What is Field Horsetail?
Field Horsetail (Equisetum arvense) is an aggressive, deep-rooted invasive plant species known for its tall, hollow stems and brush-like appearance. It can grow up to 1 – 2 feet tall and is often mistaken for grass or ferns.
A closely related species, Marestail (Hippuris vulgaris), is typically found near or in water and poses similar challenges.
Originally introduced to the UK from Europe during the 18th century for ornamental use, Field Horsetail has since spread rapidly and now poses a significant ecological and structural risk across Scotland. This tenacious weed thrives in damp environments such as riverbanks, roadsides, railway embankments, and disturbed ground.
How Does Field Horsetail Spread?
Field Horsetail spreads primarily through its extensive underground rhizome system. Even the smallest fragment of root left in the soil can regenerate, making it notoriously difficult to eradicate without professional help. It also produces spores in spring which are dispersed long distances in the wind contributing to its spread.
Once established, Field Horsetail can quickly overtake landscapes, crowding out native plants, damaging habitats, and presenting challenges to construction and landscaping projects.
Issues Caused by Field Horsetail
Is Field Horsetail Harmful?
While not toxic to humans or animals, Field Horsetail is considered harmful due to its aggressive growth, deep-rooted structure, and resistance to common weed killers. Left untreated, it can:
- Undermine hard surfaces such as driveways, patios, and paving
- Obstruct drainage and infrastructure
- Delay construction schedules
- Compromise ecological balance by displacing native species
Identification of Field Horsetail Throughout the Year
Seasonal Growth Cycle
Spring
Shoots emerge rapidly with brown, cone-like structures that release spores.
Summer
Dense, green, brush-like foliage appears, making identification easier.
Autumn
Growth begins to die back, though rhizomes remain active underground.
Winter
Above-ground growth disappears, but roots remain dormant and ready to reshoot.
