If money is no object, then double Milo will work for you. I see you live in Texas. It's a big state, but most of it is limestone soil. You might want to get a soil test at Logan Labs in Ohio. Post the results here and morpheuspa will read it for you and recommend a chemical tune up. In this case chemicals are necessary because they might recommend, for example, boron. Well there's no organic source of boron, so you have to use chemicals. Same with the chemical salts. Those have to be balanced for your organic program to really take off. Morph can do that for you. Just get the $25 test at Logan Labs and post your results here. Once you get the soil chemistry tuned up your organics should work better.

Water deep and infrequent. Deep means 1 full inch all at one time. Time how long it takes your sprinklers to fill several cat food or tuna cans in the yard. That will always be your time. Infrequent means to water once every month when the temps are below 70. Once every 3 weeks with temps in the 70s, once every other week with temps in the 80s, once every week with temps in the 90s, and once every 5 days with temps above 100. Start doing this now before it gets any warmer. This watering cycling will also minimize your weed problems.

Mulch mow at your mower's lowest setting 2x to 3x per week depending on how fast the grass is growing.

Fertilize heavily monthly. Bermuda can use all the fertilizer it gets.
