Conifers are quite popular when decorating garden plots, adjoining territories, parks and squares. This will determine both the number of plants and the place of their planting on the site.
Otherwise, it may turn out that the growing tree will block the sunlight and become an obstacle in the passage. Taking into account the fact that together with such plants as thuja, junipers, firs, pines are also becoming in demand, it is important to know how much pine grows, what size an adult tree can reach.

Pine, short description
Like most conifers, pines refer to evergreens with branches on which needles are located, collected in a bunch of 2, 3 or 5 pieces. It is by the number of needles in the bunch and the color of the needles that one can distinguish one type of pine from another. Depending on the number of needles, pines are classified as two - three - five-coniferous. The life forms of plants from the Pine genus, the Pine family are:
Pines are widespread almost everywhere. In geographic areas with a tropical climate, they grow mainly in mountainous areas. In areas with a temperate and even cold and subarctic climate, pines form whole pine forests or are part of mixed forests. Representatives of the Pine family in South America are not found in natural forests. On one plant, pine trees have both male strobila (cones), collected by an ear, located at the ends of young branches, and female strobila in the form of oval cones in the upper part of the plant.
In total, there are more than 100 species of pines on the globe, about 16 wild pine species and about 70 imported ones grow in natural conditions on the territory of Russia. The most common:
- Scots pine, up to 40 meters in height
- Korean pine or Korean cedar, up to 50 m
- dwarf cedar, up to 1 m
- Crimean pine, on average up to 30 m
- Weymouth pine, up to 50 m
When working with wild pines, breeders have obtained many slow-growing miniature and dwarf pines. These varieties, as a rule, differ in the minimum annual increments.
How a pine tree grows from germination to five years
When choosing a type of pine for a garden, many amateurs most often choose low varieties. Sometimes when buying it is difficult to say whether a specimen will grow to one or two meters or easily overcome all 20. The rate of annual growth is an important distinguishing feature of many pines, both wild and ornamental. In general, pines are fast-growing plants, however, the growth rates of this plant vary throughout life.
In the first four years, the pine seedling grows by no more than 10 cm per year. And at the age of four it does not exceed 40-50 cm in height.
In the first year, pine seedlings do not grow more than 5-6 cm.But if you follow simple recommendations, then young pines will be 9-10 cm each.It should be borne in mind that pine has great needs for light, it is desirable that neither weeds nor other plants create shade for seedlings. An important condition is the organization of watering. The roots in the first two years of pines are rather underdeveloped. To ensure not only the availability of water, but also of minerals, the plant needs regular watering. In the first weeks after germination, the pine is watered daily, choosing for this morning or evening hours.

To get a faster growth, in the third year, after the pine seedlings have sprung up, they need to be planted and grown in schools for another two years. The transplant will give an impetus to the formation of the root system, which will ensure more rapid growth of the ground part of the pine in the future. Here it is important to plant pines at a distance of at least 20 - 25 cm from each other. With the correct cultivation of pines in schools, they will increase by about 15 cm in the first year, but they will still not be ready for planting in a permanent place. And only two years later, at the age of four, pine seedlings will reach a size of 40 - 50 cm and will be ready for transplantation to a permanent place.
If growth has slowed down due to inadequate care, then it is better to replant the pine next year, when it will be already five years old. It should be remembered that miniature varieties give a slightly smaller annual growth and the older such a pine, the slower it grows. In addition, for various reasons, the growth of seedlings of one year can differ significantly. The maximum growth of a pine tree can reach 70 -90 cm by the age of five.
How pine grows from 5 to 50 years
Most pines, such as Scots pine, Weymouth pine, are fast growing trees. At the age of five to ten years, they give an increase of 25 to 60 cm annually, and over ten years, the growth of most pines reaches from 0.6 to 1 m annually. In pines aged 30 - 50 years, the growth in height slows down and the growth of trunks in width begins.
Most of the pines are long-lived and live on average 150 - 300 years. Miniature and dwarf pines grow very slowly with age and their growth is from 2.5 cm to 10 cm annually.
Thus, when choosing a pine tree for a site, you need to take into account its growth rate and adult size. After all, many pines at the age of 15 - 20 years will turn into real giants with bare trunks and a rather modest decorative crown at the very top. For small areas, you should not take wild-growing forms, but it is better to dwell on miniature types of pine with a beautiful color of needles and an attractive crown shape. For cultivation on the site, you can recommend the types and forms of pines:
- cedar pine "Stricta", grows up to 1 m, needles with a blue tint, the shape of the crown is conich
- mountain pine "Gnome", up to 2 m with a pyramidal green crown
- Weymouth pine "Radiata", up to 1.5 m, with gray - blue needles
- Weymouth pine "Aurea" up to 8 m, needles of golden yellow shade
- Weymouth pine "Minima", up to 0.5 m, spherical crown, light green needles
It is important to remember that it is better to purchase decorative pines in proven nurseries, then a miniature pine will meet expectations and will not turn into a huge giant.
