How To Force Flowering Branches Indoors

Why wait for spring when you can savor it in winter? Forcing flowering trees and shrubs to bloom is as easy as 1-2-3. All you have to do is cut a few branches, bring them indoors and follow the instructions below.

Harvesting the Force of Nature

By mid February, many spring-blooming trees and shrubs are thick with buds. Unfortunately for the winter-weary, though, they’re still weeks away from flowering. The good news is that forcing their branches can speed up the process.

The time it takes to force flowering branches to bloom indoors is dependent on the species you select. Early spring bloomers like forsythia, star magnolia, quince, witch hazel and pussy willow, for instance, are typically the fastest to flower. Cherry and dogwood tree branches, on the other hand, can take up to four weeks to develop. A lot depends on when you cut them. In general, trees take longer than shrubs to force.

HINT:  The closer to a plant’s natural bloom time you harvest, the less time it will take to force its branches to bloom indoors.

A Guide To Forcing Flowering Branches Indoors

Step 1

Start by selecting a few medium-sized branches with lots of plump buds that look ready to open. Then cut the branches from the tree or shrub using a pair of pruners. Make sure to cut on a diagonal, which creates a greater surface area for water uptake.

Step 2

To protect your flowering branches from rot, remove any twigs or buds from the bottom six inches of the stem. Then do one of the following: either slit the branches in several directions at the ends or mash the branch ends against a hard surface. Both methods will cause the base of the branch to splay out and encourage it to draw up more water. It will also keep the branch fresher longer.

Step 3

Submerge the branches overnight in cool to lukewarm water. (A bathtub works great.) This enables the branches and buds to more rapidly absorb water and to begin breaking their winter dormancy.

Step 4

The following day, remove the branches from their bath and place them upright in a bucket or vase. Next, add warm water no higher than a few inches. Place the branches in a cool location away from direct sunlight. (Warm temperatures may cause the buds to develop too rapidly or fall off.) To limit bacterial growth, make sure to change the water every few days.

Step 5

Once the buds begin to show color, arrange the branches in a container and place them in a bright spot away from direct sunlight. This will encourage the best flower color to develop. Always make sure to keep them away from heat sources. Spring-flowering branches bloom longer in cooler temperatures.

Forcing Branches Can Spawn New Plants

Occasionally when flowering branches are being forced, some will start sprouting roots. You can sometimes grow a new plant by potting them up and trimming them down to about 6 to 8 inches. When warmer weather arrives, plant them outdoors.

Top Choices for Forcing

Below are some of the more popular flowering branches for forcing and the time it takes to force them indoors. Bear in mind that this represents the long end of the scale, assuming you start cutting your branches in February. Remember, you can shorten the forcing time by harvesting the branches closer to the plant’s natural bloom period.
