Water regularly after planting and throughout its first year of establishment, or in periods of drought. Although this plant is considered drought tolerant, its ideal soil is moist, rich, and well draining.
It may be cut back it it becomes too large, or falls over. It's suggested to cut back this grass in late winter, just prior to the formation of new year growth. Leave at least 2" of foliage when cutting back.
Propagation is best achieved via division in spring shortly after new growth resumes.
