Winter grafting

[robinast]

I find grafting aztekium and strombocactus super difficult because they are so small, ...
Dan

Me too, actually - but growing the seedlings on their own roots is even more difficult...

Here is an update from my winter-project:

You're showing the highest flight indeed, Dan! I like 'maruibo' and 'sassanami' the most - though ALL the pictures are great!

[Carlo & Daniele]

great job Dan! the fukuryu and the kikko are very nice

[danskibsted]

Update! The grafts are around 5 months old now:













Dan

[Carlo & Daniele]

very good growth rate love that single headed maruibo (?)

[danskibsted]

Thank you!
How are your winter grafts doing?
Dan

[Carlo & Daniele]

they are doing well, here there are some photos (sorry for the bad quality):













more recent ones, still small

[danskibsted]

Thanks for the update! Very nice work - I like your kikko's.
Your plants look nice and vigorous.

So nice! A great work you're doing, Carlo&Daniele!

I've been repotting my collection last weeks. Quite a lot of an interesting work I'd say. During this, I also removed most of my
winter grafts from under lamps to my greenhouse. Here they go - or to be precise, a selection of them (most of them on the
Selenicereus rootstock; if not, it's specifically mentioned)...

Ariocarpus bravoanus:


Ariocarpus retusus 'Cauliflower':


A choice of young plants from a cross between Astrophytum 'banyaku fukuryu' and A. myriostigma 'kikko variegata/koh-yo':





Astrophytum caput-medusae on the Opuntia humifusa rootstock:


Discocactus horstii on the Pereskiopsis rootstock. Ah, I do love this species so much! 



All the three seedlings from a single seed packet (A. myriostigma 'smyle'):


Seedlings of Astrophytum myriostigma 'Onzuka tricostatum'.
To my great disappointment, only a few seedlings are with three ribs...  Most are four-ribbed, some
have five ribs and a few seem to the 'ball' form. Only the pattern looks nice nearly on all the seedlings.


These funny things also grew up from Onztrico seeds:

Abselutely amazing work Harri! I really like your colourfull myriostigma's.
How old are the digitostigmas?
Dan

[robinast]

Thanks, Dan! Digitostigmas are grafted on the 10th of August 2013 have spent all the time up to now under lamps. I repotted them a few days ago and now, they are in the greenhouse in the natural light conditions.

Some more photos:

Though grafted Aztekium hintonii young plants (here on the Pereskiopsis rootstock) are unnaturally hairy, they look very nice and cute:


Aztekium ritteri on the Pereskiopsis. A couple of plants have an attractive purplish tint while the others are pure green:




Astrophytum coahuilense 'Kikko':


Finally - a so long waited A. coahuilense 'tricostatum' plant:


Strombocactus corregidorae on Pereskiopsis rootstock:


When dreams come true... S. corregidorae f cristata:


Eriosyce sp on the Pereskiopsis rootstock:


Obregonia denegrii - while at first it seemed that all these seedlings will be variegated, it turned out that actually, one of them is
completely chlorophyll-less and the others are pure green:


Astrophytum myriostigma 'Onzuka Kikko' from seeds of C&D. The right front plant is especially nice, I hope that a real beauty
will grow up from it!

[Carlo & Daniele]

thank you guys!

@robinast: your grafts are just great, love the discos, the crested strombo and the onzuka 3 ribs (not so easy to obtain).
btw did you meet the same growth by grafting on selenicereus both on a very short arm (like obregonia) and on a single stock?

[andrea.a]

I cannot say which one is the best, you have really beautiful plants. Great work!
Andrea.

[robinast]

Thanks for nice words!
@Carlo&Daniele:
I can not distinguish the grafts on single stocks from the grafts on these short arms, there's no difference I'd say. At least in case of two arms (I've not tried to use more).

[Carlo & Daniele]

onzuka 3-ribs and a nice ario hybrid

[danskibsted]

Very nice ario!
I got some similar plants from your seeds. I bellieve it was retusus x godzilla.

Cauliflower and maruibo:

[Carlo & Daniele]

omg the cauliflower is super nice
