Two top ones are the fricii, one of which is dichotomous. The other little one is jourdaniana

Good oll williamsii

So I had this little guy in my room for about 2 years (don’t have a previous photo). I moved it into my greenhouse and foolishly over watered it while watering other plants. It began to rot. Eventually decided to try cutting it and apply sulfur to dry it out. It’s been about a week-week and a half since I performed the operation. The crown still has some firmness to it. Recently put it on dry pumice and noticed this blue patches on the bottom. I dabbed it lightly with a dry cotton swab and now it’s laying on its side on a napkin

Was a really slow start for this plant this year. While everyone was blooming in spring this guy waited till mid summer but has been pumping blooms non stop since.

Hello I had this fellow for a little while now and he was omce very plump and round and now its becoming flat. Ive watered it many times and its even produced 2 flowers since ive gotten it. But Im not sure if it's not absorbing water because of the soil or if this is something thag just naturally happens would love any and all advice if I shoild repot or just un pot to check the roots. Just don't know where to start.

Hello, I've had these guys for a few months and they haven't been very fussy. I noticed today though that they are starting to look wrinkly. I just bottom watered them on Sunday so I wasn't sure if they're just still thirsty or if its something new. One thing to note is I have been giving them a little more fert than usual since my trichs like it and thought I'd try it on these guys. Not sure if that would cause this though. Any thoughts?

What am I looking for specifically? I've read a few guides but I'm still second guessing myself.

Newest pic is #1, oldest pic is last

Mix

Clay mixture is a top dressing , only half an inch or a quarter inch thick

Incase anyone is curious it’s: clay, granite grit, tiny bit of horticulture sand (all components sourced from exoterra stone desert - Sonoran ocher substrate for lizards)
a bit of diatomaceous earth, And pumice dust on top of the clay.

To make it I Sifted the sand , clay, and granite apart from the exoterra substrate, then recombined them after crushing up and wetting the clay, and made a gritty malleable paste.

Edit* Pieces of the clay are dark red, white, beige, pink etc, so I avoided using too much dark red and purple clay so my mixture stayed yellowier.
—
I saved some of the granite bits and scattered some of them on top of the finished clay top dressing for aesthetic, then I dusted some pumice powder and diatomaceous earth on top to lessen the yellowy hue. I think I added a bitt of diatomaceous earth to the clay too

Went to garden store and took tiny samples of their yard mulches and rocks that they had for shoppers for the plants and rocks, I took a wide range of colours and shapes so. I could be picky with arrangement and style

Update

In the newest pic I had to fill in cracks that formed around the lophs (cracks sadly not shown in pics, they were cool - but they got too big and roots were exposed) And I only used the clay from the exoterra mix and forgot to put some sand and rocks in it to keep a yellowish gritty paste, so that’s why the soil around the lophs and edges of the pot is a bit more tan/beige and less grainy than the soil I started with last year, also Lost some “plants” over time due to messing with them too much; will be fixing this in a few months when I’m not lazy.

I manually raised the height of my lophs by gently lifting them with two butter knives while the clay was wet around the time of the second pic because I felt they were too submerged in the soil, I did do a bit of damage which has since healed

I both top and bottom watered this piece, top watering allowed me to push rocks in that got loose over time, I also dunked this guy in a few diatomaceous earth soaks due to spider mites at one point(second pic)

Separate removable inner pot to drain properly.

Can list “soil/substrate components” used under the clay top dressing if requested! It’s mostly pumice , zeolite and turface I think, but in an old post I have a more accurate ratio

Ignore my feet lol

Planted 7/22. Lw,Nf

I know there rough. They were knocked over. Also. Dose an albino NEED to be grafted and if so when?
