How Landscape and Fabric Barriers Work

Landscaping fabrics are useful in maintaining vibrant, beautiful flower beds and landscaping. They stabilize soil, keep moisture, and help minimize weed growth.

These barriers are usually made of fabric or plastic materials. They are available in large rolls that can cover several feet of ground.

The type of material used for the weed barrier will determine its weight, durability and permeability.

Depending on whether it is plastic, fabric, or a blend of both, the barrier can also act as a separation layer, a protective water barrier under porches and decks, or as a reinforcing layer under a driveway or sidewalk.

Plastic barriers are not well-suited for landscaping. Although barriers can prevent weeds, they can also suffocate the soil.

When living organisms are denied proper air flow, the soil suffers as well. Plastic sheets prevent both air and moisture from maintaining a delicate balance for preserving plant life.

Agfarbric Weed Barrier for Landscaping

For flower beds landscaping, consider using a fabric weed barrier to help with moisture preservation and ventilation. Fabric barriers will still help reduce weed growth while still allowing the soil to breathe.

Fabric will let moisture in, while also keeping it in. This nourishes the soil and plant roots while aiding in water conservation.

Weed Barrier Landscape Fabric Advantages

Compared to the plants, soil, fertilizer, and other materials that go into landscaping, weed barriers are an economical addition with overwhelming benefits, such as proper ventilation and moisture retention.

What is the Best Weed Barrier Material – Plastic VS Fabric VS Natural

Weed Barrier types - professional and home owner

Plastic Weed Barriers

Plastic weed barriers have been around for a long time. Black plastic is the most effective at weed prevention since it smothers everything under it. Its disadvantage is that it can also suffocate plant roots and starve the soil. It may block moisture and water going through while potentially leaving puddles of water.

Plastic weed barriers can limit photosynthesis and gas exchange. They are also less environmentally friendly option.

Plastic will also break down when exposed to sunlight over time, so may not be a good option for permanent landscaping projects.

Plastic barriers will work better in annual beds that need to be re-planted every season.

Fabric Weed Barriers

Fabric weed barriers are highly regarded in the gardening world because of their longevity.

When properly installed, the best landscape fabric and barriers can last many years.

Fabric also allows better ventilation, allowing plants and soil to breathe.

Adding organic or stone mulch will enhance the fabric’s durability and effectiveness, as well.

Some weeds will still poke through , but not as many as there would be if a barrier was not present. And it is much less likely to damage soil or other plant growth.

Natural Weed Barriers

One alternative to plastic and fabric weed barriers is the natural materials gardeners have been using for centuries.

Mulch, moss, straw, and other items found in nature help cut down on weed growth.

To calculate the amount of mulch you may need, use our mulch and soil calculator.

Since they are completely biodegradable, once their compounds break down into the soil, the natural materials will also act as compost and put nutrients back into the soil.

Natural weed barriers do have to be replaced or topped up at least once a year. Although they can be used alone, when used on top of a fabric weed barrier it enhances weed prevention.

Choosing a Weed Barrier

When selecting the best weed barrier to use, consider what its purpose will be.

For barriers under driveways, patios or walkways, the longevity and moisture control that plastic offers may be best.

Plastic may also be considered along with natural materials for annual flower beds and landscaping projects that do not need to last several years.

Also consider the potentially detrimental effects some plastic barriers can have on the soil.

For larger landscapes that require more permanence, consider a fabric barrier coupled with quality mulch to enhance its longevity and effectiveness at air ventilation and moisture absorption.
