What soil are you using? Could you add a couple of pictures?

Hello people. I think I will start a project as it is a common point of questioning and seems to be a topic worth exploring. Pure mineral soil mixes I will endevore to retrace a few years of online reading around this. I will add links and any references I find I think are relevant, please feel free...

Ps. I kinda thought some more on this. Take a look at this search for images, see how many are growing from pure stones. https://www.google.co.uk/search?q=cacti+in+habitat&prmd=isvn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi_n7PvqIjaAhVSbVAKHXf7DvEQ_AUIESgB&biw=360&bih=560 I ...

It has fairly absorbent ingredients including sandstones, mudstones, pumice and a couple of other volcanoce bits and Tesco non clumping cat litter the baked clay type. I don't really pay attention to how often I just water once they are dry right through. I guess weekly or even more often if it's ho...

Rot from too much water. Cut it off where the nice green stem is and sit it in a pot of dry grit and wait. It should re-root from the bottom once roots have formed water a little to begin with gradually increasing. I would try a different soil mix with more grit, rocks etc rather than peat or other ...

No heat in the green house, they have to though it out so I am now more carefully when acquiring new plants they need to take the low temperatures but it's working well I still have the little cold frame I used to use but now just my 2 big trichocereus live in it. Here the garden minus the snow. It ...

This infection usually starts at the apex in amongst the fur and spines in the growth tip and spreads down. It happens if there is damp sitting there for a while. It probably was not great being pulled out of the pot but not it's demise.

I had this on a astrophytum myriostigma and it was fatal. It's a fungi infection I cannot remember the name of it off hand but it's talked about in and early xerophilia issue. As said above cut it off, slice it like a cucumber cleaning the blade between each cut until the black is gone and all you s...

Yeah it's just a large cold frame so you are seeing the panels. Here it is from the outside 20180322_090926-1024x770.jpg I put it up on bricks to keep it out of any standing water and give it more ventilation. It worked really well this winter. I just cover it with a tarpaulin during the wettest mon...

Yeah the echinocereus' always look great very bright. The aztekium was it's first time flowering I had 5 in total last summer. My favourite of the year was the acanthocalycium glaucum it's has the most satisfying blooms. Very chunky furry and bright. My echeveria agavoides is pushing up a flower sta...

Yeah there is not really much out there. I managed to find only a few online references to it when I got mine. Mainly just sellers of the plant. If you go to http://lophophora.info/lophophora/standort.php?karte=coa&staatname=Coahuila They list lophophora fricii albiflora found in viesca, I assum...

Last weekend 20180318_105225-1024x768.jpg 20180318_084916-1024x768.jpg 2 weeks prior 20180302_134550-768x1024.jpg 20180302_134506-1024x768.jpg Annoyingly I had water them for the first time this year between these two snow storms. About a week after the first bout of snow the weather was glorious I ...

Here is some pictures from last summer that I didn't get round to unloading.

I agree, lophophora viesca. It looks just like mine. I assume they are a location specific variation of a fricii. Mine has pale ivory coloured petals with a hint of a brown midstripe. Big flowers compared to other lophs.

Your collection is looking beautiful as ever.
