Understanding the Enemy: What Are Sand Spurs?
Before we dive into the removal process, it is helpful to understand what we are actually fighting. Sand spurs, often called sandburs or stickers, belong to the Cenchrus genus of grasses.
These are not just random weeds; they are actually annual or perennial grasses that produce those painful, seed-bearing burrs. These burrs are designed by nature to latch onto fur, clothing, and skin to spread their seeds far and wide.
In my experience, they thrive in specific conditions that other grasses hate. If your lawn is struggling with sandy soil, low nutrients, or extreme heat, sand spurs will see it as an invitation to move in.
They are incredibly resilient because each burr can contain multiple seeds. Even if you kill the plant, those seeds can remain dormant in the soil for years, waiting for the right moment to sprout.
That is why a one-time treatment usually is not enough. To truly win this battle, we need to address both the living plants and the seed bank hiding beneath the surface of your soil.
The Ultimate Step-by-Step Guide: how to get rid of sand spurs in grass
If you want to know how to get rid of sand spurs in grass effectively, you have to use a multi-pronged approach. You cannot simply spray a chemical and expect them to vanish forever without changing your lawn care habits.
The first thing I always recommend is a thorough inspection of your yard to see how widespread the infestation is. If you only have a few patches, manual removal is your best friend and the most environmentally friendly option.
For larger areas, we have to look at pre-emergent and post-emergent strategies. This means stopping new seeds from growing in the spring and killing the active plants during the summer months.
I have found that timing is the most critical factor in this process. If you miss the window for pre-emergent application, you will be playing catch-up for the rest of the growing season.
Let’s break down the specific mechanical, chemical, and cultural methods you can use right now to start seeing results in your turf.
Mechanical Removal: The “Old Blanket” Trick
One of my favorite “pro tips” for dealing with active burrs is what I call the blanket drag. This is a simple but highly effective way to collect seeds before they fall into the soil.
Find an old piece of fleece or a fuzzy wool blanket that you no longer need. Attach it to the back of your riding mower or simply drag it across the infested areas of your lawn.
The hooks on the sand spurs will naturally latch onto the fabric. Once the blanket is covered in burrs, you can carefully fold it up and dispose of it in the trash—never in your compost pile!
This method significantly reduces the number of seeds that will sprout next year. It is a great way to clear a path for kids or dogs to play without getting poked.
Hand-Pulling and Proper Disposal
For small clusters, nothing beats getting your hands dirty. However, you must wear thick leather gloves because those spines can easily penetrate thin gardening gloves.
When you pull the plants, try to get as much of the root system as possible. These weeds often grow in a low, spreading habit, so you might need to lift the “legs” of the plant to find the central root.
Always carry a bucket with you so you can drop the plants directly inside. If you leave a pulled plant on the lawn, the burrs can still dry out and drop their seeds into the thatch layer.
I strongly advise against putting these weeds in your green waste bin if your local facility uses low-heat composting. The seeds are tough and can survive many standard composting processes.
Using Pre-Emergent Herbicides for Long-Term Control
The secret to a sand-spur-free lawn is preventing the seeds from ever germinating. This is where pre-emergent herbicides come into play, and they are a game-changer for any gardener.
These products create a chemical barrier at the soil surface. When the sand spur seed tries to send out its first root, the herbicide stops the process, and the weed dies before you ever see it.
The most important factor here is soil temperature. Sand spurs typically begin to germinate when the soil temperature consistently reaches 55 degrees Fahrenheit (about 13 degrees Celsius).
In many southern regions, this happens as early as late February or early March. If you wait until you see the grass growing, you have already missed the most effective time to apply your treatment.
Look for products containing active ingredients like Pendimethalin or Oryzalin. These are specifically formulated to target grassy weeds like sandburs and crabgrass without harming your established lawn.
Always water the product in immediately after application. This helps the chemical move down into the top inch of soil where the weed seeds are sitting, ensuring the barrier is properly set.
Post-Emergent Solutions for Active Infestations
If you already have green sand spur plants growing in your yard, a pre-emergent won’t help you. You will need a post-emergent herbicide designed for “grassy weed” control.
This can be tricky because sand spurs are a type of grass. You need a product that can distinguish between your “good” grass (like Bermuda or St. Augustine) and the “bad” sand spur grass.
I often suggest looking for herbicides containing Quinclorac. This chemical is very effective against young sand spurs, especially when they are in the early growth stages before they produce burrs.
If you have a Bermuda grass lawn, you have more options, as Bermuda is quite hardy. However, if you have Centipede or St. Augustine grass, you must be very careful, as many herbicides will kill these turf types too.
Always read the label twice. The label is the law, and it will tell you exactly which grass types the product is safe for and what the maximum temperature for application should be.
