Orchid Cactus is wrinkly...HELP!
I am fifteen years old and new to growing plants. I recently have begun to grow an Orchid Cactus (sorry i don't know the scientific name!) I am beginning to worry because it is wrinkling. I will post a photo so you can see what I mean. If anyone could offer suggestions as to how to fix this it would be GREATLY appreciated. Thank you in advance!!!
AND please ignore the pot in the background...that is for a separate project!
