I share this method of grafting that I've been working on for a while. It has ok results. The advantage is that you can graft young seedlings and the stocks only takes a couple of months to produce. Also no annoying spines like on pereskiopsis. Both stock and scions are around 8 weeks old.
Probably not suitable for variegates though..
First cut roots off H.justbertii seedling stocks.

Next rub off the spines.

Then cut roots off scions.

Then rinse with water, dry them, and rub with alcohol to sterilize.

Cut scion and stock and stick together.
These are the left overs..

Put the grafts in a food container with a moist tissue to create humidity and cover with food wrap. After this wait about a week for the grafts to heal. Take the tissue out after a day and put holes in the food wrap to gradually ventilate the container. Treat the finished grafts as small cuttings. Pot them up and cover the pot with clear food wrap with a few ventilation holes so they don't dry out too much before roots grow. After 3 weeks roots should be enough to just treat them like normal H. justbertii seedlings.

Thanks for sharing you experience with this method! It is very inspiring to see your pictures.
So you actually sow both seedlings and stocks at the same time?
How is your successrate with this method?
Have you tried to leave the roots on the harrisia seedlings?
Dan
Amazing results Simon!!
you've inspired me and I think I'm going to try it soon. Thanks!!
I would like to complement Dan's question: why do you cut the roots of the harrisias?
I bet using Opuntia compressa you could even save the left overs!
Thanks in advance for your answer :)
Victor
wonderful work. ;D
Which is the % of success with this method?
amazing !
Well I would have to say that the method is still in the research and development stage and that is why I posted it here so others can try it and we can share our experiences. Last year I did 25 of them and had 23 survive but one of them failed to grow well so 22 out of 25. I was happy enough with the results that I will do a hundred or more this year. It is a good method because stock preparation is quick. Grafting is fast. Growth is much quicker than own roots. It only takes up the same amount of space as seedling production but you can see the potential of seedlings for breeding sooner. I re-grafted the nice plants from last year onto large stocks when they were around 3cm diameter. Larger stocks will make them grow faster. The parts left on the original seedling stocks are now producing offsets that I will also re-graft.
I cut the roots off to prevent dirt being a problem. At first I washed the roots but it took longer and there was not much difference in the time it took to re-establish.
Best to sow the harrisia about six weeks to a month earlier for fast growing species like astrophytum. Harissia seedlings are quite slow and small but once they get going they grow well.
There are a few tweaks. Like letting the stocks and seedlings be dry for a few days before grafting so they stick better. I will know more about the method in a few weeks after doing this years lot.
Please try it and post your results here...
Thanks for sharing your information Simon. 22 out of 25 is very good, and alot higher than what I expected.
I will sow plenty of harrisia seedlings together with my other ariocarpus and astrophytum seeds, so I will give this method a try and post the resulst here in about 2 months...
Dan
wonderful %.. i will maybe give it a try this winter!
were do you guys find harisia seeds in large numbers? can yo just give me a tips or two?
Thank you for pics and suggestions, I'll try some seedling on seedling graftings, the results are beautiful, better looking than graftings on pereskiopsis.
Andrea.
I tried this method for the first time today. I used younger plants than simon, but besides from that I did exactly as he has shown in this thread. The plants are 5 weeks old jusbertii and 2 weeks old ariocarpus cultivars/hybrids... The small grafts seem to roll around very easy, but besides from that the grafting operation was easy.
I have plenty of more harrisia seedlings... if this turn out possitive, I will produce some more.

Hi Dan, nice job! The method you used is called "hypocotyl graft" and I tried it years ago. The beauty of this type of graft is that with the growth no longer distinguished the stok, and the plants seem to own roots. Let us know how to proceed!
Thank you Carlo. How was your success rate when you tried the method?
Dan
At 10 I had managed 7. The hardest part for me was the vegetative growth after grafting.
Any new pic from Dan?
Andrea.

Hi Andrea,
I will take some pictures again soon. The plants are now established in their pot, and has just started to grow. I still have 6 or 7 live plants from the original 8 grafts.
Dan
Thanks Dan, it is very interesting for me.
Andrea.
Hi all!
:)
My experienсe.
ario on fero
Dan, can you share your results? I'm very curious how it worked for growth - any differences between grafted/non grafted plants? What do you think about making that with Aztekium ritteri and for example Stetsonia coryne (I don't even know if it can be used as a stock)?
Sorry for the late update.
The grafts worked fine, and the ario's started to grow after 1 month. Then I got problems with sciara flies, so I spray all plants with an insectiside. After 14 days all plants started to rot and die:(
I have made some new attempts 1 month ago. So far the results seem good. I will post some pictures when they start to grow.
Dan
Last year I got around 50% success with this method.
Now it is time to try again. This time with larger harrisia plants (1 year old seedlings).