Applying herbicides when it is over 90 degrees Fahrenheit can cause phytotoxicity. This is when the chemical stresses your lawn grass so much that it turns yellow or dies along with the weeds.
Cultivating a Healthy Lawn to Crowd Out Weeds
The best defense against any weed is a thick, lush carpet of healthy grass. Sand spurs are opportunistic; they only move in when there is bare soil or thinning turf to exploit.
If your lawn is dense and healthy, the weed seeds won’t be able to get the sunlight or space they need to grow. This is why I always tell my friends that “lawn health is weed wealth.”
Start by performing a soil test. You can get these kits from your local university extension office. Sand spurs love acidic soil with low nitrogen, so you may need to add lime or fertilizer.
By adjusting your soil pH to a more neutral range (6.5 to 7.0), you make the environment much more favorable for your desired grass and less hospitable for the sandburs.
Proper mowing is also essential. Never remove more than one-third of the grass blade at a time. Keeping your grass slightly taller provides shade to the soil, which prevents weed seeds from waking up.
The Importance of Deep Watering
Many people make the mistake of watering their lawn lightly every single day. This actually encourages shallow root systems and creates a perfect environment for sand spurs.
Instead, you should aim for deep, infrequent watering. Give your lawn about an inch of water once or twice a week. This encourages your grass roots to grow deep into the earth.
Sand spurs have relatively shallow roots. When the surface of the soil dries out between waterings, the weeds struggle, while your deep-rooted grass continues to thrive and dominate the space.
Aeration and Overseeding
If your soil is compacted, your grass will struggle to grow, leaving gaps for stickers to fill. Core aeration pulls small plugs of soil out of the ground, allowing air and water to reach the roots.
After aerating, it is the perfect time to overseed. By spreading fresh grass seed into those holes, you are actively filling in the gaps that sand spurs would otherwise occupy.
I recommend doing this in the fall for cool-season grasses or late spring for warm-season grasses. It is a long-term investment that pays off in a much more resilient and beautiful lawn.
Safe Gardening: Protecting Yourself and Your Pets
While we focus on how to get rid of sand spurs in grass, we must also think about safety. These burrs are not just annoying; they can cause infections if they break off under the skin.
If you have pets, check their paws every time they come inside. Sand spurs can get lodged between their pads, leading to limping and significant discomfort for your furry friends.
When using herbicides, always keep children and pets off the treated area until the product has completely dried. This is usually about 24 hours, but check the specific product instructions.
If you are dealing with a massive infestation that seems out of control, do not be afraid to call in a professional lawn care service. Sometimes, industrial-grade equipment is needed for the first “reset.”
Professional technicians have access to specialized chemicals that are not always available to the general public. They can help you get the situation under control so you can take over the maintenance later.
Frequently Asked Questions About how to get rid of sand spurs in grass
Will vinegar kill sand spurs?
Vinegar can kill the green, leafy parts of a sand spur plant, especially if you use high-strength horticultural vinegar. However, it is a non-selective herbicide, meaning it will also kill your grass.
It also rarely kills the seeds inside the burrs. I only recommend using vinegar for spot-treating sand spurs in driveways or cracks in the sidewalk where you don’t care about the surrounding vegetation.
How long do sand spur seeds last in the soil?
Unfortunately, sand spur seeds are very hardy. They can remain viable in the soil seed bank for three to five years. This is why consistent prevention is so important for long-term success.
Even if you don’t see any plants this year, you should continue applying pre-emergent for a few seasons to ensure you have exhausted the supply of old seeds hiding underground.
Can I just mow over sand spurs to get rid of them?
Mowing can actually make the problem worse if you aren’t careful. If the plants have already produced burrs, the mower will simply spread the seeds across the rest of your yard.
If you must mow an infested area, always use a bagging attachment. Dispose of the clippings in the trash to ensure you are removing the seeds from your property entirely.
Why do sand spurs keep coming back to my yard?
They usually return because the underlying soil conditions haven’t changed. If your soil remains sandy, dry, and nutrient-poor, it will always be a magnet for these specific types of weeds.
Focus on enriching your soil with organic matter and maintaining proper moisture levels. Once the environment changes, the sand spurs will find it much harder to compete with your grass.
Final Thoughts on Reclaiming Your Lawn
Getting rid of stickers is a marathon, not a sprint. It takes patience, the right timing, and a bit of “elbow grease” to finally clear them out, but I know you can do it!
Remember that the most effective strategy on how to get rid of sand spurs in grass involves preventing new growth in the spring and improving your lawn’s health year-round.
Don’t be discouraged if you see a few pop up after your first treatment. Just keep pulling them, keep feeding your grass, and stay consistent with your pre-emergent applications.
Your reward will be a soft, green lawn where you can walk barefoot and play with your pets without a care in the world. You have the tools and the knowledge now, so go forth and grow a better garden!
