Ultimately, for a healthy urban area and garden, as well as a productive farm, managing unwanted plants is essential. Unwanted plants are competitive by nature and grow by continually fighting desired plants for soil nutrients and water. More importantly, they compete for the essential element for plant growth, which is sunlight. The biggest problem with unmanaged unwanted plants is that they will smother desired plants. Additionally, they will provide a habitat for pests, especially for the aggressive unwanted plants. Using herbicides for unwanted plant control will have a negative impact on the soil and water. Although pesticides have less impact on the environment, both have negative impacts on human health and the environment. Because of these effects, home gardeners prefer the use of geotextile garden fabrics. Garden Fabric weed barrier allow unwanted plants to block out soil, while letting through sunlight to the desired plants. The fabric also needs to allow air and water to go through it. For the fabric to hold moisture for the soil, desired plants need to be healthy.

The Art of Engineering and Composing Synthetic Geotextiles

The refinement of polymers, processes, and raw materials results in better products. High-density polypropylene and polyester polymers can be engineered to be woven or non-woven (random) in structure. Chemically stabilized UV additives can be further incorporated into the polymer structure to facilitate long-term end use UV exposure. High-Density polymer membranes provide better tear and tensile strength as compared to traditional plastics, organics, and biodegradable mulches. Since polymer membranes are designed to be stiff and inflexible to retain their designed conforms, they are best suited in structures that are adjacent to soil and concrete. Home Depot carries several of these products to the general public to control weeds. The public has a choice of various roll weights and incorporated UV stabilizers to protect membranes for end use in lightweight flower beds and heavier hardscapes.

Geotextile Ground Covers

Geotextile ground covers provide two major functions. First, they allow liquids and gases to move freely between the surface atmosphere and the subsurface soil profile. Second, they avoid stagnation of the soil ecosystem. Plastic sheets are incompatible with plants because they block the natural drainage of liquids to the soil profile. Additionally, they block the access of soil oxygen to the roots. As a result, the environment becomes hostile to plant growth. An engineered porous ground cover allows liquids and gases to move freely between the surface atmosphere and the subsurface soil profile. This cover is referred to as a breathable ground cover. The use of a breathable ground cover improves the health of plants and protects the soil surface from erosion. In addition, it maintains the optimal temperature of the roots.

Commercial Horticulture and Agricultural Production

Exclusion of unwanted vegetation in commercial fruit orchards and nurseries is good for crop health and the economy. Large-scale growers use heavy-duty woven geotextile fabrics as a barrier to control weeds. These fabrics are placed in the rows prior to planting and under staging tables in greenhouses. Hand weeding is not necessary with the use of these barriers. These fabrics serve functions of weed control and microclimate control. Weed barrier fabrics help control the microclimate by reducing evaporation from the soil and thus conserving soil moisture. Soil moisture is important for plant growth; therefore, conserving soil moisture is beneficial. Water conservation translates to monetary savings. Weed barrier fabrics help maintain a more constant soil moisture, ensuring the plants are properly hydrated during the growing season. Geotextile fabrics provide a clean surface and a smooth edge preventing contact between the soil and the produce. This eliminates the problem of produce coming in contact with wet soil and developing ground rot.

Civil Engineering and Infrastructure Landscape Utility

Integration of geotextiles into civil and municipal engineering projects is following the same trend as their integration in gardening projects. Geotextiles are known to control the movement of silt and fertilizer, stabilize composite paths and driveways, and control erosion. Woven geotextiles are used in creating and stabilizing soil foundations of composite paths and to control movement of pollen and weeds. Significant costs savings to municipalities and property owners are achieved due to the reduced need to maintain grounds. In general, in order to maintain a healthy garden and urban area as well as an efficient farm, management of unwanted plants is of great importance. As stated previously, unwanted plants are competitive by nature. They continually compete with your desired plants for nutrients, water and especially for light. The major problem of having unwanted plants in your garden is that they will eventually smother your desired plants and provide a place for pest to stay. This is even more evident with the most aggressive of unwanted plants.

Simplifications and Field Adjustability

There are several simplifications and field adjustments to be made, based on the site conditions. Once the area is clear of the large debris, rocks and large vegetation, a reasonably smooth and flat area is created for installation of the geotextile membrane. The edges of the geotextile fabric roll are easily shaped using utility scissors and modified to non-linear edges to accommodate tree guards and troughs. The fabric is fray resistant, and a two-inch seam allows for a good seal to prevent the passage of weed germination. For long-term edge protection, the fabric may be secured with heavy-duty steel landscape staples and secured along the perimeter. For the long term protection of the edge of the fabric, an organic mulch, bark or gravel may be placed on the geotextile fabric.

Sustainability and Chemical-Free Conservation

There are many ways to manage weeds that protect the world’s environment and promote sustainability. An example is the use of physical barriers to create a physical block to the sunlight needed for weed germination and therefore, eliminates the need for herbicides. The use of such physical barriers by homeowners protects earthworms and other soil organisms from herbicides. Further, because polypropylene is a fully recyclable membrane, the physical barriers serve property owners in protecting their property from weeds for a long time, in a way that is economical, sustainable and protective to the environment. Physical barriers, therefore, reduce the need for single-use agricultural films to protect crops from weeds.

Conclusion

The importance of sustainability has raised a great deal of international interest to conserve water as well as promote the practice of organic farming. This, coupled with the fast pace in the integration of new technology and the demand for more aesthetically pleasing surroundings, has led to the increased utilization of high performance Weed fabric barrier in the horticultural, agricultural and civil landscaping markets. Because of the increase in demand, the conservation of the environment and other protective measures, synthetic weed barriers will continue to replace the use of chemical control of weeds. This is because synthetic barriers will be used to safeguard ecosystems, and protect water and other organisms. Regarding home gardening, the risk of using pesticides and herbicides on plants has been well documented and the effects can be severe and long lasting. Most concerned home gardeners use geotextile fabrics in their gardening practice to control the growth of unwanted plants, instead of pesticides and herbicides. Geotextile fabrics are essentially light and air permeable. They allow water to permeate through the fabric. 

Frequently Asked Questions (FAQs)

Will a garden weed barrier fabric allow liquid fertilizer and water to reach plant roots?

Yes, a good quality landscape fabric will have a pore-like structure which will allow for water from rain, liquid nutrient and oxygen to be able to enter the soil to help with the growth of roots.

What can I do to keep weeds out of the mulch layer applied on top of my weed barrier?

Over time dust and organic matter collect on top of the mulch which creates a small amount of soil for seeds to grow in. Pull any stray seedlings out of the ground as soon as possible, so that they don't have enough time to dig through the fabric beneath.
