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 Problem:

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.

Control:

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.

Control

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.
