I have had this little guy for probably 4 or 5 years. He was a lot larger, but he fell off the porch last summer and this is all I have left of him. Not sure if it is cactus or succulent. It is in a 3" pot so it is very small. I don't want to lose this last piece, so need to know the best care, light, soil etc to help him regain his beauty. I currently have him sitting about a foot under double light tubes. In summer he is outside in partial sun. I only grow C&S and amaryllis and am an expert of nothing. lol Any help would be greatly appreciated.
