What does it look like?
Terrestrial or epiphytic fern which grows to 1m, with small, erect, scaly rhizomes which produce many long runners and round, 1-3 cm hairy potato-like tubers. Fronds (40-100 x 5-8 cm) are erect or arching when long, with serrated, divided leaflets.
Why is it a problem?
Spreads by spores, runners and tubers, and forms dense, long-lived patches which are often large. Grows in the damp or dry, on the ground or in trees, in the open or the shade, in most soil types and in hot to moderately cool temperatures.
Crowds out groundcovers, shrubs and other ferns, and can contribute to streamside erosion.
- Pull out dry thoroughly and leave on site to rot down. Dispose of tubers and runners at a refuse transfer station, burn or bury.
- Spray with 1g metsulfuron-methyl (600g/kg) per 10L water. Leave sprayed sites 3-4 months to allow herbicide to translocate to tubers before clearing or replanting.
CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
