I bought my Impala Lily a couple of months ago. Our winter comes with relativly dry air and temperature between 5°C to 17°C. The plant whas watered once a week. Spring is just starting,meaning a warmer temperature but not that much. The stem is soft suddenly and one of its roots feels almost hollow. I don't think it is rot and non of tge leaves turned yellow and the fell of. I will replant it again in new soil and maybe move it inside again but I honestly don't know. Any advice will be appreciated.
