Despite the common name, not actually a fern - its a scrambling or climbing evergreen fern-like perennial. Feathery flattened stems (cladodes) look like leaves, in bunches of 7-20 from each stem node.
Forest margins, farm hedges, roadsides. Prefers moderate to high light intensity. Tolerates dry conditions.
Seed dispersed by birds. Spread from garden debris.
Less impact than climbing asparagus or smilax. Competes with forest regeneration.
Regular follow up required.
1. Hand pull small infestations; dig out all roots.
2. Larger infestations: cut stems at 60cm above ground & spray/paint remaining stems (5g metsulfuron/1L).
3. Where vegetation beneath is not desirable, overall knapsack spray (100ml glyphosate+20ml penetrant/10L).
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
