My stone face succulent is shriveling up…. WHY?????!!!!!!!
Judging from the way your succulents are leaning, I am going to go out on a limb and suggest that these aren’t getting enough light.
All of the pebble plants (Lithops, Conophytum and Ophtalmus and related types) all have weird dormancy requirements, as well as being extremely sensitive to wet soil.
They absolutely have to have well-drained soil and very little water.
I water mine about twice a year, whether they need it or not. Watering more than what they want at any particular time will cause root rot and instant death.
These are not a succulent plant for beginners, and in addition, they must be grown separately from other plants, because of their pickiness.
If you want to give it a chance at life, you’ll have to take it out of the mixed planter and have it in a separate pot and keep it in a brighter area, and stop watering it for at least 4 or 5 months.
Where they are native, this would be in extremely bright deserts, with intense sun. They may struggle along for a while in poor conditions, but eventually just shrivel to nothing. Don’t let this happen to your plant!
Best of luck with it,
