Pollination of Haemanthus

All my bulbs are single bulbs/clones, grown from seeds some years ago 
sent to me. About half have flowered for a few years now but not clumped 
so far. Maybe not feeding them enough and lack of space / and too small 
pots. I have moved some into larger tall form pots this year.

I am not sure if Haemanthus will self pollinate, but if I recall 
correctly
I have had single clones produce seed. If you have two plants flowering 
at
the same time you can rub your hand from the top of one then the other 
back
and forth a few times. Individual flowers of a head will become 
receptive
at different times so for best effect you do it over a few days. I find 
a
flower on the head usually produces fluffy receptive pollen and then the
stigma and style elongates after to rise above the pollen sacs becoming
receptive.
When I want to cross two particular clones and minimize self 
pollination, I
will remove the anthers as they ripen with tweezers, storing them in
gelatin capsules in a container with silica gel in the frig for later 
use.
When the stigmas and styles become receptive I will use one end of the
capsule holding the anthers to transfer pollen. Using this method I am
currently crossing Haemanthus humilis humilis 'Giant' that was the first 
to
flower this season on Haemanthus albiflos that is just starting its 
flower
period.
All the best, Michael

Hi
How do you pollinate Haemanthus coccineus "by hand" ? Some plants, eg.
Sciila madierensis (flowering alongside) I can more or less just bang
their heads together, or the bees, if there are any still around, do it
for me. Haemanthus want a bit more care. No humming birds here in the
UK. The long hot summer has ended and the lawn is going green again.
Looks as I am too late this year as the stems on 3 different plants are
beginning to curl over, but next year ?? I have H. albiflos too but not
tried with them.
