Growing it

Propagation: cuttings, seed
When to plant: spring, early autumn
Overwintering: Apply a layer of mulch around the base to protect roots from temperature swings. In very cold areas, wrap the plant in burlap to prevent winter burn from drying winds.
In containers: Boxwood grows beautifully in containers, provided the pot is at least 40 cm wide and has excellent drainage.

Semi-hardwood cuttings

Take 10 cm cuttings in late summer.
Remove the lower leaves.
Dip the end in rooting hormone.
Place in a moist, well-draining potting mix.
Cover with plastic to maintain humidity until rooted.

Pair boxwood with shade loving perennials to create a lush, layered look in formal borders.
