Sand spurs are a common problem in many yards. They can be a nuisance to walk or play on, and their sharp points can even puncture tires. Luckily, there are several ways to get rid of sand spurs without killing grass.
One way to get rid of sand spurs is to pull them up by hand. This is the most effective method, but it can be time-consuming. To pull sand spurs, simply grasp the plant at the base of the stem and pull it up. Be sure to get the entire root, or the plant may grow back.
Another way to get rid of sand spurs is to use a herbicide. There are several herbicides that are effective against sand spurs, but be sure to choose one that is safe for use on grass. To use a herbicide, simply mix it with water according to the directions on the package and apply it to the affected area. Be sure to follow the directions carefully, as some herbicides can damage grass if they are not used properly.
If you have a large area of sand spurs, you may want to consider using a professional lawn care service. A professional lawn care service will have the experience and equipment to quickly and effectively get rid of sand spurs.
The Perils of Sand Spurs
Sand spurs, also known as caltrops, are the seed burs of various grass species that can be a nuisance in lawns and other areas where people walk barefoot. These burs are characterized by their sharp, pointed spines that can easily penetrate the skin, causing pain and discomfort. Sand spurs can also be dangerous for pets, as they can lodge in their paws or fur and cause irritation and infection.
Sand spurs are most commonly found in sandy or dry areas, but they can also grow in other types of soil. They typically produce burs in the summer and fall, and these burs can remain viable for several years. Sand spurs can spread quickly and easily, as they are dispersed by animals, birds, and even the wind. They can also be transported on shoes and clothing.
The best way to prevent sand spurs is to keep your lawn mowed regularly. This will help to prevent the plants from producing burs. You can also apply pre-emergent herbicides to your lawn in the spring to prevent sand spurs from germinating. If you do find sand spurs in your lawn, you can remove them by hand or with a weed puller. Be sure to wear gloves when handling sand spurs, as their spines can be sharp.
If you are stung by a sand spur, it is important to remove the bur as soon as possible. You can do this by using tweezers to gently pull the bur out of your skin. If the bur is deeply embedded, you may need to see a doctor to have it removed. After removing the bur, clean the area with soap and water and apply an antiseptic. If you experience any pain or swelling, you can take over-the-counter pain medication.
Cultural Practices for Prevention
Implementing proactive measures can help prevent sand spur infestations. These practices include:
1. Maintain Dense Turf
Dense turf creates a barrier, making it difficult for sand spurs to germinate and establish. Mow at the recommended height for your grass species, fertilize regularly, and water deeply and infrequently.
2. Over-seed in Spring and Fall
Over-seeding helps thicken turf and fill bare spots that could become breeding grounds for sand spurs. Choose grass varieties resistant to sand spurs, such as Bermuda, Zoysia, or St. Augustine.
3. Use Mulch or Bark
Spread a layer of mulch or bark around trees and shrubs to create a physical barrier against sand spurs. This also helps retain moisture and suppress weeds.
4. Apply Pre-Emergent Herbicide
Pre-emergent herbicides can prevent sand spur germination. Apply these herbicides according to the manufacturer’s instructions before sand spurs emerge.
5. Proper Mowing and Edging Techniques
Mowing Techniques
Mowing at 3 inches or higher helps prevent bare spots and reduces seed germination. Avoid scalping the lawn, as this creates more opportunities for weeds, including sand spurs.
Edging Techniques
Edging regularly helps to prevent sand spur growth near fences, sidewalks, and other areas where it can easily spread. Use a sharp edger to create a clean, defined edge.
| Mowing Height | Recommended Grass Species |
|---|---|
| 3 inches or higher | Bermuda, Zoysia, St. Augustine |
Preventive Measures for Future Infestations
1. Spread Mulch
It creates a physical barrier, preventing sand spur seeds from reaching the soil and germinating.
2. Water Regularly
Keep the soil moist, making it less conducive for sand spur growth. Well-watered grass is healthier and more resistant to weed invasion.
3. Mow High
Taller grass blades shade the soil and suppress weed growth, including sand spurs.
4. Apply Pre-Emergent Herbicides
Use selective pre-emergent herbicides before sand spur seedlings emerge. Follow label instructions carefully.
5. Limit Foot Traffic
Avoid unnecessary foot traffic in areas where sand spurs are a problem, as their seeds can be spread by human activity.
6. Remove Sand Spurs Regularly
When sand spurs do appear, remove them promptly by hand-pulling or using a weed puller. Dispose of them properly to prevent seed dispersal.
7. Consider Resistant Grass Varieties
Some grass species are more resistant to sand spurs than others. Consult a local nursery for recommendations.
8. Use Sand Spur Control Products
Numerous commercially available products specifically target and control sand spurs. Read and follow label instructions before applying.
9. Maintain Healthy Soil
Healthy soil with a balanced pH and adequate nutrients supports strong grass growth and discourages weed infestations.
10. Encourage Beneficial Insects
Certain insects, such as ladybugs and lacewings, feed on sand spur seeds and young plants. Attract these beneficial insects by providing a suitable habitat, such as blooming flowers and water sources.
