Hi. I have a moon cactus that's decided to go rogue. The stem has sprouted arms with long tentacles that have very sharp thorns. It's wandering all over my indoor greenhouse. The "moon" part of the cactus is appears to be growing babies as well. It puts on a beautiful flowering show several times a year. I just don't know what to do with these arms and tentacles. At first I thought perhaps they were roots, but they don't seem to dig into any dirt they coem in contact with. I do'nt want to kill the plant. Also, these 'tentacles' appear to have a white milky substanceon them for several days after they appear. There's no odor or anything.

I just want to know what in the heck to do with this thing. It seems happy since I moved it from the little pot it came in into a larger pot of its own. It's just gone wild. I have visions of this thing taking over my house. LOL

Welcome!

Your cactus going rogue might be the thing that saves it. Your Moon cactus is actually a lopsided relationship between two non-related species of cactus. The top is gymnocalycium mihanovichii - a naturally occurring mutant cactus that has no chlorophyll. That means it is not doing anything to support itself and is completely reliant on the bottom half.

The bottom, a Hylocereus, has been beheaded and the Gymno grafted onto its main growth point. That means the Gymnocalycium grows at the expense of the Hylocereus which, literally, works itself to death.

But your Hylocereus is growing! Hurray! That means it will be able to continue to support the Gymnocalycium, without sacrificing itself, forever.

BTW, did I mention that the Hylocereus is probably a Dragon Fruit? It will grow to be about 20 ft long and wide before its done. Whistling

You have plenty of time. They do grow large, but it takes a few years. Hilarious!

You can spend the time rearranging the furniture so it will fit. Rolling on the floor laughing

As the Gymno puppies grow, you can graft them onto different parts of the Hylo. I've always wanted to do that.

Thanks for all the encouragement! I will set to rearranging my furniture forthwith. Thankfully, I have high ceilings. At the rate this thing is growing, it will take over most any day now. (I think the cat suspects something...he spends a lot of time in the greehous area.) I don't know much about grafting...but I can learn. I bought my friend one at the same time, but hers died already. I had this guy under a grow light for a while and mixed some plant food into his water once. That's when he really started to grow. Seems he grows an inch or so every week. I'm sure that's just in my head...but he IS getting longer. This is just wild!! I never expected he would get a mind of his own and decide to grow. But if you're saying this is a good thing, then we will forge ahead as is.

Here you all are...out there in sun country...I'm living in NW PA. Snow much? Nah...a few feet a year. But I'm happy...Cactus is growing and appears content. Have a happy day, Ladies...and thanks again.

Oh, I forgot to aask...in all the excitement about rogue cactii. What are those root-like things? They look like tentacles, don't burrow into any dirt they come into contact with and they tend to get this milky stuff along with very sharp thorns. I've tried to not monkey with anything, but those things have me stumped. You can see them in the pictures in my first post.

Thanks for your patience and your help. I tip my hat to you.
