I am new to the Moon Cactus and I am wondering if it is required to graft the cactus? If so how often?
If you have purchased a moon cactus, then you will already have the grafted rootstock. That is the green cactus on bottom.
If you would like to graft your own, then you can use a dragon fruit cactus as your rootstock.

Why does my moon cactus look like this? The stock is very hard,strong, & green. It looks like something is poking thru from the inside out. Its been like this for a few months now and I don't know why. Thank you
It looks like it may be a root rot issue or the graft is being rejected; in which case there is nothing that can be done.

I just recently got gifted a Grafted Moon Cactus (I'm pretty sure that's what it is called but correct me if I'm wrong please.) with a yellow top and I'm new to caring for things like these so I'm not sure what to do. First, there are a few little black spots on the yellow part of my cactus. In addition to this there are, on the bottom of the yellow top part that extends out, spots where you can see it fading? Decaying? It's incredibly lighter than the rest of the yellow and looks dead or dry? It's not much yet but I'm scared that whatever it is will spread throughout the rest of the yellow part. What do any of these spots mean and what do I do to fix this? Is there maybe anything else I'm doing wrong by the look of my cactus too? Also keep in mind this is being taken care of indoors but if it needs to be brought outdoors for any specific reason, I can do that even if it isn't preferred. I apologize for so many questions but I'm fairly young and so new to this and am hoping I can get the answers I need.
Most likely you have fungal issues. Spraying with a fungicide should help. Here is more information:

It states on the moon cactus that I purchased that it must be grafted to survive, not quite sure what that means, does it mean to cut off the babies?Thank you,Deborah
The colored cactus are grafted to a green cactus, usually the dragonfruit, to survive. Those little babies on top will not survive on their own without being grafted to one of the three suitable host cacti. Most people use dragonfruit, or hylocereus, as the green cactus. Since the babies on top do not make chlorophyll, they cannot survive without a cactus that can. These do not occur in nature.

Please help me. I am emailing for help to save my moon cactus - it is rotting from the top and I have absolutely no idea how to save it. Do you have any suggestions? I really want to save it. Please let me know. Thank you for your time. I have uploaded a photo as well.
Your cactus may have been overwatered and has a type of root rot or fungal issue.
Repot the cactus in fresh cactus soil and do not water for two or three weeks. The brown part at the top can be cut out with a sharp, clean knife. Allow the cut to stay dry while it is healing. (Do not water from top.) Since winter is coming on, water only sporadically, when the top 3 inches of soil is dry. A mature moon plant (over a year old) does not need to be watered at all during the winter.
Good luck!

I have a moon cactus whose base rootstock had 75% rot. So I removed the rotten part carefully and have planted it. Now my doubt is since base rootstock is very small, should I regraft cactus on to a new rootstock or is the remaining healthy part (which is very small) enough to sustain the cactus?
I would suggest regrafting. The top portion must get all its chlorophyll from the rootstalk and 25% may not be enough, plus it may continue rotting. Here is more:

I put tea leaves on my moon cactus and i believe the base is now dying. Is there any way to save it or should I attempt to graft the top to a new base? If so, how do I do that. Any help would be appreciated.
