Why it’s bad Cane Grass forms dense thickets offering little of value to native fauna. It chokes waterways and prevents native species from regenerating.

Control Hand control is effective if you poison freshly cut stems, but extremely hard work. Gradual, piecemeal control is preferred, as it allows wildlife to relocate.

Alternatives Replace with Blue Flax Lily (Dianella caerulea), Native Raspberry and other pioneer plants or native grasses such as Kangaroo Grass and Barbed-wire Grass.
