Is it Carex comans 'Bronze' or one of the other bronze colored varieties?

If it's C. comans (which is New Zealand Hair (or Hairy) Sedge), it'll take light shade but does better in the sun. It can tolerate drought after it's established (2-3 years), but needs water until then.

The plant that died was definately the C. comans and that one was in a mostly shaded area. The other three are in a light shaded area, getting afternoon sun. Should I cut them back now? If so, just lightly? Fertilizer? I know a lot of grasses state "do not fertilize"

Thanks

I can't advise about pruning, unless you can tell me what Carex it is.

I can tell you it probably doesn't need ferts. Nothing more than a normal amount of organic material, like compost as a top dressing.

Kitty,
I have several species of Bronze coloured Carex that are doing well in a location similar to the one you describe, all the way through to full sun. Suprisingly, they don't like to be really dry - I would say they are content with the same care as most of your other perennials.
At this time of the year you should still see some 'healthy-looking', firmly attached leaf blades. Trim them back to 3 - 4 inches and cross your fingers. You certainly won't kill it by trimming.

Unfortunately I don't have any more info other than what came with the plants at the nursery I purchased them. Can you tell me what kind of grasses do well in really shaded areas if any. I did planta a variety called Dwarf Golden Sweet Flag which looks veryt healthy but has not had any growth that I can tell of. I'm good with the ferts now and I will try a little compost material.

Thanks

I think I will take your advice and try a little trimming back. I'm new to the grasses and just wish I had more space to put in more. I really like the Purple Fountain Grasses but although they say they are a perennial I haven't had any luck in seeing them come back. I think my area must be too cold.

Thanks

Here are a few grasses which work in part shade:

Carex muskingumensis
Luzula nivea
Luzula sylvatica
Sesleria caerulea
Most Calamagrostis will take part shade
Chasmanthium latifolium
Hakonechloa macra
