If the grasses are not cut back, spring growth will be delayed and the plants will be unattractive late into the growing season. Manual trimming with a string or electric hedge trimmer works well for small areas. Large areas can be burned, if burning is permitted and closely supervised. Do not cut or burn in the fall, because winter injury may result, and the winter beauty of the plants will be lost.
