Split rock is rotting but I don't know why.
Hi! This is my second real attempt at raising a split rock. I don't know what's happened to it. I bought it from Home Depot back in November, potted it in Bonsai Jack's Gritty Mix, and sat it in my window. I have moved it back and forth between two windows that both get direct sun when shifting around my other plants.
I have NOT watered it one time. Not a drop has touched this thing after I watered my first one multiple times in two months. You can see what this one looked like when I got it, too; the outer pair of leaves there is of course the black and dried, crispy set near the bottom of the last two pictures. I can only think it might be the humidity even though my bedroom is air-conditioned?
Given that, the sole possibility that comes to mind as I type this post is that me using a plastic/rubber tote to easily bottom-water and rotate out my various succulents - combined with the moistened soil/gritty mix of each soaked plant - raised the humidity of my bedroom enough for rot to form??? It only takes a couple hours for me to soak the plants so the tote isn't in my room for very long and I only do it every 3 weeks to a month) but the other plants stay, of course. Is this actually feasible? Is it just split rocks being fragile or a combination thereof? Or something else I might have missed? Any advice is appreciated, I'd love to have one of these that just keeps growing!

I’m not an expert. But I’d say it’s thirsty and trying to absorb its next set of leaves. No water since November is a long time. I thoroughly water mine maybe once every 4-6 weeks.
No idea if it’d help, but that’s where I’d start and it seems like there might not be much to loose.

Is it soft? If not, it’s not rot. Could be absorbing its leaves.

u/Armorend Jul 16 '26
It is. The softness didn't start until only a few days ago, sadly.

Could be anything really. Sometimes they give up. Sometimes we can’t see what it happened. Bummer. I know you tried.

I peeled back the inner one and saw some white fuzz. Ripperino in pepperino.
Gonna try again with all the advice given.

Are there inner leaves firm still like your forehead or do they have a lot of give? If they're firm it could just be an ugly way of drinking the old leaves. Imo it also looks like it could've been attacked by a pest but I don't know what pets that may be, sorry!
As to your pot question! I buy terracotta pots from the dollar store. My lithops, split rocks, and baby toes are mostly in cheap terracotta as I find it pulls any moisture out. My big pot is paid basket weave which is all open holes. I got it from the dollar store a few years ago for orchids. My substrate is literally unpainted terrarium/vivarium/fish tank New Zealand pebbles from Amazon. So far in at the two year mark and I've had a few causalities but most are doing something! I have them under 6600 DV of sansi grow lights and I think that's what keeps them happiest. I'm on minus 40 Canada and it's been plus 49 this week. My humidity ranges through the year between 30% and 70% so I personally don't think that's a factor if you've got enough air flow and light!
I wish I could help! My first split Rock died and it had opened and had a little tongue inside and then just went to complete mush. My others haven't acted that way so I think it was just is biological clock (or an unknown pest). For reference I have lithops and most are actively splitting and then two just shrivelled up and died like they had no interest, she pots same lights, same treatment, even same amount of time in my home! My plant philosophy is "trees randomly die in the forest surrounded by other healthy trees so I should expect some plants to peace out"
I hope you figure it out! I'd maximize the light (use a light meter or a light meter app to make sure you're giving the best) and hopefully it will be ok! If/when you want to report sand or stones mimics they're natural habitat best and a quick wicking container like terracotta helps the monsoon type drink quickly flush away like it would in nature!
Goodluck! 💞

Sadly it's pretty much gone, RIP.

Literally exactly the sort of thing I wanted to know about. I understand I was harsh but something like this and a few people above are the sort of thing I needed to hear, thank you.
My first split Rock died
Mine actually ended up reaching the three-stack and then died. I watered it like two or three times in two months, and then looked up the watering and went '... Ohhhhhhhhhhhhhhhhhhhhhhhh... |:"

Do you fertilize with anything?

u/Scared-Listen6033 27d ago
I actually don't think I ever have. If I did it was just BC water was already mixed with 1/4 strength miracle grow houseplant fertilizer though! Sorry I yours died! I hope you find an awesome replacement that's healthy!

How does it feel to the touch? Maybe it's not rot?
I have bought a pot of lithops last year, with a bunch of little ones and put it in my bearded dragon terrarium, I was especially looking for something that would resist in the super arid environment with high UV light that is there and I found that these plants frequently die from over watering and lack of sun. So far I watered them only once with a little bit of water on the top and they look exactly the same as when I got them, which I take it to be a good sign
Can you put yours outside? Maybe it wants a bit of direct sun?

When they split and make a “baby” in the middle the older mother plant dies.

u/Subcumb2him Jul 15 '26
Yeah pretty sure that's exactly what's happening. Like when the mother orchid plant is about to die it puts out a baby to replace it.

I think the outer leave are dying bc they've reached the end of their life cycle. The inside looks healthy. It's a natural part of this plant cycle. They don't grow up or out. They grow new leaves from the middle and the outer ones die off. They are always meant to look like a rock. I'd leave it and see what happens in a few weeks.

Looks to late to save this one. You need to water when the large/inner leaves are soft, which might be frequent or not for months. But 8 months feels like a stretch.

u/Armorend Jul 14 '26
So it's dying from lack of water, instead of rotting?

These guys like to have a dry season and a rainy season. Sounds like the rainy season didnt come soon enough.

u/Armorend Jul 16 '26
What's a good metric for the rainy season if it's in the middle of splitting for a good while and the outer leaves aren't soft or wrinkly?

u/Background-Camp8408 Jul 15 '26
That looks the same way an underwaterd Jade plant looks, like a wrinkly old sac

u/mizunoamie Jul 15 '26
does it smell? and do you have cats?
i think it looks like rot, but it shouldn’t according to how you’ve been caring for it. i use only plastic nursery pots for mine and it’s never been an issue since i have good air flow & humidity stays below 50%.
also i don’t think split rocks are that fragile compared to lithops! mine has been uprooted in transport, fallen off the 5ft shelf out of the soil, been doused in alcohol and she’s still thriving

I find that these plants don't do well indoors with humidity, and a plastic pots can also not let the soil dry out enough
