Growing it

Propagation: cuttings, seed, layering
When to plant: spring, autumn
Overwintering: Apply a thick layer of mulch around the base to protect roots from freezing temperatures. If in a container, move it to a sheltered, unheated area during extreme cold.
In containers: They grow well in large containers, provided you use a well-draining acidic potting mix and a pot at least 40 centimeters wide.

Semi-hardwood cuttings

Take a 10 centimeter cutting in late summer.
Remove the lower leaves and dip the end in rooting hormone.
Place in a moist, sandy potting mix.
Cover with a plastic bag to maintain humidity.
Keep in bright, indirect light until roots form.

Group plants that require acidic soil together to make soil amendment easier.
