Not true. I have a pot of about 10 aloe of varying sizes that started as one offset. The original (Mom-
plant) is still the largest and
growing strongly. The first offsets are offsetting, and I have no intention of splitting up this group. This is the way they live in nature, in large colonies. If you want to pot up a baby or two separately, just pull them gently from as low as you can. They'll break off, maybe with a root or two already if they were largish babies. Let them dry out in the shade for 2 or 3 days to heal over the break, then pot and grow as normal; a fast draining soil, not too much water, and plenty of direct sun light. Sounds like yours is happy. Good going!
