Understanding the Enemy: What Are Sand Spurs?
Before we jump into the “how,” we need to understand the “what.” Sand spurs, often called sandburs or grass burrs, are actually a type of annual or perennial grass from the Cenchrus genus. They thrive in sandy, nutrient-poor soil where other grasses struggle to survive.
The part we hate most is the seed pod, which is covered in stiff, barbed spines. These barbs are designed by nature to hook onto passing animals or humans to spread their seeds across your entire property. If you see one spur, there are likely hundreds of seeds waiting to germinate nearby.
These plants are opportunistic. They don’t just appear by accident; they move in when your turf is weak or stressed. By understanding their life cycle, you can hit them when they are most vulnerable, usually in the early spring or late fall.
The Manual Method: how to get rid of sand spurs in your lawn Without Chemicals
If you have a small infestation, the most effective way to start is by getting your hands a little dirty. Manual removal is labor-intensive, but it provides immediate results and prevents further seed spread. You just need to make sure you have a thick pair of gardening gloves before you start.
When pulling these weeds, it is vital to remove the entire root system. Sand spurs can often grow back from the base if the crown is left intact. Use a small hand trowel or a weeding tool to loosen the soil around the base before lifting the plant upward.
One “pro tip” I always recommend is the blanket trick. Drag an old piece of fuzzy carpet or a heavy wool blanket over the infested area. The spurs will latch onto the fabric, allowing you to “harvest” thousands of seeds at once. Just be sure to bag and dispose of the fabric afterward!
Bagging Your Grass Clippings
If you usually mulch your grass, you need to stop while dealing with an infestation. Mulching returns the seeds directly to the soil, ensuring a new crop of spurs next season. Always use a bagging attachment on your mower during the summer months.
Set your mower height a bit higher than usual. While it might seem tempting to “scalp” the weeds, this actually stresses your good grass and gives the spurs more sunlight to thrive. A taller lawn shades the soil and prevents new seeds from getting the light they need to sprout.
Dispose of your clippings in a dedicated waste bin. Never add sand spur clippings to your home compost pile. Most backyard compost bins do not reach the high temperatures required to kill the resilient seeds of the Cenchrus plant.
Using Pre-Emergent Herbicides for Long-Term Control
The most effective strategy for how to get rid of sand spurs in your lawn involves stopping them before they even break the surface. This is where pre-emergent herbicides come into play. These products create a chemical barrier in the soil that prevents seeds from developing roots.
Timing is everything when using a pre-emergent. You must apply the product in early spring, specifically when the soil temperature consistently reaches 52 degrees Fahrenheit. For many gardeners, this coincides with the blooming of Forsythia bushes or the first signs of spring green-up.
If you wait until you see the green shoots of the spurs, the pre-emergent will not work. These chemicals do not kill existing plants; they only stop new ones from starting. A second application in late spring can help catch any late-blooming seeds that missed the first round.
Choosing the Right Product
Look for products containing active ingredients like Pendimethalin or Oryzalin. These are specifically formulated to target grassy weeds like sandburs without harming your established lawn. Always read the label to ensure the product is safe for your specific grass type.
For example, some herbicides are safe for Bermuda grass but can be devastating to St. Augustine or Centipede grass. If you are unsure about your grass type, take a small plug to your local nursery for identification before applying any chemicals.
After applying the granules or spray, you usually need to “water it in.” A light watering helps the chemical move down into the top inch of soil where the seeds are waiting. Without water, the herbicide may just sit on the surface and break down in the sunlight.
Post-Emergent Solutions: When the Spurs Are Already There
If you missed the window for pre-emergents, don’t panic. You can still use post-emergent herbicides to kill the plants that have already sprouted. The key is to catch them while they are young and tender, before they have a chance to produce those painful seed heads.
Look for a herbicide that contains Quinclorac or MSMA (where legal). These ingredients are highly effective against grassy weeds. However, be aware that these can be “hot” chemicals, meaning they can stress your lawn if applied during extreme heat or drought conditions.
