Landscape fabric can be a powerful ally in your war against weeds. It’s a tried-and-true method used by gardeners and landscapers to reduce unwanted plant growth while promoting a clean, low-maintenance yard or garden bed. But like all good things in the garden, landscape fabric requires a little ongoing attention to stay effective — and eventually, it may need replacing.
In this post, we’ll dive deep into how to maintain your landscape fabric over the years, extend its lifespan, and recognize the telltale signs that it’s time to replace it.

Why Use Landscape Fabric?

Before we talk about maintenance, it’s worth briefly reviewing why people use landscape fabric in the first place:
- Weed suppression: The primary benefit is preventing weeds from growing while still allowing water and nutrients to pass through.
- Soil protection: Fabric helps prevent erosion and compaction, especially in sloped areas.
- Mulch retention: It keeps mulch in place, reducing the frequency with which you need to refresh your beds.
But landscape fabric isn’t a “set it and forget it” solution. It can degrade over time, become clogged with soil and organic matter, and even become a haven for weeds if not maintained properly.
How to Maintain Landscape Fabric Over Time

1. Inspect Annually
At least once a year (ideally in early spring), take time to inspect the fabric in your garden beds or landscaped areas.
- Look for signs of wear, such as tears, holes, or areas where the fabric has been pulled up.
- Check for weed growth — especially persistent ones poking through seams or tears.
- Lift mulch carefully to check the condition of the fabric underneath.
2. Patch Small Holes and Tears
If you notice minor damage, you don’t always have to replace the entire fabric. Here’s what to do:
- Use landscape fabric tape or place a patch of new fabric over the damaged area.
- Secure the patch with landscape staples to prevent shifting.
- Cover with mulch again to restore the appearance and function.
3. Control Mulch Build-up
Organic mulch like bark or wood chips breaks down over time and can clog the fabric or create a compost-like layer on top that encourages weed growth.
- Rake and fluff mulch annually to break up compacted layers.
- Remove and replace old mulch every few years to prevent excessive buildup.
- Keep mulch depth around 2-3 inches — enough to block light but not so much that it suffocates the soil or fabric.
4. Re-secure Loose Edges
Over time, edges of the fabric may lift due to wind, water, or foot traffic.
- Re-pin edges and seams with landscape staples spaced every 12-18 inches.
- Overlap fabric edges by at least 6 inches if re-laying or repairing.
- Tuck the edges under mulch or soil to prevent fraying.
5. Prevent Root Intrusion
Plants with aggressive or spreading roots (like mint, bamboo, or invasive grasses) can pierce or grow under the fabric.
- Keep such plants in containers or raised beds instead of planting them directly in fabric-covered areas.
- Monitor root growth near seams or edges.
6. Clean Clogged Fabric
If water isn’t draining properly through the fabric anymore, it may be clogged with soil or organic debris.
- Lift and shake the fabric (if manageable) to dislodge debris.
- Rinse with a garden hose if needed.
- If cleaning doesn’t restore drainage, it may be time for replacement.
When to Replace Landscape Fabric

Even with great care, landscape fabric won’t last forever. Most professional-grade fabrics last 5 to 10 years, depending on conditions and quality.
Here are signs it’s time for a full replacement:
1. Widespread Tears or Deterioration
If the fabric is brittle, crumbling, or full of holes, it’s no longer functioning effectively. This is common with cheaper, non-woven fabrics after several seasons.
2. Persistent Weed Growth
If you’re constantly battling weeds growing through or on top of the fabric, it’s likely that the fabric has become compromised — by tears, soil buildup, or poor drainage.
3. Poor Drainage or Water Pooling
If water is pooling on top of your fabric, it might be clogged or compacted. Over time, soil, mulch, and organic debris can form an impermeable mat.
4. Severe Mulch or Soil Contamination
If the area has been overtaken by decomposed mulch and roots, it may be easier to start fresh than attempt to salvage the fabric underneath.
Tips for a Successful Replacement
When it’s time to start over, follow these best practices:
- Choose a high-quality, UV-stabilized fabric.
- Prepare the ground properly: remove all weeds, level the soil, and add a pre-emergent herbicide if desired.
- Overlap seams generously and secure with plenty of staples.
- Cover the fabric with mulch to protect it from sun exposure and degradation.
A Brand New Start with ECOgardener Landscape Fabric

Maintaining landscape fabric isn’t complicated, but it does require attention. With yearly inspections, occasional patching, and careful mulch management, you can extend its life and keep your garden looking its best. But when wear and tear or poor performance start to outweigh the benefits, don’t hesitate to replace it. A fresh start with quality material can make all the difference in restoring the weed-free, polished look you want for your landscape.
By knowing what to look for — and acting before small issues become big problems — your landscape fabric can continue to serve you for years to come.
