If you have a garden, you should also have a composter. But why buy it expensive when you can build one out of wood yourself? Here is a guide.

wooden composter

If you compost kitchen and garden waste such as green waste and leaves on your own property, this has two major advantages: on the one hand, you no longer have to pay as much garbage fees and, on the other hand, you produce a high-quality and completely natural fertilizer for your garden , So you save twice.

The simplest solution for a compost heap is a simple wooden or wire rack from the hardware store, which is usually not very expensive. But optically and practically, these containers are not exactly ideal. You can of course also invest in a thermal composter that looks more appealing. Unfortunately, it is also very expensive. But why buy one if you can build a wooden composter yourself? After all, such a composter is quite simple to set up, so that even less talented do-it-yourselfers should have no problems building it themselves. With the following instructions it will definitely work.

Material for building a wooden composter

To implement a simple wooden composter, you need a total of 20 boards with a length of 100 cm, a width of 10 cm and a thickness of 4 cm. It is best to choose a robust and weather-resistant type of wood, even if it is a little more expensive. Larch, for example, is particularly suitable for construction, since you no longer have to impregnate this wood. If you use other woods, you must protect them from weathering with a wood preservative.

In addition to the wooden boards, you also need some wire mesh and preferably also squares with a thickness of 5 x 5 cm. In addition to a jigsaw, you need a meter and a pencil for marking on tools.

Instructions for building a wooden composter

➥ Step 1:

First of all, it's about cutting the wooden boards. With 18 of the 20 boards, you have to cut out a cut-out on the lower edge and do this on both sides. The neckline is 4 cm high and 2.5 cm wide. The distance to the outer edges of the board must be 5 cm each.


If you use boards with a different size, make the cut-outs so that they correspond to the width of the board thickness and are as high as a quarter of the board width.

2 Step 2:

Cutting the boards takes up most of the time. So you've already done most of it. Now it's time to assemble the composter. Place the two boards without a cut lengthwise on the floor. Then place two boards across it so that the cutouts snap into place. The next two boards are placed on it again lengthways, then another two are arranged transversely. Now proceed layer by layer until all 20 boards are installed.

3 Step 3:

Then place the squared timber in the corners to give the composter even more hold. However, it is not necessary to screw the individual boards together, because the cutouts should already have sufficient stability due to the cutouts.


By simply plugging them together, you can make the container larger or smaller at any time. It can therefore be used flexibly and can be rebuilt at lightning speed. Reading tip: Implement compost - This is how it's done.

4 Step 4:

Finally, it is best to line the floor with wire mesh so that voles cannot penetrate from below.
