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:



It will take several weeks, maybe even a couple of months before I'll start using them.

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.

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 (:

As the grafted Geohintonias have grown a bit by now, I think it's time to post some photos.


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.



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).



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.



Here you can see an approximate size relations (ownrooted Geohintonias are in the middle).



Older grafts (four months ago) on the Pereskiopsis rootstock from the same batch of seedlings, now 14...24 mm in diameter.

Amazing Work! Thank you for the update, it is very inspiring.
You will have a nice geohintonia Collection in a few years.

Great plants Harri, I'm amazed with your success!
How do you store the plants after you have made the grafts?

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.

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.

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?
