All the repotting I did the other day ended me up with one large plastic pot empty again. So I took the poor Mum, which is still bravely flowering (although it hasn't straightened out at all) and shifted its quarters. Good thing, as the pink ceramic pot it was in (zero drainage) was causing rot. It's still in a too-small pot but that's better than rotting. I'm going to smash that pink pot and use it for shards, so I don't put any other plants in there to suffer.
