Fibre Optic Grass care - anyone grow these?

I've got some of the above in my wildlife pond.
I've read they should be tidied up in autumn so I trimmed off bits that were in the water last autumn, do I need to do anything else with them as they still look a bit tatty?
Thanks

As my dear late Mother would have said " Never trouble trouble, until trouble troubles you"
I just wondered if I should be trimming anything off.
I'l leave them alone

I'll give it a comb through
