What does it look like?
Fennel is a flowering plant species of the carrot family with a strong aniseed smell. It is a hardy, prernnial herb that grows up to 2 meters tall. Fennel is often found growing along road margins and in environments that have been disturbed and degraded by human activity.
Fennel is native to the Old World - possibly the Mediterranean region considering its use by the ancient Egyptians, Greeks and Romans - but it has been widely introduced and naturalized around the world and today is reportedly an adventive species in the Americas and the Caribbean Islands.
Why is it a problem?
It can regenerate by both seeds and roots, which often makes physical control methods ineffective and chemical control necessary once a population is established.
- Grub individual plants ensuring the crown (first 15 centermeters of the root system) is removed.
- Overspary with 10ml glyphosate + penetrant per 1L water penetrant; or Tordon Gold at label rates; or Grazon at label rates
