Wait until the late winter or early spring just before the Feesey Ribbon Grass starts to turn green and resume growth.
Put on garden gloves and gather all the dead grass blades that are above the soil. Gather up any that are lying flat on the ground as well as those that are still standing vertically.
Trace the dead stems back to between 3 and 5 inches above the ground. Cut the stems off at this location using hand pruners.
Gather up all the dead ribbon grass stems and place them in a compost bin or in the trashcan.
