A weed is an unwanted plant, growing in the wrong place. Weeds cause problems because they are hard to kill or spread faster than they can be controlled. Weeds are one of the biggest threats to New Zealand’s parks, coastlines, wetlands and alpine areas because native plants don't compete well with weeds for water and food.
The number of weeds found in a reserve is linked to the number of gardens nearby. Most of these are plants that have 'jumped the garden fence' and gone wild.
If you live near a community of native plants, the decisions you and your neighbours make will affect the survival of those plants.
What to do
- Take a good look at what’s growing in your garden and in local areas around you.
- Use iNaturalist NZ to help you work out what the plants are and which ones might be weeds.
- Visit Weedbusters find out the best way to get rid of the weeds you’ve found.
- Remove if safe to do so or tell someone what you’ve found and what they can do about them.
Some weeds, like gorse and nettles, can be very prickly so make sure you wear gloves before touching them.
