You can make a raised bed for gardening on a budget by repurposing old pallets, which can cost as little as $0. You can also use reclaimed wood from an old fence or deck to save money.

The size of your raised bed will depend on the space you have available, but a good starting point is a bed that's 4 feet wide and 8 feet long, which can be built for around $50. This size is also a good fit for most garden tools.

To make your raised bed more accessible, consider adding a trellis or a gate, which can be made from materials like bamboo or wire, and cost around $20. This will also help to keep pests out of your garden.

By using recycled materials and planning your bed carefully, you can create a beautiful and functional raised bed for gardening without breaking the bank.

You'll need to choose a location for your raised bed, taking into account any drainage issues. The article notes that raised beds can help with drainage, especially in areas that get gulley-washer rains.

Consider the size and shape of your raised bed, and how it will fit into your garden layout. The article mentions that raised beds can help create pathways and keep weeds from encroaching on the garden beds, making them a great option for overgrown areas.

Here are some key things to keep in mind when planning your raised bed:

Why Grow?

Growing in raised beds offers many benefits, making them a popular choice for gardeners.

Raised beds can improve growing conditions by allowing you to fill them with a fertile, free-draining soil mixture, which is especially good if your garden soil is poor or heavy and prone to waterlogging.

Their limited size makes them easier to manage than open ground, and they're more accessible for gardeners with restricted mobility.

Raised beds can increase soil temperature in spring, which is great for getting veggies off to an early start.

They also allow you to match the soil to the plant, so you can grow plants that wouldn't usually thrive in your garden soil.

A raised bed can even serve as a nursery bed for cuttings and young plants.

By growing in raised beds, you can keep small plants nearer eye level, making them easier to enjoy, like flowering alpines.

Raised beds make growing crops easier, as it's simpler to practice crop rotation and easier to cover beds for protection from frost and insect feeding damage.

Here are some ways raised beds can be used to improve your garden:

  • Improve growing conditions
  • Increase soil temperature
  • Match the soil to the plant
  • Create a nursery bed
  • Keep small plants nearer eye level
  • Make growing crops easier

Getting Started

To get started with your garden, you'll need to choose the right spot. This should be a level area with at least six to eight hours of sunlight for your plants.

Sunlight is crucial for most plants, so position your raised beds in the south- or west-facing parts of your garden, away from the shade of overhanging trees.

You'll want to run your long beds north to south for even sunlight levels. This will ensure that all your plants get the light they need.

For smaller gardens, multiple smaller beds are a better option than long runs of beds. This makes it easier to manage and maintain your garden.

Widths of less than 1.5m (5ft) should allow you to easily reach the centre of the bed without having to stand on the soil.

For most plants, a depth of 45cm (18in) or more is needed. This is especially true for fruit bushes, shrubs, and small trees.

Here are some general guidelines for raised bed depth:

Aim to make paths between beds at least 45cm (18in) wide to accommodate a wheelbarrow. If needed, make paths at least 1m (3½ft) wide to accommodate a wheelchair.

Materials and Tools

To make a raised bed for gardening, you'll need the right materials and tools. You can use durable timber, such as softwood sleepers or reclaimed hardwood, pre-cut to the required lengths.

A saw is a must-have for cutting wood to size, but if you're short on time, you can have the hardware store cut the wood for you. You'll also need a drill for creating holes for each hex screw, a 1/4" drill bit, and a bolt tightener to tighten the screws and nuts together.

Here's a list of materials and tools you'll need:

  • Durable timber (e.g., softwood sleepers or reclaimed hardwood)
  • Saw (or have the hardware store cut the wood for you)
  • Drill
  • 1/4" drill bit
  • Bolt tightener
  • Electric drill and coach screws (for building timber-framed raised beds)
  • Miter Saw or Circular Saw (for cutting wood to size)
  • Power Drill (for building raised garden beds)

Keep in mind that the type of wood you use can be a hot topic, so consider using rot-resistant wood like cedar or redwood.

Should I Use Pressure-Treated Wood?

Pressure-treated wood is a common choice for outdoor projects, but it's not the only option. Lots of controversy surrounds its use, especially when it comes to chemicals leaching into the soil.

The main chemical in pressure-treated lumber is Micronized Copper Azole (MCA), which is considered safer than the older type that contained arsenic. This is a big improvement, but it's still not "certified organic".

Credit: youtube.com, Pressure Treated Wood - What Grade do you Want for your Project?

You can plant seeds a few inches away from the edge of the wood to avoid any potential issues with copper leaching into the soil. Copper is a nutrient that humans can process, and it's even found in our water.

If you're looking for a chemical-free alternative, consider using white oak or eastern red cedar, which can be sourced locally from salvaged logs. These woods are resistant to mold, pests, and outdoor wear and tear, and they last longer than pressure-treated pine.

