Do I Need to Line My Raised Garden Bed?

The Benefits of Raised Garden Beds

Raised garden beds have become increasingly popular among gardening enthusiasts for a variety of reasons. They offer numerous benefits such as improved soil quality, better drainage, reduced weed growth, and easier access for planting and maintenance. Whether you are an experienced gardener or a beginner looking to start your own garden, raised beds can be a fantastic addition to your outdoor space.

The Purpose of Lining in Raised Garden Beds

Lining refers to the practice of placing some form of material at the bottom and sides of the raised bed before adding soil. This lining serves multiple purposes depending on the materials used:

1. Weed Prevention

Placing a liner at the base of your raised bed helps prevent weeds from infiltrating your garden by creating a barrier between the existing soil and new bedding soil that you add when setting up your garden bed.

2. Soil Retention

Certain types of liners like landscaping fabric or geotextile cloth help retain moisture within the soil while still allowing excess water to drain out properly. This is particularly beneficial if you live in an area with heavy rainfall or have poor-quality soil conditions.

3. Pest Protection

Using specific liners like hardware cloth or wire mesh can effectively deter burrowing pests such as gophers, moles, and rodents from damaging your crops by creating an additional physical barrier against their entry into the growing area.

Liner Options for Your Raised Bed

When it comes to choosing a suitable lining material for your raised garden bed, several options are available depending on your specific needs:

1. Landscape Fabric/Weed Barrier Cloth

One popular choice is landscape fabric or weed barrier cloth which allows water and air to pass through while blocking weed growth. This can be an excellent option for keeping weeds at bay, especially if your garden bed is placed on top of existing grass or soil prone to weed sprouting.

2. Plastic Sheeting

Using plastic sheeting as a liner provides good moisture retention but may hinder drainage if not adequately perforated. It is essential to ensure proper drainage holes are made when opting for this type of lining material.

3. Geotextile Cloth

Geotextile cloth is a permeable fabric that allows water to drain freely while retaining the soil within the raised bed structure. It offers great versatility and durability in various weather conditions.

4. Hardware Cloth/Wire Mesh

For protection against burrowing pests, hardware cloth or wire mesh with small openings can be used as a physical barrier at the base of your raised bed before filling it with soil.

Considerations Before Lining Your Raised Garden Bed

While there are potential benefits to lining your raised garden bed, it’s important to consider a few factors before making your decision:

1. Soil Type and Drainage

If you already have well-draining soil in your garden, using a liner might impede proper water drainage instead of helping it. Consider whether adding a liner would benefit or hinder the natural drainage properties of your existing soil.

2. Existing Weed Situation

Evaluate the current state of weeds in your gardening area before deciding on using landscape fabric or another weed barrier cloth. If you have minimal issues with weeds, these materials may not be necessary and could potentially restrict root growth for certain crops.

3. Pest Infestation Risk

Assess whether pests like gophers or moles pose significant risks in your area by digging into your garden beds. If pests are a known problem, using hardware cloth or wire mesh as a liner can help protect your plants from these destructive creatures.


In summary, the decision of whether to line your raised garden bed depends on various factors such as soil type, weed situation, and pest risks. While lining materials like landscape fabric and geotextile cloth offer benefits such as weed prevention and improved moisture retention, they may not be necessary in all situations. Consider the unique requirements of your garden before deciding on the appropriate lining method for your raised bed – and get ready to enjoy an abundant harvest from your thriving plants!
