In fact, fertilizer high in nitrogen causes excess growth and weak stems so the usual neat habit is lost as the plants become floppy and unsightly. Grasses can be planted at any time during the growing season if the plants have been grown in containers. However, for the best performance the first year, it is better to plant in the spring or early summer. Transplanting and dividing should always be done in the early spring before new growth starts. 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.
