Growing it

Propagation: cuttings, seed
When to plant: spring, autumn
Overwintering: Apply a layer of mulch around the base to protect roots from freezing temperatures. Ensure the plant is well watered before the ground freezes.
In containers: Holly grows well in large containers, but ensure the pot is at least 40 centimeters wide to accommodate root growth.

Semi-hardwood cuttings

Take 10 to 15 centimeter cuttings in late summer.
Remove the lower leaves and dip the base in rooting hormone.
Place in a moist, well draining potting mix.
Cover with a plastic bag to maintain humidity until roots form.

Plant your holly in a spot with well draining soil and protection from harsh winter winds to keep the foliage looking its best.
