Abies Koreana is a slow-growing, medium-sized conifer originating from Korea; the adult specimens can reach 9-10 meters in height, over a few tens of years. This type of tree has an erect, pyramidal habit, with branches perpendicular to the stem; the reddish and smooth bark of the young specimens, with the time becomes greyish, deeply fissured. The leaves are needle-like, a few centimeters long, generally they grow grouped; they are dark green in the upper part, white-blue in the lower part. The oval pine cones, 7-8 cm long, are white-blue in color, darken as the days go by, until they become violet in color, often stained by the whitish resin. The winged seeds are dark, purple-purple.
With regard to the best exposure for the Abies Koreana it is advisable to place it in a luminous place, even in full sun; these trees withstand very harsh temperatures, and also develop well even in places with torrid summers. When planting a korean abies It is good to remember that it develops a very deep and conspicuous root system, therefore it needs an area with adequate amounts of soil.
It can withstand temperatures up to -25 ° C and can therefore be grown even in areas with very cold winters.
The young specimens must be watered regularly at the time of the plant, given their greater fragility; generally these trees are satisfied with the rains. It is good to avoid leaving the soil very wet near the plant.
Check that the soil offers proper drainage, so as to avoid possible water stagnation that could harm the plant.
The specimens of this variety develop without problems in any soil, preferring rich, deep and very well drained soils. The firs generally prefer to be placed in a ventilated place, with a good amount of land available, we do not recommend the cultivation in pots of the already large specimens; for this type of cultivation there are dwarf hybrids, which remain below the height meter.
Keep in mind that this type of plant has a root system that develops in depth, so to settle in an adequate space for future growth.
The multiplication of the abies koreana specimens generally occurs by seed, in spring; the young seedlings have a very delicate root system, it is good to grow them in pots for some years before planting them.
Once the new trees have acquired the necessary strength, they can be permanently planted and, despite being slow growing, they develop easily.
Abies Koreana: Pests and diseases
Sometimes this kind of tree can be hit by a processionary or by the aphid of the cedar.
If there are signs of an attack by these parasites it is good to intervene promptly using broad-spectrum pesticides, or, if natural methods are preferred, it is possible to resort to an infusion obtained with water in which garlic should be boiled . The filtered liquid can then be vaporized on the plant, to counteract the spread of the disease.
