I just picked up these new babies on impulse at the 99cent store (of all places!), and I think they're great! I love succulents and I was pleasantly surprised to see them in the store. Do I need to repot them or are they fine in those tiny pots for a while? How will I know when to repot? Also, do I need to detach those little baby rosettes on the left plant and pot them in their own pots or should I just leave them alone?