Fingers crossed
Dan
nice work Dan! keep us updated! are you keeping them in the greenhouse or in the propagator?
Thank you Daniele.
I keep them inside my propagator untill next spring. For the next weeks they will be stored inside a humid box.
Dan
Here is a picture of some of the plants from last year. They are around 11 months old now:

Dan
good results Dan!
Beautiful plants, Dan! Which Harrisia species the rootstock is?
thank you (: they are grafted on harrisia jusbertii.
dan
H. jusbertii? The seedlings seem to have longe spines then than adult specimen.
You are right, the spines are long on the seedlings. I have seen this before when I grow jusbertii from seed.
I grew some jusbertii seeds 4 years ago. This year I used the plants for grafting. They give very strong growth - they seem to have more power than rooted cuttings.
Dan

Sounds interesting... I also have some seedlings of
H. jusbertii growing - but still so young that they are spineless.
Spineless? I had seeds from different sources, but seedlings were all very spiny even when only 5 mm tall!
Andrea.
Oh, but my seedlings only start to form areoles - a few days after germinating... :)
This method appear to me more difficult than I thought. After a lot of experiments, I'm finally starting to see good results:

Dan
very good job Dan! keep it up!
Congratulations for the good job you're doing! Can I ask what is the best procedure you found?
I do it pretty much as Simon describes in the start of this thread.
I found that controling the humidity is very important, so the stocks does not rot or dehydrate.
Good luck!
Dan
Very interesting Dan, I hope you've found the best solution! I wonder if you've cut all the roots of the stock or did you leave them?
I leave the roots.
The seedlings are very young, so the roots are very small and fragile.
Dan
For years ago, I've tried this method - but with a small amount of seedlings and, unfortunately, with not that good results. At that time I had a heavy spider mite infestation and as I was not able to get rid of them quickly enough, I finally lost all the tiny grafted plants.
Well, but today I made an another atempt. As I have quite a lot of Geohintonia mexicana seedlings, I will not be especially sad if I'll fail. I grafted 20 Geohintonia seedlings onto Harrisia pomanensis and 12 onto Opuntia humifusa seedlings. I'll keep you informed here how it will turn out.

... on the Harrisia pomanensis seedlings, also grafted and potted today.
Amazing work!
I have had very good results with this method this year. I must make some update pictures soon.
Keep us updated!
Dan
Today, a week after the grafts were made, I checked all the grafted plants. At first glance - the picture is pretty nice, I'd say. :) Nearly all the grafts seem to be promising as the stock and graft are attached firmly together. Only one exception - one grafting stock had started to rot an so, this is a sure failure. I doubt that ALL the others are perfect - but one has simply to wait for a new growth to start. In addition to the Geohintonia grafts I wrote about in my previous message in this thread, I also grafted a bunch of Ariocarpus, Astrophytum and Aztekium ritteri seedlings ont to seedlings of Harrisia pomanensis - total 108 grafts.
Opuntia humifusa seedlings for the future grafts:
(https://www.e-aiand.com/kaktusefoorumisse/humifusafield139.JPG)
It will take several weeks, maybe even a couple of months before I'll start using them.
Very interesting! How is your grafts doing?
Dan
Far most of the grafts were successful - but as a new growth has not started yet, I'll wait with the photos yet.
Here is some of my own grafts. They are 1½-3 months old now. The grafts are on harrisia jusbertii, cereus peruvianus and trichocereus pachanoi. So far they give the same growth.

Dan
Very nice work, Dan! :)
I noticed that a couple of chlorophyll-less seedlings are also grafted very low. Aren't you afraid that their growth will be strongly inhibited as they get the nutrition only from the stock?
Thanks Harri,
For now this is just experiments. I tried a lot of different configurations to find out what Works. The variegata seedlings seem to have the same growrate as the others so far, but that might change in the future. Time will make me more clever (:
Dan
As the grafted Geohintonias have grown a bit by now, I think it's time to post some photos.
(https://www.e-aiand.com/kaktusefoorumisse/geomex0161.JPG)
Here you can see own-rooted plants, replanted at the same time when grafts were made (a month ago). Some growth after
replanting can be observed - but not much as this species is not just very eager grower on it's own roots.
(https://www.e-aiand.com/kaktusefoorumisse/geomex0160.JPG)
Grafts on Harrisia pomanensis show a bit better growth - but the difference, though clearly seen, is not very big. Some
of the grafts are just sitting without showing any growth at all yet and some have died (though the first impression was that all the
grafts were successful).
(https://www.e-aiand.com/kaktusefoorumisse/geomex0159.JPG)
If compared to the ownrooted plants and grafts on Harrisia, the grafts on Opuntia humifusa show the fastest growth
now and are several times bigger. Also, all the grafts succeeded on this stock and all are growing nicely. I think the main reason
is the much bigger photosynthesing area of the Opuntia rootstock here.
(https://www.e-aiand.com/kaktusefoorumisse/geomex0162.JPG)
Here you can see an approximate size relations (ownrooted Geohintonias are in the middle).

Great plants Harri, I'm amazed with your success!
How do you store the plants after you have made the grafts?
Dan
Like below, for a week or so and by temperature around +25...+30 daily and around +22 nightly.
After that I remove the beer glass and put the plants under lamps (while covered with the glasses,
I keep the grafted plants next to the lamps, not directly under them.

very nice

Nice work as usual Harri. It is always interesting to see other growers experiment with this technique!
Keep us updated on those humifusa-digitostigma grafts - I would be very interested to see how they take off.
Dan
By now, I've tried three variants of A. caput-medusae / O. humifusa grafts: with the O. humifusa pads from adult plants, with the 1+ yo seedlings and just yesterday, with the several months old seedlings. The 1+ yo seedlings resulted with an excellent result - but the A. caput-medusae grafts on the adult pads just do not grow nearly at all (even the same-aged own-rooted seedlings are bigger). The pads themselves also do not show any growth (though have an excellent turgor unlike the plants in a dormant state). Let's see what will happen with the most recent grafts on this stock.
EDIT:
Just to show the difference in size of the grafts made at the same time with the seedlings from the same lot:

Hypocotyl grafting is really a very good way to replace the root system by a more vigourous one when the seedling is really small. I would like to try this technique this spring season( Feb end/March). Is it suggestible to try it on Echinocactus grussoni as the root stock and the scion being different astrophytum seedlings?
time for an update ? I would love to see the evolution after one year !
