Old man’s beard is a vigorous growing vine which forms a tangled smothering mass over trees and shrubs, blocking out light and eventually killing supporting plants.
One plant is capable of blanketing an area of 180 m2. It seeds profusely and the seed can remain viable in the soil for several years. Stems can provide up to 10 m of growth in a season.
Introduced from Europe as a decorative plant, old man’s beard has developed into a major weed problem particularly in the central regions of New Zealand.

What we can do to help protect Canterbury
Seek advice from a Biosecurity Officer at Christchurch, Timaru, Kaikoura, Cheviot, Amberley, Darfield or Little River.
Will only succeed if all roots are dug out. When vines touch the ground they usually develop extra roots and all of these must be removed for control to be successful. Note: Just cutting the vines will result in rapid regrowth.
Check the site each spring for regrowth and new seedlings.
