Plant care:

Best growth occurs in full sun with well drained soils.This grass is very tolerant of dry, infertile soil. This is a cool season grass, so its most active growth occurs in spring. In warm climates the plant will go dormant in summer and resume growth in the cooler temperatures of autumn. In cooler climates it will continue to grow into autumn. Since this grass remains semi-evergreen through winter, it should not be cut back until early spring, before new growth begins. At that time, it can be cut down to the ground if needed or simply trimmed to remove winter damage.
