Cheat grass, also known as downy brome, is an invasive species that poses a significant challenge to landowners, gardeners, and farmers alike. Its ability to spread rapidly and outcompete native vegetation makes it a persistent nuisance in many regions.

Controlling cheat grass requires a strategic and persistent approach that combines both preventative measures and active management techniques.

In this article, I will explore effective methods for getting rid of cheatgrass and reclaiming your land from its invasive grasp.

The first step in combating cheat grass is understanding its life cycle and preferred habitat.

Cheatgrass typically thrives in disturbed areas with poor soil conditions, making it especially prevalent in fields, pastures, and along roadsides.

To prevent its spread, land managers should focus on maintaining healthy ecosystems and minimizing disturbances that create ideal conditions for cheatgrass to take hold.

For existing cheatgrass infestations, a combination of mechanical, chemical, and biological control methods may be necessary.

Mechanical methods like mowing or tilling can help reduce cheatgrass populations, especially when combined with timely herbicide applications targeting the plant’s growth stages.

Additionally, introducing competitive native vegetation and promoting biodiversity can help suppress cheat grass growth and restore balance to affected ecosystems.

By employing a multifaceted approach tailored to specific environmental conditions, landowners can effectively combat cheat grass and reclaim their land for native species and sustainable land use practices.

So, how do you get rid of cheatgrass from your pasture?

Short Answer

You get rid of cheatgrass by mowing or tilling to disrupt its growth cycle and applying targeted herbicide during key growth stages. In addition, you can introduce competitive native vegetation to outcompete cheatgrass and minimize soil disturbance to prevent its spread.

Simple Strategies on How to Get Rid of Cheatgrass in Pasture

Cheatgrass is an invasive species that can quickly take over landscapes, crowding out native plants and increasing the risk of wildfires. For these and other reasons, let’s now talk about how to get rid of cheatgrass.

Understand Cheat Grass

The first step in eliminating cheatgrass starts with understanding how it grows.

Cheatgrass thrives in disturbed areas with poor soil conditions, making it prevalent in fields, pastures, and along roadsides.

The grass germinates early in the season, typically in fall or early spring, and quickly establishes itself, outcompeting native vegetation. Its ability to produce prolific seeds further exacerbates its spread.

Take Preventive Measures

Preventing cheat grass from establishing itself in the first place is key to effective control.

You can do this by maintaining healthy ecosystems by minimizing disturbances that create ideal conditions for cheat grass to take hold.

Deliberate steps include:

  • Reducing soil disturbance during construction or farming activities
  • Minimizing overgrazing
  • Practicing responsible land management techniques

Employ Mechanical Control Measures

Mechanical methods can be effective in reducing cheatgrass populations, especially in smaller areas or localized infestations.

Mowing or weed-whacking can help to disrupt the growth cycle of cheat grass, preventing it from producing seeds and spreading further.

But even as you think of mowing, timing is crucial. You need to mow cheat grass before it goes to seed to prevent further spread.

However, mechanical methods alone may not be sufficient for large-scale infestations or areas with dense growth.

Use the Chemical Control Approach

How to Get Rid of Cheat Grass

Herbicides can be an effective tool for controlling cheat grass, especially in larger infestations or where mechanical methods are impractical.

Selective herbicides targeting grassy weeds can help to suppress cheat grass while minimizing harm to desirable plants.

For best results, use RoundUp Pro Max (pictured ) before cheatgrass forms seed heads and follow application instructions carefully to ensure effectiveness and minimize environmental impact.

It is also crucial to consult with a professional or local extension office for guidance on herbicide selection and application techniques tailored to your specific situation.

Opt for Biological Control

In some cases, biological control methods can complement mechanical and chemical approaches to manage cheatgrass infestations.

Introducing grazing animals such as goats or sheep can help to reduce cheatgrass populations by grazing on the plants.

Additionally, exploring biological control agents such as fungal pathogens or insects that specifically target cheat grass can offer long-term suppression benefits.

However, you need to assess potential risks and consult with experts before introducing biological control agents to ensure they won’t harm native vegetation or ecosystems.

Long-Term Management

Getting rid of cheatgrass requires ongoing monitoring and management efforts to prevent re-infestation and promote ecosystem health.

Regularly inspect your property for signs of cheatgrass growth and take proactive measures to address any new infestations promptly.

Implement practices that promote soil health, such as reducing soil compaction and improving water infiltration, to create conditions favorable for native vegetation to thrive.

5 Reasons Why You Should Remove Cheatgrass

Removing cheatgrass is essential for several reasons, including:

1. Fire Hazard

Cheatgrass is highly flammable and increases the risk of wildfires. Its dry, fine fuels can ignite easily and spread rapidly, especially in arid and semi-arid regions.

Once ignited, cheatgrass-fueled fires can escalate quickly, threatening human lives, property, and natural habitats.

2. Ecological Disruption

Cheatgrass outcompetes native vegetation for resources such as water, nutrients, and sunlight. Its aggressive growth can displace native plant species, disrupting ecological balance and reducing biodiversity.

This disruption can negatively impact wildlife habitats and reduce forage availability for grazing animals.

3. Economic Impact

Cheatgrass infestations can have significant economic consequences for landowners, farmers, and ranchers.

The grass reduces crop yields, diminishes forage quality for livestock, and increases management costs associated with controlling its spread.

Invasive species like cheatgrass can also affect recreational activities such as hiking, hunting, and camping, impacting local economies dependent on tourism.

4. Soil Erosion

Cheatgrass forms dense mats that can stabilize soil surfaces, increasing the risk of soil erosion.

Its shallow root system does not provide sufficient soil stabilization, especially in areas prone to erosion.

Soil erosion can lead to loss of fertile topsoil, decreased water quality in nearby water bodies, and degradation of overall soil health.

5. Altered Ecosystem Dynamics

When left to grow, cheatgrass alters ecosystem dynamics by changing fire regimes, nutrient cycling, and hydrological processes. Its dominance can create feedback loops that perpetuate its spread while hindering the recovery of native plant communities.

Restoring cheatgrass-infested areas to their natural state can be challenging and costly due to the altered ecological processes.

How to Get Rid of Cheat Grass FAQs

Q: What is the best time to control cheatgrass?

A: Controlling cheatgrass is most effective when undertaken during its active growth phases, typically in the fall and early spring. During these periods, cheatgrass is more susceptible to control measures such as herbicide applications or mechanical removal. It’s crucial to target cheatgrass before it goes to seed to prevent further spread and re-infestation.

Q: Can grazing animals help control cheatgrass?

A: Grazing animals such as goats, sheep, and cattle can help reduce cheatgrass populations by consuming its tender shoots and preventing seed production. However, the effectiveness of grazing as a control method depends on factors such as stocking density, timing, and duration of grazing. Proper management practices, including rotational grazing and monitoring grazing pressure, are necessary to prevent overgrazing and promote desirable plant species.

Q: What are the long-term management strategies for controlling cheatgrass?

A: Long-term management of cheatgrass requires a combination of approaches tailored to specific environmental conditions and land use goals. Implementing practices that promote soil health, such as reducing soil disturbance and improving water infiltration, can create conditions less favorable for cheatgrass establishment. Introducing competitive native vegetation and restoring ecosystem function can help suppress cheatgrass growth and prevent re-infestation. Regular monitoring and adaptive management are essential to assess the effectiveness of control measures and adjust strategies as needed over time.


In conclusion, effectively getting rid of cheatgrass requires a multifaceted approach that combines preventive measures, active management techniques, and long-term strategies.
