question.
By raking them up, the lawn will look better.
If you leave them, the lawn looks like poop, but, aeration is to get air and moisture deeper into the root base of the grass. Leaving the plugs does add a little to the compaction, but not significantly. I would be more concerned with them creating bumps and lumps in the yard faster than normal.
