I recently got a family member into succulents. We picked up these living stones yesterday, along with a sedeveria. The three on the bottom are mine. I’m planning to repot all of these in mostly pumice, in 4.5 inch terracotta pots. Can I pot all three of my lithops in one pot or should I keep them separate? I was hoping to conserve space since I have limited spots left on my succulent shelf under the grow lights but if I have to keep them separate, I will.

Thanks!!
