myrio koh-yo white forms

[Carlo & Daniele]

usually koh-yo are nudum forms, but crossing them with onzuka or other plants you can obtain nice white koh-yo forms:



this is the bottom part of a graft producing nice coloured offsets:

Very nice plant !

My Onzuka-khoyo was very good once but changed appearance.
It was good

Yes Frank, when they are young they are better, but some of them mantain a good appearance.
These are own roots ones, starting changing colour:

really a  greath plants and it show some really realy greath future possibility!
if you have seeds of this plants or from the same cross....let me know, i'm really really interested!

[Carlo & Daniele]

Mario you are a lucky man, your plant is wonderful!

[marazz53]

Hi cortona, THANKS for your appreciation. Yes, I will let you know. This minute, I just went upstairs, into the greenhouse in the cold (8C) to check the history of this plant for you. The seeds came from C&D (Italy). I sawed those seeds on 28-4-2010, grafted it on Hylocereus undatus on 26-7-2010 and than I regrafted it again on 17-5-2011 on Trichocereus macrogonus, a solid TURBO engine. Happy???

[marazz53]

Hi C&D, thanks. As I told you the last time in Picasa, you call me lucky if I win the super 5, or a big lottery. By the way, that is one of your seeds. Two came out like that, but this is really wonderful and I like it. THANKS...

[cortona]

realy happy;-)
let it grow! and if you have two of this.....cross it cross it! i think all us are curius about how nice can be the soons of this plant!

few other nice plants:

Very nice plants! I see that many of your seedlings are grafted on selenicereus. How does this stock grow  compared to pereskiopsis and hylocereus?
Good work

[Carlo & Daniele]

hello Dan, growth on peresk is stronger at the beginning but when it loses leaves it is quite calm, and with the initial pumping you can notice characters then after disappear. Selenicereus is more stable, but growth is slower. Personally we do not use hylocereus cos it's very weak for our weather.

[danskibsted]

Thank you for the explanation! I like the idea of more stabile slow growth, because then you don't have to regraft.

Hello danskibsted, I read some article that Pereskiopsis is not very good stock to Astrophytum seedlings. And from my experience I can say that its true. I obtained some selenicereus'es and hylocereus'es and I have very high probability of success with Selenicereus. Even 2 years after grafting, grafted plant is very vital. Comparing to pereskiopis, grafted plant is not making offsets as it is on Pereskiopsis. I like Selenicereus most for young seedlings, older plants could be better regrafted to Eriocereus, Echinopsis eyriesii or Trichocereus pasacana. -> or completely degrafted.

Hi Tokra,
Thank you for your message.
I produce 200-300 pereskiopsis grafts every winter. I find that astrophytum grow very well om pereskiopsis, if you remember to give the pereskiopsis stocks the correct treatment regarding fertilizer and water - They do not always like to be treated like other graftingstocks or cacti in general. I usually see the first flowers within 6-10 months from seed, and a good steady growth for the first year untill I regraft on more solid stocks.
I guess stocks don't behave the same way in all climates - some stocks work for me and not for others (:
I am looking for another stock for seedlings that can take lower temperatures than pereskiopsis, since our winters are cold an long. I guess selenicereus is more cold-resistent?

[Carlo & Daniele]

I think so yes, no spots on almost all the grafted plants, peresk usually have some spots, but inside are green.
This winter we lost principally peresk, not so many selenicereus.
Minimum temperatures in the greenhouse about 4-5 °C.
