let the blooming bulb flower as it normally would
snip off the dead flowers and the stem, the floppy leaves can stay
water the bulb and set it somewhere out of the way until late summer, it may flop over but that's ok, water sparsely
alternately you can plant it outside, it will not flower but it adds interest to a flower bed and you won't have to look at it indoors
early September dig the bulbs, trim the foliage, knock off most of the dirt and slip the bulb(s) in a paper or plastic bag, fold loosely to let air circulate
Place the bag in the refrigerator
In mid to late November pull the bulbs, replant them and water them generously--you can re-use the cocoa peat from the previous year but add a little fresh growing medium to it, best to use one with a little fertilizer in it as well
water and set in a sunny spot and watch them grow
repeat steps 1-7 to regrow the bulb again and again
