Was your summer too hot or wet maybe? Maybe they are still dormant? My big Haworthia has finally woken up this past week with a long flower. Summer was WAY to hot for it and it looks a bit rough because of it. But I think its recovered and is awake. Hopefully your Lithops too are ready to wake up soon.Glad to read! Sounds like a thriving cactus!
Yeah, I don't know what it is. This past year was very hard on them. Summer is typically an escape from the rainy winter months, but this summer was brutal. Totally threw them off. Even my oldest, hardiest lithops look pretty rough. I only have two that look OK. One that flowered and is expected to split soon, and one that has yet to flower. Odd, odd year. I hope our lithops pull through
