Grow grass on red clay and slope
I bought this house last year and it had no grass in the back yard. All the top soil had washed away. I put in a gravel barrier to keep water from damaging my slab again. I put in st Augustine sod. I could not do the whole yard at one time so put them across the yard. I have lots of runners. Some are rooting and some are not. The ones not rooting are growing way above the ground. Any suggestions would be greatly appreciated.
