Adjustable height garden bed box
Plans and step-by-step instructions on how to build an adjustable height Garden bed Box.
There are 26 pages in the downloadable PDF file which contain both the metric (mm) and imperial (inch) version.
There are clear plans, instructions, pictures, and drawings.
This is a multipurpose garden bed box.
You can make 1 high garden box, 2 medium height, or 3 lower boxes. Switch and change to suit – all with the same interlocking boards.
This raised garden box is very versatile and practical.
It is easy to assemble, disassemble, and change height, as the pieces slot into one another (interlock) and there is no need for any fasteners.
Overall the footprint (area) is 4ft x 4ft.
The height can be raised or lowered at will just by adding or subtracting the wall boards.
The height adjustable factor can be very useful for growing such vegetables as potatoes which can benefit from adding height in stages as the plants grow.
What size wood
I used 1×6 (25mm x 150mm) actual size boards for this project.
Wider or thicker wood can be used by following the same construction principles.
What type of wood
Use a wood that is decay resistant – i.e. suitable for outside and it’s intended application.
Some natural woods do the trick, but for the most part treated woods seem to be cheaper and more readily available.
Some treated woods have toxic chemicals in them that may get into the soil and possibly the plant life.
Some treated woods can be acceptable. Your local supplier should be able to advise on the right type of wood to use, and if you have any concerns about the treatment you can always place plastic sheet (e.g. polythene) between the boards and the soil.
The boards are 4ft (1200mm) long. How many depends on how high you want to go.
The making basically involves cutting slots into the edge of the boards at each end. The slots in one board fit into the slots in another board and that holds them together. The more boards added, the higher she goes. Easy stuff and very practical.
