Is horsetail rush invasive?
Horsetail is common along roadsides as well. Both horsetail and scouring rush spread by spores and rhizomes. Impacts: Horsetail is so invasive and difficult to control that it is very important to prevent it from becoming established.
How to control horsetails?
Horsetail control methods. Prune off the Horsetail stems as soon as you see them. By doing this you are blocking the food supply of the plant. Cover the cut Horsetail plants with a black cover/landscape fabric to prevent the leaves from food assimilation.
How to kill horsetail weeds?

You can also use grass trimmers to achieve the same. Now spray ample amount of 2,4-D on the cut Horsetail plants.

Chemical Weed Killer
Horsetail ( Equisetum arvense) has a hard waxy cuticle that makes it difficult to kill with herbicides. But if you use them in the right way it’s possible to control the plant.
Using A Pre-Emergent Herbicide
A good way to control the growth of horsetail is to use the pre-emergent herbicide Casoron. It won’t kill the horsetail plants that are already growing. But it will prevent the growth of new shoots.
Use Vinegar As A Natural Weed Killer
Vinegar is good at killing horsetail above the ground. But the normal table variety isn’t strong enough to do the job. Instead, you need to get high-strength vinegar with an acetic acid concentration of around 20-30%.
Change The Soil Conditions
Horsetail thrives in wet soil that’s low in oxygen, nutrients, and pH (acidic). So the best way to control it in the long term is simple:
Prevent It From Getting Light
Like other plants, horsetail uses the process of photosynthesis to create energy for it’s growth and spread. To do this, it needs access to sunlight.
Dig And Sift
If you’re happy to start from scratch in the infested area you can try to kill horsetail weed by digging and sifting.
Killing Horsetail With Fire
Killing horsetail with fire can be an effective method. But similar to cutting the plant down, it requires commitment to the process over a period of time.
How to get horsetails to die back?
Make sure to follow the package directions carefully. Start improving the soil once the horsetail ( Equisetum) has died back. To do so, amend the soil with manure or compost to improve its fertility, texture, and drainage. You can also plant the area with grass or perennials.
How to grow horsetails?
If you want to grow horsetail put plastic barriers in the soil or plant them in a deep pot. You can then bury the pot in the ground. Horsetail plants are not fussy. When it comes to fertilizer it is often unnecessary.

What is the hardiness zone for horsetail?
Gardeners who have experience with horsetails understand how this plant has survived for close to 350 million years. Today, horsetail, also known as ‘scouring rush’, is grown as a perennial in USDA zones 3 through 11. It is a fast-growing plant that can reach up to 4 feet tall and 6 feet wide.
Can horsetails grow in soil?
You can also plant the area with grass or perennials. Horsetail prefers poor growing conditions and may not grow in fertile soil. One option is to lay down landscaping fabric and mulch your garden. Do this only after you have cleared your garden of all the spore-bearing stalks.
Do horsetails need fertile soil?
They do not need fertile or rich soil. If your horsetail plant is struggling, you can use slow-release plant food to boost its growth. The plant grows best with high humidity and hot sun.

What are horsetails called?
Scouringrushs and horsetails are known by many different common names such as snake grass, jointed grass, monkey grass or simply Equisetum to name a few. They all belong to the genus Equisetum and the USDA’s plant database indicates that there are 13 species in the Mid-West. The species are separated into different subspecies by stem thickness, frequency of the vegetative form, stem height and various other subtle clues. One thing that is unique about the equisetums is that they do not produce flowers or seed and spread primarily by vegetative means. To learn more about its life cycle please read “ The Ancient Horsetail (WS-29-W) .” For the purpose of this article, the two species that we typically deal with, field horsetail ( Equisetum arvense) and scouringrush horsetail ( E. hyemale ), will be referred to as horsetail and scouringrush, respectively.

Although typically not a widespread problem in corn and soybean fields, Equisetum is more of a problem around ponds and drainage ditches ; however, both horsetail (an Equisetum that produces a small branched vegetative stems) and scouringrush (a species that only produces the reproductive stems) often find their way into agricultural fields.

What is Scouring Rush?
Scouring rush and field horsetail are two species in the Equisetum genus. These are primitive plants that produce spores rather than seeds, but they spread primarily by underground rhizomes.

Repeated mowing or tillage is one option, but it will take at least two years of disturbance to control/eradicate the weed. Chlorsuluron (Telar) is one herbicide that has good activity on equisetums, and it is registered for use in sites such as roadsides.
Can herbicides kill Equisetums?
Few herbicides used in crop production have any effect on the equisetums . Tillage can suppress the weeds, but it probably would take several years of intensive tillage to eradicate them from fields. Most infestations of these weeds are due to a source population in adjacent non-crop areas.
