after this topic on new sowings,

now it's time for grafting!

are you grafting too in this period?
the graftings start to grow!

p.s. sorry but the glass is a bit dirty...
To me interestingly what cultivars are graftied ? , more soon to see result. I very much not patient and curious :)
some nice fukuryu, onzuka with big V-marks, superkabuto alps and on the back ariocarpus cultivars...
Carlo and Daniele,
Your new work looks wonderful.
Could you explain details of how you achieve such good results?
Do you use a weight on top of you new seedling and do you put them into humid tray quickly after grafting or do you wait 12 hours?
Your advice is much appreciated.
With regards

thanks Lee!
Essentially we use razors blades for the cut, we clean them with peroxide.
You have to be careful to make a neat cut on the peresk. You can decide to cut it on the top and put the seedling covering all the cut surface or cut at a bottom part on the peresk and put the seedling on the side (like in the photo)
Then you cut the seedling, with astro you can do it from 3 days to few weeks old, with ario you have to wait a bit more because at the beginning they are quite small, two three weeks old seedlings are ok...
Then you put in a humid environment for at least 3 days but you can leave also for a week.
Then you remove the gratfings from the humid environment in order the surface dry well and in a couple of days you start watering.
If someone has some own tips please post them here.
thanks
Hi Carlo and Daniele,
Thank you for your help and guidance.
It is really interesting that you use Hydrogen Peroxide for cleaning the rasor blades.
It it good that you make Perskiopsis grafting with no weights and just rely on the sticky surface.
Do you think it is possible to Pereskiopsis graft Astrophytum seedlings that are old? Perhaps the slow to grow seedlings that may have interesting genetics.
I have only read about Pereskiopsis and new young seedlings.

Hi Lee,
yes we do not use any weight, we forgot to write it...
In the past we tried grafting also 1 cm offset of adult plants on pereskiopsis using a weight on it, but since peresk is not a permanent stock is better to graft bigger plants on other stocks.
If I remember well we grafted seedlings also 3 months old on peresk, but they were kept all the time in boxes so they where quite 'soft'.
But generally pereskiopsis is used for very young seedlings.
i do usually use 3 weeks old scions. this is what works better to me.
in my little experience i noticed that the most important factor is the condition of the stock. it has to be perfectly hydrated.
the other thing i am trying to evaluate is the use of a cold room for the grafts.
i put them in a shady COLD room(not dark at all), for at least 3 days. (for cold i mean about 18°C)
this makes the contact with the scion surface longer with little drying out, and to me it has better results.
i passed actually from 75% succes rate to about 90% success.
hope it helps...
will show some of mine next days...
Hi Carlo and Daniele,
Thank you for your help and information.
I can understand why you use different stocks for larger plants.
In your sunshine you will be able to grow your stock quickly.
Here in UK with lights, the Perskiopsis are quicker to grow than other
rootstock
It is good that you were able to achieve success with older
seedlings that were soft.
With regards

Hi fanecchissimo,
Thank you for your help and information.
It is interesting to read your findings. I also graft at around 18degC but
I struggle to get good results at any temperatures.
I keep my Pereskiopsis dry before I graft as I heard it stops the seedling being pushed off.
Perhaps this is where I go wrong.
If the Perskiopsis stock is dry after cutting, I use sap from squashed leaves to make it more sticky.
With regards
Lee(inUK)
Usually we stop watering the stokcs few days before graftings, and yes we can confirm, according to our experience too, that it works well putting the plants at a lower temperature (cold room as fanec described).
i do usually water (not a heavy watering) about 2-3 days before, in an artificial light condition...(about 27°C and 13 hours of light per day)
i usually find them good this way.
Carlo, Daniele and fanecchissimo, many thanks for your help.
I understand now from you, that it is best to have the Pereskiopsis well watered but then starting to dry. It then will produce lots of sap.
Cooler temperature perhaps help stop drying of seedlings and slow the metabolism of the Pereskiopsis.
Many thanks

nice work.. i still need more experience on selenicereus to see if i am able to get good growth rate and good winter stock conditions..
Very nice work Daniele, soon you will have a nice forrest of ario's growing (:
Dan
Thanks Dan! I do this work togheter with Carlo, it's quite fast to cut peresk and graft seedlings in two people.
Daniele
Guys professionals ! compliments ... !
It is very good to see your pictures and read your suggestions. Many thanks.
thank you both!
Hey there!
It feels like ages since I haven't visited the forum! I had some issues with my laptop :(
I want to know, what comes after pereskiopsis? how long do you keep them grafted? do you re-graft or what?
Sorry I made so many questions haha, thanks in advance for your answers!
Victor
we usually use myrtillo or harrisia...also tricho works well, depending on the scion.
One problem with pereskiopsis with asterias is that the stock goes into the scion for several cm and so it's difficult to cut and regraft a big asterias. selenicereus, according to our short experience is more resistant compared to peresk.
