When should I cut back my ornamental grasses?

Question:

When should I cut back my ornamental grasses?

Answer:

Many ornamental grasses provide color, sound, and movement to the winter landscape.  Because of these winter features, cut back ornamental grasses in April in Iowa.  Cut back the grasses to within 2 to 4 inches of the ground with hand shears, lopping shears, or hedge trimmers.
