Hi Doc,
The hang downers are a pain to successfully repot. The hangover growth gets fixed in that downward position and the slightest upward pressure makes them pop right off
...which in turn causes one to swear.

You'll still wind up with a good sized plant if you remove and plant the hangdowners and then replant the momma plant too. It might be wise to go to a 3" or 4" larger pot for the main (momma) plant. It doesn't take a large established Catt. any time at all fill in that amount of space. Let us know what you decide and don't forget to post pics. Woops, I almost forgot to ask. When does the big one usually bloom?
