Like any other type of fir, the Nordmann fir needs a tip. Without them, the typical pyramidal crown shape would no longer exist. Nevertheless, she sometimes has to use the scissors to shorten the said tip. We clarify when and why this can be useful.
The tip sometimes shoots up a little faster than desired
Increased growth in this country
The Nordmann fir originally comes from the Caucasus and the region around the Black Sea. Even if she has meanwhile also made her home here, the new living conditions are a little different. The tree does not necessarily need a topiary. However, it has been shown that the Nordmann fir tends to grow more strongly in local soils. The owners usually don't like it.
Slow down the fast-growing spike
The shoot responsible for height growth is called the terminal shoot. In order to curb its strong growth, it is not cut back, but its growth potential is inhibited in good time at the beginning of the vegetation period. To do this, the flow of juice is interrupted. Special scissors or pliers are commercially available, with which the tip is cut in several places, but not completely severed.
- depending on the start of vegetation in May or June
- cut in the woody part of the tip
- just below the new shoot
This measure should cause annual growth to be around 30% weaker. In order to permanently regulate the development of the tip, this measure should be repeated every year if possible.
tips
If you do not want too much growth, then you should refrain from fertilizing. An occasional dose of Epsom salt is enough to prevent brown needles.
Cut off large shoot tips
If a Nordmann fir has grown too large for its location or casts an undesired amount of shade, it is difficult to dig up and transplant because of its deep root system.
If felling seems to be the only option, cutting the tip can be attempted, although the success of the measure is disputed among experts. After the cut has been made at the desired height, two strong leading branches should be bent up and tied. After 1-2 years, the weaker branch is removed while the other forms the new tip.
Notice:
Before doing so, find out from the environmental agency whether it is even permitted to shorten a large, old fir tree or, if necessary, obtain a permit.
