Karl Forester in winter
I'm new to grasses, so excuse me if this is a dumb question! What happens to Karl Forester in the winter? Does it hang around or die back? Are you supposed to cut it back like a perennial or let it remain? If so, what happens in the spring? Do you cut it back or watch the old grass mix with the new green? There's an area of my yard where I need something vertical (to block the view of trash cans) and I was thinking of planting a narrow evergreen. Now I'm wondering if some sort of vertical grass would work. It would be far more interesting visually, but I don't know if it would be practical. Thanks.
