Hi All: just got this as a rescue from our Gates Society last week. It really said, "rescue," on it. Since Rhipsalis is my very favorite kind of cactus, I was happy to get it as a door prize. It was very dried out, the color is not good, etc. What's the best approach? Hung it from a tree so if can get lots of shade. Should I replant in new potting mix? Thanks so much.
