@ZoeHayes I read a couple of websites for advice. I forgot to feed but repotted in fresh houseplant compost. I'm not too worried that this is later flowering than last year. The first year the bulbs have been prepared or forced to be flowering around Christmas time and have used up a lot of energy to do that which isn't the natural time. 2 others I had in winter 2015 are flowering now in their second year so I'm quite pleased as I hadn't grown one before 2015.
