Build A Raised Garden With Silt Fencing Instead Of Wooden Boards

If you plan to build a large raised garden but don't want to use wooden boards that might rot or break down if they become wet, consider using silt fencing instead. Silt fencing material is often used in situations that require temporary protection against soil erosion. But the fencing may also be of good use to you because it allows excess water to drain through it without degrading your soil. Here's how silt fencing works and how you can use it for your garden instead of wooden boards.

How Can Degraded Soil Occur?

Heavy rainfalls, strong winds and other factors can all degrade soil in a process called erosion. Soil erosion removes the topsoil from your landscape. Topsoil typically contains a host of valuable minerals and other nutrients that make it healthy and suitable for good vegetable and flower growth. Without the right barrier around it, your new garden can lose its topsoil to water runoff.

Most raised gardens use wooden boards to keep them intact after planting. But the boards can deteriorate or rot over time if they're exposed to a lot of water, such as heavy seasonal rainfalls. Even if you use cedar for your raised garden bed, it can still experience some issues in the future if it stays wet. Silt fencing is an alternative to wooden boards because it doesn't rot from moisture.

How Do You Use Silt Fencing For Your Garden?

Silt fencing is made of a strong synthetic material or fabric that allows liquid to travel through it. Silt fencing material is porous, which means that it has the ability to allow water to pass through it but not soil and its contents. The material is also easily applied because it's flexible and soft. These features allows the material to fit securely around your garden's soil.

To install a silt fence, you need to dig a small trench around the area you plan to construct your garden. The source noted above, recommends that your trench be at least 8 to 12 inches deep and 1 to 2 feet wide. The bottom of the fence should sit inside the soil as well as around it for better support. The dimensions allow you to do so effectively. You also must use posts or stakes to secure the fencing material in place. Try to place the posts at least 10 feet apart to ensure that they hold the fabric in place securely. 

After you attach the fabric to the posts, you can add your topsoil, seeds and other necessities to the garden. Be sure to check the silt fencing regularly to ensure that it is still secure in the ground.
