Help with Centipede problem
I live in central AL. My grass is centipede. I have lived here for a couple years and my front lawn seems to have a problem area. As you can see in the pics, it is pretty thin in this area. I can't get it to spread and fill in. It was like this last year. I am afraid it has been over fertilized and might be in decline. I only put down 18-0-18 last year one time. I don't know what the previous home owner did. I have not fertilized this year and don't think I'm going to put any N down. I did put down some Dr. Iron but apparently the type of iron isn't the best to use because it isn't readily available in the soil. I liked it because it said it wouldn't stain. I do have a soil test sent off and should get the results soon.
I water once a week and have used a tuna can to figure out how long it takes to fill it up. I know I probably can't get a lot of answers until the soil test comes in but was hoping this could be a starting point. I am thinking of just getting some centipede plugs and plug the area after I figure out if I need to amend the soil first. I have also started putting down a mixture of baby shampoo and molasses to help the soil.
Also, the shade is only there in the late afternoons and is from a small crape myrtle.
