3. Shade. Creating a refuge from the hot sun is important. Trees, shrubs, structures such as pergolas and gazebos and oversized market umbrellas are options. Besides offering escape from the heat, they often create a focal point for the space. When selecting trees, choose nonmessy varieties that won’t drop in your pool.
