Water Gardens — Corkscrew rush

I AM growing the 'corkscrew rush' in my pond. It sometimes gets brown stems in the middle. Any ideas?

THE corkscrew rush, Juncus spiralis, is a true water plant and does not like to dry out for even a short time. This is the most likely cause of the problem, although it may be pot bound as well. This rush will also appreciate the occasional feed with a water plant fertiliser.
