Ornamental grasses add texture and movement to gardens, but knowing when to cut them back can enhance their health and appearance. Generally, ornamental grasses should be cut back in the spring, just before new growth begins. This timing allows the grasses to provide winter interest and habitat for wildlife, while also protecting the plant’s crown from harsh winter conditions.
