Should You Use Landscape Fabric?

Landscape fabric was once promoted as a simple solution to one of gardening's most persistent problems: weeds. The idea sounds appealing. Lay down a barrier, cover it with mulch, and spend less time pulling weeds. For many gardeners, landscape fabric appears to work well at first.

However, after several years, many homeowners discover that landscape fabric often creates new problems while failing to eliminate the original one. As a result, an increasing number of gardeners are choosing alternatives such as cardboard, wood chips, compost, and other organic mulches.

What Is Landscape Fabric?

Landscape fabric is a woven or spun synthetic material typically placed on the soil surface and covered with mulch, gravel, or stone. Unlike solid plastic sheeting, landscape fabric is designed to allow water and air to pass through while helping suppress weed growth.

It is commonly used in landscape beds, around shrubs, beneath decorative stone, and along pathways.

Why Landscape Fabric Became Popular

The biggest selling point of landscape fabric is weed suppression. When installed over bare soil and covered with mulch, it can significantly reduce weed growth during the first few years. Many gardeners appreciate the cleaner appearance and reduced maintenance compared to newly mulched beds without fabric.

Landscape fabric can also help separate decorative stone from underlying soil and may provide erosion control on slopes.

These benefits explain why landscape fabric remains widely available and commonly recommended.

The Problem: Weeds Usually Come Back

One of the most common complaints about landscape fabric is that it rarely provides permanent weed control. Nature constantly deposits leaves, dust, pollen, mulch particles, and other organic debris onto the soil surface. Over time, this material accumulates above the fabric and begins to resemble soil.Eventually, weed seeds germinate in this new layer.

At that point, weeds are no longer growing through the fabric. They are growing on top of it. Many gardeners discover that they are once again pulling weeds, even though the landscape fabric remains in place underneath.

It Can Slow Soil Improvement

Healthy soil develops when organic matter is continually added and incorporated into the ground. Leaves fall. Mulch decomposes. Plant roots die and regrow. Earthworms and microorganisms break down organic material and mix it into the soil.

Landscape fabric interrupts part of this process.

Although water can usually move through the material, organic matter does not move as freely. Over time, mulch often breaks down on top of the fabric instead of becoming part of the soil below.

Gardeners who remove old landscape fabric are sometimes surprised to find that the soil underneath has improved far less than expected despite years of mulching.

It Can Make Gardening More Difficult

Landscape fabric is easy to install but often difficult to live with long term. Many gardeners eventually want to add new plants, divide perennials, move shrubs, or redesign a bed. Landscape fabric can turn these routine tasks into frustrating projects.

Roots frequently grow through the material, making it difficult to pull up. As the fabric ages, it may tear into smaller pieces that become tangled with roots and mixed into the soil.

What began as a time-saving measure can eventually become a cleanup project.

Most Landscape Fabric Is Not Biodegradable

Many gardeners assume landscape fabric will eventually decompose naturally. Most products do not.

The majority are made from synthetic materials such as polypropylene or polyester. While these materials may weaken over time, they often remain in the landscape for many years. Older fabric frequently becomes brittle and tears into fragments that can be difficult to remove completely.

Concerns About Microplastics

Because most landscape fabric is made from plastic-based materials, some gardeners are concerned about its contribution to microplastic pollution. As the fabric ages and deteriorates, small fibers and fragments may be released into the surrounding soil. Research on the long-term impacts is ongoing, but the concern has led some gardeners to seek biodegradable alternatives.

For those trying to reduce plastic use in the landscape, landscape fabric may be difficult to justify.

Are There Situations Where Landscape Fabric Makes Sense?

Landscape fabric is not entirely without value. Many professionals still use it successfully beneath gravel pathways, decorative stone, and certain hardscape installations where soil improvement is not a primary goal. In these situations, the fabric functions more as a separator than a weed-control system.

The drawbacks tend to become more significant in actively managed garden beds where plants, compost, and mulch are expected to improve the soil over time.

Better Alternatives for Most Garden Beds

Many gardeners now prefer methods that suppress weeds while also building soil health.

Common alternatives include:

  • Wood chips
  • Shredded bark mulch
  • Pine needles
  • Straw
  • Compost
  • Leaf mold
  • Cardboard sheet mulching

These materials help suppress weeds, conserve moisture, moderate soil temperatures, and gradually add organic matter to the soil as they decompose. Unlike landscape fabric, they do not create a long-term barrier that eventually needs to be removed.

Final Thoughts

Landscape fabric can provide short-term weed suppression, but many gardeners find that the benefits decline over time while the drawbacks become more apparent.

Weeds often return, soil improvement may be slowed, future planting becomes more difficult, and synthetic fabric can remain in the landscape long after it has stopped serving a useful purpose.

For gardeners focused on building healthy soil, many organic alternatives provide effective weed suppression while contributing to the long-term health of the garden. In most planting beds, the goal should not simply be to cover the soil but to improve it year after year.
