A lightly placed and well cared for Nordmann fir develops magnificently. So every summer she says goodbye a little higher than she greeted him. However, many years will pass before the tree has developed its full potential. These growth steps are possible.

A Nordmann fir grows up to 30cm per year

Growth rate depends on age

When young, the Nordmann fir must first grow well and form new masses of needles. It therefore only grows slowly in the first four to five years. After that, the growth rate increases steadily. If the tree has unfolded its full height potential, there is inevitably no longer any noticeable increase in height.

tips

The weak growth at the beginning of its life makes it possible for the fir to first be cultivated in a bucket and only planted out 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 grey-yellow color of the freshly expelled needles. These shoots are sensitive to frost.

Pay attention to the planting distance

Under the roots of a Nordmann fir there is also a long and deep taproot. The longer the tree grows in one place, the harder it is to dig up and transplant without damaging the roots. Therefore, when planting, keep a planting distance of at least 1.5 m to other firs. There may even be a little more to buildings.

Stopping growth due to lack of space

Limiting the natural growth can be attempted by pruning measures. Since the tree does not tolerate pruning very well and does not sprout again from old wood, it is only suitable for topiary to a limited extent. The tip can also be cut off. However, get more information on this so that you can then restore the typical pyramidal crown shape.

Other ways to limit growth:

  • stop fertilizing
  • with the exception of Epsom salt for needle tanning
  • careful cutting of the taproot
