Initially there were three plants in each of these two pots but then this spontaneous regeneration happened and the plants started squeezing and pushing each other. I've moved the smaller ones to a separate pot (with some other Lithops of course, there's no room to spare!) to let the remaining plants grow nicely. It's pretty strange that they've almost digested this year's leaves already. I'm not watering them but will probably do that after they're done. Still, winter is coming and what do I do then? If I water them normally I already see them turning into cucumbers. I guess I'll cross that bridge when I come to it.
Oh well, at least these troublemakers look pretty. :)
