Hi, fellow Marylander here.
I have gotten some bloom, most years on my Clivia. I keep them out late into fall, move them into downstairs coolest corner for winter.
Will, thanks for the notes, I will try to move them under an eave so they start being drier as weather cools.
Yours looks great, (though the trowel stuck in there makes me cringe- roots ouch). Mine is potted mostly bark and has exposed surface roots which it does not mind.
