I know this is late.
Well - one thing I would add. I usually dust my bulbs, corms, rhizomes et cetera that I store with powdered Sulphur. Can help to ward off fungus. I usually store everything in Perlite or vermiculite. Then following season use it in soil I am mixing to use in the ground.
I am thinking of growing some Watsonia Aletroides next year. So beautiful.
@gemini_sage - you could try in containers - that is what I will do if I get some.
