7 ways to get rid of Horsetail Weeds

Here’s some ways to get rid of horsetail weeds in your lawn:

1. Killing it with fire

Horsetail weeds can be killed by scorching them with a propane torch. After the first scorching, the weed will return. Scorch the weeds as soon as you notice fresh shoot growths, and you’ll be able to get rid of them in a few seasons. It is because you weakened the rhizomes by frequently scorching the shoots.

2. Dig and sift methods

Using this method, dig up all the horsetail plants in the area and discard their rhizomes (the foliage can go into the compost). Now, empty the soil bed to a depth of 1 foot (30 cm) and sift it through a soil sifter (easily manufactured from a wooden frame coated with 14 inches (6.4 mm) wire mesh) to remove any rhizomes you detect before replacing it. Some tubers may be left in the soil and sprout into young plants. If you pluck these out within a few weeks, they won’t have time to create rhizomes, and you’ll be able to prevent the formation of a new colony. This technique is useful for limited infestations.

3. Pull it up

Pulling up horsetail weed every time you see it is the easiest approach to get rid of it. The more you remove the tops of the plants, the weaker underground portions will become. The young shoots can be harvested, cooked, and consumed as an asparagus alternative. In addition, the plant is used in herbal medicine. So, rather than weeding, you might discover a use for the plant and consider it harvesting.

4. Chemical eradication

It is necessary to be persistent when using chemical methods to kill horsetail. Follow the guidelines carefully while using any herbicide and wear gloves, goggles, long pants, long sleeves, and closed-toe shoes or boots. Before the pinkish-yellow domes containing the spores develop, cut back as much of the weed as you can.

To avoid spreading the spores, work carefully and dispose of all trash in a tight plastic bag. Apply a glyphosate-based herbicide straight to the weeds that have been clipped. This often kills only the top portion of the weed, allowing it to re-grow, necessitating multiple treatments to eliminate the weed.

5. Dolomite lime

Horsetail weed can be effectively eradicated using dolomite lime. Follow the instructions on the packaging before applying dolomite lime to the soil. Depending on your soil type, you may need to change the amount of dolomite lime used. In such instances, clay soils require a large amount of dolomite lime. After applying the dolomite lime to the soil, work it in with a shovel or a rake and thoroughly water the area. To eradicate Horsetail, repeat this process once or twice a year for 5 years.

5. No sun, no horsetail

Horsetail can be eliminated by preventing it from carrying out photosynthesis. The plant will swiftly stop spreading if its leaves are not exposed to the sun, and it will finally exhaust itself and die. Covering the contaminated area with a black tarp is one way to block out the light. To completely eradicate horsetail, you must leave it in place for 24 months; if you remove it after only 12 months, there is a bit of regrowth. This strategy is only useful if you’ve decided to start from the beginning.

6. 2,4 D

Spraying 2,4-D on Horsetail weeds works wonders in eliminating the weed. Horsetails have a protective waxy covering on their leaf, therefore spraying 2,4-D directly on them won’t work. Cut the Horsetail weed to a 2-inch height off the ground. Grass trimmers can also be used to achieve the same results. Apply a generous dose of 2,4-D to the Horsetail plants that have been clipped. Take a look at those weeds in a week or two and you’ll notice they’ve vanished. Unlike other methods of eradication, 2,4-D eliminates Horsetail weeds.

7. Cut the green stems

In a developed garden, one method is to simply cut the sterile stems (green stems) to the ground anytime you see them. Unlike cultivation, which spreads the rhizomes, this weakens them because the plant is unable to carry out photosynthesis. Begin early in the season and re-cut as the plant grows back. The plant will eventually die if you keep doing this every time a new shoot appears. This method, however, requires some effort: you may need to trim horsetail back 5 or 6 times the first year, and some stalks may still grow back in year 2 and need to be chopped.

Key Takeaway

As previously mentioned, horsetail weed is difficult to completely eradicate, especially in a dry, sunny location. However, it may be better to simply confine it by ‘harvesting’ it regularly, as described above, and to live with it showing up now and then. After all, it’s a nutrient-dense plant with a unique nutritional profile. When not allowed to take over, they can be beneficial to the environment as a whole. Some people claim that because of its feathery appearance, it can be used as an ornamental plant, enhancing the visual appeal of your yard.
