Re: New Argentinian Pyrrhocactus?

Very interesting, thanks for the cladogram as well!

Also very intriguing to see Neowerdermannia and Yavia in the same clade.

Re: Post winter watering

I never spray cacti because they aren't orchids neither bromeliads, no practical use at all. I water them when they are moved to greenhouse and temps are high enough, never give them "some drops" but good amount of water. Better later and much than earlier and little. Consider for example...

I would also say Lobivia, impossible to say at first glance what species it may be and/or if it's a hybrid
This comment needs correction though, since the DNA-research of Schlumpberger et al. in 2018 Lobivia is no longer lumped under Echinopsis

Re: Post winter watering

In my experience you should never water mildly, soaking your plants thoroughly with every watering makes much more sense. Of course making sure that the soil completely dries between waterings. This applies mid-summer as well as in early spring. However, it is generally a good idea to spray your pla...

Re: New Argentinian Pyrrhocactus?

Very interesting plant and description!
I have never heard of there being a correlation between Pyrrhocactus and Neowerdermannia before though.
Have I missed something there?

Re: What are you sowing?

Pretty much the same here, I actually count on not too many seedlings surviving.
Which is fine, because I need three plants for my collection at most usually.
I take my one to two year old seedlings that I don't need to one of the monthly meetings of our local cactus club and give them away.

Re: What are you sowing?

Honestly? You can never be completely sure of course, but chamaecereus without a field number are a bit of a red flag to me
Simply because these get hybridized so much

That said, the first one does have locality data, so that is a bit comforting

@nino_g actually that should be Reicheocactus famatinensis now, since Schlumpberger recombined it

Re: Arjen's 2017

I live in the netherlands so I am not really familiar with your kind of conditions, on hot days they may be a bit like the conditions in japan. that may especially be the case because I keep most of my cacti in my greenhouse where it can get very hot. I use a special kind of paint that blocks a good...
