Pittosporum Control Methods

Drill and fill

Drill holes 2-3 cm deep and space holes at around 5-7 cm apart around base of trunk. Fill the hole immediately with undiluted glyphosate product. This technique can be utilised on trees greater than 45 mm in diameter. It is best to undertake this procedure in the active growing seasons of spring and autumn.

Ring Barking or Frill and Fill

Using a saw cut the trunk of the pittosporum and apply chemical on the exposed area.  Chainsaw cuts can be applied to trees that have been cut and painted to allow greater absorbtion of chemical.

Cut and paint

using a saw or loppers, cut the sapling as close to ground level as possible. Immediately paint the stump with glyphosate to discourage re-growth. This technique should be deployed on plants that are between the 'hand pull' stage and 'drill and fill' stage.
