Elijah blue is a blue festuca. I divide mine in spring. Dig them up and pull apart and pot up in good compost. This keeps their foliage looking good and rejuvenated the plant. And you will have more plamts in early summer to plant out. Or simply gently combyour fingers through the plant to remove dead stuff.
The brown one sounds like a sedge ....I cut mine back in spring almost to the ground. It grows quickly. Again, you can pull this plant apart and pot up but in this case I usually pull apart in half and replant in the ground.
