Daffodils and most other bulbs can be left and in fact do better if you leave them in the ground, let the old foliage die back (don't tie them up), but dead head them as the flowers fade. Dig up the tulips and throw them out as they never do good the second year, only one out of ten might flower properly the second year. I have tried digging tulips up, shaking off excess soil and storing in a cool dry place over Summer (no need for fungicide) and then planting them again in November but with poor results. Just buy new ones! Hyacinths are the only ones I shake off soil (leave any little roots), and store over Summer for re-planting. I usually put them in a brown paper bag, not plastic, as that only encourages condensation etc. Again no need for fungicide.
