Both are echeveria perle von nunberg. Likely under different stress and exposure to have different collor//

Its an echeveria. They arent in need of mineral soil.... Its one of those plants that can do well in just about anything, except muck, if watered properly.

Interesting that you say this Stefan. I've about concluded myself that they might need a more organic mix than most succulents. They seem to do better with more water than most. I'm trying some in nearly straight potting soil with just a bit of perlite to see how they do.

Ive never grown my echeverias successfully(save for the infested one) in anything other than plain coir/peat soil....

Most did pretty well. Dudleya,sedum and graptopetalum too...

Similar soil makeup for aloe(aceae) and others

Mineral , i save it for cacti, euphorbia and stapeliads. Maybe some tweaked variant for mesembs too...

Stefan, what species of Stapeliads are you growing? Have you ever smelled a real, live Brachystelma barberae?

Huernia(something), stapelia(no id) orbeas varigatea and decaisneana , ceropegia sandersonii and woodii . Germinating a fockea(and failing).

No, but im doubtful it can beat "vinegar made from cow dung" at biogas plant .

Its like a knife going through your nose, into your brain.

Haven't smelled neither. Not a liana fockea I hope. Where would you keep it? I want a Frerea indica!

Fockea edulis. its a caudiciform, and even if it is, its probably more manageable than ceropegia sandesonii.

Do you grow yours under lights? I don't grow any Stapeliads because I don't have bright enough lights, but I'd live to grow most of them except the life savers lol. I figured it was a cadiciform. What's the problem with the germination?

Good luck with your Echeverias Jemima!

Never tried germinating anything outside fockea, the problem is bad luck and probably my own incompetence. Dont have grow lights(im in SE europe), never tried. They get enough natural light though...

Southern Europe, lucky you. I was thinking you were in Scandinavia for some reason?

Im only one zone hotter than you though... Still and indoor grower for half the year. Anything outside semps, hardy sedums and opuntia humifusa. Trying out delosperma and lewisia, will see how it works out.

I've grown that Opuntia for years. Taking out those microscopic thorns with tweezers. I was just thinking I could get a couple Stapelias, because I'm already growing some other tropical Asclepiads that I might start overwintering under lights. There are Calotropis, Dregea, Tweedia. Trying to pick just 2 species. That would be hard!

I saw the first one on one of those bear grylls shows. Apple of sodom....

I grow cacti/succulents so cant really help you with that. Those are not in the category, and are pretty Maybe try broader apocynaceae with hoya, adenium , pachypodium or plumeria or something. I grew plumeria and adenium from seed with better success.

Noted your above comment on the ripe smells of a biogas plant. A farmer near me has a small biogas plant to power most of his large dairy farm. When he spreads the compost residue on the fields, it is truly awesome . One has to practically stop breathing or gag reflex takes over as you drive past.

Be careful of spraying recently taken cuttings. If you keep them wet, they could rot instead of root. Spraying every day is too often - I actually do not believe in spraying plants or cuttings, but that is JMO. It is OK if it is warm, good air circulation, and not so often, and plants are thirsty (usualy, the leaves start shrivelling). Feed of any kind may be too early too. How long ago did you pot them up?

Just in case you are not aware, these plants have fine powdery coating on their leaves, often referred to as farina. It should not be rubbed or wiped off. Sometimes it is unavoidable to get some off - on some plants, it rubs off very easy - but try handling plants by the leaves as little as possible.

There is a good saying/mantra to remember: no roots, no water...

If plant doesn't have roots and is watered, it often starts rotting. Have a look at [THIS THREAD[(https://www.houzz.com/discussions/beheading-plants-dsvw-vd~4611851?n=119) that shows many different plants being beheaded - I am sure there are pics of your plant there too. (thread continues, link to #2 is at the end).

Succulents are arid plants, and even mature plant with roots should not be watered every day. How often? - that depends on potting mix, temps and type of plant.
