Some of my seedlings

[Nino_G]

I decided to share photographs of some of my seedlings of various age. First the young ones (1,5 - 2 years of age):

Some seedlings of the similar age in communal pots/trays:

Some of the older seedlings (mostly 3-5 years old):

Do you keep any of the hardy species in an unheated greenhouse during the Croatian winters?

[Nino_G]

All of them overwinter on my balcony, without any protection.

[Aiko]

Really? Also the Geohintonia and the Aztekiums?
What kind of temperatures they have to endure on freezing nights?

[anttisepp]

Beautiful very healthy seedlings, respect!

[zpeckler]

Dude those M. perezdelarpsae's are looking awesome!

[keith]

All looking very good

Some of my favorites!

Well grown as well:







So you treat the Navajoa peeblesiana any differently from the rest of your seedlings?

[C And D]

Really great plants
good work

[Fatich]

Well grown plants!
Grown outdoors?

[Nino_G]

Thank you all for the kind words!

If the night temperatures fall below -5C (23F) or if highest day temperature remains below freezing point for several days in a row i bring them inside, but that happens only rarely.

They are treated the same, except they remain outside regardles of the weather conditions. Last winter they were even covered in snow.
I have spoken with very experienced Czech grower who specializes in growing cold-hardy North-Americans (mostly Sclerocactus/Pediocactus/Navajoa/Toumeya complex and numerous varieties of Echinocactus texensis) and he suggests that Navajoa is very difficult, if not impossible, to maintain on it's own roots and he grafts all of his plants on short cold-hardy Echinocereus rootstock. He said that he managed to grow plants from seed to maturity but with very many losses and death can happen suddenly with no aparent reason. My seedlings are survivors from sowing small package of 10 seeds (seeds were sterilized and subjected to scarification to enhance germination) - three seeds germinated and two seedlings survived to this day. I'm willing to risk and grow them on their own roots, we shall see the outcome...

Grown outdoors?

Yes, on my balcony.

Thanks for providing your current treatment for this somewhat difficult species. If you obtain more seed, I hope you get a better yield. Finding seed is either expensive, difficult to import, or too risky to gamble ordering. I'll report back if I locate a good source

Seeds are indeed expensive. But not difficult to find. Many of the Czech seed lists offers Pediocactus peeblesianus. If they are willing to send some seeds in a bubble wrapped envelope (and not in a box), I am quite certain they can easily pass customs without difficulty.
