Fierycloud and Jim,

Just to follow on with this from our experience here..... the old 
established clumps that do best of Nerine bowdenii here tend to have 
the bulbs sitting at or on the surface, forced there by the 
overcrowding of the clump.  This means that they do tend to lose the 
insulation factor of the soil temps below ground.  When we're getting 
our temps up to 40'C in the middle of summer we rarely get below 18'C 
at night (and then only briefly before dawn), and for some periods we 
can be 20 to 25'C at night for quite some time.  I'm mentioning this 
to act as extra information for Jim to use when working out for his 
conditions.  Certainly we don't get cold nights to 10'C in the middle 
of our summer (oh but it would be SO nice <grin>), unless we get a 
cold front move through briefly.  I would be expecting the surface 
soil temperature to probably be higher than the air temperature as 
well.  Jim, take heart!!
