Yeah, especially seeing as how it was in bloom in June, I'm not expecting much from it next year. And I've heard that cybisters often don't rebloom regularly anyway. OTOH, it's an impressively fat bulb, so We Shall See.
And no, I don't plan on separating those bulblets at all. I like the clump effect. I'll just move the whole clump to a bigger pot when it gets too crowded.
Incidentally -- I never had much success with amaryllis until I started using clay azalea pots, the type with extra drainage holes as you might use for orchids. Now I'm a real convert -- that's all I use for them.
