Methods of reproduction and use of Pseudotsuga menziesii ssp menziesii 38

Green Douglas fir is a relatively large tree even if grown in a yard or garden bounded by a landscape grass limiter. It reaches a height of 120 m, and the thickness of the trunk reaches about 5 m. It is rarely produced in Bulgaria due to the lack of organic seeds from plants and vegetables.

The crown of the Green Douglas ландшафтен ограничител за трева is regular and resembles a cone in shape, with horizontally oriented branches (this can be seen from the photo taken by daryl_mitchell).

The bark is gray-black with deep cracking due to the growth and aging of the tree. At a young age, the branches of the Douglas fir are not hairy and yellow-green in color, later they acquire a gray-black color.

The buds resemble the shape of an egg, are slightly pointed at the top and are dark red in color. The leaves are flat with a linear shape and are 2-3 cm long, dark green above and with two white stripes below.

Green Douglas Fir (Pseudotsuga menziesii ssp menziesii) On top are dull or almost dull. The leaves are arranged sequentially on the branches. They are oriented in two rows.

The male fringes are orange-yellow in color and are located in the axils of the leaves. Once ripe, the cones reach a length of 10 – 12 cm.

The cones are formed by about 50 seed scales and just as many coverings. The roof scales are three-part at the top, and the middle part is longer due to its strong draining.

The roof scales are longer than the seed scales, but they are attached to them and are directed towards the top of the cone (this is clearly seen from the photo taken by brewbooks).

Douglas fir is widespread in western North America, Canada and Mexico. The places where it grows are characterized by high soil and atmospheric humidity, small fluctuations in temperature and almost no sub-zero temperatures in winter.

Due to these ecological requirements, this species is rarely used by specialists in the field of landscaping in Bulgaria. The suitable areas for it are in the southernmost parts of our Black Sea coast, where the Mediterranean climate is felt, where the winter is milder.

Douglas fir (Pseudotsuga menziesii ssp menziesii) For its normal development Green Douglas fir requires rich, deep, fertile and light soils.

The retention of places that have low temperatures is not favorable for its development. Green Douglas fir does not tolerate calcareous soils and suffers when planted on such.

The consequences that occur in such cases are deterioration of its decorative effect, drying of some of the branches or the whole plant.

Does not tolerate air pollution. It is moderately light-loving, it can grow in both shade and sunny habitats. In our country it grows best in the beech-fir belt, where there is more moisture that she loves.

Before planting it in your yard, it is good to research whether the climate is suitable for it. Otherwise it is a suitable plant for landscaping.
