Features of the Korea fir
As a fir, it is an evergreen tree, forming a conical crown, below with horizontally protruding branches. It can grow up to ten meters high, but there are also specimens that reach almost twice the height. The size of the Korea fir is given as around 3-5 meters. However, it grows very slowly and in the year only about 10-15 cm. The individual needles of the trees are between 1-2.5 cm long and are dull. They form around the whole branch and give it a round, full appearance. They are glossy dark green on the top and white stripes from below to make the tree look white from below.
The bark of the Korea fir is colored dark olive to black and looks speckled. The branches have a pale brown bark, which can be slightly hairy. The tips of the Korean fir are from initially slightly brown to see white later.
The fir tree is also monoecious as a fir tree and has both female and male cones on its branches. The male cones are found on the branches between the pine needles and in the treetop. They are only 4-5 mm in size and round, after opening they are 1 cm long and yellow. The female cones sit on top of the branches, are 2-5 cm long and elongated. As young cones, they are yellow-green, light pink or slightly dark red. The cones of the Korean fir are already formed in young trees from 1 meter in size.
Tip: The seeds from the cones are needed for propagation.
Location for korea fires
In their homeland, the Korean fir is in mountainous heights. There she grows in sunny places, she feels well even in bright shade. The location is mostly humid and cool in this region. She likes it sheltered from the wind and wants to stand in a nutrient-rich soil. Although it is not sensitive to frost, it is sensitive to sudden and unusual frost fractures.
A Korean fir is mainly planted because of its cones, which stand upright on the branches and give a very nice picture. Because the Korean fir grows slowly, it is often placed in native gardens. But it is also very popular because of its decorative appearance, especially the bright undersides of the needles stand out. In addition to planting in the garden, it is also used for the decoration of tombs, also here, their slow growth is well received. Of course, the increasingly popular Japanese gardens are the ideal visual space for a Korean fir. The soil at the location of the fir should be slightly acidic and humus. It can also tolerate a slight amount of lime in the soil, but it does not like clay soil or compacted soil at all. Such earth should be loosened up with sand, also clay is a good addition. If the soil is always moist and fresh, the Korean fir will grow slowly but steadily.
Pour and fertilize
Of course, because of their preference for damp soil, the garden owner should make sure that the soil does not dry out in the summer. Even more so than in summer, the Korean fir must be cast in the fall, the area under the tree should be covered with a thick layer of mulch. This keeps the moisture in the soil and also ensures the typical forest climate that gets the fir very well. If manure is to be fertilized, it is particularly suitable for pine fertilizer, which contains nutrients specially adapted to this type of plant.
Tip: A Korea fir is not cut back, it is not necessary and would only destroy its overall appearance.
