thanks for the link hellonasty. great
little doc.

I have thought about Selenicereus for a while - I have some
started S macdonaldiae and S grandiflorus. mainly
macdonaldiae. some grandiflorus.

While I was cutting them up I did notice how had they were to cut up.
thanks for bringing it to my attention Cortona.


macdonaldiae

My pal has loads of Aeonium undulatum,
(pic here.. http://palm-trees.org/Kew4/Aeonium_undulatum.shtml)
which he propogates like crazy..
I havn't chopped the rose of one for a look yet, but it seems to me that it could be good as stock.. Anything to suggest otherwise?

I believe - others may correct me, though - that you cannot graft cacti onto succulents. Nice idea, though.

Don't let this stop you from experimenting though Lachy.
Every rule has exceptions.

No, you are correct Lachy, although it may be a good stock for a Succulent scion? I wouldn't know though, I only have about 4 Succulents and a couple of hundred Cacti

You're modest.

Well, if you could find something with vascular bundles that could be aligned with a cactus scion, I don't know of anything that would stop it from grafting. I'm no expert on plant physiology - maybe someone could help me out here - but would attempting to graft a cactus scion to something from outside the cactaceae provoke some sort of fatal immune response in either the stock or scion?

I imagine that the two plants being united would have to be pretty close - I don't imagine that you could graft a cactus to say a rose or citrus stock - so maybe some succulents might be compatible?

A good way to look at it is like human blood types. If you need someone elses blood and your blood types is 'O+' and they have 'AB-'. Your body will reject it.
I guess with plants it is the same case.
Most would have thought that Euphorbia sp. were close enough to the Cactaceae family but to my knowledge they can't be grafted together.
I guess for the bonding process to work there has to be a certain likeness between the two plants and succulents are fairly distantly related in this regard.

There are always going to be grey areas, I just don't know most of the them.

I don't have a great knowledge of biology either, so I'm sorry I can't give you a scientific explanation.

stick to common principles until you can at least graft to cacti/cacti - or you won't know what you are doing wrong.
(just my view is all)

Has anyone tried Echinopsis for grafting? as a stock? I've heard rumours it not bad, and rarely any rot problems.... I was also curious if anyone has ever experimented with grafting to fresh offsets on T pach/T Brig. I notice they always seem to have a real burst of growth initially as an offset but then slow down again. might be a good experiment to get super fast seedling growth.....

Hmmmm just share my thoughts.

Echinopsis... you mean the round ones, not the trich renamed echinopsis?

Yeah, not the new taxonamy where tricho's are now echinopsis. BAH! why they have to make it so confusing. Yeah round stuff like Eyriesii I knew someone would understand me.

Echinopsis eyriesii is a very good root stock for grafting.
You can graft form a large scion to a small seedlings.
You need around 2 weeks of preparation to graft a small seedling on eyriesii.
The charcteristics of the stock is:
Early flowering
Many flowers
I am away form home and I can not show the photo.
I can show you a photo of Ariocarpus grafted on a eyriesii when I came back to my home.

The attached photo is an Ariocarpus retusus v furfuraceus cv Seiji. Stock is an Echinopsis eyriesii.
I grafted a small pup 4 years ago. The current size is around 13 cm diameter.
When you graft a small scion including a seedling, you need 2 stages of stock cutting.
1st cutting: Cut holizontally top slightly and tapered top area ribs.
Waiting around 2 weeks. The top is regrown but the diameter of regrown part is small.
2nd cutting: Cut top until a vascular bandle appeared.
Since the daiameter of body and vascular bandle at regrown part is small, now you can graft a small scion.
You can see the 1st cutting on the stock in the photo.

Thanks Hanazono,

Appreciate you shedding some light on that one, id been told a few times it was a good stock but have never known anyone to use it, amazing to see just what one can achieve in 4 years. Did you cross yourself or obtain seed/seedling? fantastic CV. How long would you keep it on Eyriesii stock before it would need something else.

Thanks for the instructions, I will have to run some trials and error experiments I have plenty of Echinopsis stock plants. I'll play around and get the idea.

Cheers
