If you have been wondering whether using landscaping fabric in your yard will gradually kill the grass, you are not alone. Many homeowners are faced with this concern as they weigh the benefits of using landscaping fabric against the potential harm to their lawn. In this article, we will explore the effects of landscaping fabric on grass over time and provide valuable insights to help you make an informed decision for your landscaping needs.

What is Landscaping Fabric?


Landscaping fabric, also known as weed fabric or landscape fabric, is a durable material designed to be placed on the ground to suppress the growth of weeds. It is typically made of woven or non-woven polypropylene and is permeable to water and air while blocking sunlight.


The main purpose of landscaping fabric is to act as a barrier between the soil and the weeds, preventing weed seeds from germinating and growing. It helps to keep the landscape tidy and reduces the need for manual weeding, saving you time and effort in maintaining your garden or yard.


There are various types of landscaping fabric available on the market, each with its own unique characteristics and applications. Some common types include woven fabric, which is more durable and suitable for areas with heavy foot traffic, and non-woven fabric, which is easier to cut and install. Additionally, there are specialized fabrics designed for specific purposes, such as erosion control or moisture retention.

The Effect of Landscaping Fabric on Grass

Preventing Grass Growth

While landscaping fabric effectively inhibits the growth of weeds, it can also impact the growth of grass if not properly installed or maintained. The fabric creates a physical barrier that hinders the growth of grass seeds, preventing them from establishing and thriving in the soil.

Root Disturbance

Another potential effect of landscaping fabric on grass is root disturbance. As grass roots grow and spread, they can encounter the fabric, causing them to divert their growth or become entangled. This can lead to poor root development, resulting in weaker grass that is more susceptible to damage from external stressors.

Nutrient and Water Deprivation

Landscaping fabric may also affect the availability of essential nutrients and water for grass. While the fabric allows some water and nutrients to pass through, it can reduce the amount that reaches the grass roots. If not supplemented adequately through proper watering and fertilization, the grass may suffer from nutrient deficiencies and dehydration, which can contribute to its deterioration over time.

The Process of Grass Deterioration

Gradual Weakening

When exposed to the limitations imposed by landscaping fabric, grass gradually weakens over time. Its growth may become stunted, resulting in discolored patches and thinning areas. As the fabric restricts the grass’s access to sunlight, air, and nutrients, its ability to thrive and maintain a healthy appearance diminishes.

Thinning and Yellowing

As the grass’s health continues to deteriorate, it may begin to thin out, leaving bare or patchy areas. The lack of proper nourishment and restricted root growth can lead to the yellowing of the grass blades, indicating a nutrient deficiency. These visual changes are often early signs of the negative impact of landscaping fabric on grass health.

Death and Decay

If the issues caused by landscaping fabric are left unresolved, the grass may ultimately die off in the affected areas. The lack of sunlight, nutrients, and water can lead to the gradual decay of the grass, leaving behind bare soil or areas covered with dead turf. This not only compromises the aesthetic appeal of the landscape but also necessitates costly and time-consuming repair or re-sodding efforts to revive the area.

Factors Influencing Landscaping Fabric’s Impact on Grass

Fabric Thickness

The thickness of the landscaping fabric plays a crucial role in its impact on grass health. Thicker fabrics provide stronger weed suppression but can also hinder grass growth more significantly. It is essential to choose a fabric thickness that strikes a balance between weed control and grass health, considering the specific needs of your landscape.

Installation Techniques

Proper installation techniques can minimize the negative impact of landscaping fabric on grass. Ensuring the fabric is properly secured to the ground and overlapping the edges sufficiently can prevent weed penetration while allowing room for grass roots to develop. Professional guidance or research can help you understand the best practices for installing landscaping fabric in your specific landscape.

Duration of Use

The duration for which the landscaping fabric is left in place can also influence its impact on grass. Overextended periods of using the fabric without regular assessment and maintenance can lead to more severe negative effects on grass health. Regular inspection, replacement, and modifications to the fabric’s placement may help mitigate the potential damage to grass while still benefiting from weed control.

Alternatives to Landscaping Fabric


Mulching is a popular alternative to landscaping fabric for suppressing weeds and protecting grass. Organic mulches, such as wood chips or straw, provide an additional aesthetic element while also improving soil moisture retention and nutrient availability. Mulching allows for microbial activity and earthworm movement while reducing weed growth and supporting the health of the grass.

Ground Covers

Using ground covers, such as low-growing plants or ornamental grasses, can offer both weed control and an attractive ground layer. Ground covers act as living mulch, competing with weeds for resources and preventing their establishment. Some examples of effective ground covers include creeping thyme, sedum, or even moss, depending on the specific requirements and climate of the landscape.

Weed Control Methods

Implementing targeted weed control methods, such as manual removal, herbicides, or spot treatments, can be an effective way to combat weed growth without negatively impacting the grass. Regularly inspecting and addressing weeds before they spread can prevent any larger-scale invasion that may necessitate the use of landscaping fabric.

Proper Maintenance Practices

Regular Inspection and Replacement

Regularly inspecting the condition of the landscaping fabric is crucial to identify any signs of grass deterioration or damage. Additionally, replace worn-out or damaged fabric promptly to avoid further harm to the grass. Adjusting the fabric’s placement periodically may also be necessary to accommodate the changing needs of the grass and prevent long-term negative effects.

Watering and Fertilization

Adequate watering and fertilization are essential components of maintaining grass health, especially when landscaping fabric is used. Ensuring that the grass receives sufficient water and nutrients, either through rainfall or irrigation, can help counteract the potential deprivation caused by the fabric. Consult with a lawn care professional or refer to specific guidelines for proper watering and fertilization practices.

Aeration and Seeding

Regularly aerating the soil and overseeding can help counteract the negative impact of landscaping fabric on grass. Aeration promotes root growth and allows for better nutrient and water absorption, while overseeding replenishes the grass population and helps fill in any bare areas. These practices support grass health and recovery from any damage caused by the fabric.
