Tradescantia (wandering willie)
If your dog has been running in an overgrown area and comes back scratching, chances are it might have encountered tradescantia.
‘Tradescantia is an abundant and well known invasive pest plant in our region. Always start weeding it out from the highest point it is growing at, and bear in mind that if you or your neighbours have chickens - apparently they love it! If you leave it to rot down under black plastic, it is said to form a very nutritious compost, as long as it is well and truly rotted down.’
Katrina Merrifield, Biosecurity Advisor at GWRC
Tradescantia is a major problem under trees and in bush reserves.
It spreads over the forest floor, covering the ground so that nothing else can grow and is very hard to get rid of.
It can also intensify flooding on riverbanks and causes allergic responses in dogs.
We control tradescantia 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.
