Daffodils - how long to die back

I think it the leaves are still green it is worth feeding them - and Tomato feed would be just the job

 

I feed the Daff clumps in the lawn mid May , just give them a good watering with Tom Feed . I'll be cutting them down to lawn level this weekend , although they are tete a tete type which do seem to flower and die back earlier.

 

I love them Being a species they will self-seed (if you let them / want them to )

 

Rose food is also very good for daffodils, but that works out dearer than tomato food.
