Daffodils in pots

This year (well, autumn) I planted up several pots with daffodils, both normal size and little ones. Now they are coming to an end of flowering I know I should just snap off the flowering heads and leave them to die down.
I have a couple of questions I'm hoping someone can answer:
a) "They" talk of giving the plants a foliar feed- is that something special or can I use a dissolvable general purpose food? And how often? Just the once?
b) When the leaves have died down I was planning to hide the pots round the back of the house and they will be under the eaves. Will they be OK without any water or should I be nice to them?! I sort of assumed they were dormant and didn't need anything but the ones planted in the garden get frequently rained on so I just wondered. Don't want to kill them off!
Thanks in advance for any advice.

 

Hi Fuchsialady,

The feeding I'll get to in a minute ( you'll see why ! ).

Why do you want to hide them away ? I have loads of Narcissi/Daffodils in pots from miniatures to large doubles. Mine are all overplanted with summer flowering plants, Lilies or Fuchsias, and even Roses.

Now, they'll get a good feed in the next couple of weeks and then when the other plants get fed then so will they. Now you can see why I left the feedy bit to the end

 

When my tulips and daffodils have flowered, I take them out as they are, put them in onion sacks and hang them on hooks in the garage to die back. Then I get rid of what bits are left iand leave the bulbs in the sack until I replant them again in late autumn.I didn't know whether you could do this or not so just had a go. The bulbs were fine and re-flowered this ŷear.

Although my spring tubs and baskets look lovely now, I need the pots and baskets again for the summer plants.

 

Most of the pots are full of daffs so I can't overplant them (although there is one not very full so I probably will stick something else in - thanks for that idea!). It just seemed like a good idea to have a mass of flowers in the back while there was nothing else and I had some spare pots. I don't have the time/energy to lift them and dry them out so they'll have to stay where they are.
Will they be ok left alone?

 

I used seaweed feed on my potted bulbs last year and they have come back ok.

 

Hi Fuchsialady,

Just make sure that they don't dry out completely during the Summer. Can't you just sow some annuals on the top the pots and sprinkle a little compost over them. I'm thinking something like Candytuft, Godetia, Clarkia, Cornflower or other hardy annuals.
