I was given a christmas Rose (Helleborus niger) at Christmas, in a pot. As I am in a flat I put it on the kitchen sill which is quite cold and watered infrequently, however it is incresingly yellow looking and unwell. I am wondering, if I plant it outdoors now, will I kill it? Although it's looking a bit on death's doorstep anyway, is there some way I can save it? I am HOPELESS with all indoor plants, just as well spuds look mainly after themselves!
please help.
