I just had an irrigation system installed and took it upon myself to patch the damage that was done by the pipe laying process. The good news is that the grass came in nice and fast. The bad news...it doesn't match.

My lawn is primarily turf type tall fescue. I made the mistake of buying the Pennington Contractor's Mix for my area (SW Ohio) without looking at the actual seed types that were included. The newly patched area using this seed produced grass that is a much lighter shade of green and is growing MUCH faster than the old lawn. Since using that bag I switched to using a tall fescue blend for the remainder of the lawn and it matches perfectly. But the areas that I patched with the contractors mix look terrible due to the higher grass height combined with the lighter color. I suppose there is nothing I can do but kill it off and re-seed, but before going down that path I thought it would be nice to get other opinions.

Any thoughts?
