Forcing Tulip Bulbs

Pots of blooming bulbs during the dark days of winter brighten and lift our spirits while we wait for the real spring to make its appearance. October and November is the time to pot these bulbs in order to force them to bloom in the late winter.

Begin by purchasing top quality, good-sized bulbs from a reliable source. Six bulbs per pot make a good display. However, since flowering dates vary, it is best not to mix varieties in the same pot.

Fill a clean plastic or clay six inch pot about two-thirds full with good potting soil - it is preferable not to use garden soil.[1] Place six bulbs on top of the soil being sure that the flat side of the bulb is next to the rim of the pot.[2] This placement permits the largest leaf to grow on the outside providing more stability to the elongating flower stem. Cover the bulbs with more soil, leaving just the tips visible and water thoroughly.[3]

The bulbs need a mock winter for 10-12 weeks, so place them where the temperature will be 35-45 degrees - an unheated attic or cellar, an attached garage, or a refrigerator are good locations. Just be sure they do not freeze. Keep the pots in the dark by placing a box over them. Check them periodically to be sure they do not dry out, and water only enough to keep them moist, not wet.

After 10-12 weeks of a cold treatment, place the pots in a 50 to 60 degree sunny location until the shoots and leaves begin to expand. After this initial adjustment period, you can move them to your living area to enjoy.