Sealing your wood with a plant-based, food-safe wood sealer is a good idea, regardless of the type of wood you choose. This will help protect it from the elements and extend its lifespan.

Tools Needed

To build a raised bed, you'll need some essential tools. A saw is a must-have, but you can skip it if you have the store cut the wood pieces for you.

Some tools are optional, like a framing square, which can help you ensure your corners are square.

A pencil and tape measure are handy for marking the boards and holes for drilling. You'll also need a hand drill for creating holes for each hex screw.

A 1/4" drill bit is necessary for making the right-sized holes. You'll also need a bolt tightener to tighten the screws and nuts together.

Here's a list of the essential tools you'll need:

  • Saw (or have the store cut the wood pieces for you)
  • Pencil and tape measure
  • Hand drill
  • 1/4" drill bit
  • Bolt tightener
  • Framing square (optional)

A power drill is also a must-have for most raised bed constructions. You'll need it to drive the screws and nuts into place.

Best Wood Options

Redwood and cedar are the top choices for building long-lasting raised beds. They're both durable, rot-resistant, and can last at least a decade or two.

Redwood is typically found on the west coast, while cedar is more common in the eastern US. I've used heart redwood in my own raised beds, which is even denser and longer-lasting than common construction redwood.

Neither redwood nor cedar needs to be stained or sealed, but applying a non-toxic wood sealer can extend their life even further.

Softer woods like pine or Douglas fir are more budget-friendly options, but expect them to last only 3 to 7 years on average, depending on the climate.

Thicker and larger boards will make your raised garden beds more durable. For example, 2-inch thick boards will outlast thinner 1-inch cedar fence pickets.

Avoid building raised garden beds from treated lumber, unknown recycled, stained, or painted wood, or toxic railroad ties.

Look for wood products marked with "FSC" or Forest Stewardship Council certification, which ensures responsible forest management.

Materials and Tools

Hardware cloth is a must-have for gopher proofing, and it's made from strong galvanized metal that won't rust or disintegrate with time.

You can buy hardware cloth in 2, 3, or 4-foot wide rolls of varying lengths, so choose a size that fits across the bottom of your raised bed frame.

If your bed is too wide, you can combine two pieces of hardware cloth, overlapping and attaching them in the middle with heavy-duty zip ties or bits of galvanized wire.

We like to use wide-head cabinet screws to connect hardware cloth directly to the bottom of raised beds, pinching the wire between the head and the wood.

Staples can also be used, but they're not as secure as screws.

Building an inexpensive raised bed is definitely possible. You can create a beautiful and long-lasting garden bed using minimal tools and materials.

The cost of materials is a significant factor to consider. According to the author, the original cost of materials for their $100 raised bed was around $100, with cedar boards, framing angles, and hardware making up the bulk of the expense.

Prices may vary depending on your location, so be sure to factor that in when budgeting. The author notes that the price of cedar keeps increasing, so budget a little over $100 total.

The author has also provided modifications for different sizes and shapes of garden beds, including DIY raised bed garden plans for the following sizes:

These modifications can help you create a garden bed that fits your specific needs and space constraints.

Design and Layout

When designing your raised bed, consider the orientation of your garden. In the northern hemisphere, a south-facing garden is ideal, while in the southern hemisphere, a north-facing garden is best. This is because the sun's rays hit the earth at a different angle in each hemisphere.

In terms of layout, it's best to set your raised garden beds in a north-south orientation, with the shorter sides going east-west. This allows for long rows of crops to be planted north to south without shading each other out.

Before making any final decisions, test out your design by laying down rope, stakes, or other materials to get a sense of the space and how it will feel once the raised bed is in place. This will help you visualize the layout and make any necessary adjustments.

Here are some key considerations for the size of your raised bed:

Remember to also consider the pathways between your raised beds, aiming for at least 45cm (18in) wide for a wheelbarrow and at least 1m (3½ft) for a wheelchair.

4'x6'

When building a raised garden bed, the size and materials used can greatly impact the overall design and layout.

For a 4'x6' raised garden bed, you'll need to cut your boards to specific lengths. To make this happen, you'll need to purchase six 2"x6"x8' boards and cut two of them to 4' each.

Cutting boards to the right size is crucial for a sturdy raised garden bed. The other four boards will be cut to 6' each.

Using the right framing angles is also essential. For this project, you'll need 12" framing angles.

Here's a quick rundown of the materials you'll need for a 4'x6' raised garden bed:

  • 6 2"x6"x8' boards
  • 12" framing angles

Layout

Layout is a crucial aspect of garden design. A south-facing garden is ideal in the northern hemisphere, while a north-facing garden is best in the southern hemisphere.

