I have a yellow Crocosmia which has flowered only once - when originally bought. I split it in two the following year with one part directly into the border and the other half in a terracotta pot. Both gave no signs of flowering last year and both lots appeared to have a lot of dark rusty orange colouring on the ends of its leaves. Is this a disease and, if so, what can I do to prevent it if it happens this summer and how do I encourage it to flower (its foliage is quite rampant in the terracotta pot). I have given both a general purpose feed and an occasional potash feed just recently. Thank you for any advice you can give me. Jan
