Forcing Branches to Bloom

Winter can seem long and bleak, lacking any color. When the first leaves or blooms arrive in Spring, I love to pick a few and bring them inside. But you don't need to wait that long to see blooms, if you learn how to force branches to bloom in winter.

Early blooming bushes and trees develop their blooms early in the fall, before they go dormant for the winter (see list below for selected varieties to choose). Once the winter has been cooler then 40 degrees F for at least 8 weeks (usually mid-January), branches can be cut and brought inside to bloom. Bushes are easier to force then trees. Some take as few as 2 weeks to force inside while others will take 4 weeks or more. The later in winter you wait to harvest them (March versus January), the sooner they will bloom inside.


When choosing branches to harvest, it is best to choose a day in which the temperature is rising 10 degrees or more. This helps the branch get ready to be forced. Choose branches that have plump flower buds, which are generally larger then leaf buds. Cut the branch longer then you will need, as you will prune several times more before arranging the branch in your final floral display.


Bring your branches inside and prepare a bucket of water tall enough to support the branches upright. The water temperature should be warm (110 degrees F) and 3" deep to start. Re cut your branches above the original cut. If your branch is thick, make a 1" cut up the center of the branch to help it absorb water better. Place the branches immediately in water. Let the branches drink water for about 20-30 minutes, then add more water. Place the container in a cool room (60-65 degrees F) room, in a shaded location.


Once the buds start to show color, the branches can be moved to their final display vase. Re-cut the branch and place in clean water. To prolong their life, keep them in a cool location and out of direct sunlight. Enjoy!


Best bushes and trees to force: Currant, Quince, Forsythia, Pussy Willow, Witch Hazel, Alder, Crab Apple, Magnolia, Peach, Pear.