To maximize sun exposure, orient your raised garden beds in a way that receives direct sunlight from the south in all seasons. This will ensure your plants get the light they need to thrive.

In most cases, a north-south orientation is best for raised garden beds, with the shorter sides going east-west. This layout allows for long rows of crops to be planted north to south without shading each other out.

Test your layout idea by staking out the space with rope, stakes, or other materials. This will give you a better sense of the garden's proportions and how it will feel in real life.

Spacing your garden beds is crucial for easy access and healthy plant growth. I recommend keeping them at least 28 inches apart.

Having aisles between beds allows you to move a wheelbarrow or garden cart up and down without obstruction. This makes maintenance and harvesting a breeze.

Proper spacing also prevents neighboring plants from shading each other out, especially tall crops or those using trellises. This is especially important in the height of summer when plants can become overgrown and spill into pathways.

In our own garden, we've found that spacing beds 36 to 48 inches apart works perfectly for us.

Getting Everything Level

Getting everything level is a crucial step in any DIY project. It's the hardest and most time-consuming part, but don't skimp on it.

If you don't get the first course of boards level, it'll throw off your second row of boards and the whole thing will be generally tilted. This is why it's essential to use your level and rubber mallet to get the first board level.

Removing dirt under one side or adding dirt under the other as needed will help you achieve a level surface. A hand trowel is useful here for adding or removing small amounts of dirt.

Try to secure the first board with some dirt on either side or clamps or heavy books to keep it upright and mostly in place. This will give you a solid foundation for the rest of your project.

Building the Frame

To build the frame of your raised bed, start by creating the short sides. This is easiest to do by laying out two of the cut 4×4” corner pieces on a level surface, positioning them the same distance apart as your shortest side boards.

Place the short boards on top, keeping the ends of the 2×6” boards flush with the outer edge of the corner 4×4” piece. To ensure everything is square, measure the distance between the 4×4’s at both ends.

Using 2.5 to 3-inch decking screws and a power drill, add two screws to the end of each 2×6” board, attaching them to the 4×4 below. Keep the screws at least 1” away from any edges of the board to prevent splitting.

Here's a summary of the materials and tools you'll need for this step:

Once you've completed the short sides, repeat the process for the second short side.

4'x10' x 16"

To build the frame of your 4'x10' raised bed, you'll need to account for the actual dimensions of the materials. The bed will be 16.5 inches tall, not 18 inches, due to the 5.5" height of 2x6" boards.

You'll also need to cut the corner pieces to the true height of the bed accordingly.

Measure the Boards

Measure the boards accurately to ensure a sturdy frame for your raised bed. It's surprising how often actual thickness differs from the advertised 2" measurement.

Credit: youtube.com, Framing Pro Tips

The boards I purchased, for instance, were actually 1 3/4" thick. This discrepancy may seem minor, but it's crucial for the structure's stability.

Before marking the boards, take note of the exact thickness. This will help you create a straight line along both edges, where the tip of the other board will lay flat.

Mark the thickness along both edges of the four boards to create a straight line. This is where the tip of the other board will lay flat against this board.

Once you've marked the boards, remove them and drill holes in the places you've marked.

Attach Framing Angles

Attach framing angles to create sturdy corners and seamless designs. You'll want to purchase the tallest framing angle needed to connect your two boards vertically, which are usually found in the decking department of your local hardware store.

Framing angles come in different sizes, typically 4", 8", and 12". To find the right size, place one of the framing angles in the length you've selected inside the two boards when they're stacked on their sides vertically and make sure the angle fits inside.

Attach each framing angle with the hex screw on the outside and the washer and nut on the inside. This will ensure a secure and clean connection.

Using framing angles in each interior corner means you don't have to purchase extra wood for trim, which can save you money and effort in the long run.

Here are the typical sizes of framing angles you can expect to find:

Having a partner to hold the boards steady while attaching framing angles can be a big help. This will ensure a smooth and accurate process.

Begin Other Sides

Now that you've got the short sides of your raised bed assembled, it's time to prepare the other boards. Line up two new boards along a framing angle that's already attached to a panel and make sure the edges are flush and straight. Mark holes on the two new boards for drilling.

To ensure everything is nice and square, measure the distance between the framing angles at both ends. This is a crucial step, as it will help you maintain the integrity of your raised bed.

You'll want to use 2.5 to 3-inch decking screws and a power drill to attach the new boards to the existing frame. Keep the screws at least 1" away from any edges of the board, preferably sinking it into the center of the framing angle.

Here's a quick rundown of the steps to follow:

  • Line up two new boards along a framing angle.
  • Mark holes on the two new boards for drilling.
  • Measure the distance between the framing angles at both ends.
  • Attach the new boards to the existing frame using 2.5 to 3-inch decking screws.

