Do I need to prune my viburnum?

Safety

People: Ingesting large quantities of berries from certain species may cause stomach upset or vomiting.
Pets: Most viburnum species are considered non-toxic to cats and dogs.
Children: The berries can be a choking hazard and may cause digestive distress if eaten in quantity.
Contact allergens: The fine hairs on the leaves of some species can cause minor skin irritation.
Airborne allergens: The pollen may cause mild seasonal allergies in sensitive individuals.
Edibility: While some species produce edible berries, many are mildly toxic or unpalatable, so do not consume unless you have positively identified the specific variety.

Growing it

Propagation: cuttings, seed, layering
When to plant: spring, autumn
Overwintering: Apply a layer of mulch around the base to protect roots from temperature swings. No special winter protection is needed for established plants.
In containers: Dwarf varieties grow well in large containers, but they need a pot at least 50 centimeters wide to thrive.

Softwood Cuttings

Take 10 centimeter cuttings in late spring.
Remove lower leaves and dip the end in rooting hormone.
Place in a moist potting mix and cover with a plastic bag to maintain humidity.

Planting viburnums in groups of three or more helps ensure better cross pollination and a more natural look in the landscape.
