Cares should be pruned in the winter to cut back the DEAD growth. The NEW growth emerges in the spring. if you did not prune it in the winter, just give it a "hair cut" Grasses are alot like us...with split ends. If it looks bad just cut it out!

I treat them like ornamental grasses - cut them down to the ground in late winter/early spring before new growth starts to emerge.

Thanks. Glad it's not a big deal.
