Landscape Fabric Pros and Cons

Landscape fabric is a woven or nonwoven material placed over soil to reduce weed growth while allowing some movement of air and water. It can be useful in certain permanent landscape situations, but it is not a universal weed-control solution. Over time, mulch and organic debris can accumulate on top, weeds can root above the fabric, and the material can complicate planting, soil improvement, and removal.

Understand What Landscape Fabric Is

Landscape fabric is designed to create a physical barrier between soil and the surface layer.

Know What It Can Do Well

It can reduce germination of some weeds rising from the soil below.

Know What It Cannot Prevent

Windblown weed seed can germinate in mulch or soil that accumulates on top.

Use It Selectively

Fabric is usually more suitable for long-term ornamental areas than frequently replanted vegetable beds.

Consider Permanent Shrub Beds

Areas with widely spaced woody plants may be easier to maintain with a barrier than annual planting areas.

Consider Pathways

Fabric under gravel paths can help separate soil from stone and slow weed emergence.

Do Not Expect Zero Weeds

No landscape fabric eliminates all weed growth indefinitely.

Prepare the Soil Before Installation

Remove perennial weeds and major roots before covering the area.

Do Not Cover Aggressive Perennial Weeds Blindly

Some weeds can grow through openings, seams, or edges.

Overlap Seams

Gaps between fabric sections can become easy paths for weeds.

Secure the Edges

Loose fabric can shift, expose soil, or become a trip hazard.

Cut Planting Holes Carefully

Keep openings only as large as needed for the plant.

Do Not Wrap Fabric Tightly Around Stems

Leave room for trunks and stems to expand.

Keep Fabric Away From Tree Trunks

Do not create a tight collar that traps moisture against bark.

Cover Fabric With Mulch or Stone

Exposed fabric can degrade, shift, or become visually unattractive.

Use Enough Cover Material

Very thin mulch layers may expose the fabric quickly.

Do Not Pile Mulch Against Crowns

Keep organic material away from stems and trunks.

Expect Organic Mulch to Break Down

As mulch decomposes, it can form a layer of soil-like material on top of the fabric.

Expect Weeds to Root Above the Fabric

Once organic matter accumulates, weed seed can germinate without contacting the soil below.

Pull Surface Weeds Early

Small weeds are easier to remove before roots become tangled in the fabric.

Know That Roots Can Grow Into Fabric

Plant roots and weed roots can sometimes penetrate or entangle woven materials.

Removal Can Become Difficult

Older fabric may be buried under mulch, roots, and decomposed material.

Consider Future Bed Changes

Fabric can make frequent replanting and soil amendment more inconvenient.

Avoid Fabric in Intensive Vegetable Beds

Annual crops are often planted, removed, amended, and rotated too frequently for permanent fabric to be convenient.

Consider Organic Mulch Instead

Wood chips, leaves, straw, or other materials can suppress weeds while contributing organic matter over time.

Know That Organic Mulch Also Has Limitations

It decomposes and needs replenishment.

Consider Cardboard for Temporary Suppression

Plain cardboard can be useful under mulch in some temporary weed-smothering situations.

Avoid Contaminated or Coated Materials

Do not use questionable waste products simply because they can cover soil.

Consider Gravel Areas

Fabric may help keep gravel from mixing rapidly with soil below.

Expect Sediment to Accumulate in Gravel

Dust, leaves, and organic debris eventually create conditions for weeds above the fabric.

Use Fabric on Slopes Carefully

Water moving over a covered surface can create erosion problems if runoff is concentrated.

Do Not Block Natural Drainage

Installation should not redirect water toward buildings or neighboring property.

Check Water Infiltration

Some fabrics pass water more effectively than others.

Do Not Assume Fabric Solves Drainage Problems

Poor soil drainage remains a separate issue.

Consider Soil Biology

A permanent barrier changes how organic material reaches and mixes with the soil surface.

Consider Earthworm Access

Physical barriers can change how surface residues interact with soil organisms.

Avoid Plastic Sheeting for Ordinary Landscape Beds

Impermeable plastic can interfere with air and water movement much more strongly than landscape fabric.

Know When Plastic Is Used for Other Purposes

Specialized horticultural uses such as solarization or plastic mulch are different from permanent landscape weed barriers.

Use Fabric Around Drip Irrigation Carefully

Place irrigation so water reaches the root zone effectively.

Inspect Irrigation Lines

Fabric and mulch can hide leaks or clogged emitters.

Do Not Cover Utility Access

Keep irrigation valves, cleanouts, and other service points accessible.

Check Fabric Annually

Look for exposed edges, tears, buried crowns, or weed growth.

Repair Small Problems Early

Loose sections and open seams become harder to correct later.

Remove Fabric When It No Longer Serves a Purpose

Do not keep deteriorated material buried simply because it was installed years ago.

Dispose of Old Synthetic Fabric Properly

Most landscape fabrics should not be mixed into compost or soil.

Use the Least Permanent Method That Meets the Goal

Temporary mulch may be more practical when a bed is likely to change.

Practical Takeaway

Landscape fabric can reduce weeds and separate gravel from soil in stable long-term areas, but it does not eliminate future weed growth and can complicate soil improvement, replanting, and removal. Use it selectively, install it carefully, cover it properly, and consider organic mulch or other less permanent methods where beds change frequently.
