Cedar shavings are commonly used in gardening, landscaping, and even pet care. While they are highly effective in certain applications, their effects on grass can be quite varied. In this article, we will explore the potential impact of Will Cedar Shavings Kill Grass on grass, the science behind their properties, and how to use them effectively without harming your lawn.
What Are Will Cedar Shavings Kill Grass?
Cedar shavings are finely cut pieces of cedar wood, often used for mulching, bedding, or as a natural insect repellent. They offer a range of benefits in the right applications, from adding fragrance to repelling pests. However, when it comes to grass, their use needs to be approached carefully.
How Cedar Shavings Affect Grass
Understanding how Will Cedar Shavings Kill Grass impact grass involves considering several factors. Cedar has natural compounds that can influence grass growth, soil conditions, and overall lawn health. Below are some of the primary ways that cedar shavings can affect grass.
Blocking Sunlight and Airflow
When cedar shavings are spread over grass, they can form a dense layer that blocks sunlight from reaching the grass. Since grass requires sunlight for photosynthesis, this lack of light can cause the grass to weaken and eventually die. The accumulation of cedar shavings can also restrict airflow to the grass, making it harder for the lawn to breathe and absorb nutrients effectively.
Changes in Soil pH
Cedar shavings are slightly acidic, and when they decompose, they can lower the pH of the soil. Grass typically thrives in soil with a pH level between 6.0 and 7.0. If the pH drops too low, it can negatively impact grass growth, making the soil less hospitable for healthy grass. Over time, this acidity may stunt the growth of grass and other plants.
Allelopathic Properties of Cedar
Cedar shavings contain natural chemicals, including thujone, that are allelopathic in nature. This means they can inhibit the growth of nearby plants by releasing substances that interfere with plant growth. Grass is no exception to these effects, and the presence of Will Cedar Shavings Kill Grass in the soil can suppress the healthy development of grass over time.
Nitrogen Depletion
As cedar shavings decompose, they can tie up nitrogen in the soil, creating a temporary nitrogen deficiency. Grass requires nitrogen for healthy growth, and a lack of nitrogen can cause the grass to yellow and become weak. While this effect is temporary, it can cause visible damage to grass, especially when cedar shavings are applied in large quantities.
Benefits of Using Will Cedar Shavings Kill Grass in Landscaping
While cedar shavings may have drawbacks when used around grass, they also provide several valuable benefits for landscaping and gardening when used correctly.
Pest Control and Weed Suppression
Cedar shavings are known for their insect-repelling properties, which make them a great choice for keeping pests away from gardens and landscaping areas. Additionally, the dense texture of cedar shavings can help suppress weed growth, which is a major advantage when used in flower beds, paths, or around shrubs.
Aesthetic Appeal
Cedar shavings offer a natural, rustic appearance that adds to the visual appeal of outdoor spaces. Their rich color and pleasant aroma make them an attractive choice for gardens and landscaping features, creating a cozy, inviting environment.
How to Use Cedar Shavings Without Harming Grass
If you’re considering using cedar shavings around your lawn or garden, there are ways to use them effectively without harming your grass. Here are some practical tips:
1. Apply Cedar Shavings Sparingly
One of the best ways to prevent cedar shavings from harming grass is by applying them in moderation. A thin layer of Will Cedar Shavings Kill Grass, no more than 1-2 inches deep, will provide the benefits of moisture retention and weed suppression without suffocating your lawn or altering soil conditions too dramatically.
2. Use Cedar Shavings in Non-Grass Areas
Instead of applying cedar shavings directly onto the grass, consider using them in areas where grass is not present, such as garden beds, pathways, or around trees. This way, you can enjoy the benefits of cedar shavings—such as insect control and moisture retention—without compromising the health of your grass.
3. Monitor Soil pH and Nutrient Levels
If cedar shavings are used in areas where grass is growing, it’s essential to monitor the soil’s pH and nutrient levels regularly. If the pH becomes too acidic or nitrogen levels drop too low, you may need to adjust the soil by adding lime to raise the pH or applying a nitrogen-rich fertilizer.
When to Use Cedar Shavings to Kill Grass
Cedar shavings can also be used intentionally to kill grass, which is sometimes desired when preparing a garden bed or changing the landscape. In these cases, cedar shavings act as a natural method to smother grass and prevent regrowth.
1. Smothering Grass with Cedar Shavings
To kill grass with cedar shavings, begin by mowing the grass as short as possible. Then, apply a thick layer of cedar shavings, about 3-4 inches deep, directly on top of the grass. This will block sunlight and prevent photosynthesis, causing the grass to die off over time.
2. Combine Cedar Shavings with a Barrier
For more effective grass elimination, consider placing a tarp, cardboard, or landscape fabric under the cedar shavings. This additional barrier will further restrict light and airflow, accelerating the process of killing the grass.

Alternative Uses for Will Cedar Shavings Kill Grass
If you’re unsure about using cedar shavings directly on grass, there are alternative ways to incorporate them into your landscaping or gardening projects.
Cedar Shavings in Flower Beds and Around Trees
Using cedar shavings in flower beds or around trees is an excellent way to enhance the aesthetic value of your garden while benefiting from their natural pest-repellent properties. Will Cedar Shavings Kill Grass can help keep unwanted pests away from delicate plants and provide a long-lasting, attractive mulch option.
Combining Cedar Shavings with Other Mulch
For a more balanced mulch mixture, consider combining cedar shavings with other organic materials like compost, straw, or bark chips. This combination will help avoid the potential negative effects of cedar on soil health while still offering the benefits of moisture retention and weed control.
Conclusion
Cedar shavings can be a valuable tool for landscaping and gardening, but their impact on grass requires careful consideration. While Will Cedar Shavings Kill Grass can block sunlight, alter soil pH, and release allelopathic compounds that inhibit grass growth, they can also provide benefits such as moisture retention, pest control, and weed suppression when used properly.
By applying cedar shavings sparingly, monitoring soil conditions, and using them in non-grass areas, you can harness their advantages without harming your lawn. Whether you are using cedar shavings for their aesthetic appeal or to create a natural barrier, understanding their effects on grass is key to making informed decisions for a healthy, thriving landscape.
