More semi hydroponic questions

[Diane56Victor]

I have over 100 clivia, live in Australia and have never had to artificially chill the clivia I grow.
My plants have been sourced from South Africa as seeds, locally as seed, seedling and mature plants. I also have the different types of clivia, gardenii, nobilis, robusta, mirabilis as well as miniata and Interspecifics.
All these plants grew well on the Adelaide plains area (very hot and dry in summer) with temps in the high 40C for weeks on end sometimes and winter temp averaging 4C to 10C

When we moved to the coast an hour south of Adelaide where the temps are much more temperate 6C to 28C the clivia never missed a beat despite being ignored, and probably mistreated while we built the house.
The cool period they get naturally here is enough to make them bloom. They are under shadecloth all year, I dont water them in winter at all, they survive on what gets through the shadecloth
Over Christmas I had 2 interspecifics in bloom.

Edited to include. Its generally accepted, at least within the group of clivia growers I know of that flowering is triggered by a lowering of temperatures but no one I know refrigerates them, all the growers I know of in Australia grow under shadecloth.

A last word on this post. I noticed tonight my clivia (which Estasion Seca helped me save) is pushing a bloom spike. It sits by the north facing patio door, by a heat register. Clearly not needing a chill. I nearly lost this plant a few years ago when my greenhouse froze.
