I just received this Easter cactus (similar to Christmas/thanksgiving cactus) in the mail. The bottom portion has a white/matte coloration to it, I’m wondering if anyone knows what this is? I have not watered or repotted since receiving it, thought I plan to repot soon. It’s not mushy or has any odor that makes me think it is rot. Could this just be a natural coloration for the plant? In addition to this, I plan to repot because I see some roots coming through the bottom. I bought this plant as a gift for my mother and would like to make it look prettier for gifting. Does anyone have any advice for how it likes to be repotted and cared for till I can gift?
