The rate of growth is age-dependent
At a young age, the Nordmann fir must first grow well and form new needle mass. It therefore only grows slowly in the first four to five years. After that, the growth rate increases steadily. Once the tree has developed its full height potential, there is inevitably no more remarkable height growth to be recorded.

Tips
The weak growth at the beginning of their life makes it possible that the fir tree is first cultivated in a tub and only planted years later.
Average growth values
The following values were determined for the average growth of the Nordmann fir:
- annual growth in height: 25 to 30 cm
- annual growth in width: about 15 cm
- maximum height: around 25 m
- maximum width: up to 8 m
- after 10 years a Nordmann fir is about 2 m high
Color of the new shoots
The annual new growth can be easily observed on the conifer. This is made possible by the yellow to gray-yellow color of the freshly driven needles. These shoots are sensitive to frost.
Pay attention to the planting distance
Under the root a Nordmann fir also has a long tap root that extends deep into the earth. The longer the tree grows in one place, the more difficult it is to dig it up without damaging the roots transplant. So keep one when you are planting Plant spacing from min. 1.5 m to other fir trees. It can even be a little more for buildings.
Stop growth due to lack of space
Limiting natural growth can be attempted by cutting measures. Since the tree is not very pruning and does not sprout from old wood, it is suitable for Shape cuts limited. That too Cutting off the tip is possible. Obtain further information on this so that you can then restore the typical pyramidal crown shape.
Other ways of limiting growth:
- the Fertilize to adjust
- with the exception of Epsom salts against Needle tan
- careful cutting of the taproot
