Bought last week as gift. Put in light, watered, left in original pot. leaves have gone yellow some have fungal appearance and died. three stems but one has come away from base. stems look brown and dry. is the whole thing just dying on me?? Is it likely to regenerate once planted ?? Or do I need to just replace it? bought through rhs website. Thanks Hazel.

This sounds like a bacterial or fungal infection. This is most likely caused by overwatering, or standing water, if the container does not have adequate drainage. It is likely that the plant will not make it for very much longer, but you can add wettable sulfur to it to try and bring it back. It will likely do better outside in ground than it will in container.
