Almost all seeds are collected in-house, crossing by myself but I still buy some seeds every year from VIC.
Eyriesii is not a parmanent stock but you can keep quite long time.
I may degraft the photo one next spring.
Since grafting joint of eyriesii is flat and so it is easy to degraft. Rerooting is also easier with flat face.
When you graft a scion on Hylocereus, the joint will be inside of scion and difficult to degraft and reroot.

yes, Echinopsis make very good grafting stocks. Below are a pair of Toumeya papyracantha I grafted to an echinopsis hybrid about one and a half months ago. they would be bigger but i went away and they got really dehydrated. echinopsis stocks tend to offset prolifically following grafting but this is easily prevented by removing the areoles as you can see.

Hellos hellos, my kind of discussion. Only 1,5 years of graft experiments in my back.

Completely off topic, but, i really want someone to graft a Carnegia to another stock and see how it pumps up and takes off.

I am planning to do this this season!

Echinopsis eyriesii areoles look alot like Harissia jusberti.

I always like the idea of experimenting with different stocks, but I had failures with a certain Opuntia I used - which was also not practical due to glochids - I did many red gymno attempts, which might played a role in the failures. I saw that A.subulata is very compatible with opuntia family in general. This might also mean that echinopsis might stick very well.

I have used smallish echinopsis to graft slow growers. We see how this goes..



The idea started when I got such an echionopsis and a small ario kotso grafted on it as gifts from a friend..



This is also a great stock. Didn't know what it is , got it unlabeled from a friend but it looked good and it does wonders!! Only two attempts and its 100% and not the easiest cases - one was done in extreme hot summer, outside, most nodirect sun, but pretty hot and dry, no pressure, is the one you see in the photo, only a humidity tent was provided to reduce evaporation of humidity. took easily. Second attempt is much recent: a lopho pup from a echinopsis than roted due to injury [nasty cut] rescued by grafting on unrooted stock!

I had began to suspect it might as well selinicereus, but the suspicion cinfirmed when I say the photos that Cortona suggested.

Needless to say I already have used another selicereus that I haven't even seen flowered that is very common around here, which grows and roots like mad! It is doing very good with astro too!


Monvilea monstr


Gymno


Turbini [you can see an orange scarring on the scion ....]


Astro asterias. I found a stick insect chewing it! Thankfully it didn't damage the central meristem

==============

AND NOW THE QUESTIONS!

Do Pereskiopsis really prefer no-direct light??

and, regarding harissia, it also like less direct too??? It's supposed to be more lasting too. Is this true...?

That might partly explain stalling of lopho on pere grafts in full light, even though in this occasion lopho also might prefer less direct light - that having being said, trichocereus as scions have grown fantastically on peres in direct sun ...

===========

I forgot this one

Just a photo of different stock all scions were same size when grafted. From left to right Harrisia,Hylocereus,Trichocereus and myrtillocactus stock are different sizes so to make it more accurate they should all be same size thought i would share photo anyway.

Ariocarpus retusus scapharostaroides grafted as 30 day seedlings. The two middle ones are grafted onto harrisia sp and the two outer are myrtillocactus.

Great photos cactuscook. Harrisia sure is a great stock

That is really good work you have done there with the different graft stocks cactuscook, I have always wanted to see the results of such an experiment.Thanks for showing us.

Would it matter that the stocks in the experiment vary quite a bit in size?

I agree stocks should all be same size to give a proper indication of growth rates. Thought i would show pic anyway interesting to see different stocks.

Yeh the stock size would make a bit of a difference along with the quality of the graft union. But it probably doesn't totally account for how big the harrisia ones are. Also very interesting is the different effects stock species have on the appearance of the scions.
On advice from Kada's posts I raised a batch of Lamairocereus pruinosis to try as stocks this summer coming. Anyone got any Pictures or experience with this?

It's really a fascinating little experiment. Harrisia definitely seems to be a great choice of stock, since you get the rapid growth of perry without the cactus-on-steroids look.

Now, if only Harrisia were more readily available...

The beauty of harrisia is it can be a permanent stock.

And harrisia gives lots of flowers and early. Ariocarpus agavoides

Whoa that fantastic! I'll get a picture of what pereskiopsis did to an agavoides of mine but I am warning it'll hurt your eyes, just think Jabba the Hut.

haha yes my ario's are looking a little like jabba the hut also on the pereskiopsis
