I want green grass. not dead grass...

I got St Augustine grass plugs from my uncles yard about 5 yrs ago. This grass "runs" and will overtake any of the vertical growing type grass. My lawn looked like yours before the St Augustine took over. Now I have a yard that is fully covered, green, and it feels like you're walking on carpet. My neighbors like it so much they have gotten some plugs out of my yard when I built my shop. It's now in their yards taking over. Bermuda runs as well but I like the St Augustine better.
