Answer: Ornamental grasses are sometimes slow to respond to favorable weather, but once they do, they make up for lost time. If you're seeing new green growth, the roots are healthy and as soon as the soil and air temperatures suit them, they'll put out lots and lots of new growth. Be a little more patient, and fertilize them lightly with either a 20-20-20 or a little lawn fertilizer. Best wishes with your garden!
