I think you're right! They look exactly like Sedum Lineare! Thanks!

anyone?

i'm no good with ids, but I think E is some kind of jade . . . i won't go more specific than that because i'm usually wrong, lol.

i'm not familiar with the climate in singapore, but if it's humid, i'd think you'd be better off with a mix with less organic matter (ie soil) and more "grit"-- stuff like perlite, pumice, gravel, etc, so it doesn't stay too moist for too long . . . i'd start by cutting it with half perlite, but if you want, you can try searching "grit" or "gritty" on this forum; you'll find a lot of people discussing various soil mixes for various climates and i'm sure you can find someone in a situation similar to yours. a lot of people in central/eastern US use the "gritty mix," which is 1-1-1 turface, pine bark, and gravel . . . i'm not sure how well it will work for you since it seems to be good for cooler/drier climates, but it might be a good place to start until you figure out what works for your plants/your climate? idk, just throwing out ideas c:

re: watering, i water when the leaves on my succulents begin to lose their turgidity, which ranges from three weeks to, like, a few days for my one super-thirsty jade. for me, it was mostly trial and error until i got into an okay watering schedule (well, it's still trial and error, but at least i'm doing better than i was before!)

Search Al's gritty mix on this forum. While Im sure the cactus and succulent mixed with 50% perlite will be better than what theyre in, you said you live where its hot and humid, Als gritty mix should be better for them but adding pumice to the cactus soil would be better than the perlite. Hope this helps. :)

Thank you! I did read up on Als Gritty Mix, but I haven't been able to find it in nurseries so far, perhaps we don't have it here. I'm trying to find the individual components and mix it myself.

What size gravel should I be looking for?

Unrelated question, any idea if D can be propagated using the leaves? I haven't had any success so far, I let it scab and then the leaf just shrivels up or turns black

it's not a premade mix you can buy (i mean, there are people selling it on ebay&etc, but it's not official/trustworthy). there's lots of info on sizing in the posts on it c:

E is definitely jade. It looks like Crassula ovata 'Crosby's Compact' to me. Make sure this plant gets plenty of light or it will get really leggy and fall over as it grows.

K are some types of Aeoniums.

J is an Echeveria maybe? I am not too familiar with these plants.

I appears to be Sempervivums.

I am not familiar with what D is, but to answer your question about it, it looks like one that would propagate better by cuttings.

Okay, I understand that I need turface, pine bark and crushed granite in roughly 2-4mm size.

Is pumice a substitute for granite?

Where would perlite fit in?

What can I substitute turface with if I can't find it? Cactus soil?

If you are following the Al's gritty mix recipe for the science behind it, pumice will not substitute for granite and it would not require perlite. Turface can be substituted for DE or something called NAPA floor dry (something that I am doubtful is available in Singapore). You can search on here for substitutes, especially those available to you there. If you are however just looking for a good mix for your plants, you can use any combination of those ingredients you mentioned.

H might be a ghost plant. It looks like my small ghost plants started from fallen leaves.

Turface is proving to be tough to find, NAPA floor dry too. The only DE I can find are the ones in powder form.

Currently I have perlite, pine bark, 2-4mm wide pebbles.

Any thoughts on these? Especially with regards to what I have and in the absence of the elusive turface?

-coconut coir (been reading mixed reviews. would it work with the other stuff i have?)

-LECA balls, light expanded clay aggregate, smallest available are around 4-8mm. Seems too large

-volcanic sand?

-pumice?

Should I go ahead and repot? Getting nervous about these guys sitting in clayey soil. Or should I continue my search for Turface and they can wait a while more?

I'm not sure what LECA balls are, but you have to be careful with clay products. Turface is specifically designed to not break down when it gets consistently wet because it is fired at such a high temperature.

I think the coconut coir retainscway more moisture than is appropriate for succulents.

You way want to make a mix with things like granite, pumice, perlite, and bark and use the pebbles as a top layer. Make sure you was off the bark fines first.

LECA description. Is 1200 degrees celsius considered high? Apparently doesn't break down too.

