I use organic fertilisers Anders. Seasol (seaweed solution), Megafol (organo-mineral liquid, smells like Marmite) and Nitrosol (liquid blood and bone). I alternate these to whichever I fancy. And DON'T USE these at full strength. Feed whenever you water, and they do like water when in growth to keep them moist. Mine also got some rain on them.

I saw the plant this spring. The bulb had grown quite big and is sure that it will flower in a year or two.You could be right about we not feed the bulbs enough though. What kind of fertiliser are you using - the same as for orchids, or?
