Natural Heritage Trust’s Key points on Horsetails
• Prevention and early intervention are the most cost-effective forms of weed control. Horsetails are so invasive and difficult to control that it is very important to prevent them becoming established.
• Horsetails can be spread over long distances by movement of soil containing rhizomes.
• If not controlled, horsetails could become persistent weeds of cultivated land, pastures and roadsides in temperate regions, especially on damp ground.
• If you see a plant that may be a horsetail species, contact your local council or state or territory weed management agency. Do not attempt control on your own.