Manufacturing Process - LECA is made by baking pure natural clay at 1200 degrees Celsius for 3 hours in rotary kilns; the end product is pH neutral, doesn't degrade and is autoclavable. Capillary action on the surface of the lightweight pebbles allows it to absorb 40% of its weight in water and also allows for efficient evaporation to help maintain a constant humidity level. LECA is manufactured exclusively in high-tech kilns in Germany, Denmark, Australia and China.

Physical Properties - this versatile medium has hundreds of tiny pores that retain moisture. Large 8 to 16 mm average diameter size allows for maximum oxygen to the roots while providing a stable base for plant roots grown in active hydroponic systems or passive hydro culture applications. It holds water extremely well and transmits it effectively to the plant roots. The pellets are uniform in size and have an attractive, natural appearance.

I would definitely say that would be great for a potting mix then. Just make sure you sift finer particles out. If you don't have a sieve you can rise them as well.

Wonderful! Do you think it's a substitute for turface? Can I do 1:1:1 with LECA balls, granite chips and pine bark?

Do I still need perlite?

Erica
LECA is Light Expanded Clay Aggregate.
It has many uses, regarding plants it is used a lot in hydroponics. It is very light, doesn't decay like soil, freezing/melting and fire resistant, insulative (sp), improves drainage, hp about 7, retains water...and some more.
It comes in few sizes.

Thanks Rina. I've never heard of it but I've never done hydroponic growing before.

I would say if you can't find Turface that is a good substitute. You don't really need perlite for that mix, I would use it more if I were mixing it with a store bought cactus and succulent mix.

Erica
You got more posts about it - looks like we were all typing at the same time...

I don't have personal experience with it, just read about. Few people even grew succulents in it in semi-hydro (here is one of the threads from MsGreenFinger: semi-hydro. I believe there are others?).

Rina

I have read about some people using semi-hydro for succulents but it never really interested me all that much. Perhaps that is because the concept to me is very strange. I am curious now as to how her plants did over the winter...

I found several posts on people using just LECA balls as a growing medium, without mixing anything in.

What would be the benefits to adding crushed granite and pine bark to it?

I just looked up pictures of LECA balls. Choosing your growing medium is essentially a personal preference. You can add whatever you like to a mix that suits how you care for your plants and how you want them to look aestetically. It looks to might a lot like what people use for semi-hydro growing like what Rina mentioned earlier. As I said I am not familiar with the product. I can't give you an exact specification for how to make your mix unless you are using the ingredients to Al's gritty mix, because that is what I use.

I think your best option for where you live is to indepentendly research the ingredients you are able to find and determine that way what you want to put in It. The suggestions everyone gave you is a good place to start. I am not sure of your climate but if It is more humid, you may want to stay away from materials that hold more moisture than others. They key to a good mix for succulents is a loose, fast draining medium that allows the plant to obtain water while not sitting in it.

savemysucculents,

Humidity in Singapore is not to be trifled with--we're not talking about pithy 50 percent or even 60 percent. For most of the year, the air will have moisture of over 80 percent, going closer to 100 percent during the monsoon, even with the heat. So I think your idea of getting a grittier, airier mix is a good one.
Assuming you are raising these succulents outdoors (balcony or your yard, if you have one there), what I suggest you use for substrate is crushed pumice (readily available in KL nurseries, I'm not sure about Singapore) and crushed coconut shell with the powdery bits sifted out. The gritty mix is all about the rough similarity in the size of the particulates, and only secondarily about the actual components. The particulate size most often suggested is about half a centimeter and definitely remove the fine bits. You will do well with just these two ingredients, tweaking the proportions as you learn both about your watering habits and how the plants adapt to it.
If you are okay to spend more, you can substitute akadama for turface. But if you can find pumice there so close to the Pacific Ring of Fire, I wouldn't even bother. In point of fact, you will do fine with nothing else but crushed pumice, provided you fertilize them.
I am sure a lot of people have succeeded growing succulents in LECA balls but it is a skill set that is just too esoteric and involved for my lazy bottom.
Finally, keep these kids out of the monsoon.
Nice collection, by the way, though that sempervivum makes me nervous (i). They are alpine plants that do not handle humidity well. They probably survived Ikea because the air conditioning kept the air dry.

I hope this helps.

It does sound that if theses guesser outside, one should not need to water at all
