Paul,

The best procedure is to aeriate using a plug type aeriator, then to
dethatch immediately afterward , this will chop up the plugs for faster
dispersal.

Spring and fall is the best time to do this

I just dethatched my lawn yesterday and want to core aerate as soon as
possible. I was once told that I should wait several weeks after the
dethatching before aerating to avoid shocking the lawn. Yesterday I was
told that I could do both in the same day. Basically, I'm wondering if I
could core aerate next weekend. Also, can you "over-aerate" a lawn?

Thanks
