A he althy root system is also essential for the Nordmann fir. Invisible to our eyes, it unfolds and spreads in the ground. We replace assumptions about whether it branches out and penetrates far into the depths with facts.
How is the root system of the Nordmann fir structured?
The roots of the Nordmann fir consist of a deep taproot that provides stability and nutrient supply, as well as lateral roots that develop over time. Transplanting is difficult because the taproot can be easily damaged.
A taproot appears early
The Nordmann fir initially develops a taproot when it is young. This is a root that grows vertically directly under the trunk and becomes longer and longer over the years. It can adapt flexibly to the existing surface and thus avoid one or two obstacles. For example, larger stones that block her straight path.
Benefits of deep roots
With its long roots, the fir tree has two advantages: It is therefore better connected to the ground, so that no storm can easily uproot it. The deep roots also facilitate the supply of water and nutrients, which is why a fully grown Nordmann fir can usually get along well without watering or fertilizing.
Side roots will follow a little later
The taproot is undoubtedly of crucial importance for the Nordmann fir, but alone it cannot support the conifer. That's why many additional lateral roots develop over time. This allows the fir tree to penetrate large areas of the ground, thereby ensuring its survival.
Taproots make transplanting difficult
The taproot of the fir tree has one disadvantage, but ideally this does not have to come into play. It makes digging up the tree very difficult when, as with transplanting, the aim is not to damage the roots.
- find a permanent location for them right from the start
- Don't transplant fir trees if possible
- only young trees can be easily dug up (up to approx. 1.6 m high)
- If necessary, cut off the tip of larger specimens
Christmas trees with cut roots
You should not plant a Nordmann fir that previously stood as a Christmas tree in the living room in the garden. Fir trees that are offered in pots are vital for a while, but have no chance of staying alive permanently. The reason is that when planting in the pot, the long root system is shortened for reasons of space. However, an intact taproot is essential for the continued existence of the tree. It can no longer recover and will not grow back.
Possible damage from the roots
The long taproot and the strong lateral roots can develop a force that can damage pipes, masonry or sidewalks in their area of spread. Therefore, make sure there is enough planting distance.
