Stuff (moss, green slime, liverworts) grow where there are nutrients so 
watering fertilizer on the top of pots encourages this. I also feel that 
often the bulbs are near the top of the pot and appreciate being kept 

So if I have time I like standing pots in a tray of water (watering from 
the bottom). The snag with this is to keep the water clean, or else one 
transfers disease from one pot to the next.

Another option I've seen described for seedlings, and tried (but with no 
results to report) are slow release granules, one can control the 
quantities easily and precisely - although probably not the speed/timing 
of release.
