Raised flower/ vegetable beds can be a great way of avoiding the nuisance of weeds invading your plants and also helps avoid creepy crawlies finding their way in as they are raised from the ground and can also be protected with membranes to keep out unwanted visitors. As well as these benefits, they also look great; giving a rustic finish to your garden with the use of wood – plus, it saves you crouching down to the ground to tend to the plants too!
This how-to guide will help give you a rough idea of how the process of building of a raised bed works, the types of wooden sleepers we have available as well as handy tips along the way.
What you’ll need:
Tanalised Pine Sleepers
These pine sleepers measure 2.4m x 20cm x 10cm. This is a softer timber pine wood making it the lightest to handle, easier to fix to and can be cut easily by a hand saw. They also tend to be more uniform (you can expect 4 even faces). This wood has also been tanalised which gives extra protection and longevity; treated to last at least 10 years.
You could buy 6 of these to make a flower/ vegetable bed measuring 2.4m x 0.8m and cut 2 lengths of wood in half for the shorter sides. This would make a two-tier high raised bed.
Reclaimed Grade A Sleepers
These measure approximately 2.6m x 25cm x 15cm but sizes can vary as these sleepers are actually from old railways. These sleepers make the best value for money; they look great and they’ll last the longest. They have an old, rustic, worn look which is very popular among people looking to add something a bit different to their garden. However, a disadvantage of these is that they tend to seep tar, especially during sunny periods, so some people are put off using them for planting in.
Oak sleepers are also very popular, measuring 2.4m x 20cm x 10cm. They are are a hardwood sleeper that can still be hand sawn or machine sawn would be easier. This wood is untreated and you can expect at least one of the faces of the sleeper to have a rustic edge. When these are left untreated over time they’ll turn from an almost golden colour to a wonderful silver colour.

Weed Membrane – We sell different types of this in-store but can be viewed on our website. This can be laid on the ground to help prevent the growth of weeds coming through and can also help prevent small creatures working their way up through the soil! View our range here.
Drainable Hardcore Material – This could either be scalping or crushed concrete. Putting these down will help the drainage of water and can also prevent rotting of the sleepers when placed underneath.
Place down your sleepers to see where looks best
Once your sleepers have been sawn down to size, place them down on the desired area of your garden. You should consider areas of the garden that get a certain amount of sunlight. Once you’re happy with where they are, mark this area by lightly digging a spade around the outside perimeter.
Dig out your desired area
You can now remove the sleepers and begin to dig at least 3cm into the ground of the entire area of these markings. Make sure you remove any roots or stones, and use your spirit level to ensure the ground is level.
Place the sleepers back into the ground within this area and use your spirit level to ensure all sides are level.
(Optional) Prevent those pesky weeds!
This step is if you’re using weed fabric. Carefully remove the sleepers from where they are and use the dug out area to measure how much fabric you’ll need to cover the entire area. This may mean using two layers to ensure all under soil is covered. Our Weed Fabric rolls measure 14m x 1m. This will allow water to drain out from the rain and will also prevent weeds from growing through. Cut the fabric with heavy duty scissors and as an extra option, you can pin down this fabric using nails, although the sleepers should hold this down.
