My bulbs are flowering beautifully in their pots. Should I be feeding them at all to ensure that they come back next year or do I leave it to Mother Nature. I am unsure about tulips in particular because I have often read or heard people say that it is not worth trying to get more than one year out of tulips which has always seemed an awful waste to me. Is it possible by feeding and looking after them properly through the winter to get them to flower next year? Any advice would be gratefully received.
