Starting a raised garden bed doesn’t have to be expensive. In fact, with a little creativity and some upcycling, I can build one for next to nothing! Raised garden beds offer a fantastic way to grow vegetables, flowers, and herbs while keeping my garden tidy and easy to manage.

In this guide, I’ll explore 6 of the best inexpensive raised garden bed ideas using budget-friendly or even free materials. I’ll also walk through step-by-step building instructions, where to find cheap supplies, and how to fill the bed without breaking the bank.

Let’s get started!

What Are the Benefits of Raised Garden Beds?

Before diving into the ideas, here’s why raised beds are such a great investment:

• Better Soil Quality – I can control the soil mix for healthier plants.
• Improved Drainage – Perfect for wet UK weather, preventing waterlogging.
• Easier to Maintain – Less bending down, making gardening more accessible.
• Pest & Weed Control – Reduces weed growth and keeps slugs at bay.
• Ideal for Small Spaces – Perfect for urban gardens, patios, or balconies.

6 Best Inexpensive Raised Garden Bed Ideas

Here are my top DIY cheap solutions for building raised beds on a budget:

1. DIY Pallet Raised Garden Beds

Pallets are one of the cheapest ways to make raised beds in the UK because they are often free or low-cost.

Where to Find Free Pallets?

• Local garden centres or nurseries.
• Construction sites (with permission).
• Online marketplaces like Freecycle or Facebook Marketplace.

How to Build a Pallet Raised Bed:

1. Find a sturdy pallet – avoid those treated with chemicals.
2. Disassemble the pallet (if needed) using a crowbar.
3. Arrange the planks into a rectangular frame and secure them with nails.
4. Line the inside with cardboard to prevent weeds from growing through.
5. Fill with compost and soil, and start planting!

Tip: Stain or paint the wood to extend its lifespan.

2. Repurposed Wooden Crates or Old Furniture

Using old wooden crates, dresser drawers, or bookshelves is another zero-cost way to create raised beds.

Where to Get Free Crates or Furniture?

• Supermarkets and fruit markets often discard wooden crates.
• Charity shops sometimes have cheap or free damaged furniture.
• Skip diving (responsibly) can be a great way to find old drawers.

How to Turn a Dresser into a Raised Bed?

1. Remove the drawers and arrange them at different levels.
2. Drill drainage holes in the bottom.
3. Line them with landscape fabric or plastic to hold soil in place.
4. Fill with soil and start growing vegetables!

Tip: Stack multiple crates for a tiered raised bed effect.

3. Brick, Stone, or Concrete Block Raised Beds

If I have leftover bricks, stones, or concrete blocks, I can use them to build a raised bed without spending a penny!

Where to Find Cheap Bricks?

• Reclamation yards or demolition sites.
• Websites like Gumtree or Freecycle.
• Local building projects with leftover materials.

How to Build a Brick Raised Bed?

1. Choose a level site for the bed.
2. Lay bricks in a rectangle, stacking them two to three rows high.
3. Fill the structure with compost and soil.
4. Optional: Use mortar to secure the bricks.

Tip: No mortar? No problem! Dry-stacked bricks work just as well.

4. No-Build Raised Beds with Logs or Straw Bales

Logs and straw bales can be used as instant raised beds – no tools required!

Logs: Ideal for rustic gardens and can be found for free in woodlands or through tree surgeons.
Straw Bales: Cheaper than wood and can compost into the soil after a season.

How to Use Straw Bales?

1. Arrange the bales in a rectangle.
2. Fill the centre with compost.
3. Start planting directly into the bale!

Tip: Straw bales last for about one growing season, making them a temporary but eco-friendly option.

5. Metal Raised Beds from Old Roofing Sheets

I can use corrugated metal roofing sheets or scrap metal to build a long-lasting raised bed.

Why Use Metal?

• Resistant to rot, unlike wood.
• Keeps soil warm, extending the growing season.
• Looks modern and stylish in urban gardens.

How to Build a Metal Raised Bed?

1. Cut metal sheets to size and secure them with wooden corner posts.
2. Reinforce the edges with screws or zip ties.
3. Line with cardboard or weed fabric before adding soil.

Tip: Use rust-proof paint to prevent corrosion.

6. Fabric Grow Bags & Large Containers

If I don’t have space for a traditional raised bed, grow bags and large containers are an easy alternative.

Best Budget Options:

• Heavy-duty fabric grow bags (£5–£10 each).
• Plastic storage bins with drainage holes.
• Recycled bathtubs or sinks.

Tip: Elevate containers on bricks to improve drainage.

What Is the Cheapest Way to Make Raised Beds in the UK?

• DIY is cheaper than store-bought options, which often cost £50 or more per bed.
• Where to find free or low-cost materials?
  • Recycled wood, bricks, or pallets from Freecycle, Gumtree, or local skips.
  • Free soil and compost from local council composting schemes.
• Budgeting for essential supplies:
  • Second-hand nails, screws, and wood treatments can often be found at charity shops or car boot sales.
