Is this something that should be done?Is there an advantage?

claritamaria,

From what I understand of their life cycle, they produce large clumps up to 3 1/2 inches across, keep growing for a year or two that way, then start to decline. Reinvigorating the clump means breaking it up and separating all the plants out so they respond by regrowing. Each plant should start making its own little clump and the die back from the old clump is halted. It seems that after a while a clump will build up too much dead matter and just need to be repotted and divided. It should be done only when you notice too many plants browning, not producing much dew inexplicably, and looking listless regardless of how much water and light they get.

After several days, they are all still alive and growing.

Even this tiny plantlet, barely half and inch across, is opening new leaves and showing some red coloring now that it can get some light.

Not to hijack... Here's an example of just what you were talking about... from 2004. The six pots to the left are from the original clump, purchased the previous summer:

And then you can give them away!

Thanks petiolaris,

Exactly!