Remember to keep the screws at least 1" away from any edges of the board to prevent splitting. If loose boards shift around while you're working, re-adjust to bring everything back to square.

Complete 1st Corner

To complete the first corner of your raised garden bed, start by attaching two boards to the framing angle with hex screws, washers, and nuts. Having a partner to hold the boards steady is a great idea.

You'll need to cut four small lengths of 2x4 lumber, about 2' apiece, to use as corner stakes. These stakes will be driven into the ground a few inches and will stick up a little taller than your two rows of 2x8s.

Use a rubber mallet to hammer one of these stakes into the ground at one corner, then use your mallet to get your boards snug around this corner stake. Drill pilot holes and attach the long 2x8 board to the 2x4 stake using 2.5-in screws.

To ensure everything is square, use your framing square to square up all the corners. Repeat this process with the other three corners, driving in your stakes and then attaching the 2x8 boards to the 2x4s.

Here's a quick summary of the steps:

With this first corner now anchored to the ground, you can move on to building the rest of the frame. Remember to keep using your level and square to ensure everything is perfectly aligned.

Assemble Short Ends

Assemble the short ends of your raised bed frame first, as this will give you a solid foundation for the rest of the build.

To do this, lay out two of the cut 4×4” corner pieces on a level surface, positioning them the same distance apart that your shortest side boards are.

Keep the ends of the 2×6” boards flush with the outer edge of the corner 4×4” piece. To ensure everything is square, measure the distance between 4×4's at both ends.

Next, use 2.5 to 3-inch decking screws and a power drill to add two screws to the end of each 2×6” board, attaching them to the 4×4 below.

To prevent the 2×6” from splitting, keep the screws at least 1” away from any edges of the board, preferably sinking it into the center of the 4×4”.

Repeat this process for the second short side, ensuring that everything remains square and secure.

Here's a summary of the steps to assemble the short ends:

Modification: Ditch Framing

If you're looking for a simpler way to build your raised bed frame, consider ditching the framing angles altogether. You can purchase raised bed corners that fit into the slots of the frame, making assembly a breeze.

These corners are available from various suppliers, including Gardeners' Supply, which offers a clean and sleek look thanks to their thin profile and corner caps. Their cedar boards are naturally insect- and rot-resistant, making them a great option.

Oldcastle planter blocks from Home Depot are another alternative, but they won't give you the same clean lines as the Gardeners' Supply corners. However, they're stackable up to 2 feet high and made from food-safe concrete, making them a convenient choice.

Make sure to check the thickness of the boards the corners will accept, as most fit 2"-thick lumber.

Assembling the Bed

Start by laying out two of the cut 4×4” corner pieces on a level surface like a garage floor, deck, or patio. Position them the same distance apart that your shortest side boards are.

To ensure everything is nice and square, measure the distance between 4×4’s at both ends. This will help you get a good starting point for your build.

Use 2.5 to 3-inch decking screws and a power drill to add two screws to the end of each 2×6” board, attaching them to the 4×4 below. Keep the screws at least 1” away from any edges of the board to prevent splitting.

Credit: youtube.com, How To Build A Raised Garden Bed

Repeat this process for the second short side, making sure to keep everything square and secure.

Here’s a summary of the steps:

  • Lay out two 4×4” corner pieces and position them the same distance apart as your shortest side boards.
  • Measure the distance between 4×4’s at both ends to ensure everything is square.
  • Use 2.5 to 3-inch decking screws to attach the 2×6” boards to the 4×4 below, keeping the screws at least 1” away from edges.
  • Repeat the process for the second short side.

Installation and Tips

Building a raised bed can be a bit of a challenge, but getting it right is crucial for a successful garden. You'll want to start by preparing the ground below your raised bed, making sure it's flat, level, and free of excess rocks, weeds, or other debris.

It's essential to have a good setup for your kitchen garden, so don't skip this step. If the space is slightly sloped, dig out a fairly flat pad for each raised bed to ensure even water distribution.

You may need to amend and/or till the soil before setting the bed down, especially if your native soil is rocky, compact, clay, or otherwise less-than-ideal. Loosen the soil and work in some aged compost to give your plants and their roots the best chance to thrive.

To ensure your raised bed is level, use a spirit level to check the levels diagonally between the timbers as well as along their length. This will help you create a sturdy and even structure.

For deeper beds, remove any turf and the underlying topsoil, replacing with rubble or subsoil to ensure good drainage and reduce the quantity of good soil needed to fill the bed.

Here's a general potting mixture recipe to fill your raised bed: three parts organic matter, two parts sharp sand, and seven parts topsoil. For alpines, bulbs, and herbs that like good drainage, double the proportion of sand.
