How to Start a Boxwood Shrub From a Clipping
The hardy Boxwood shrub is a popular choice for hedges as it tolerates regular clipping better than most slow-growing evergreen shrubs. Propagating a boxwood shrub from a cutting is an affordable way to get new plants from an existing plant. The best time to take a cutting from a boxwood shrub for reproducing a new plant is from July to December.
Layering, another method of propagating boxwood, happens when roots develop on a stem while it is still attached to the parent plant. Pruning the stem from the parent creates a new shrub.

Fill planting container, such as a flat or tray with drainage, with planting media. The American Boxwood Society recommends an equal mix by volume of pine bark, coarse builder's sand and perlite.
-
2
Cut a 4 to 5-inch branch from the inside of the plant. This helps to increase air circulation and sunlight at the boxwood's center, according to MarthaStewart.com. The bigger the cutting, the more time it will take to root.

3
Remove 1 to 2 inches of leaves from the bottom of the cut branch.

4
Dip the bottom of the cut branch in rooting hormone or compound, if desired. According to the American Boxwood Society, nearly equal results are achieved whether the stem is treated with rooting hormones or not. If used, gently tap excess powder off the stem after dipping it.

Plant the stem in the planting container, using a small stick for support if necessary. Water the cuttings and place in a bright, indirectly lit window. Cuttings taken earlier in the season can be set outdoors in a shady spot with plenty of water and good drainage, according to MarthaStewart.com. Rooting usually occurs in two to three months. The plants can be planted out in a protected area the following spring.
