PostSubject: Degrafting A. Fissuratus from Hylocereus   Fri Jan 29, 2016 12:20 am

Hi,

Ive read that this is a difficult process and that the fissuratus scion may be hard to form roots. I have read some of Hanazono's posts about the Japanese technique of exposing the vascular bundle of the hylocereus and burying in pumice.

I have a nice Fissuratus hybrid that has a tiny piece of hylo attached, its the little piece that is the new growth, that has been cut at the join to the main stock which was no longer working. I dont know how to post photos here , but if i could work it out i will.

Anyway, should i cut off the green and plant the vascular bundle immediately in pumice and water once a week? Or bury the hylo? (its a tiny thin bit of hylo.)

thanks

I assume the piece of hylo is less than 20 mm length.
You can bury the hylo.

This method is called "dai-tsuki oroshi" which was used by professional Japanese nursery men years ago.

Thank you Hanazono, I was hoping for your expertise. I have buried the hylo in pumice but I have not removed the green tissue. There isn't much green tissue anyway, it's a very small piece, about 20mm.

Should I have cut off the flesh and left the vascular bundle? What is the risk of rot to the scion of i bury the stock?

I don't have access to scoria, but I do have access to different grades of pumice, zeolite, and spongolite. In your guides to degrafting, you mention a top layer of scoria. Would pumice be appropriate substitution? What grade for this top layer for the scion to eventually root into?

Thanks

I have recommended you to go "dai-tsuki oroishi" means with green soft tissue.
There are no risks in relation to rotting the scion even if you bury a short stock.
It may form some off-sets if you remain the green soft tissue under the soil.

In case of "zui-tsuki oroshi", with short vascular bundle, there are no chance to form off-sets.

Since your stock sounds quite fresh, I recommend you to go "dai-tsuki oroshi".

Any permeable materials are all right for the top soil.
