I just answered this exact question on the phone to my friend....
I got a pot of hyacinths....any spring
flowering bulbs like tulips, daffs get planted in the fall......
Forced bulbs don't always reflower good though...I've had good luck with mine so it's worth trying.
When the flowers
die put the pot in the brightest location you have inside...like a window ledge or under a light....Let the foliage die all the way down.....the foliage has to collect light so it can flower
next year, that's why you leave it to die back.
When it's totally died down, cut the dead foliage off and dig the bulbs out...store them in a cool, dry place in a bag...I put mine in the basement....
Come fall you can plant
them outside about 6-8 inches down...I cover mine with a few leaves and that's it.
With forced bulbs sometimes they don't come up good the next year....like I said, I've had good luck with mine coming back up!
