Increased growth in this country
the Nordmann fir originally comes from the Caucasus and the region around the Black Sea. Even if she has now also made her home here, the new living conditions are a little different. The tree doesn't necessarily need one Topiary. However, it has been shown that the Nordmann fir tends to have a stronger peak growth in local soils. The owners usually do not like this.

Slow down the fast-growing tip
The shoot that is responsible for the increase in height is called the terminal shoot. In order to curb its strong growth, it is not cut back, but rather inhibited in its growth potential in good time at the beginning of the vegetation period. To do this, the flow of juice is interrupted. Special scissors are available in stores. Pliers available that cut the tip in several places, but not cut all the way through.
- depending on the beginning of vegetation in May or June
- cut in the lignified part of the tip
- just below the new shoot
This measure is intended to ensure that the annual growth turns out to be about 30% weaker. In order to permanently regulate the development of the tip, this measure should be repeated every year if possible.
Tips
If you don't want overgrowth, this is what you should go for Fertilize waive. An occasional dose of Epsom salt is enough brown needles be prevented.
Cut the large shoot tip
If a Nordmann fir has become too big for its location or casts an undesirably large amount of shade, it can be because of its deep depths Root system badly excavated and transplanted will.
If felling seems to be the only option, then capping the tip can be risked, although the success of the measure is controversial among experts. After the cut has been made at the desired height, two strong guide branches should be bent upwards and tied. After 1-2 years, the weaker branch is removed while the other forms the new tip.
Note:
Inquire beforehand at the Environment Agency whether shortening a large, old fir is allowed or not. obtain appropriate approval if necessary.
