What is Marestail / Horsetail?
Horsetail is a highly invasive, deep rooted perennial weed which has fast growing underground stems which will quickly send up dense stands of foliage.
Identification & Occurrence:
It is easily recognised by its straight upright fire tree like shoots which appear in summer. In the spring, the plant will be around 20 - 50cm tall and fertile brown stems will appear with cone-like spores at the end of the stem. In the summer green shoots develop into fir tree like plants.
The plant has creeping rhizomes which can go down as deep as 7m which makes them extremely difficult to remove, especially if they are invading a border. They are known for entering gardens by spreading underground from neighbouring land or properties. Horsetail / Marestail is fast becoming the biggest problem weed in the UK growing through driveways & paths, as well as covering industrial sites.
The plant can be dug out but deeper roots will need excavating, and even the smallest piece left behind will likely re-grow into a new plant. There are very few chemicals that will control this weed and glyphosate alone will do little to stop it.
Since Pearl & Kurtail were removed from the market, the only available product to control this troublesome weed is Diamond.
We recommend using a product specifically designed to target Horsetail, for example Diamond. This product is ideal for the job as it contains both 2,4-D and glyphosate. After application the 2,4 - D will break down leaf tissue which enables the glyphosate to translocate around the plant far quicker and deeper.
