Should You Use Plastic Sheeting Under Landscape Rocks?

When considering the placement of landscape rocks in your garden or outdoor space, it is essential to choose materials that will enhance both aesthetics and functionality. One common question is whether to use plastic sheeting under landscape rocks. However, many experts recommend against it. Let's explore why and what alternative materials are more suitable.

Why Not Plastic Sheeting?

No. It degrades too quickly. Plastic sheeting, while initially effective, is not a long-term solution for landscape projects. Over time, it degrades due to exposure to sunlight, moisture, and other environmental factors. This degradation can compromise the overall integrity of your landscape design, leading to uneven surfaces and a less durable finish.

Using weed mesh or landscaping fabric is a better option. Weed mesh and landscaping fabric are designed to provide a barrier against unwanted weeds and roots while still allowing water and air to pass through. They offer a more sustainable and effective solution for maintaining a healthy ecosystem beneath your landscape rocks.

Advantages of Weed Mesh and Landscaping Fabric

Almost impenetrable plastic sheeting can hinder water and air transmission. This is counterproductive, as soil needs both air and water to function properly. Permeable fabrics ensure that these elements can move freely, which is crucial for healthy plant growth and root development.

For those seeking an affordable and accessible solution, a filter fabric can be just as effective. Filter fabrics are another type of permeable fabric that allows water and air to pass through while preventing weed growth. They are commonly used in landscaping and construction projects to provide a durable weed barrier.

Risks and Considerations

Using plastic sheeting under landscape rocks can lead to several unwanted outcomes:

Water pooling and mosquito breeding. If you choose to use plastic sheeting, water is likely to collect and pool in certain areas. This not only creates breeding grounds for mosquitoes but also leads to unhealthy and molded soil conditions. Uneven water and air distribution. The impermeable nature of plastic sheeting can result in poor water circulation and air movement, which can negatively impact plant health and overall landscape aesthetics. Potential drainage and washing problems. In areas with steeper grades, using plastic sheeting can lead to drainage issues, causing the soil to wash away and resulting in an uneven surface.

Contrarily, a landscape fabric designed for landscape use is a much better choice. It allows water and air to pass through while effectively preventing weed growth. This material is woven and not fused, ensuring optimal functionality and durability.

When looking for landscape fabric specifically, garden and landscaping centers are your go-to locations. Make sure to choose a woven fabric rather than a fused fiber mat. For heavy-duty options, you may want to look for materials used in road construction, as these are typically the heaviest and best. These often come in large rolls from culvert or road construction supply companies.

Conclusion

While plastic sheeting might seem like a quick and easy solution, its short-term benefits come at the cost of long-term maintenance and functionality. By choosing weed mesh or landscape fabric, you ensure a more sustainable, efficient, and healthy landscape design. Investing in the right materials from the start can save you time and money in the long run, providing a beautiful and functional outdoor space for years to come.
