Q:Why is Old World Climbing Fern so difficult to control?
A: Old World Climbing Fern (Lygodium) produces copious spores that are spread locally with normal wind currents and further spread long distances by hurricanes. Once established, OWCF exhibits a twining, climbing growth habit that wraps around and covers native vegetation, making herbicide control difficult without causing non-target damage. Small infestations which blend in with native vegetation are difficult to observe.
