Grasses are tolerant of a wide variety of soils and pH. Like most ornamental plants, however, the better the soil the better the performance. Organic matter is more important than fertilizer. After planting, grasses can be mulched with up to 3 inches of mulch. Once established, grasses don't require extra water, even in times of severe drought. If water is available, however, they will perform better with additional water in times of drought.
Grasses come with various heights, flower types, blooming times and foliage characteristics.
Some have great winter interest. Some have variegated foliage or reddish foliage, either all summer or in the fall. Some make good cut flowers, either fresh or dried. Grasses serve several purposes in the garden. Others are good for screening.
