About the only thing that will keep seeded bermuda from taking over is too much shade. Shade comes in many forms. Of course buildings, fences, and trees give shade, but so do weeds and even some other grasses.

Bermuda can take high doses of a high nitrogen fertilizer every month during the growing season. It should be mowed low and watered deeply and infrequently. Here's what that means.

Watering: Deep and infrequent is the mantra for watering. This is for all turf grass all over the place. Deep means 1 inch all at one time. Put some cat food or tuna cans around the yard, and time how long it takes your sprinkler(s) to fill all the cans. Memorize that time. That will be the time you water from now on. My hose, sprinkler and water pressure takes 8 full hours to fill the cans. Your time will likely be less. I like gentle watering. As for watering frequency, that depends on the daytime air temperature. With temps in the 90s, deep water once per week. With temps in the 80s, deep water once every 2 weeks. With temps in the 70s, deep water once every 3 weeks. With temps below 70, deep water once a month. Note that you have to keep up with quickly changing temps in the spring and fall. This deep and infrequent schedule works in Phoenix and in Vermont, so it should work for you. The reason for deep and infrequent is to grow deeper, more drought resistant roots and to allow the soil to dry completely at the surface for several days before watering again. If it rains, reset your calendar to account for the rainfall.

This watering schedule is more important than any other factor. If you water too frequently the grass will not look as good. If you are in far east Texas with lots of humidity and rain, you may never have to water it yourself.

Thank you ! Great info . Here's a question for you . What if the tuna cans get a inch of water but the soil still remains hard ? I remember last year I did a test one time and ran sprinklers for 20 min each zone . About 10 min after completion I tried to stick a screwdriver in the ground and it went in maybe a inch or 2. But that was 20 minutes . I understand that with that time I should be getting about 6 inches deep of water. Does my soil need something added to it ? Thanks
