Paperwhite narcissus is the tender relative of the hardy daffodil bulb. Paperwhites do not tolerate cold weather at all, but they grow well indoors and are often forced into bloom in mid- and late-winter. Bulbs are usually purchased in fall for forcing, but you may need to store the bulbs for four to six weeks prior to planting, depending on when you want them to bloom. The bulbs can also be stored after flowering for replanting the following year.
Place newly-purchased paperwhite bulbs in brown paper bags. Fold the top of the bag over loosely, and store in a in a dark place at room temperature until you are ready to plant.
Cut off the flower stem at the base of previously forced paperwhites after the blooms have wilted, using clean shears. Place the pot in a sunny windowsill until the foliage yellows and dies back naturally in late spring.
Cut the foliage off 1 inch above where it emerges from the bulb once the foliage has died back. Lift the bulb from the soil and brush off the excess dirt.
Place the bulbs into a brown paper sack, and fold the top over loosely. Set the paperwhite bulbs in dark, dry room until ready to replant.
Alternately, leave paperwhite bulbs in the pot, but stop watering the soil. Store the entire pot in a dark, dry room until you are ready to force the bulbs again the following fall or winter.