Knowing how to get rid of sand spurs in your lawn with post-emergents requires precision. Use a “spot treatment” approach whenever possible. Instead of spraying your entire yard, target only the areas where you see the spurs growing to minimize the chemical footprint on your turf.
Natural and Organic Alternatives
If you prefer to avoid synthetic chemicals, there are organic options available. Horticultural vinegar (20% acetic acid) can kill young sand spurs on contact. Be careful, though, as this is a non-selective herbicide and will kill any green plant it touches, including your grass.
Corn gluten meal is another popular organic pre-emergent. While it is not as powerful as synthetic versions, it can inhibit seed germination over time while providing a small boost of nitrogen to your lawn. It takes several seasons of consistent use to see significant results with corn gluten.
For a truly manual organic approach, focus on soil solarization. In extreme cases, you can cover a heavily infested patch with clear plastic during the hottest part of the summer. The heat trapped underneath will effectively “cook” the seeds and the plants, though you will have to re-sod the area afterward.
Improving Soil Health to Prevent Re-Infestation
The absolute best way for how to get rid of sand spurs in your lawn is to make your lawn a place where they don’t want to live. Sand spurs are “pioneer weeds.” They thrive in dry, sandy, and acidic soil that lacks essential nutrients. If your lawn is healthy, it will naturally choke out the weeds.
Start with a soil test. Most local university extension offices offer low-cost soil testing kits. This test will tell you exactly what your soil is missing. Often, adding lime to raise the pH level or adding organic compost to improve water retention is all it takes to shift the balance in favor of your grass.
Sand spurs hate competition. By fertilizing your lawn on a regular schedule, you encourage your desirable grass to grow thick and deep. A dense root system leaves no room for sand spur seeds to find a foothold in the soil. Think of your grass as a living shield.
The Role of Irrigation
Since sand spurs love dry conditions, proper irrigation is a powerful tool. Instead of light, daily watering, aim for deep, infrequent watering. This encourages your grass roots to grow deep into the earth, making them more resilient to drought than the shallow-rooted sand spurs.
Watering early in the morning is best. This allows the grass blades to dry out during the day, preventing fungal diseases, while ensuring the roots get the moisture they need. A lawn that is never stressed by thirst is a lawn that can successfully fight off weed invasions.
If you have patches of bare sand, consider planting a groundcover or adding more sod. Bare dirt is an open invitation for wind-blown seeds. Covering those spots immediately removes the opportunity for the spurs to establish a new colony.
Safety Considerations for Kids and Pets
When you are working on how to get rid of sand spurs in your lawn, safety should be your top priority. The barbs on these seeds are not just painful; they can cause infections or allergic reactions in sensitive individuals. Always keep children and pets away from infested areas until the problem is under control.
Check your pet’s paws and fur every time they come inside. Sand spurs can easily get lodged between their toes, leading to limping or skin irritation. Use a pair of tweezers to gently remove any spurs you find, and keep the area clean to prevent infection.
If you are using chemical herbicides, strictly follow the “re-entry” interval listed on the label. Usually, this means keeping everyone off the grass until the product has completely dried or been watered in. Safety first ensures that your journey to a beautiful lawn is a happy one.
Frequently Asked Questions About Sand Spurs
Can I just mow sand spurs to kill them?
No, mowing will not kill sand spurs. In fact, they are very adaptable and will start producing seed heads closer to the ground if they are frequently mown. Mowing without a bagger will actually spread the seeds further across your lawn.
Will sand spurs go away on their own in the winter?
While the green plant may die back in a hard freeze, the seeds are incredibly hardy. They can lay dormant in the soil for several years, waiting for the right temperature to sprout again. You must take active steps to remove the seeds to stop the cycle.
Is there a grass type that is resistant to sand spurs?
No grass is completely “immune,” but thick, aggressive grasses like Bermuda or Zoysia are excellent at out-competing weeds. The key is maintaining the health of whatever grass you have so it stays dense enough to block out the spurs.
Can I use salt to kill sand spurs?
I strongly advise against using salt in your yard. Salt ruins the soil structure and prevents anything from growing for a long time. It can also leach into the groundwater. Stick to targeted herbicides or manual removal for better long-term results.
