Abies Koreana

What is the plant

It is a small to medium-sized evergreen coniferous tree growing to 10–18 m (33–59 ft) tall with a trunk diameter of up to 0.7 m (2 ft 4 in), smaller and sometimes shrubby at the tree line. The bark is smooth with resin blisters and grey-brown in colour. The leaves are needle-like, flattened, 1–2 centimetres (0.4–0.8 in) long and 2–2.5 millimetres (0.08–0.10 in) wide by 0.5 mm (0.02 in) thick, glossy dark green above, and with two broad, vividly white bands of stomata below, and slightly notched at the tip. The leaf arrangement is spiral on the shoot, but with each leaf variably twisted at the base so they lie mostly either side of and above the shoot, with fewer below the shoot. The shoots are green-grey at first, maturing pinkish-grey, with scattered fine pubescence. The cones are 4–7 cm (1.6–2.8 in) long and 1.5–2 cm (0.6–0.8 in) broad, dark purple-blue before maturity; the scale bracts are long, green or yellow, and emerge between the scales in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 5–6 months after pollination.

How to Care for the Plant

Water
These trees prefer consistent moisture in the soil, but they struggle in soil that remains too wet and soggy. So water your tree whenever the soil begins to dry out, but make sure no water is pooling around the tree.
Pruning
Korean fir trees don’t require much in the way of pruning. They typically form a symmetrical pyramid shape all on their own. However, you should prune off any dead, diseased, or broken branches as you spot them.
Fertilizer
Feed young Korean fir trees annually in the early spring before new growth picks up with an organic granular fertilizer. Mature trees can be fed at half strength unless you have poor soil.

Sunlight
This tree grows well in full sun, meaning at least six hours of direct sunlight on most days. But it also will tolerate partial shade.
Soil
Korean fir trees prefer a rich soil with good drainage. They also like an acidic soil pH. They can tolerate a neutral pH but won’t grow well in alkaline soil. They also don’t do well in clay soil.
Temperature
Korean firs tolerate heat and humidity better than many other fir trees. But they still prefer a cool, temperate climate. They also can handle some wind but should be sheltered from strong winds that can be extremely drying.
