Sandbur Weed: How to Get Rid of It in Your Yard
Do you have sandbur weed growing in your yard or garden? If so, you’re probably wondering how to get rid of it. Sandbur weed is a common lawn weed that can be quite difficult to control. In this article, we’ll go over everything you need to know about sandbur weed and how to get rid of it for good.
What Is Sandbur Weed?
Sandbur weed (Cenchrus echinatus) is an annual grassy weed that is common in sandy soil in the southern United States. It grows in a clump form and can be recognized by its spiny fruiting heads, which are about the size of a marble.
The fruiting heads contain spiky burrs that stick to clothing, fur, and skin. Because of this, sandbur weed is often called “stickers” or “prickly sandbur.”
What Causes Sandbur Weed?
Sandbur weed thrives in sandy soil with low fertility. Overgrazing, minimal irrigation, and soil compaction also promote the growth of sandbur weed.
- Overgrazing: Excessive grazing can lead to bare patches in the soil, which sandbur weed loves.
- Minimal irrigation: Sandy soil doesn’t retain water well, and this can make it difficult to keep your lawn or garden well-watered.
- Soil compaction: Compacted soil makes it difficult for plants to get the nutrients they need, which can contribute to the growth of weeds like sandbur.
Identifying Sandbur Weed
If you’re not sure whether you have sandbur weed or not, look for the following characteristics:
- Clumped grassy weed with fibrous roots.
- Fruit heads that are spiny and covered in burrs.
- Seed heads that contain multiple burrs.
When Does Sandbur Weed Grow?
Sandbur weed starts to grow in the spring and summer, and it can continue to grow until the first frost in the fall. The plant produces seeds throughout the growing season, so it’s important to control it as early as possible.
How to Control Sandbur Weed
There are several methods for controlling sandbur weed, and the best method for you will depend on the severity of your infestation and your personal preferences.
1. Mow Your Lawn Regularly
Mowing your lawn regularly will help keep sandbur weed from producing seed heads and spreading. Mow your lawn to a height of 2-3 inches and be sure to bag the clippings to prevent seeds from being spread around.
2. Use Pre-emergent Herbicides
Pre-emergent herbicides can be effective in controlling sandbur weed. These herbicides work by preventing the weed seeds from germinating. Apply the herbicide in the spring or early summer, before seed germination occurs.

If you only have a few sandbur weeds, you can try hand-pulling them. Be sure to wear gloves before pulling, and try to remove the entire plant, including the roots and seed heads.
4. Use Post-emergent Herbicides
Post-emergent herbicides are designed to kill weeds that have already germinated. If you have a large infestation of sandbur weed, a post-emergent herbicide may be your best option.
Types of Post-emergent Herbicides
There are several different types of post-emergent herbicides available, and some are more effective than others. Some of the most commonly used herbicides for controlling sandbur weed include:
5. Improve Soil Quality
