I'll tell you honestly that before this Frithia not only survived, but also bloomed, several of them did not survive with me ...
Finally, I understood the reason, and the reason was that, unlike other "living stones" Frithia does not tolerate overdrying well.
And I watered it very little, that is, just like the lithops ...
Result: several Frithias died ...
Therefore, in the summer it needs to be watered regularly, but not abundantly!
Frithia needs to be kept almost dry in winter.
Small pebbles should be added to the soil for succulents.
Plant only the root system in the substrate, and cover the root collar and the lower part of the Fritia leaves with pebbles.
