Grass burrs, also known as stickers or sand spurs, are the seeds of the grass burr plant, which can be a nuisance for many homeowners. These small, prickly seeds can stick to your clothes, skin, and pets, causing discomfort and pain. Moreover, they can also harm your lawn by competing with the grass for water, nutrients, and light. If you’re looking for ways to kill grass burrs without harming your grass, you’ve come to the right place. In this article, we’ll explore the different methods you can use to control and eliminate grass burrs from your lawn.
Understanding Grass Burrs
Before we dive into the methods of killing grass burrs, it’s essential to understand what they are and how they grow. Grass burrs are the seeds of the Cenchrus echinatus plant, a type of grassy weed that thrives in warm, dry climates. The seeds are designed to stick to animals and clothing, allowing them to spread to new areas. The seeds can germinate and grow into new plants, producing more seeds and continuing the cycle. To break this cycle, you need to target the seeds and the plant itself.
Life Cycle of Grass Burrs
The life cycle of grass burrs consists of three stages: seed, seedling, and mature plant. The seeds germinate in the spring and early summer, producing seedlings that grow into mature plants. The mature plants produce flowers and seeds, which can disperse and spread to new areas. Understanding the life cycle of grass burrs is crucial in determining the best method of control. By targeting the seeds and seedlings, you can prevent the plants from producing more seeds and spreading.
Types of Grass Burrs
There are several types of grass burrs, including field sandbur, southern sandbur, and longspine sandbur. Each type has slightly different characteristics and growth habits, but they all produce seeds that can stick to clothing and skin. Identifying the type of grass burr you’re dealing with can help you choose the most effective method of control.
<h2_Methods of Killing Grass Burrs
There are several methods you can use to kill grass burrs without harming your grass. These methods include:
Physical Removal
One of the most effective methods of killing grass burrs is physical removal. This involves manually pulling or digging up the plants, making sure to remove the entire root system. This method is most effective when the plants are young and the soil is moist. You can use a tool like a hoe or a weeding fork to remove the plants, making sure to wear protective clothing and gloves to avoid getting stuck by the seeds.
Chemical Control
Another method of killing grass burrs is chemical control. This involves using herbicides to kill the plants and prevent them from producing seeds. However, chemical control can be risky, as it can also harm your grass and other plants. It’s essential to choose a herbicide that is specifically designed for grass burrs and follow the instructions carefully to avoid damaging your lawn.
Cultural Control
Cultural control involves modifying your lawn care practices to make your lawn less conducive to grass burrs. This includes maintaining a healthy, dense lawn through proper mowing, watering, and fertilization. A healthy lawn can compete with grass burrs for water, nutrients, and light, making it more difficult for them to grow. You can also use mulch or other groundcovers to suppress grass burr growth.
<h2_Prevention is the Best Method
While there are several methods you can use to kill grass burrs, prevention is the best method. By taking steps to prevent grass burrs from growing in the first place, you can avoid the hassle and expense of trying to control them. Here are a few tips for preventing grass burrs:
Improve Soil Quality
Grass burrs thrive in poor soil conditions, so improving soil quality can help prevent them from growing.

You can also test your soil to determine its pH level and nutrient content, making adjustments as needed.
Mow High
Mowing your lawn at a higher height can help prevent grass burrs from growing. Taller grass can shade out grass burr seeds, preventing them from germinating. It’s recommended to mow your lawn at a height of at least 2.5 inches to prevent grass burrs from growing.
Water Deeply
Grass burrs prefer dry soil conditions, so watering your lawn deeply can help prevent them from growing. Watering deeply but infrequently can encourage deep root growth, making your lawn more resistant to grass burrs. It’s recommended to water your lawn for longer periods of time, but less frequently, to encourage deep root growth.
Additional Tips
In addition to the methods mentioned above, here are a few additional tips for killing grass burrs without harming your grass:
Use a Pre-Emergent Herbicide
A pre-emergent herbicide can help prevent grass burr seeds from germinating. These herbicides create a barrier on the soil surface that prevents seeds from growing. They are typically applied in the early spring, before the seeds germinate.
Use a Post-Emergent Herbicide
A post-emergent herbicide can help kill grass burrs that have already germinated. These herbicides are typically applied directly to the plants, and can be more targeted than pre-emergent herbicides. However, they can also be more risky, as they can harm your grass and other plants if not used properly.
