I recently moved into a house in Houston. The people before me probably never watered or did lawn maintenance for the past decade. I'd say about 1/4 of the lawn is st Augustine, 1/3 is Bermuda, and the rest is either dirt or weeds.
I put some weed and feed (Scotts plus S or something) that was suppose to kill the weeds and Bermuda grass and feed St. Augustine, but it didn't seem to do anything. I may not have spread enough weed and feed, should I do it again?
How can I promote the Augustine to grow? Am I fighting a losing battle and I should dig up the lawn and lay sod?
