They would certainly be happier - especially if the potted walls are not exposed to direct sunlight. Pterocacti love light but appreciate a cool position for their roots. We have in the past lost plants because the roots got too hot.

Re: Pterocactus - Jewels of the Cono Sur [download]

Thank you very much for your kind comments. We very much hope that face-to-face meetings will be possible again soon - Coddington is probably too early this year. We have been thinking for a long time whether to offer the book as a printed work or as a pdf for download. It is difficult to estimate h...

Re: glad we are back

Thanks to all who have worked hard to get the website up and running again.
That must have been exhausting and nerve-wracking hours.

Re: Austrocacti

It's an old discussion between Herman Vertongen and myself. He says some are self-fertile and I say they can be partially stimulated by stimulus pollination. (I hope you can understand what I mean, in German we call it "Reizbestäubung".) I believe that without external stimulation, nothing happens. ...

Re: Maihueniopsis ID

Hello, Mike,

Re: Austrocacti

Nobby, what do you think my A. ferrari is? Your photo reminded me of an A. hibernus that I bought many years ago here in Germany - see photo.

Re: Austrocacti

Unfortunately, A. ferrarii belongs to the species that are not so easy to grow from seed. But if you already have seedlings - congratulations and good luck.
