Fennel
Apiaceae - Foeniculum vulgare

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.

Control Methods

 Physical control

  • Grub individual plants ensuring the crown (first 15 centermeters of the root system) is removed.

Herbicide control

  • Over spray with 10ml glyphosate + penetrant per 1L water penetrant; or Tordon Gold at label rates; or Grazon at label rates.

CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
