Haemanthus growth cycles?

In Holland they are very good at that.  The bulbs are planted in the spring,
lifted the end of the summer and put in warm storage (to simulate the summer
dormancy) These bulbs are offered for sale in the spring. The species
concerned are Moraeas, Tritonia, Sparaxis, but I suppose that this procedure
may also apply to Haemanthus coccineus. For this experiment you better buy
bulbs grown in th southern hemisphere.
Bonne chance
