It is best not to use grass. Grass will grow under swimming pools and up through the liner or up the wall between liner and pool, or up the inside of the uprights creating great habitat for bugs and wasps. Choose some type of rock landscape and it is best to use plastic under it because the water splashing out of the pool makes any vegetation grow very quickly. Plants should only be container type plants. They are easy to move when changing liners and they don't grow roots under the pool.
