Are you curious about how to repair St. Augustine grass? Basic steps you can take are relatively simple. You start by raking the area of your lawn that is suffering. By letting the rake go into the soil just a bit, it will help dislodge dead grass and loosen roots. Get rid of weeds, stones, and any other extraneous items (since they could interfere with the grass seed’s ability to form a connection with the soil). Then install plugs or lay sod.
