How to Build Raised Garden Beds from Wood and Other Materials

In this article, we’ll take a closer look at how you can build your own raised beds using wood — the classic choice — and we’ll also touch on some other materials you might consider.

So if you’ve always wanted to build your own raised garden bed, this is the guide for you!

Recommended Types of Wood for Raised Beds

Larch: A beautiful wood that doesn’t require much treatment. Larch beds can easily last a decade or more, even with constant exposure to soil and the elements.

Hardwoods: Known for their deep, rich colors and extreme durability. Expect 20+ years of use, though they’re usually more expensive and not as beginner-friendly to work with.

Pine: A more affordable, lightweight wood that’s easy to handle. However, it won’t last as long due to soil exposure — generally about 7–10 years.

You can also use reclaimed wood or scrap pieces if they fit your design — just be aware that durability may vary. The upside? You can always replace pieces down the line.

Note: Avoid using pressure-treated lumber for raised beds. The chemicals used in the treatment can be harmful — especially if you’re growing anything edible like herbs or vegetables.

Why Use Raised Beds?

There are several key benefits to using raised beds:

• A more comfortable working height
• Helps make your garden beds a visual highlight
• Wood or metal beds can add a clean, stylish look to your yard
• Makes it easier to protect plants from pests

These are the most common benefits — and once you start using raised beds, you’ll probably wonder why you didn’t do it sooner. Want more tips? Check out our full guide to raised garden beds.

Raised Beds Made of Wood

Wood is by far the most popular material for raised beds in home gardens. It creates a natural yet elegant look and is easy to work with, even if you’re new to DIY.

It’s also widely available, easy to cut, and simple to assemble — a perfect choice for home projects.

How to Build a Wooden Raised Bed

Building your own raised bed is easier than you think — and once you’ve finished one, you might find yourself wanting to build a couple more.

Planning and Preparation

• Choose a spot with plenty of sunlight and easy access from all sides.
• Don’t make the bed too wide — you should be able to reach the middle comfortably.
• Gather all materials and tools before you begin to keep the project moving smoothly.

You’ll Need:

• 4 wooden posts (for the corners)
• Boards in your desired length and height
• A good power drill and screws
• A shovel or post-hole digger
• Optional: a moisture barrier liner to protect the inside

Step-by-Step Instructions:

1. Measure and mark the layout. Use the boards to help visualize the size.
2. Dig holes for the corner posts — make them deep enough for stability.
3. Set the posts in the holes and pack the soil tightly around them.
4. Attach the boards to the outside of the posts, starting from the bottom and working up.
5. If desired, attach a liner inside the walls to help preserve the wood.
6. Add a drainage layer at the bottom, then fill with soil.

It might sound too simple, but that’s really all it takes! No expert skills are required, and it’s a great DIY project — even for beginners.

Pro tip: For a rustic twist, try using pallet collars or reclaimed wood. They can add unique character to your garden.

Raised Beds Made of Metal

Metal raised beds are extremely durable and add a bold, distinctive look to your garden. Depending on the type and finish, they can look rustic or sleek and modern.

Most metal beds are sold as pre-made kits that you simply assemble in place — an easy DIY option.

Tips for Assembly:

• Make sure the metal panels are properly aligned and connected at the corners.
• Many kits include rods or wires that reinforce the structure — tighten them securely to prevent bowing.
• Check each layer before moving on to the next to ensure it stays level.
• Use a rubber mallet for adjustments to avoid damaging the metal.

You’ll find metal beds in a wide range of styles. You can even have one custom-made if you have a specific design in mind — or contact a local metalworker for something truly one-of-a-kind.

Steel, Iron, or Other Metals – Which Is Best?

There are several types of metal you can use, depending on your taste and needs.

Corten steel creates a rustic, weathered look as it naturally oxidizes.
Stainless or coated metals give a cleaner, modern look and require less maintenance.
Iron can be a good option but is more prone to rust and may need extra care over time.

Raised Beds Made from Other Materials

Besides wood and metal, you can also build raised beds from a variety of alternative materials — though some may be trickier to work with.

Stone

Building a bed from stone can look absolutely stunning. Natural stones offer a more organic, old-world feel, while using the same pavers as your patio can create a cohesive design throughout your garden.

Just make sure the structure is stable and designed to handle the outward pressure from the soil and plants. Otherwise, it might collapse over time.

Use either prefab stone kits or mortar them securely in place for best results.

Composite

Composite is a wood-look plastic that’s lightweight, durable, and weather-resistant. It won’t rot, won’t attract pests, and requires zero maintenance — perfect if you want a set-it-and-forget-it option.

It’s easy to work with and has become a popular alternative to traditional wood.

Things to Keep in Mind When Building Raised Beds

No matter what material you use, there are a few things to consider for the best results:

• Location is key: Make sure your plants get enough sunlight.
• Pest protection: Consider adding a slug/snail guard to keep out garden pests.
• Moisture liner: If you want one, it’s best to install it before filling the bed.
• Drainage: Add a gravel or stone layer at the bottom to prevent waterlogging.
• Aesthetics: Choose a shape and style that complements your garden. Circular beds or unique layouts can add extra flair.

Do You Need Any Extras for Your Raised Bed?

There are a few helpful add-ons that can make raised gardening even easier — from pest barriers to trellises and protective covers.
