Cyrtanthus seedling problem

Hi Leo and Rob,

Oh, if we just lived in Tasmania, or even New Zealand!

I use a combination of these two methods.  I float Cyrtanthus seeds on 
water until they just barely start to sprout a root.  Then I stick the 
sprouting seeds, root-down, into a layer of sand about 1/2 inch deep on the 
surface to the potting mix in my growing container.  I get at least some 
survival this way.

They do require pampering -- cover the container loosely with a sheet of 
plastic or a too-large plastic bag.  I set the container in a saucer and 
keep some water in the saucer until there is good leaf growth.  Then start 
to uncover very gradually, and let it dry a bit in between waterings.

Like Leo, I used to try straight floatation, and also got 100% 
mortality.  With the sand, I get some survival.  Planting straight into 
potting mix has never given me any germination in Cyrtanthus.

In summer, it is far too hot outdoors most of the time for these young 
seedlings to get started.  Indoor in winter, under lights, it is too dry.
