Prevent establishment of Field Horsetail

Field horsetail (Equisetum arvense) is a very difficult to control perennial weed that regrows each spring/summer from an extensive underground root system. Preventing establishment is the best form of control. Make sure your contractors machines are clean and ask where the machines have been.

This root system comprises actively growing rhizomes that can penetrate to more than 1 m in depth, from which green fern-like fronds grow each year. Attached to the deeper rhizomes are small tubers which remain dormant while the rhizome stays alive. Upon the death/decay of the rhizome, or when it becomes detached due to cultivation or other means, the tubers are able to produce new plants.
