So i have this guy who called me the other day asking for me to give him a quote to plant about .3 acres of wildflower in his lawn. I have never done this before so I have been looking into it. Have any of you ever done this before? Should I remove all turf that is there or would rototilling it be enough?... I know that you dont want grass/weeds to start growing where the wildflowers are. He was also telling me that he thinks that what he is looking for is to have the area slicerseeded with the wildflower. Is this the right thing to do? Also he told me he bought the seed out of a catalog last year, do you think that it is too old? Sorry for the long post, thank you for your help!!
