Eliminating Grass Burs from Your Centipede Lawn

Dealing with a yard full of grass burs—also known as sand spurs—can turn a simple walk across the lawn into a painful ordeal. If you're in East Texas with a centipede grass lawn that's been overtaken by these prickly invaders, you're not alone. The good news is that with the right timing and products, you can reclaim your turf.

Prevention Is the Best Cure

The most effective defense against sand spurs is a thick, healthy lawn that naturally crowds out weeds. Since you're entering the prime window for pre-emergent herbicide applications, now is the time to act. In Texas, soil temperatures typically reach 52°F sometime in March or April, signaling the start of the application season.

Choosing the Right Pre-Emergent

Several pre-emergent herbicides are compatible with centipede grass and can stop sand spur seedlings before they emerge:

• Surflan
• Pre-M
• Amaze (Green Light)
• Weed & Grass Preventer
• Weed Stopper

Apply your chosen product every six weeks through September to maintain a protective barrier. Always verify the label confirms compatibility with centipede grass before purchasing.

Post-Emergent Options for Existing Burs

If sand spurs have already sprouted, post-emergent herbicides containing MSMA or DSMA can help. However, DSMA cannot be used on centipede or St. Augustine lawns, so stick with MSMA-based products for your grass type.

Cultural Practices for Long-Term Control

Beyond herbicides, focus on revitalizing your lawn to create dense turf coverage. Mow at the proper height for centipede grass (typically 1.5 to 2 inches) to prevent weeds from outgrowing the grass and going to seed. Consistent watering, fertilization based on soil test results, and aeration when needed will strengthen your lawn's natural competitiveness.

With a combination of timely pre-emergent applications, targeted post-emergent treatment, and good cultural practices, you can transform that "land mine field" back into a comfortable, barefoot-friendly lawn.
