Creating and maintaining a raised garden bed can be one of the most rewarding gardening jobs you can do. Not only is there a sense of fulfilment after building your garden bed, but you also end up with something that thoroughly complements your outside space.
Whether you’re a seasoned gardener or are taking your first steps in your horticultural journey, building a raised bed using railway sleepers is a durable, versatile and aesthetically pleasing way to add charm and character to your garden. Let’s explore how you can use railway garden sleepers to give you a garden bed that you can be proud of for years to come.
Why Use Railway Sleepers for Raised Garden Beds?
Garden railway sleepers provide the perfect foundation for raised flower beds. Being made from high-quality timber, these structures offer excellent longevity when properly treated and maintained, making them ideal for containing soil and withstanding weather conditions year-round.
At Heritage Products, our pressure-treated softwood sleepers are completely safe for children, pets, plants, and insects, giving you peace of mind while ensuring that your garden is going to be gifted with a quality addition.
The natural wood aesthetic complements any garden style, from traditional cottage gardens to contemporary and streamlined outdoor spaces. Plus, working with railway sleeper planters is surprisingly straightforward, even for beginner gardeners.
What Do You Need for a Sleeper Garden Bed?
Before starting your project, gather these essential materials:
- Pressure-treated railway sleepers (calculate perimeter length plus extras for corners)
- Coach screws or galvanised bolts for securing corners
- Wooden stakes or metal spikes for ground anchoring
- Spirit level for ensuring even installation
- Drill with appropriate bits
- Screwdriver (PZ2)
- Measuring tape
- Pencil for marking
- Spade for ground preparation
For those preferring a simpler method, consider our ready-to-assemble raised bed sleeper kits, which include everything needed for quick installation.
How to Build a Raised Garden Bed
Step 1: Choose Your Location
Choose a location receiving sufficient sunlight for your chosen plants. Mark out your desired bed dimensions using stakes and string, ensuring you can comfortably reach the centre from all sides. A width of 1.2 metres works well for most gardeners.
Step 2: Prepare the Ground
Clear the marked area of grass, weeds, and any debris. Dig a shallow trench approximately 5-10cm deep around the perimeter. This foundation ensures your sleepers sit level and stable.
Step 3: Lay the First Course
Position your first layer of railway sleepers in the prepared trench. Use a spirit level to ensure they're perfectly horizontal.
Step 4: Secure the Structure
Drive wooden stakes or metal spikes through the sleepers into the ground at regular intervals, particularly at corners. This anchoring secures the foundation and prevents excessive movement over time.
Step 5: Add Height
For deeper beds, stack additional sleeper layers. Secure each course using coach screws at corners, drilling pilot holes to prevent wood splitting. Stagger joints between layers for maximum stability.
Step 6: Conduct the Final Checks
Ensure all connections are tight and the structure feels solid. Your raised bed should be sturdy enough to contain the weight of the soil when filled.
Filling Your Raised Garden Bed
Here's how to create the perfect soil foundation:
Bottom Layer
Add a 10-15cm layer of coarse material like shingle or stones. This prevents waterlogging whilst allowing excess moisture to drain away.
Middle Layer
Fill the majority of your bed with quality topsoil mixed with compost. This combination provides essential nutrients whilst maintaining good soil structure.
Top Layer
Finish with premium compost or growing medium for immediate planting. This nutrient-rich layer gives your plants the best possible start.
Railway Sleeper Garden Ideas
Beyond basic rectangular beds, railway sleepers offer endless design possibilities. Consider tiered planters for sloped gardens, an assortment of vegetable patches, or curved sleepers for softer lines. Consider also integrating them with one another around the garden perimeter for a consistent, streamlined aesthetic. Oak railway sleepers provide premium durability for statement features, whilst standard pressure-treated sleepers work perfectly for everyday gardens.
How to Maintain Raised Garden Beds
Regularly check your sleeper structure for any loose fixings. Remove accumulated debris from drainage areas and top up growing medium annually as it naturally settles and decomposes.
