Broad Leaf Privet - Ligustrum lucidum

B    road-leaf Privet is a tall shrub that grows up to 4m high. It can infest disturbed land, native
     bushland, moist nutrient rich sites eg. creeks, gullies, down slope of stormwater drains. It
     occurs on relatively undisturbed sites and hillsides on shale soils. Once established, it can
totally replace a diverse mix of native plant species.

During spring and early summer, large amounts of pollen are produced which cause allergic
reactions in some people. The fruit of Broad-leaf Privet is also reported to be poisonous to

Requirements of the Noxious Weeds Act 1993

Under the provisions of the Noxious Weeds Act 1993, Broad-leaf Privet is classed as a Class 4
weed. This means that the growth and spread of the plant must be controlled according to the
measure specified in a management plan published by the local control authority and the plant
may not be sold, propagated or knowingly distributed.

How does it spread?

Mature plants can produce a million or more fruits in a favourable year. Privet berries are eaten by
birds which spread the seed widely into previously non-infested gardens and bushland. Seeds can
also be distributed through waterways. If these shrubs are cut off at the base, without follow up
with chemical treatment, they are well known to regrow shoots from the base and often grow new
plants from the roots.

Methods of Control

To comply with legislation, flowers and fruit must be pruned from the plant on a yearly basis. This
is a time consuming procedure and it is often recommended (though not a legal requirement) that
trees be completely removed.

Small seedlings can be manually removed. Larger plants and clumps of Privet should be removed
and chemically treated. Cut stump and paint with chemical immediately after cutting. This will
prevent regrowth from the stump which will occur if the plant is not poisoned.

A number of chemicals (herbicides) are available for the treatment of Privet:

READ THE LABEL - it is an offence to use a herbicide in a manner contrary to the label. Take
particular care if the weed you want to eradicate is near a dam or waterway. If possible, avoid
using herbicides near waterways as they can harm fish and other aquatic organisms.
