Carex comans 'Bronze' pruning?
Has anyone else noticed how little information is available on Carex? I hope Darke's new book addresses this issue.
Anyway, I started 4 clumps of C. comans 'Bronze' from seed last year. 3 were planted in the ground, and one was wintered over in a 1-gallon pot, buried in the top of the compost bin:
You can just see in the photo, the line of demarcation between the reddish-bronze color of the blades on the lower 2/3's, compared to the dry looking tan of the ends. It shows up a little better in this photo:
Darke speaks only to Carex in general. He says evergreen or semi-evergreen species are "best cut back on occasional years, to remove old or winter-dessicated foliage."
Greenlee says, of C. comans specifically; "When cutting back, leave 3-4" above the crown, as plants dislike a close shearing."
Leaving 3-4" above the crown will eliminate the tan dry-looking ends of the foliage, but my question is whether or not those trimmed blades will continue to grow, with their squared-off ends, or will they be overtaken by new foliage?
I'm starting several more plants this year, so I can afford to experiment. I'm thinking about cutting back the one potted plant, and leaving the 3 in-ground plants alone this year.
Any experience trimming Carex comans, in any color?
