Oh MY!!
WRT blooming, ours on;y bloom ~ every 5 = 7 years. Just one of 3 pots bloomed this past summer.
We did not not do one of ours that REALLY needs to be done. In a large clay container that my DW does NOT want harmed. If it were up to me, I would just break it with a hammer. She is adament about not harming it as it is ancient and has sentimental value.
Unfortunately that is the one that most needed dividing.
