Kentucky bluegrass should not have gone "dormant yellow brown". If it's
bahia and yellow-brown in the winter it's probably dormant. If it's
Kentucky bluegrass and yellow-brown it's probably dead.

You may be about 5 months too late to effect a solution. Take out a big
piece, roots and all, and take it to your extension service ASAP, preferably
along with a photo of your entire yard, but expect the worst. Then take your
sample and the extension service's comments to whoever installed the sod and
see what they'll do -- Regards --

Hello . I have one year old bluegrass sod. Sand and clay soil. We were not
advised to add top soil (I wish we had). Last October the lawn went
dormant yellow brown. This spring it looks bad slow growth.
I had it aerated and de-thached but there is still a lot of dead grass
present I am trying to rake it out.
I have applyed Scotts products to supply nitrogen, iron and stimulate root
growth, its get plenty of water..and no dice. There should be an inch or
two of growth by now ...slow growth slow to green.
I cant afford to replace $8000.00 of sod WHAT CAN I DO?
