Create a 2-4 inch blanket of inorganic (gravel) or organic (wood chips) mulch over the soil surface and around plants to conserve water, keep the soil cool, suppress weeds, reduce compaction, and slowly make nitrogen and other nutrients available.

Water evaporates quickly in the high daytime heat of August. Cover the pool when not in use to minimize evaporation. Add water lilies in fish ponds or water gardens to add brilliant color, minimize water loss, and prevent algae growth.
