Thanks for the suggestions so far. I did remove the leaves to about 10" below soil level a few weeks ago but they are already showing through again. Encouraged to hear it probably is a matter of just persistently trying to weaken the bulb over a few seasons.
I was thinking that a bit of chemical help would speed things along - just wasn't sure whether glyphosphate worked on bulbs or not.
Spanish bluebells, Steve J - I understand - have a similar problem with celandines all over the place - pretty - but looking way too much like weeds now!
