Sorry if that isn't how you spell it. I've got a large red cordyline in a pot in my garden - bought it last summer. It's survived the winter but is absolutely moth-eaten - lots of the leaves are skeletal. There are a couple of new leaves in the centre. What do I do with it? Shall I just hack it down and if so, to where - right to the bottom? Do I just leave a stump? Ideas please!
