Help! Today I noticed that my Confederate Rose cactus has several brown spots on it. It may have been getting too much sun, so I moved it to a shady spot under some trees. I don't know if that's the real problem, though. One of the leaves has the brown on the end near the spine. Two more of the leaves have small brown spots in the middle on the tops. I checked for insects and checked to see if there was too much moisture, but she was pretty dry. I just watered her last yesterday. I was thinking that she could be sunburned. Does anyone have a clue?

Yes, I can. If you look down on the plant, it looks like a rose. The "leaves" are very thick like a jade plant, and they are very stiff. It has spines on the edges of the "leaves". It's a blue/green color, and it has two babies/developing offshoots on each side of the main plant. if you go to www.cactuscollection.com, you can find a photo of it. The card included with this "cactus collection" plant indicated that it was a cactus/succulent.
