First, kill off your Rye grass (winter), chop it back, and fertilize like the picture below. I highly recommend you hire a professional for this portion. I use Bim, he’s fair, honest, and trustworthy. Bim’s Lawn Service.
Once that process is complete, you should water your Bermuda grass (summer) once a day at 5AM for 20 minutes. Yes, thats every region for 20 minutes. This should go on for 10 days. After 10 days, switch to only 4 times a week at 20 minutes. Keep your sprinkler start time at 5AM. Bermuda grass should be fertilized 4 weeks after you start the process of growing it.
