Perennials and Grasses

2. Cut back and divide perennials as needed.

Prune flowering perennials to a height of 4–5 inches and ornamental grasses to 2–3 inches to allow new growth to shoot up. Where soil has thawed, dig up perennials, such as daylilies and hostas, to thin crowded beds; divide them, leaving at least three stems per clump, and transplant them to fill in sparse areas. Cut back winter-damaged rose canes to 1 inch below the blackened area. On climbers, keep younger green canes and remove older woody ones; neaten them up by bending the canes horizontally and tipping the buds downward. Use jute twine or gentle Velcro fasteners to hold the canes in place.
