I was scared to give them water because of what everyone says about lithops lol. I was freaking out yesterday when nobody responded so I gave them some water and they look pretty much the same. I also moved them out of the direct light in the window, and put them on a table in the same bright room

At the moment they are in a 50/50 blend of perlite and cactus/succulent soil. I did buy a bag of volcanic pumice I found today at the hardware store today, but I'm really waiting for a specific soil blended for lithops I purchased online.

I noticed one of the smaller ones is beginning to rot. I don't think lithops are my thing ..I've never killed a plant so fast.

If it's rotting, it's certainly not your fault--it would have started earlier. It doesn't look like rot, but it's hard to tell from a photo or know what's going on inside or underneath. Did the roots look relatively long and healthy when you first repotted them? If they were mine I certainly would have watered them even though their dormant period is coming up. Normally a full watering would be done after splitting in the spring or early summer, then maybe a couple of or some sips before dormancy when it gets hot, then nothing for a while until sometime in the fall.

It's difficult when we don't know what conditions they were grown in and what the particular timetable was for these plants as far as when they split. I have one that still has the old leaves on it and isn't even finished with that yet.

Thank you so much for all the helpful information. I really appreciate it. I'm definitely going to check on the roots later this week when I get the new soil. Until then I won't disturb them.

So true about not really knowing what conditions these plants were grown in. I got all but one(potted) from a nursery on Etsy in Southern California. The smallest one came (unpotted) was a gift with seeds from another Etsy seller, and is approximately 5-7months old so I don't think it would have split yet.

All the roots seemed relatively healthy when unpotting them, and they had already split because the old leaves flaked right off. However, I'm pretty sure the one that looks like it is having a rot problem came with significantly shorter roots than all others.

Unfortunately, I already ordered more in the mail from the same seller because I'm impulsive. Maybe I won't unpot them for awhile and see how they do.

Lithops normally split at about 4-6 months. I have some seedlings that were right on time. I was surprised how early that happened. I had forgotten they do that so quickly.

Hopefully the problem plant will recover if it hasn't rotted and the other ones will be fine.

I bought one that I didn't repot for a few weeks or months (I don't know why) and the roots became very unhealthy and short after sitting in pretty caked peat moss, unless they were already that way. They were able to recover after repotting in mostly pumice with some potting soil and giving them sips now and then.

Wow I had no idea they split that early! I figured they were too immature. I started some seedlings a month ago, and the lithops are so tiny. Hoping not to kill them.

Glad your lithops were able to recover from that! When I received mine I felt like they looked too crowded, and thats what made me repot them. May try to experiment and pot some in mostly pumice & a little soil, and some in the new lithop soil and see what happens.

Cant wait to check the roots and repot them into better soil later this week. Thanks again for responding to my post! I just joined and I figured no one would so it made my day :)

Lithops aren't one of the more popular plants here, although there are plenty of people here who grow them that are much more experienced than me. I hope you can still get a second opinion. Growing from seed is a great way to get to know them.

I spoke with the seller and he told me they just look thirsty. He recommended soaking the soil all the way through, and they should plump up within a couple days He said waiting for them to wrinkle is a fool proof way to avoid overwatering.

That's good you contacted him. If you'd like, let us know how they fare.

Curiosity got the best of me and I dug up one of the pots to see how the roots were doing. To my surprise they are actually growing little white roots.

The one that I think has something going on with it has new growth too. Is it possible that it came to me overwatered and the mark on it is where it split?

When it splits, the whole things comes off. The only indication would be the old leaves. The roots are certainly a good sign. After thinking about it, I remembered that the one I mentioned that had the sickly roots also looked kind of wrinkly for quite a while. I don't know why other than if they don't have healthy roots, they might not be able to take in enough water. Yours look like they should be able to. I would carry on and not worry about the wrinkles.

*Update*

Thanks Jeff! You were right they just needed water. The lithops have finally filled out a week after a good watering. I just wanted to update this with a pic for anyone who comes across it in the future.

Whew. Thanks for the update. I was hoping you'd get more opinions. It's rather nerve-wracking giving advice on them, but you hadn't gotten a reply, so I wanted to try to help. They look great.
