Q&A: Forcing Bulbs
Question: Which bulbs are best for forcing, and how do I go about it?
Answer: You can force quite a number of spring-flowering bulbs, including daffodils, tulips, grape hyacinth, and crocus. Forcing refers to pushing the plants for early bloom by putting bulbs through a chilling period to OtrickO them into thinking itOs spring. Pot up bulbs in a shallow container in moist potting soil, leaving the tips visible above the surface. Place them in a refrigerator or sheltered place where you can maintain a temperature in the mid 30's. Make sure the soil doesn't dry out completely, but donOt saturate it either. Eight weeks of chilling is adequate for some small bulbs like crocus and grape hyacinth, but most will do better with at least 10 weeks of chilling. After this chilling period, bring the container out into indirect light, and keep the soil moist. As soon as green shoots appear, apply more water and move them to brighter light. They should bloom within a few weeks.
