Oak Railway Sleepers are ideal for building raised garden beds.
What are the advantages?
Raised softwood / oak sleeper beds are more productive per square foot because plants can be spaced more closely together. This is because you don’t need to leave spaces to walk through, because you don’t need to ever step on the garden bed. Having a higher density planting also has the advantage that the plants growing there will shade out bare soil, making it harder for weeds to grow there. There most important benefit of raised garden beds is productivity.
Raised garden beds are at least twice as productive as a conventional garden.
