Here is another cactus that I have that is wrinkly. It has no Measly bugs, or whatever those parasites are called on it. I have had it for close to a year and have not potted it, so I am wondering if that's the problem. I water it once every two weeks- maybe that's too little or too much water , or maybe it's getting insufficent drainage or something. Any tips on how to save this guy?
