Answer: Paperwhites generally take four to six weeks, and there's no way to "make" them blossom at a specific time. However, you can control the time to some extent by keeping them slightly cooler to slow growth, and slightly warmer to speed growth. If you need them for a specific date you might start several batches about a week apart for insurance. You can also prolong the blooms by keeping them in a cool (60F) display location during the day, and then moving them to a cooler spot (45F) every night.
