My Bermuda grass keeps declining in the sides of my yard but is growing great in the center of the front & back. The same pattern of growth is occurring to all of my neighbors as well.
I live in a new construction in central Texas that is six months old. Neighboring houses were built slightly before ours. All houses have sprinkler systems which operate. During construction, our ground was graded and a layer of topsoil & manure was laid before squares of Bermuda.
For example, the house nextdoor was built before ours and still vacant. The builder has the sprinkler active and maintains the yard. The same pattern of death on the side yards is occurring.
