Members of our local WI were each given a hyacinth bulb before Christmas to
grow on to bring into flower for our February meeting. The results were
extremely mixed!!! But what do we do with the bulbs when they have finished
flowering.

We have tubs and a small garden at our village hall which the WI look after.
Is there any point in planting the bulbs - i.e. will they flower again next
year?

It's been a while since I had a healthy looking hyacinth bulb at the end of
flowering, but I /believe/ you should treat it approx like an amarylis,
which iirc:
* cut off the flower and let the green keep growing
* when the green dies off, stop watering the bulb
* when the bulb has dried out enough not to rot, store it in a cool dark
place
* - should be ready to use again next year.

(you need to let the green keep growing to replenish the energy stored in
the bulb that has been taken out by the flower - in theory I guess you
could put the whole planted bulb somewhere cool and dark rather than remove
it from its vase/soil)
