Stipa calamagrostis is a deciduous grass, the old foliage should be left over the Winter as this will protect the crown of the plant from inclement weather conditions and will still provide structure and interest, especially on frosty days. Cut them back close to the ground in February or March before the new foliage emerges. The cut stems and foliage is useful as a natural mulch or may be composted.
