First Time Cactus Owner! Moon Cactus Rotting? SOS!
My dad bought me a moon cactus before I moved today and I would hate to lose it!!
The cactus itself is leaning, and the bottom is dry, and has peeled away. It is hollow under except for the stem. There is also one white spot on the top of the cactus. I assume it is rotting.. but just want to make sure before I cut off the top and re plant it. PLease help :)
