If you’re planning a landscaping project and thinking about laying down fabric, you’ve probably asked yourself: Will landscaping fabric kill grass?
The short answer: It can—but not always completely, and not instantly. Below, we’ll break down how it works, what to expect, and the best way to use it if you want long-term results.
✅ What Is Landscaping Fabric?
Landscaping fabric (also called weed barrier or landscape cloth) is a woven or non-woven material used to suppress weed growth and reduce soil erosion. It’s commonly installed under mulch, rock, or gravel in flower beds and garden areas.
🌱 Will It Actually Kill the Grass?
Yes, landscaping fabric can kill grass—but it depends on how it’s used.
- By itself: Laying fabric directly over grass may suffocate it over time by blocking sunlight and air. But many grasses are resilient and can find ways to grow around or even through the fabric over time.
- With mulch or stone on top: This increases the likelihood of grass dying off, since the weight and lack of light will smother the grass more effectively.
- Over time: Expect grass to take several weeks (or even months) to fully die under fabric unless additional steps are taken.
⚠️ Common Mistakes to Avoid
- Not cutting or scalping the grass first: Long grass will create air pockets under the fabric, slowing the smothering process.
- Skipping edge sealing: Grass can creep in from the edges if the fabric isn’t properly secured.
- Using it in the wrong places: Landscaping fabric is better suited for non-planting areas (under rocks, gravel paths, etc.). In plant beds, it can restrict water and nutrient flow to your plants.
💡 What Works Better?
If your goal is to fully eliminate grass in an area you’re landscaping, here are better approaches:
- Remove the grass manually (sod cutter or shovel)
- Use a non-toxic grass killer (vinegar or herbicide, depending on preference)
- Cover with cardboard or layers of newspaper + mulch (eco-friendly alternative to fabric)
- Till the area and amend soil before planting
📍 Local Tip for Alexandria, LA:
Many yards in Central Louisiana use St. Augustine or Bermuda grass—both are tough to kill. Using only landscape fabric will rarely be enough for a clean, grass-free space.
👍 Final Verdict
Landscaping fabric can kill grass, but it’s not a magic solution.
For best results, use it with mulch or rocks and consider removing grass beforehand for a truly clean slate.
