If you have just bought the bulbs and planted them earlier in the year then the problem is with the bulb. They should flower beautifully the first year. You need to start feeding them with half strength tomato feed now and hope for better results next year.

Excessive fertilizing/feeding can promote disease and soft growth.

High potash feed shouldn't produce soft growth though?

What size (diameter in cm) were the bulbs? Some companies advertise "Premium Grade #1 Bulbs!", and then deliver runts or younglings.

Thanks for all these comments.
I think the bulbs were premium size-from de Jager quite a reputable company and they have agreed to replace them. I do think that it was my 'fault' though!

Bulbaholic-will start feeding them but not sure whether to put them in the ground or leave in the pot. ?

Either, Sparkly, whatever you fancy. Whichever you choose, leave them in the pot until the foliage has completely died away and then let the pot of compost dry off for a while. Empty the bulbs out and replant in new compost in a pot or plant in the garden. There is no need to keep the bulbs until spring. The old compost can be spread on the garden.

Thanks. I will try that
