Question
My front lawn was landscaped with MidIron about 10 months ago (I assumed it was BobSod or Bullseye Bermuda - Used at the Bank One Ball Park in Phoenix).  The lawn sloped from east to west and water collected in the lower area.  I leveled the low area with the rest of the lawn by adding up to 4" of topsoil.  I installed BobSod and a thin layer of additional topsoil where the sod meets the existing lawn.

My lawn is now level.  However, I now have discoloration.  
The BobSod is a stunningly beautiful blue-green while the MidIron is sort of an emerald green.  Will the colors ever match?  What should I do?  I've considered scalping the lawn as close as possible and simply overseeding with Princess 77.  However, I'm not sure if this would make matters worse.  Thanks, so much, for all replies.

Hi Robert
First of all we need to know that no two grasses have same physiological character like colors or blade type.
So I can't say they can mix ever. But with age, grasses start getting more greener. This character might help you.Your overseeding will help you to diffuse their charaters.
