Plants should be divided, in spring, every few years, to maintain freshness. Foliage can be left standing all winter, however, it should be pruned early to mid-spring to make way for new growth.

Warm Season Grasses: These grasses are much slower starting in the spring. They do not push new growth until temperatures warm in early to midsummer. They flower later in the summer or fall with most blooms remaining into the winter. Most warm season grasses tolerate heat, humidity and drought; some even thrive in these conditions. Conversely, extra care should be taken when planting in early spring or late fall.
