5 BEST Materials to Put Under My Raised Garden Bed

Healthy plants in a raised garden bed

It’s easy to see why so many people love raised garden beds. They make it easier to care for your plants and maximize garden space. In addition, raised garden beds help with drainage, reduce soil compaction, keep rodents and other pests from burrowing in, and help prevent weeds. If they’re built correctly, raised garden beds can last many years. Proper building means knowing which materials work best for lining under a raised garden bed.

Quick note: If you don’t have the time to take care of your plants or need help controlling weeds in your lawn, The Grounds Guys can take care of it for you. We offer a wide range of lawn care services to maintain the health and aesthetics of your garden!

What to Put Under Raised Garden Beds

The materials you put under raised garden beds create a barrier between the garden’s soil and the ground. The proper material can stop weeds from poking through, keep out toxins, and ensure that pests stay in the ground and aren’t feasting on your garden!

Depending on your budget and gardening goals, you can line the bottom of your raised garden beds with wide-mesh hardware cloth, stainless steel mesh, landscape fabric, burlap sack, or newspaper/cardboard. Below are some details on the benefits of each.

Wide-mesh Hardware Cloth

This material keeps weeds and burrowing animals out, yet earthworms can still get through. Earthworms are nature’s gardeners, they aerate and enrich the soil for the benefit of your plants. Staple the cloth to the bottom of the garden bed frame during the construction process. Once in place, it should serve its purpose for many years to come.

Stainless Steel Gopher or Rat Mesh

This durable material is designed to keep burrowing animals out. Staple it in place (attach to the bottom of the bed frame) to ensure it doesn’t shift around.

Landscape Fabric

If you’ve had a weed problem in your flower beds, landscape fabric is effective at keeping unwanted weeds from overtaking your plants. The fabric provides an effective barrier against weeds, but allows water and other beneficial nutrients to reach your plants

Burlap Sack

Do you have an old potato sack on hand? This material makes a great weed stopper when stapled to the bottom of a garden bed frame. Simply cut the sack to the dimensions of your bed(s) and secure it to the bottom for an effective weed barrier.

Newspaper or Cardboard

Even simple, cheap materials can block weed growth from below your garden beds. You can simply lay them on the ground before setting your garden beds on top of them. Alternatively, you can place sheets of newspaper or cardboard toward the top of your planters for the added moisture-retention benefit, similar to what mulch provides.

Best Soil for Raised Garden Beds

One of the advantages of gardening with a raised bed is you’re in control of the soil. It’s a significant benefit for homeowners with yards of clay or hardpacked soil, tree root issues, or concerns about pollutants in the ground. Soil is the foundation of your garden, and you want it to be healthy so you can set your plants up for success! We recommend buying high-quality, nutrient-rich soil in bulk. Or, you can make a soil mix with equal parts topsoil, organic materials (leaves, composted manure, ground bark), and coarse sand.

Raised Garden Bed Ideas

You can build your raised garden bed however you see fit. Feel free to get creative or stick to a simple design; it’s your choice! Below are some raised garden bed ideas you can use for inspiration.

Built-in raised beds: You can build a raised bed with brick or wood and put it in the best place for sun or shade (depending on the plants and flowers you choose). If you select a wood design, ensure it’s intended for outdoor use and holds up well to the elements (sun and rain). If not, you’ll find yourself replacing it every year.

Grow bag raised beds: Using grow bags is a simple way to have a raised garden bed in minutes. Grow bags are great because they don’t freeze solid, so the soil in them will defrost quickly during the colder months of the year. Trough beds: Animal feeding troughs can be another easy way to create a raised garden bed. The metal gives them an attractive industrial look, and they conduct heat well, which will warm the soil in the spring. A trough also provides a sturdy foundation and effective weed barrier for your raised bed.

Raised beds from recycled materials: From cinder blocks to concrete blocks and milk crates, you can use various recycled materials to build a garden bed. Plants that thrive in alkaline soil are a good option for a concrete bed.

These are just a handful of raised garden bed ideas. Repurposing materials into something useful is always a great option, but feel free to use familiar materials like brick, wood, and steel.

How to Build a Durable Raised Garden Bed

When you learn how to build a raised garden bed, you can’t help but get excited. The initial cost varies depending on the design and materials used. However, they’re easy to maintain once in place, and they provide many benefits! Of course, building a durable raised garden bed will vary, but there are some basic instructions to follow. For example, you’ll want to create a garden bed at least 6 inches high. The bottom line is to build a garden bed that provides easy access to your plants and gives the roots plenty of space to grow.

Be sure to prepare your location. First, make sure the area you choose is suitable for the plants and/or flowers you intend to grow. Some plants and flowers do better in full sun, while others only require partial or very little sun, so keep this in mind when picking the location for your garden. Once you’ve chosen the site, mark the area for your garden bed and remove the grass from this area. Then, place the frame in position and create an outline with a shovel. Setting the bed on the ground rather than concrete or another hard surface allows for proper drainage and root growth.

Benefits of Lining Your Raised Garden Bed

Raised garden bed lining isn’t mandatory to have healthy growing plants.

But adding raised garden bed lining does provide benefits. Many experienced gardeners recommend lining raised beds for these reasons:

  • It provides insulation for the soil and helps control temperature fluctuations.
  • It helps with soil retention.
  • It separates weeds from seeds.
  • It can drive away pests like gophers and moles that can damage your plants.

Final Raised Garden Bed Tips

As a final reminder, avoid lining your garden beds with plastic. Doing so prevents drainage and could drown your plants’ roots with too much water. If you have a weed and pest problem, consider installing a combination of metal mesh and fabric or hardware cloth and cardboard to address both issues simultaneously.
