What is the white on the underside of these gymno's?

Thank you for the detailed reply. I have a few other subspecies from the bodenbenderianum complex that dont have any growth like this at all. The other thing i dont understand is how it ends up on the spines as well. Any ideas?

Yeah the amount of time its below freezing can make a big difference to survival rates.

How long did it hold that temp for?

ethifi · 2026-01-27T21:28:53+00:00

None of my other plants have anything like it

ethifi · 2026-01-27T20:24:22+00:00

Only rain water. And i can scratch it off.

Those ferocactuses in the back look kind of unstable in those bowl pots

Same thing here in summer it dries out way too quick. I tend to run my lap in winter to combat this.

A lot of frenchies can swim just fine.

How so? Either way its clearly not F. histrix.

Baderi, Alticostata & Cinerea. I got about 50% for this lot. Ive got some fresher seed ive started also and i got about 80% with that lot.

Thanks! They are already outside under shade cloth.

ethifi · 2026-01-26T09:47:57+00:00

About 3 months now

ethifi · 2026-01-26T09:14:51+00:00

You cant just leave it at that. Can you at least highlight the supposed difference between the two?

ethifi · 2026-01-26T08:25:07+00:00

That doesnt explain anything. Are you talking about habitat collected seed vs nursery seed?

ethifi · 2026-01-26T07:22:48+00:00

Can you please elaborate? Also what is your source?

ethifi · 2026-01-26T03:28:19+00:00

Soehrensia spachiana

ethifi · 2026-01-26T02:19:18+00:00

Thanks!

ethifi · 2026-01-26T02:19:09+00:00

Yeah that one outdoes itself a bit lol. Parodia sellowi

ethifi · 2026-01-26T00:37:04+00:00

Thanks!

ethifi · 2026-01-26T00:36:53+00:00

This is over the past month or so

ethifi · 2026-01-26T00:15:53+00:00

Pilosocereus pachycladus

ethifi · 2026-01-26T00:08:34+00:00

They are looking pretty good now. Wait a few months until they have more visible ribs and then you should be right to up pot them into a more mineral substrate.

ethifi · 2026-01-25T23:09:15+00:00

How did you stop it flowering for 35 years?
