I am just in the process of designing my garden and have opted to use sleepers throughout from containing baorders to retaining soil.
The retaining walls will be 7 meters long and 0.8m high.
I want the sleepers to remain as new looking as possible so staining may be
I know that Pine will have 4 straight edges which will help when stacking and are also lighter.
The questions i have is which sleepers would you use Oak or Pine for the retaining wall?
Can you stain Oak once it has weathered into its silver/grey form?
I need to order over 150 so the price difference between a hardwood and softwood is key, however i want to make the right decision for the long term.
