Forcing Flowering Bulbs

Bulbs that flower outside of their usual growing season can advance the joy of spring into the winter months. Some bulbs that can be easily forced are the ever popular daffodils, hyacinths and tulips. Other bulbs that be easily forced include grape hyacinth, crocus, glory-of-the-snow, netted iris, spring snowflake, summer snowflake, winter aconite and wood hyacinths.

To force bulbs to bloom, purchase bulb cultivars that are recommended for this activity. These can be found in local nurseries, discount retailers, and some local grocery stores. Cool the bulbs for twelve weeks, or use precooled bulbs. Use premixed potting medium or your own mix of equal parts potting soil, peat moss, and perlite. You do not have to fertilize the bulbs at this time. Fill the chosen pot with soil leaving at least two inches of soil beneath large bulbs. Position the bulbs and add mix to cover. Tulips and daffodils can have their tips showing, but completely cover smaller bulbs. Water your plantings. Starting with a cool 60-65 degree room with indirect light, expose the pots to light and temperature. When the shoots develop and the bulbs can be wiggled but stay in place, move the pots to a warmer temperature and more light. Rotate the pots to ensure that the leaves receive an equal amount of light. Keep the soil moist. The flowers will last longer if you move them to a lower temperature area (60-65 degrees) at night. Bulbs forced now will bring a promise of spring from December until outdoor flowering bulbs are developing.
