Hi, this is my first post. I have 2 beautiful Christmas Cactuses. They are healthy, they bloom, they're huge and gorgeous. Only thing: I wonder about their dirt/roots. It looks really old and the plant "roots" (like the base of the plant that comes out of the dirt) is showing and I wonder if they need to be repotted. They are old plants, maybe 7-10 years old. I don't have a green thumb at all. I'd hate to disrupt them unnecessarily and kill them. I tried to attach a photo but was unsuccessful. So I guess my question is; do you think it's ok to leave them alone as long as they are flourishing?
And what would be the symptoms when they DO need to be repotted?
Thanks, hope my question/s make sense.
