For the inside of a raised bed, the classic compost layering is best, but pure potting soil can also be filled in such a bed box. For the outer edging, you can use a wide variety of materials, which not only differ greatly in their properties, but also in their price.
Raised bed borders are usually made of wood
Suitable materials for the raised bed edging
Classic borders for raised beds consist of the following materials:
wood
Raised beds made of wood should be made of hardwood such as larch, as this is particularly weather-resistant and therefore durable. On the other hand, wooden raised bed frames made from Euro pallets are cheaper (and easier to build).(29.99€)
stone
Stone raised beds can be built from both natural and concrete stones and are considered to be particularly stable and durable. As a cheap alternative, you can also use bricks, paving stones or plant stones. Shaft rings are also very suitable for edging a raised bed.
gabions
These are wire baskets that can be filled with a wide variety of materials and used as a border. They are usually made of galvanized steel and are very durable.
metal
Corten steel is particularly suitable for raised bed edgings made of metal, as it is particularly durable. It also looks very interesting due to its surface and makes the raised bed an eye-catcher in the garden or on the terrace.
plastic
Raised bed edgings made of plastic are particularly light and are therefore particularly suitable for balconies and terraces, where you have to pay attention to the total weight of the raised bed due to the statics.
No matter which material you choose: You should definitely line the raised bed from the inside with a waterproof foil or fleece so that the moisture from the filling cannot penetrate the border and destroy it over time.
What prices do you have to expect for an enclosure?
The mounts mentioned are very different in terms of cost, and they also vary greatly within a group.
wood
Raised beds made of wood can be built cheaply for 50 to 100 EUR, but then they are made of inferior and therefore less durable wood. High-quality hardwood for a raised bed costs around EUR 300 to EUR 400, depending on the size.
stone
Stone raised beds can vary in price from 50 to 100 EUR to several thousand EUR, depending on the types of stone you want to use and the tools or construction machinery you need. Gabion baskets as a border for the raised bed (which can be filled with field stones, for example) are available from around EUR 100.
metal and plastic
Metal and plastic borders for raised beds are available very cheaply from around 100 euros.
tips
You can get a raised bed particularly cheaply if you upcycle old objects such as a bathtub and - instead of throwing them away - give them a new purpose.
