Old man’s beard
Beautiful to the eye, but noxious in nature, old man’s beard is a weed that plagues many gardens.
'Old man’s beard is an environmental weed that can spread rapidly and prevent the establishment of native seedlings. If everyone does their bit to keep their neighbourhood free of Old man’s beard, we could see the reduction of its distribution in the Wellington region.'
Katrina Merrifield, Biosecurity Advisor at GWRC.
Old man’s beard is a threat to native species. It prevents the growth of seedlings and development of established plants, spreads quickly, and can strangle the lowest shrubs to the highest canopies.
Old man’s beard grows in most soil types and flourishes in almost any climate. It is an extremely hardy and particularly difficult plant to eliminate. Wind carries its seeds so it can disperse over large areas fast, and if large roots are left behind, they may continue to grow.
It is an ongoing challenge for councils to keep up with old man’s beard because it grows rapidly. We need every helping hand to keep this plant under control.
We control old man's beard in our region's Key Native Ecosystems to protect each site's unique plants and animals. You can control this pest on your property with these methods:
Once the area is fully clear, plant and mulch to minimise regrowth and support local biodiversity – the plants and animals that naturally occur in the area.
If herbicides have been used, read the label for information about when to replant.
Check for regrowth at least every 4 months and continue to clear and spray if needed.
