You can force quite a number of spring flowering bulbs, including daffodils, narcissus, tulips, grape hyacinth, and crocus. Forcing refers to pushing for early bloom by putting bulbs through a chilling period or false winter.

Pot up bulbs in moistened potting soil, leaving the tips visible above the surface. Place them in a refrigerator or outdoors in a sheltered place where you can maintain a temperature in the mid-30's F. (Don't let them freeze.) Make sure the soil doesn't dry out completely, but don't overwater. Eight weeks does for some small bulbs like crocus and grape hyacinth, but all will do better with at least 10 weeks of chilling. Gradually bring them out into indirect light, and give them a little more water. As soon as green shoots appear, apply more water and move them to brighter light. They should bloom within a matter of a few weeks. Enjoy!
