Any lawn pro's with some advice?

on golf courses, greens are aeriated with generally one of three ways. the plug is removed and fertilized, the plugs are drug till they somewhat fill the holes, then sand applied ( unlike the lawn, the green in mostly a sand mixture). or it will be done with solid pike. there even is a machine that shoots a high presuure column of water that makes holes about the size of a pencil!

remember if you seed into a plug hole, it will generally be too deep for the seedling to emerge, so pay attention to that.

yes quality of sod will vary by soil type, water it gets, shade,..... but with correct pH, ferlizer, eliminating weeds, compaction, reseeding or overseeding, anyone can have a pretty nice lawn. like anything, just takes work and $$$ !!?? LOL
