Let the tree trunk into the ground
A very simple method is a long one Tree trunk to let go directly into the earth. In order for the trunk to be stable and secure, about a third of its length must disappear into the ground. The soil is then well consolidated, for example with a vibrator. The problem with letting the tree trunk into the ground is the fact that dead wood (which is what it is, after all) is always in contact with damp soil is very quickly attacked by putrefactive fungi and bacteria, which is why such a construction does not have a very long service life should.

Protect wood against rot
However, there are ways that Durability of the wood to improve and so postpone the putrefaction. This includes that you should only use hardwood such as oak or beech for such a project - these types of wood are much more resistant and therefore rot more slowly. On the other hand, soft wood such as spruce, fir or pine is not advisable - even fruit tree wood and especially birch rot very quickly. There are also various ways to protect wood against moisture:
- Filling the hole in the ground with gravel and stones instead of topsoil
- Soaking the wood with wood protection
- Treating the wood with tar
- exclusively well dried wood use
Concrete in the tree trunk
If you want to be on the safe side, concreted the tree trunk in the ground. However, even with this method, the wood is not completely protected against moisture, as the foundation also absorbs and transfers moisture. It is better to lock the trunk a few centimeters above the foundation so that the wood does not even come into contact with the ground. In addition, the concreted area could become a problem a few years later, as it is very difficult to remove. It is possible that the tree trunk above ground has long since rotted away and the concrete foundation can still hold out, making it more difficult, for example, to carry out another construction project in the same place.
Anchor the tree trunk to a base
There are various options available for anchoring the tree trunk on any surface, both indoors and outdoors. For example, you can use the following aids for locking:
- an adjustable foot
- a U-angle
- a ground anchor
- a T-connector
- a round iron
Tips
You can hide the mostly unsightly anchors behind a self-made wooden ring made of the same type of wood.
