Tips for Forcing Flower Bulbs

Crocus

Forcing a bulb means to coax a bulb to bloom out of season.  This process allows for indoor
color during times of the year when you would not naturally be able to have blooming bulbs.

 

 

 

 

STORING BULBS

Bare bulbs can be stored for several weeks prior to planting.  Store them in a ventilated bag in your Crocusrefrigerator.  You also have the option to pot your bulbs if you have an old refrigerator, root cellar or cool basement to store them in.  Bagged or potted bulbs need to be stored for 12 weeks at a temperature below 48 degrees, and then brought into a warmer temperature.

BLOOMING

After the 12 week cooling period you will want to pot your bagged bulbs, or move your potted bulbs into a warm sunny area.  After you have done this, you can expect approximately a three to four week wait before you have blooming flowers.

Spring BulbsTHE BEST BULBS FOR FORCING

  • Amaryllis (can be forced again and again!)
  • Colchicum
  • Crocus
  • Daffodils
  • Freesias
  • Hyacinth
  • Iris
  • Lily of the Valley
  • Muscari
  • Paper-White (Narcissus)    

Some varieties, such as tulips, are not a good choice for forcing since they require a longer cooling period and are more successful with an even temperature fluctuation.
