Richly colored Korean firs speak the language of a good supply. Their root system is responsible for this, which does its work day after day far from our eyes. How exactly does the root system develop in the soil? And can we make a contribution to ensure that it is in the best possible position.

The Korean fir forms extensive roots over time

Korean fir has many fine shallow roots

The Korean fir forms a finely branched root system that basically does not reach far into the depths. It can be found just below the surface of the earth. Since, if necessary, the individual trees can also form deeper roots, one speaks of a so-called heart root.

Soil quality for good root formation

So that the fine roots can develop unhindered, the soil must not slow them down. When planting this fir, pay attention to the following aspects:

  • loose and well-drained soil is ideal
  • more sandy than loamy
  • heavy, compacted soil should be avoided
  • alternatively improve with large-area addition of sand

Extensive root system

The root system of the Korean fir keeps pace with the above-ground growth and spreads widely. This enables the coniferous tree to supply itself with nutrients and water on its own. Fertilizing with a special fir fertilizer is only recommended for poor soils.

A tree with so many shallow roots can suffer from water starvation during long periods of drought. This can lead to discoloration of the needles and even loss of needles, which is easily mistaken for a disease. Support the root system with the hose on hot days. The root area should never dry out completely.

Danger for paved areas and lines

A root system that spreads so far can cause damage that nobody is aware of when planting. The roots, which are just below the surface of the earth, can push up paving slabs if the planting distance is not correct. To what extent lines can also be affected depends on how deep they run.

Danger of frost in the bucket

The Korean fir family offers many dwarf forms with a dense, beautifully shaped crown. They can take root in the garden, but are also often used as tub plants. Although the coniferous tree is hardy, the roots can freeze more easily in a bucket. They need protection or have to hibernate frost-free.
