Grasses for the Southwest
Grasses for the Southwest. Most Grasses are easy to take care of. They are not susceptible to insects and rarely need to be fertilized. Most will go dormant during the winter seasons. You can cut them down low to the ground, and they will vigorously grow back during spring.
