Answer: Ornamental grasses may be cut down in either fall or spring. If cut in the fall, however, the seed heads will be removed and thus one of their ornamental features will be lost.
In general, the grasses do quite well in containers although they may outgrow their pots in a season. Some of them, such as true pampas grass and the purple fountain grass, are not hardy here so must be grown in containers so that they can be moved into a heated area during the winter.
