Degrafting

[Hanazono]

The following degrafting is Ariocarpus cv Shinkawa tama zouge.
I grafted 36 seedlings 2 years ago and lost one.
This ones are bit smaller than cauliflower.

[Hanazono]

12 scions, Shinkawa tama zouge were selected and set in 9 cm square pots for the rooting in the afternoon.

12 of smaller scions, Sinkawa tama zouge were selected and set in 8 cm square pots in this morning.

[Hanazono]

Last 11 of Shinkawa tamazouge went into 65 mm square pots for the rooting yesterday afternoon.

10 Ariocarpus agavoides grafted in 2016 were degrafted yesterday.
1 was in a 9 cm square pot all others were in 8 cm square pots.
I grafted 12 in total but 2 of them did not grow at all and they were removed.

Hanazono, thank you for sharing these wonderful tutorials. I see in many of your examples, you use wet clay granules after removing the leftover tissue from the root stock. What is the purpose of this? Specifically, do you know the content of the clay granules? I am wondering if there is a substitute in other regions of the world.

My gut tells me a wet substrate touching the exposed tissue would lead to fungus or rot. Typically, I have dipped such exposed regions with sulfur or copper powder. It does work in preventing rot, but is often very harsh on the plant. I want to try your method to preserve some of the appearance of the exposed area and minimize the sulfur smell.

G'morning Pereskiopsisdotcom,

I think sulphur is used as drying medium but clay granules is for the rooting medium.

Drying medium:
I use a garden lime for the drying medium.
Garden lime is filled in a wet hole on the scion, which is made by removing stock tissue.
Keep 2 weeks at least and wait drying the hole completely.
Blush off all garden lime in the hole after the completion of drying.

Rooting is carried out after drying hole completely.

Rooting medium:
I use wet clay granules.
I do not know the chemistry of the clay. I used shifted clay base cat litter.
Since water will never reach into the hole by normal watering, I use wet clay granules.
It is possible to use any permeable materials but you have to upside down scion for the setting of root after filled in the material.
Wet cray granules can hold in the hole during this job.

Hi Hanazono,
What is the clay that you use to fill a cavity before rooting? I have been looking for some, but have never seen any 1mm size. Thank you!

[Hanazono]

G'morning Madalyneb,

I use clay base cat litter.
I shoot the product in market and select 1 mm size.

Hi Frank,

Sorry to revive an old thread, but I have some degrafted asterias I received that still have a small dried vascular bundle attached. Would you recommend cutting it completely, letting in completely dry, and then setting it on wet potting mix?

Thanks for all your help!

G'morning Alex,

I do not know what species the original stock was.
I degraft with a short Hylocereus vascular bundle. It should not be dried. A dried vascular bundle can not form any roots.

It is March now. I think you can go to a normal cutting/rooting.
You should remove any elements of the stock completely from the scion.

If you could dry the cutting face of scion completely, you can set it on wet rooting medium.
If you did not have confident to go as above, set it on dry rooting medium and star watering 2 weeks after the setting.

Frank,

Sounds great. They were on hylocereus but the stock is completely dry. I will cut it out completely and let the scion dry. After it dries I’ll place it on wet mix.

Thank you!

I went for it! Thanks for the advice

The myriostigma and variegated asterias have rooted! The big hanazono has no roots yet and the smaller rotted . I grafted some pups from them though.

[Hanazono]

2 off-sets of Ariocarpus fissuratus were grafted on Echinopsis stocks in 2005.
One of them rotted out last summer because the stoch became too weak.
I degrafted remained one in this morning.

The photo was taken in 2006. It was 1st flowering of the scion.

Removed from pot
The stock has turnned to a woody appearence.

Taken off stock
The union of Echinopsis is relatively shallow.

Fill up cavity by drying agent, garden lime
The drying period will be 2 weeks.
