New Lawn - Wrong grass seed put down
I am purchasing a new home, so I contacted the builder and we came to an agreement that I would supply the grass seed in place of him using his "contractor mix". I put out the money and purchased the best seed possible. It is a tri mix of Kentucky Blues (70%) and (30%) Rye mix. It has 0.00% Fuscue and weedseed.
Well, the lawn was installed today and they put down the 'contractor mix' seed and left my bags of seed untouched. The area coverage is about 10,000 sq ft. The front of the lot has sod. I'm supposed to close on the house tomorrow and I have no idea what is possible for cleaning up the mess he made. I don't want to deal with tall fescue and junk grass. The seed was spread and then covered with straw. The seeded part of the lawn has not been watered.
Any suggestions on negotiating a fix to this problem would be appreciated. Thanks in advance.
