My lawn is being overrun by yarrow, and I don't know how to stop it. Help!

Yarrow, commonly known as Achillea, is a type of plant that is often considered an invasive species in lawns. It is a hardy perennial that can quickly take over an area, outcompeting other plants for resources. Yarrow is known for its feathery foliage and tall flower spikes, making it a favorite among gardeners for its ornamental value.

However, for homeowners looking to maintain a pristine lawn, yarrow can be a nuisance. The plant spreads through rhizomes, or underground stems, and can quickly form dense patches of vegetation. Its runners make it difficult to control and eradicate. Yarrow is also tolerant of a wide range of soil conditions, further increasing its ability to spread and thrive.

So, what can be done to control yarrow in lawns? There are several solutions that have proven to be effective. One option is to manually remove the plants, making sure to dig out the entire root system to prevent regrowth. Another method is to use herbicides specifically designed to target yarrow. These can be applied directly to the plant or to the surrounding area, but caution must be exercised to avoid damage to desirable vegetation.

In conclusion, yarrow can be a big problem for homeowners looking to maintain a pristine lawn. Its ability to spread rapidly and tolerate a wide range of conditions makes it difficult to control. However, with the right techniques and solutions, it is possible to control yarrow and restore the health and beauty of your lawn.

Problem Overview

Yarrow is a commonly selected species for lawns due to its fine leaves and tolerant growing conditions. However, this plant has invaded my lawn, causing a problem that needs immediate attention and control.

The Yarrow species can produce an abundance of seeds and is known for its rhizome growth, allowing it to spread quickly within the lawn. Without proper control measures, Yarrow can take over the entire lawn within a few years.

The problem with Yarrow invasion is not only its ability to outcompete other plants, but also its performance in specific conditions. Yarrow is very tolerant to mowing and can continue to grow and spread even after being mown. It also has a high nutrient retention capability, making it more likely to thrive in nutrient-rich lawns.

One of the general ways to control the Yarrow invasion is by using chemical methods. However, these chemicals are often difficult to use without killing other desired plants in the lawn. Additionally, the use of chemicals may raise concerns about its impact on the environment and human health rights.

Another method that is commonly used to control Yarrow is through mechanical means, such as pulling or digging out the plants manually. However, this can be a labor-intensive and time-consuming task, especially if the Yarrow has spread extensively throughout the lawn.

Currently, there is no specific data on the performance of different control methods against Yarrow invasion. It is suggested that a combination of methods, such as chemical and manual control, may be the most effective way to combat this problem. Proper guidelines and instructions are necessary to ensure the correct and safe use of chemicals.

In response to the Yarrow invasion, it is recommended to collect more information on the specific conditions and environment in which Yarrow thrives, as well as the best practices for its control. This information can be gathered from studies, research papers, and websites containing expert advice on lawn care.

While Yarrow is often seen as an unwanted weed in lawns, some people may have a different perspective and find its flowering and medicinal properties appealing. In such cases, a balanced approach should be taken, considering the interests and rights of those individuals while still addressing the Yarrow invasion problem.

In conclusion, the invasion of Yarrow in lawns is a common problem due to its ability to rapidly spread and thrive under specific conditions. It can be controlled by using a combination of manual and chemical methods, but careful consideration should be taken to prevent harm to other desired plants and the environment. Collecting information and following proper guidelines will help address the Yarrow invasion problem effectively and responsibly.


When dealing with an invasion of yarrow in your lawn, there are several solutions you can try to control its growth and maintain the health of your garden. Here are some tips and strategies:

  1. Manual removal: The most basic way to control yarrow is by manually removing it from your lawn. This can be done by digging up the runners and rhizomes using a garden fork or spade. However, be careful to remove the entire plant to prevent its re-growth.
  2. Herbicides: If the invasion is severe and manual removal is not effective, herbicides specifically designed to target yarrow can be used. Make sure to follow the product instructions and use the appropriate type of herbicide for your lawn.
  3. Regular mowing: Mowing your lawn regularly, at the right height and with the proper technique, can help control the growth of yarrow and prevent it from spreading further.

Yarrow has invaded my lawn 460235

Yarrow, or Achillea millefolium, is a species of flowering plant that can be a troublesome weed in lawns. Its invasive nature often leads to its rapid spread, causing it to take over large areas of grass. If you’re dealing with a yarrow invasion in your lawn, here are some tips for controlling and eliminating the problem.

Identifying Yarrow

Yarrow is a perennial plant that can grow up to three feet tall. It has feathery leaves and clusters of small, white flowers. The plant is tolerant of a wide range of growing conditions and can thrive in various types of soil and sunlight conditions.

The Impact of Yarrow Invasion

Yarrow can be particularly difficult to control in lawns because it spreads through both seeds and vegetative means. Its extensive root system allows it to quickly establish itself and compete with turfgrass for nutrients and water. As a result, lawns with a yarrow invasion may become thinner and less vigorous over time.

Controlling Yarrow

There are several methods for controlling yarrow in lawns:

  1. Mowing: Regular mowing can help suppress the growth of yarrow and prevent it from flowering and producing seeds.
  2. Hand-pulling: Small infestations of yarrow can be hand-pulled, but make sure to remove the entire root system to prevent regrowth.
  3. Chemical control: Herbicides containing specific chemicals can be effective in controlling yarrow. However, it’s important to carefully read and follow the instructions on the product label to ensure safe and effective use.
  4. Professional assistance: If the yarrow invasion is severe or persists despite your efforts, consulting a lawn care professional may be necessary. They can provide expert advice and treatments to address the issue.

Preventing Yarrow Invasion

Preventing yarrow from invading your lawn in the first place is the best approach. Here are some preventative measures you can take:

  • Maintain a healthy lawn: A thick, well-maintained lawn is less likely to be invaded by weeds like yarrow. Proper mowing, watering, and fertilization practices can help promote a healthy turfgrass stand.
  • Minimize soil disturbance: Yarrow can take advantage of bare soil areas, so avoid excessive soil disturbance and consider overseeding bare patches to prevent yarrow colonization.
  • Regularly monitor your lawn: By regularly inspecting your lawn for signs of yarrow invasion, you can catch any early infestations and take action before they become a bigger problem.


In conclusion, dealing with a yarrow invasion in your lawn can be challenging, but with the right techniques and preventative measures, you can regain control of your lawn and prevent future invasions. Whether you choose to tackle the problem on your own or seek professional assistance, staying proactive and consistently addressing the issue will yield the best results.
