I cut most of my grasses back hard in the early spring.
All of these:
Pennisetums (except Little Bunny and those like that because I have NEVER been able to get them to over winter).
Panicums
Eragrostis Purple Love Grass
Muhlenbergia Pink Muhly Grass(some years it does not over winter, I'm just on the cusp of its survival zone)
Calamagrostis (Karl and Overdam)
Korean Feather Reed Grass
I have Carex Evergold for the first time. I looks a little ratty but not too bad. I'm not going to cut it back. Maybe just trim out some bad spots
But I have Carex Frosted Curls and I give that monster a hair cut late summer and hard cut in early spring.
I have Juncus. I'm not sure if that is really a grass. I have the corkscrew version. I do NOT cut that back. Just a bit of trimming. But if I had the regular straight variety I think I would cut that back partially in spring (I cleaned my neighbors beds and she had some, I cut it back
)
I no longer have any Miscanthus. They were thugs in my gardens. But I did cut them back hard when I had them.
