Degrafting

Great results, happy flowers.

How long do you typically need to wait before seeing some sort of rooting from the scion? I know this likely depends on plant size and a host of other factors, but if you had to estimate?

I followed this procedure as closely as possible with the cactus I had to degraft from my other thread and I now have it sitting on top of some of my soil mix. The vascular bundle is very dried out now and I suspect it should be dead by now.

Should I occasionally moisten the top of the soil to promote roots to form to hunt down the water or should it stay absolutely dry until roots form?

[Hanazono]

As I described in the post on 26th August last year, the vascular bundle had to insert immediately into wet potting-mix without drying.
The vascular bundle should not be dried out.
Dried out means it has been dead.

You have to move to a normal degrafting now.
- Remove the vascular bundle completely
- Dry the scion for 2 weeks
- set the scion onto the potting-mix keep 2 more weeks without watering
- start watering and continue if the potting-mix dried completely

I think there are various ways of rooting but I will do as above.
Roots will be developed 1 month after 1st watering.

Hi hananzo. I don't know if you wrote it already. But if I cut off a pereskiopsis graft and want to reboot the shorter pereskiopsis stock should I let it dry up some days or do I put it in the soil directly? Kind regards André

G'evening Awdre

Pereskiopsis stocks also should not be dried, insert into wet soil immediately after cutting.

Guys what is the average life span for a hylocereus stock? i have many grafts on hylocereus, and i prefer to wait more than degraft.

[Hanazono]

It depends upon the climate of winter in your place because hylocereus is not tolerate against to cold climate.
The average life is 7~8 years in my place where is no snow and no ice in winter.
The death of hylocereus comes up suddenly within a week as shown on the attached photo.
The soft tissue has died at this stage but the vascular bundle has still been alive and so you still can go to degrafting with a short vascular bundle.

I live in Egypt so the temperature does not go low this much
Here it is some of my grafts

i am happy to know that the sudden death for the stock does not affect the scion
but i bought some Gymnoclacium last year grafted on hylocereus and its got rotten from the connected area, so maybe it was infected some how.

Did you graft that Aztekium again or you waited for the own roots ?

[Hanazono]

I went to degrafting with a short vascular bundle of Hylocereus.
The attached photo is the prepared scion before rooting.

Roots will come out from the vascular bundle initially very soon and rely on them for some years.
Roots will develop from the scion just before the vascular bundle die.

Thank you for the informations!

May i learn how big is that Aztekium ? I received one few days ago, it's around 2cm,grafted on Echinopsis sp. Should i wait for it grow more to degraft it ?

Here is my Rebutia heliosa after degraft, as i remember the roots delevoped around 1 month.

[Hanazono]

The cactus is multi-heads but the largest head is 5 cm in diameter.
The rooting of 2 cm in diameter cacti is not easy for any species.

I do not know the species of your Aztekium but their rooting are not easy.
A. ritteri: I tried many times without any successful results. ( and so I do a degrafting with short vascular bundle.)
A. hintonni: Under rooting trial, I think it is possible if the cactus is more than 3 cm in diameter.

The rooting of Rebutia species is easy, I think.

Sorry i forgot to mention, it is Aztekium ritteri.
Considering its rooting is not easy, i wont degraft it.

Guys i tried this technique with Selinicerues as stock , some worked fine, others got rotten, now i have two more plants just lost their main stock , the selinicereus turns yellow, and vascular seems fine, can i keep it stand on this vascular ? instead of digging it into soil?

I degrafted 3 of 2 years old Ariocarpus and prepared for the rooting.

Scion: Ariocarpus retusus v furfuraceus cv Suguri cauliflower
Stock: Pereskiopsis
Type of degrafting: normal one
The grafting joint using Pereskiopsis stock is embedded into the scion but any elements of the stock have to be removed completely for the normal grafting.
The joint end of the stock is T shape.

1. Degrafted scion with a short stock

2. Cut and open of the scion bottom as same size of T end

3. Split the stock in 4 and remove one by one
A large cavity is formed on the bottom of scion

4. The cavity is filled up by drying agent, garden-lime and will keep for 1 week.
