My husband just bought me this yesterday trichocereus grandiflorus hybrid. And I want to know if I can graft a moon cactus to this plant and can I separate the trichocereus grandiflorus hybrid now or do i have to wait until it flowers?

why would Confused ...... no. just no Sighing! . The plant is too big to graft to anyway(try a thinner cereoid, like t.pachinoi, or myrtillocactus, or plain cereus), its already developing fruits. Itd be a waste to sacrifice a rarer ,more expensive, and a more beautiful plant just to grow a moon cactus- which you can find in regular purple specimens with roots.

That is a really pretty plant and those aren't fruits, they are buds. The show hasn't begun yet. Someone in this forum does graft cactus; I will see if I can find it and post a link. Personally, I wouldn't graft anything to it or divide it. Part of the beauty of Trichs is the multiple stems with flowers on all of them. When you graft, the growth point of the recipient cactus is replaced by the (in this case) Moon Cactus. You would be better off looking for a Hylocereus (Dragon Fruit) to graft to.

Here is a Trichocereus grandiflorus I had in my garden in CA. They aren't rare but they are absolutely beautiful when in bloom.

PS: Couldn't find the link. Anyone else know where it is?

You would have to find a pretty big moon cactus to graft onto that Tricho. I'd bet that anything 'moon cactus' of that size would probably have gotten there on its own roots.

Also these Trichocereus grandflorus hybrids are extremely aggressive offsetters, so another reason why they are not that good to use for grafting. As you can see they offset essentially at or slightly below soil level, which means that if you'd take one of those to try and graft with, before you know it your grafted cactus would be drowned out by much larger Tricho arms.

Another decent grafting base in addition to the few that Stefan mentions is Trichocereus/Echinopsis bridgesii. for A moon cactus you'd be looking for something that is not too massive and something with not as many spines is also a boon.
It is what it is!

Harrisia martinii and Moon Cactus, Ruby Ball (Gymnocalycium mihanovichii cv. 'Hibotan') both have the synonym Moon Cactus.

If the latter is the plant you are referring to then I would be a little doubtful. Remember the people who graft these colorful mutants will have done a great deal work in deciding which rootstock to use.

All that said, why not remove one of the larger offsets, allow it to root, then do the graft. Just because it is not generally done, doesn't mean it can't be.

Have a look at the grafting page, The thread "Grafting cacti" in Cactus and Succulents forum or https://garden.org/thread/view..., where there are E. huascha/C. repandus seedling scions grafted to C. repandus.

moon cactus is usually a gymnocalycium mihanovichii. that being said, there are lots of cultivars, most of which grafted, and a lot of them needing to be permanently grafted to survive because of a lack of chlorophyll. However, no pictures of the moon cactus were posted, and there is a probability that it could be another plant , by mixing common names. So i concur, post a photo of the so called moon cactus.

This is a variant of said gymnocalcium, f rubra ,cv hibotan, purple form.Im trying to de graft , or make it grown on its own roots. The red forms, the orange, the yellow and the pink forms, cannot be degrafted, due to the lack of green matter/

As for the harrisia bit, harrisia are a better grafting stock than most common plants anyway....

I believe yours is just Gymnocalycium mihanovichii. 'Hibotan' is cultivar of G. mihanovichii and it encompasses the "man made" ones. The purple form (as you referred to it as), is it's naturally occuring form. Smiling

Interesting. I wasn't aware Hibotan came in purple.

Are you familiar with Gymnocalycium mihanovichii v. friedrichii?

http://www.llifle.com/Encyclop...

How do you tell that one apart from the purple form of Hibotan? I'm all ears!

Hmmm, well actually, that is wrong. Gymnocalycium mihanovichii friedrichii cv "rubra" often referred to as "Hiboton" are the Moon Cactus that display mostly red. A lot of them do have to be grafted, but not all.

Do you think the act of self-rooting a "moon cactus" will change its species?

Nope. Hibotan had purple variants. This was a grafted purple variant. Hibotan and related cultivars are usually the ones that are grafted. Had a regular mihanovichii, mostly green to pink during stress. it was a tad different . In a few rare cases ive seen a green hibotan, also grafted.

"The cultivar name 'Hibotan' was applied to the first orange-red introduction but it is now often referred to as "Red Cap" or ruby cactus. At least 16 color variants of this type have been described."

https://www.uaex.edu/yard-gard...

And every one of them is Gymnocalycium mihanovichii friedrichii - and if they manage to produce enough chorophyll, you can degraft them. I've done it too. I even have a few that were never grafted.
