Thanks, Morth.
I've only tried it here very occasionally and only with the very small daffodils.
Dierdre, at Merlin's Hollow, does it with hyacinths and says the flower still looks nice, but is less dense (more elongate?) than when the bulb previously bloom, forced in the pot.
I must try it with the variety of forced daffodils we're buying.
It's unfortunate that buying forced bulbs, in pots, usually means you don't get the cultivar name.
An issue here, with planting out perennials previously purchased for earlier spring indoor display, is that much of the ground may remain frozen into March/April.
This year, as said, a portion of our garden is still under snow and ice, even now.
