Thus, the propagation of a blue spruce with seedlings succeeds
The multiplication of a blue spruce is only successful if a series of complex factors harmoniously intermesh. So that a seedling transforms into a magnificent spruce, it depends on the age of the mother plant as well as on the cutting time, the composition of the substrate and the growing conditions. Explore all relevant details here.
This is the ideal mother tree
In years of research, the Federal Forest Research Center in Vienna found out that the age of the mother tree has a significant influence on the successful course of vegetative propagation with seedlings. According to these findings, choose a blue spruce aged between 10 and 25 years.
Seedlings cut at the right time - That's how it works
In order for the rooting of a seedling to progress rapidly, the timing of the cut plays an important role. That is how it goes:
Branch tips from the shadow crown area as well as terminal drives are not suitable for cutting.
Thus, the success rate of 80 percent is not a dream
If mother tree and cuttings cut meet the requirements, the composition of the seed substrate makes a further contribution to the successful propagation. The experts at the Austrian Federal Research Center are in favor of a mix of perlite and polystyrene beads or gravel sand in a grain size of 4-8 mm. How to breed:
In the humid and warm microclimate, growth is progressing rapidly. Under ideal conditions, the seedlings have well rooted their pot until July / August, so they can be planted in the field. Only from this point in time does a regular supply of nutrients begin at a low level.
Tips
As a Christmas tree, the blue spruce tops the noble Nordmann fir primarily in terms of the lower purchase price. The same applies if you plan a picea pungens as an evergreen privacy hedge. Thanks to the uncomplicated propagation with seedlings, coupled with a rapid increase of 30 to 40 cm per year, the spruce trumps in this point the sedate Abies nordmanniana.
