Landscape fabric is a popular method for controlling weeds and improving soil moisture in gardens and landscaping. However, one question that often arises is whether or not it is necessary to remove grass before laying landscape fabric.
In short, you don’t need to remove grass. It is not a requirement to extract existing grass prior to laying landscape fabric. However, it is necessary to ensure that the grass is trimmed to the lowest possible height, and a trench measuring approximately 12 inches in depth should be created around the perimeter of the grass. In this article, we’ll explore the pros and cons of removing grass before laying landscape fabric, as well as alternative methods for preparing the area.

Landscape Fabric and Its Benefits
Landscape fabric, also known as weed barrier cloth, is a material that is designed to prevent weed growth and aid in soil erosion control. It is a permeable textile material that is placed over the soil before planting to inhibit the growth of weeds and promote healthy plant growth.
The fabric is typically made from polypropylene or polyester materials and comes in various thicknesses and grades. It can be used in a variety of landscaping projects, including garden beds, walkways, and retaining walls.
The use of landscape fabric offers several benefits. Firstly, it helps to prevent weeds from growing, which can reduce the amount of time and effort required for maintenance. Additionally, it can help to conserve soil moisture, prevent soil erosion, and regulate soil temperature. Landscape fabric is also an effective way to reduce the need for chemical herbicides, which can be harmful to the environment.
When used properly, landscape fabric can improve the overall health and appearance of your landscaping. It can provide a barrier between the soil and any potential weeds or invasive plant species, allowing your desired plants to grow and flourish.
Why Remove Grass before Laying Landscape Fabric?
When it comes to laying landscape fabric, some people recommend removing any grass or vegetation that may be present in the area where the fabric will be installed. This is because there are concerns that the grass may grow through the fabric or cause issues with drainage and water retention.
If grass is left in place, it can continue to grow and potentially cause problems with the landscape fabric. The roots of the grass may grow through the fabric, making it less effective at preventing weed growth. Additionally, the grass may create an uneven surface, which can cause water to pool or drain improperly.
Another potential issue with leaving grass in place is that it can create a hospitable environment for pests such as insects and rodents. These pests can burrow through the fabric and cause damage to the landscaping, including your desired plants.
By removing the grass before laying landscape fabric, you can ensure that the fabric has a smooth and even surface to lay upon. This can improve the overall effectiveness of the fabric in preventing weed growth and promoting healthy plant growth. Additionally, it can help to prevent issues with water drainage and retention.
It is important to note that while removing grass may be beneficial in some cases, it may not always be necessary. If the grass is already dead or there is a thick layer of mulch or other materials on top of the soil, it may not be necessary to remove the grass before laying the fabric.
Ultimately, the decision to remove grass before laying landscape fabric will depend on the specific landscaping project and its unique needs. It is always a good idea to consult with a landscaping professional to determine the best course of action for your project.
Alternatives to Prepare Your Garden Bed Before Laying Landscape Fabric
Landscape fabric is a popular solution for weed control and soil stabilization in garden beds, but many gardeners are unsure about whether they need to remove grass before laying the fabric. While some people recommend removing the grass entirely, there are alternative methods that can save time and effort while still achieving great results.
One such method is using herbicides to kill the grass before laying the fabric. This can be an effective approach if you want to avoid manually removing the grass, but it does require careful application to ensure that the herbicide doesn’t affect other plants or wildlife in the area. Be sure to follow the instructions carefully and use a product that is safe for your garden.
Another alternative is to use a sod cutter or manually remove the grass before laying the landscape fabric. This can be a more time-consuming approach, but it ensures that the grass won’t grow through the fabric or cause issues with drainage. It’s important to remove as much of the root system as possible to prevent the grass from regrowing.
Impact of Grass Removal on Soil Health When Using Landscape Fabric
Removing grass from the area before laying landscape fabric can have both positive and negative impacts on soil health.
On one hand, it can prevent the buildup of thatch and reduce the competition between grass and other plants for nutrients and water. This can benefit the growth of other plants, including the ones planted on top of the landscape fabric.
On the other hand, removing grass can also cause the loss of organic matter, which is essential for healthy soil. Grass roots help to improve soil structure by providing channels for air and water to move through. When grass is removed, these channels disappear, and soil structure can become compacted, leading to poor drainage and aeration.
To mitigate any negative impacts of grass removal on soil health, it is important to add organic matter back into the soil. This can be done by adding compost, well-rotted manure, or other organic materials to the soil before laying the landscape fabric. Additionally, using aeration tools such as a pitchfork or aerator can help improve soil structure and allow air and water to move through the soil more easily.
Another option is to use a method called sheet mulching, where layers of organic matter, such as cardboard or newspaper, are placed over the grass before laying landscape fabric. This method allows the grass to decompose naturally, adding organic matter back into the soil.
Tips for Removing Grass
Use a sod cutter
If you have a large area of grass to remove, consider using a sod cutter. This tool can help you remove the grass and roots quickly and efficiently.
Cut the grass short
Before you start digging, mow the grass as short as possible. This will make it easier to remove and reduce the risk of the grass growing back.
When removing the grass, be sure to dig down deep enough to remove the roots. If you leave any roots behind, the grass may grow back.
Strategies for Disposing of Grass
Once you’ve removed the grass, you’ll need to dispose of it. Here are some options.
If you have a compost bin, you can add the grass clippings to it. Grass clippings are high in nitrogen and can be a great addition to your compost.
If you don’t have a compost bin or if you have a large amount of grass to dispose of, you may need to take it to the landfill.
If you have a chipper or shredder, you can turn the grass clippings into mulch. This can be a great way to reuse the grass and add nutrients to your soil.
Learning from Other Gardeners’ Experiences
While some people recommend removing the grass to prevent it from growing through the fabric or causing issues with drainage and water retention, others argue that leaving the grass in place can help retain soil structure and organic matter. To help readers make an informed decision, it can be useful to examine real-world case studies of gardeners who have tried both methods.
Case Study 1: Removing Grass
Samantha is an experienced gardener who decided to install landscape fabric in her front yard to create a low-maintenance garden. Before laying the fabric, she decided to remove the grass using a sod cutter. While it was a lot of work, Samantha was pleased with the results. The landscape fabric was easy to lay and there were no issues with the grass growing through it.
However, Samantha noticed that the soil in her front yard was noticeably compacted and lacking in organic matter. She had to amend the soil with compost before planting, which added extra time and expense to the project.
Case Study 2: Leaving Grass
John is a new gardener who decided to install landscape fabric in his backyard to create a raised bed vegetable garden. He chose to leave the grass in place and simply mow it as short as possible before laying the fabric. John was pleased with how easy it was to lay the fabric and there were no issues with the grass growing through it.
He noticed that the soil in his backyard was loose and full of organic matter, likely due to the grass being left in place. John was able to plant his vegetables directly into the soil without any amendments.
Based on these case studies, it seems that both methods can be successful depending on the condition of the soil and the amount of work the gardener is willing to put in. Removing the grass may be necessary if the soil is compacted and lacking in organic matter, but it can be time-consuming and expensive to amend the soil afterward. Leaving the grass in place may be a good option if the soil is already loose and full of organic matter, but it may require more frequent weeding and maintenance. The decision to remove grass or leave it in place before laying landscape fabric should be based on the individual gardener’s needs and the condition of their soil.
Can you put landscape fabric over existing grass?
It is not recommended to put landscape fabric over existing grass as it may lead to issues with water and nutrient absorption, and the grass may eventually grow through the fabric. It is generally recommended to remove the grass before laying landscape fabric.
