Should I Mow Cheat Grass?

Direct Answer: No, mowing cheat grass is not an effective method of controlling the weed. Repeated mowing every 2 to 3 weeks during spring and summer may provide some control, but it will not prevent seed production. In fact, cheat grass can quickly regrow and produce seed after mowing.

Why Mowing is Not Effective

Cheat grass is a highly invasive weed that can outcompete native grasses and plants. It has a rapid growth rate, which allows it to quickly respond to mowing. Moreover, cheat grass has a deep root system, making it difficult to kill with a single mowing.

Drawbacks of Mowing Cheat Grass

• Increases seed production: Mowing cheat grass can actually stimulate seed production, as the plant focuses its energy on producing seeds rather than leaves.
• Encourages regrowth: Cheat grass can regrow from small pieces of stem left behind after mowing, making it difficult to eradicate.
• Can spread disease: Mowing can spread diseases from infected cheat grass to other plants in the area.

Alternative Methods of Control

Instead of mowing, consider the following alternative methods of controlling cheat grass:

• Tillage: Use a deep tillage to disrupt the soil and prevent seed germination.
• Herbicides: Apply selective herbicides that target cheat grass without harming other plants.
• Grazing: Use livestock to graze the area and prevent cheat grass from seed production.
• Cover Cropping: Plant a cover crop that competes with cheat grass for water and nutrients.

When to Mow Cheat Grass

If you still want to mow cheat grass, consider the following:

• Mow in early spring: Mow cheat grass in early spring when it is still young and has not yet produced seeds.
• Mow regularly: Mow regularly, every 2 to 3 weeks, to prevent seed production.
• Mow at the correct height: Mow at a height of 6-8 inches to reduce seed production.

Additional Tips

• Use a weed trimmer: Use a weed trimmer to cut cheat grass stems, rather than a lawnmower, to reduce the risk of spreading disease.
• Remove seedheads: Remove seedheads after mowing to prevent seed production.
• Improve soil health: Improve soil health by adding organic matter and reducing soil disturbance to prevent cheat grass invasion.

Conclusion

In conclusion, mowing cheat grass is not an effective method of controlling the weed. Instead, consider alternative methods such as tillage, herbicides, grazing, and cover cropping. If you still want to mow, make sure to mow in early spring, regularly, and at the correct height. Additionally, use a weed trimmer, remove seedheads, and improve soil health to reduce the spread of cheat grass.
