Title: problems with hylocereus
Post by: Carlo & Daniele on Tuesday, 06 March 2012 - 16:39:29
we kept these hylos in a sunny but cold place (surely some time temperatures went below 0°C) during this winter, this is how they look now at beginning of the spring.

Hi C&D, This winter as I already told you by e-mail, I had that problem too, BUT, with E. jusberti, Myrtillocactus geometrizans, Echinopsis, T. pasacana and H. undatus. I had to put them in 2 large boxes and give them to the garbage collectors. It was a pity, 3 years old stocks, ready to be used as stocks for this year's graftings down the drain...I have to start all over again. Sorry for not taking any photos cos I really was pissed off...WHAT A SHAME to see them like yours...

Hi Mario, it's really a pity to trow away all the stocks.
Hylo between them it's usual the more sensitive to frost, but there are many kinds of spots, maybe yours were different.

Hi C&D, I think it's the cold, we never had this kind of cold in 30 years...

Hi,
Trichocereus pasacana should be frost proof to -10C

i meant that in my climate, if you give anough water and big pots, plants grow quite similar even if not grafted. to me own root isbetter for selection of specimens...

I totally agree with you - Me also prefer more own root plants, they are even better looking than grafted. I graft only because to get seeds quickly, especially from such expensive cultivars like JAPANESE astros & arios are.  :-\  :-[  >:(  :(
