pruning or cleaning up of carex secta?
I have a large clump of what I think is carex secta...about 4 feet tall and wide, and the plant is about 4 years old now. It's gotten very heavy with what looks like dead undergrowth. How do you recommend pruning or cleaning it up? I can reach under with gloves on and pull off the dead grass from the base, but there is substantially more dead grass above it that will not pull or comb out.
I know we're not supposed to shear or heavily cut carex or sedges...however on one New Zealand grass website they say eventually you have to give it a severe haircut to the ground to force new growth.
Before I do that, has anyone in here given that treatment to your carex plants? Did they survive? Is it worth it?
