Some grass species require considerably more water than others! This is in turn leads to more water costs and expenses. You’ll want to consider the climate of your local area. For example, the Bermuda Grass is more adapted to dry/hot climates and is extremely drought resistant. It however, is not good for shady areas. On the other hand, Kentucky Blue Grass is more of a cool season grass. It has fair drought resistance and requires more water. Experiment with grass species and see how it fits your area, this can save you a lot of money!
