My client's lawn is mostly weeds now. I'm afraid to kill the weeds and have nothing left but soil. Before hiring me, he never fertilized the Centipede sod. And now his lawn is at least 75% weeds. I gave him a few options like fertilize or just redo the sod. But what about over seeding? Can I put down Centipede seeds to eventually push out the weeds, use herbicides later? I'm thinking I can just aerate the lawn, put down seeds, and let the Centipede grass take over. Am I right?
