Jordi

Hi Jordi, last sping I bought a graft with two branches and tried to root one (this one in the picture) withouth success, but it flowered. Because I do not like grafts I am now trying to root the second, which however did not flower

ciao

Bruno, I only once succeeded in rooting a Yavia offset. It then lived for about 2 years and died. Now I have a seedling grafted on Pereskiopsis which air-roots like mad but I don't dare cut it off the Pereskiopsis and plant it in soil.

what sort of soil substrate does Yavia grow in? Any idea why it just won't grow on its own roots? I find this fascinating, dealing with Echinomastus and a few other touchy ones.

Looks a bit like shale to me: http://www.cactiguide.com/cactus/?genus=Yavia

Hegar,
How can you be that sure your Harrisia jusbertii is a South American plant?
It hasn't been found in habitat yet!

wow, those Yavia habitat pictures show a strange mix of layered shale and very sandy, gritty, probably densely packed soil. Interesting.

Ha! I thought that too. Think we can let this one slide?

Hi Jordi,
i didn' t know it' s so difficult.

This is as it was

the cutting didn' t root but flowered. I should perhaps try to graft what is left.....

btw here is an interesting article on Yavia http://www.google.it/url?sa=t&source=we ... Qcz60fISQw

I'll take any that you no longer feel a need to keep

Especially the Acanthocalycium IMG_1243

Cheers ... GeneS
