Fall planting generally has proved marginally successful. Most grasses can benefit from mulching and many from cutting back, usually just before new growth begins in the spring. Use hedge shears and wear gloves to prevent cuts from the razor-sharp edges of some species. A number of perennial grasses form root masses that may require a pruning or chain saw to divide and transplant. It generally is a fairly easy matter to grow annual types from seed.

In late summer, tan-yellow seed heads form on stiff stems. The upright seed heads measure 2 to 3 inches wide and 6 to 10 inches long.
