We built a new house and had a landscaper deliver and level topsoil before hydroseeding. There were a number of large areas in the yard that were covered with bedding sand rather than topsoil (sand was used to cover the many rocks in the native soil/clay and also used to backfill the irrigation and septic field). The landscaper assured me that the grass would take on these sandy patches. But six months later, I can say I am not happy with the result.
The grass on top the sandy patches dries out very quickly and does not get as green as the surrounding grass. I have dug up a couple of these small (2 sq. ft.) dry spots and mixed in some peat soil under the grass roots, but this is a time consuming process. Moreover, I have some much larger patches.
My question: Can I topdress this problem away?
Thanks
