Forcing Bulbs for the Holidays
The days seem to be passing rather quickly and with the arrival of Thanksgiving, the winter festivities have begun so now is the time to ‘force’ some bulbs for Christmas. For those unfamiliar with the process, ‘forcing’ is the method by which a bulb is planted and compelled to grow and bloom out of season by exposure to the warm temperature indoors. This process brings the bulbs into bloom long before they would bloom outdoors thus allowing us the pleasure of their company during the winter months.
Since their ancestors came from warm areas of the Mediterranean the darling Paperwhite Narcissus requires no cold to bloom and may easily forced. Taking only three to four weeks to flower, they will bloom faithfully providing both fragrance and cheer for the holidays. So easy is the growth of these bulbs that anchoring material may include gravel, pebbles, colored glass stones, or moss as acceptable mediums. Any sort of shallow growth container whether pottery, glass, or clay will work as well.
First select large, top-grade, flawless bulbs which are free of sooty mold then choose a favorite container that will be lovely as a centerpiece or focal point. Perhaps select a glass bowl for the added pleasure of watching the roots as they begin to grow and slowly twine about the stones. Grandmother’s shallow crystal bowl filled with red, white, and green glass stones is lovely at Christmas but more a more rustic selection might include a pottery bowl with polished rocks or pea gravel. If a large container is chosen, more bulbs will be needed and the display will entirely riotous… often more is better!
Fill the bottom of the container with whatever you have chosen to anchor your bulbs making a bed about two to three inches deep. Gently press the bulbs halfway down the bulb mass, wriggling and carefully nestling them until they stand firmly on their own. Try to space the bulbs about two inches apart, remembering to place several in the center as well. After arranging your bulbs, fill the container with enough water to cover your anchoring material, moistening the bulbs approximately half way up. Keep this water level, adding a little each day if necessary and your bulbs will begin to flower in three to four weeks. Remember to give the bowl a shot of gin as the first flower buds appear. The gin will slightly stunt the foliage and force it to stand ‘at attention’ thus preventing the wilt so prevalent with forced Narcissus. (My friend Linda Vater, who presents a gardening segment on Channel 4 Thursday afternoon, uses 1 part Vodka to 7 parts water.)
As the roots grow, the reed-like foliage will first appear and suddenly many tiny blooms arrive, slowly swelling, then opening over the course of several days. The marvelous sweet smelling flowers will last several weeks before it is time to discard them. Sadly, the temperature-trickery used to force early bloom has confused and destroyed the bulb’s internal clock... they have given their ’all’ this season. After the display is over leave them in a cool place and plant them outside in the early spring. Often they will recover and bloom on schedule in a year or so.
