Spring is the time to trim your ornamental grasses.
Cut them back low to the ground as shown
It is still a little wet to divide the perennial grasses. As soon as the soil dries up a bit, it will be a good time to divide your clump(s) if you feel they are getting too large.
Here’s a step by step guide:
Select grass to transplant
Use spade to loosen soil around the entire root ball
Pop entire root ball out and place on level ground surface
With a sharp shovel or axe slice down through root ball (one plant can yield several new starts)
Dig a hole, cover transplant up to the top of root ball
