First, I'd say you should wait a few days to a week before asking for feedback because it is difficult to tell if a lawn treatment has taken effect a day after it is applied. That said, after a couple weeks I see the healthy grass looking green and thick, but I see no improvement in the sparse sections of the lawn. I have centipede grass and St. Augustine grass for the most part. I have had an ongoing and seemingly fruitless discussion about needing the centipede grass treated for weeds. Centipede is NOT bahia, and it can benefit from weed and insect treatments. The right rear section of my yard looks terrible because no one will apply treatments to the Centipede grass. Also, I was told that atropine could be applied in the winter months to subdue "stink vine" but that was not done and now the vine is invading the front lawn at a rapid pace; driving out the St. Augustine grass. On balance, I have given your company more than a year to help improve the lawn but I don't see much change from what i believe is a fairly expensive service.
