Water Gardens — Fibre Optic Plant

I HAVE tried to grow the Fibre Optic Plant in my pond on three occasions with no joy. They just go brown from the bottom up and die. Any clues?

THIS plant, otherwise known as Fairy Grass or Isolepsis sepulcharis is really a shallow water Marginal plant and is often planted too deep with the result you describe. I recommend that the water is not any deeper than the soil surface. With the right water depth this is actually quite an easy plant to grow and it benefits from an occasional feed in the form of a water lily tablet.
