I went out to look at someone yard the other day who had just recently (last fall) had the landscape completed. The back yard was seeded and the front sodded. The sod wasn;t laid very well with overlaps and such (or maybe it was shifting from rains slightly I dont know. Anyways The sod was really thatchy and could really use an aeration immediately and then a dethatching either this coming fall or maybe next spring. This didn't look like healthy sod to me, because of the amount of dead material in there. So my question is how soon after a lawn has been sodded would you guys aerate? I am worried the roller for the aerator is going to just roll up some of the sod. What about dethatching should I wait until the sod is well established 1 full year or more????? It really looks bad and they just want the lawn to look in better shape. My thoughts would be to aerate as soon as possible either early this spring or before the summer stress kicks in, and then dethatch the sod in the fall or possibly the spring. Any input?
