Well one of my customers spoke with me the other day about his bermuda receding more and more. He has two large trees in the front yard that are blocking out the sun during most of the year. I also know that the roots of these trees go right into where the grass should be. I think it's a combination of the roots sucking up all the water the grass would regularly have and the shading of the grass. He would like me to do something about this. Part of the area has washed away and it continues to wash every time it rains. He mentioned maybe getting fill dirt and filling this area in some but I'm worried the fill dirt is just going to wash out just like the rest of the soil has. I'm thinking there should be some type of retaining wall or something to hold the fill dirt back. Here are some pictures. I think that I might just bring out the island more since the grass isn't going to grow there anyways. I know I could trim back the trees a good bit, heck I think just taking some of the lower large limbs would make a diffrence. I'm just looking for some more ideas for this yard and how to solve this problem.
