Garden edging not only finds a neat, finished look to your outdoor space but also helps define borders and split different areas.

One of the most popular choices for edging is timber sleepers due to their durability, rustic charm, and versatility.

In this guide, I’ll walk you through the step-by-step process of how to lay sleepers for garden edging, helping you create a sturdy and attractive border that will enhance your garden design.

Why Choose Sleepers for Garden Edging?

There are several options when it comes to garden edging, from metal and plastic to brick and stone. But garden sleepers have their own unique advantages:

• Durability: Whether you choose pressure-treated sleepers or reclaimed railway sleepers, they are highly durable and resistant to weather.
• Natural Appearance: Timber sleepers offer a rustic, natural look that blends well with almost any garden style.
• Versatility: Sleepers can be used for straight, curved, or even raised garden edges, giving you a range of design options.

If you’re looking for a solution that combines practicality with aesthetic appeal, wooden sleepers are a fantastic choice.

What Tools and Materials Will You Need?

Before you start laying your garden sleepers, it’s essential to gather all the necessary tools and materials. Here’s what you’ll need:

Materials

• Timber sleepers (choose from oak sleepers, pressure-treated timber, or reclaimed railway sleepers)
• Gravel or sand (for the base layer)
• Fixing stakes or metal pins
• Screws or brackets (if stacking or joining sleepers)

Tools

• Spirit level
• Measuring tape
• Saw (for cutting sleepers to fit)
• Mallet or hammer
• Drill and screws (for fixing)
• String line (for marking)

Don’t forget to wear gloves and other protective gear when handling the sleepers, as they can be heavy and rough.

How to Lay Sleepers for Garden Edging? – Step-by-Step Guide

Now that you’re prepared, let’s move on to the most important part – laying sleepers for your garden edging. Follow these steps to ensure your edging is strong and looks great.

Step 1: Measure and Mark the Area

Begin by measuring the area where you want to place your garden edging. Use a measuring tape and mark the perimeter with a string line or garden hose.

This gives you a clear visual of where the sleepers will go and ensures the layout is aligned. If your design includes curves or corners, mark these areas accurately.

Step 2: Preparing the Ground

Next, prepare the ground by clearing away any weeds, stones, debris or grass edge near wall. You’ll need to dig a trench deep enough for the sleepers to sit securely – usually around 1/3 of the sleeper’s height should be buried underground.

The trench will not only hold the sleepers in place but also ensure stability.

• Dig the trench along the marked area, ensuring a consistent depth.
• Lay a base layer of gravel or sand for:
  • Better drainage.
  • A solid, level foundation for the sleepers.

This step ensures the sleepers are less likely to move or shift over time.

Step 3: Placing and Leveling the Sleepers

Now it’s time to place your garden sleepers into the trench. Carefully position them, making sure they fit within the marked area.

• Use a spirit level to check that each sleeper is even.
• Adjust the gravel or sand base underneath the sleepers if needed to make sure they are perfectly level.

Leveling the sleepers is crucial for a neat and professional finish. Take your time during this step to ensure all sleepers are sitting flat and aligned.

Step 4: Securing the Sleepers in Place

To make sure the sleepers stay in place, you’ll need to secure them properly:

• Hammer stakes or metal pins into the ground next to each sleeper.
• Attach the sleepers to the stakes using screws or brackets.
• For stacking sleepers:
  • Drill holes through the sleepers.
  • Use long screws or bolts to secure them together.

At corners or joints, using metal brackets will give additional support and keep the sleepers aligned.

Step 5: Cutting Sleepers for Corners or Curves

If your design includes curved edges or corners, you may need to cut some sleepers to size.

• Measure and mark the areas where the sleepers need to be cut.
• Use a saw to carefully trim the sleepers to the required length.
• Sand the cut edges to smooth them and avoid splinters.

This step allows you to customize the sleepers to fit the exact design of your garden, ensuring they sit perfectly in place.

Step 6: Backfilling and Finishing

Once the sleepers are secured, it’s time to backfill the trench to stabilize the edging:

• Backfill the trench with soil, gravel, or sand around the sleepers.
• Compact the backfill using a tamping tool to keep the sleepers stable.

For a more finished look, consider painting or staining the sleepers with a weatherproof treatment to protect them from the elements.

Step 7: Final Checks

Before finishing the project, double-check that all sleepers are level and securely in place. Make any final adjustments as needed to ensure the edging is straight and even.
