how many plants per pot

At the NARGS winter study meeting in his lecture Ian Young advocated 
planting bulbs quite thickly, saying they love company. He showed pictures 
of I think it was Crocus and Narcissus that were planted almost touching in 
the pot.

This leads me to ask the question about which genera or species like to be 
crowded and which do not. Sometimes when I repot the plants are so crowded, 
I can't imagine how they all fit in the pot and how there can be enough 
nutrients or soil to sustain so many plants. I'd always heard that when 
they stop blooming it may be time to divide. And it would seem to me that 
if some species were planted too densely there could be a problem with 
disease for those of us who live in areas with excessive humidity over a 
long period. With Massonia and some Haemanthus with long leaves that are 
prostrate, the leaves of some of the plants sometimes get covered over with 
leaves of some of the others and then it is difficult for the blooms to show.

When plants don't bloom for  me very regularly when they seem large enough 
to bloom (eg. Eucomis) could there be too few or too many in a pot?

Yesterday I tackled a pot of Nerine masoniorum which hadn't bloomed for a 
couple of years. Since it is almost evergreen I haven't repotted it. I 
intended to divide it to send extras to the BX, but have been having wrist 
problems so needed to let it dry out a bit to do it and then got swamped 
converting the wiki. This was a 8 in (20 cm) pot. The bulbs were really 
dense. I counted them and there were 254 bulbs in that pot. I mailed most 
of them to the BX this morning. I don't believe the soil in my garden is 
wet enough in summer to support them in the ground and I'm trying to reduce 
the number of pots I have.
