I have a very large plant that I have repotted several times to a larger pot, but now I want it to get no bigger than it is now. Should I divide it? I would think that would work best, but don't want to kill the plant.... The other choice would be to restart some of the leaves, but then it would take forever to bloom again.... What do you suggest??
I think that you are spot on. Dividing would be the best way to deal with this. You can even give away the divisions to other, to share the plant. Here is an article on the care of these: https://www.gardeningknowhow.com/ornamental/cacti-succulents/fishbone-cactus/orchid-cactus-care.htm
