Horticulture - Weed control Weeding in the open grounds of the
Gardens is done by: - using mulch to smother the weeds - manual
removal of weeds – by hand, gardening fork, hoe - application of
herbicide around paths, around the edges of beds and directly on
weeds The herbicide for killing weeds includes a non-toxic red
dye. This gives the horticulturists a visual aid to know where
they have sprayed. Safety precautions taken when spraying
include: - wearing protective clothing and masks - not spraying
when windy - not spraying near other people - not spraying near
the ponds - aiming directly at the weeds, not spraying randomly
Due to staffing limitations and the relative inaccessibility of
some areas it is impossible to remove all the weeds. The high
visitation areas are kept relatively weed-free – especially
around the Visitor Centre, Hudsons Café and the Main Walk. Each

Gardens. This is more of a problem in the bushland areas, at the
top of the G
