Pine is a very common coniferous crop, which is considered undemanding to care and can serve as a decoration for city parks or ordinary summer cottages. Every gardener can grow pine, but it is important to adhere to the rules of care. It depends on how long the pine tree actually grows. Also, the pace of development is determined by the crop variety.
Growth in different periods
Pines perfectly complement any summer cottage. In order for the plant to grow and develop normally, you need to purchase a seedling from a special nursery.Digging up a tree in the forest is strictly prohibited.
Pine grows quite quickly. However, during the first 4 years the tree stretches only to 10-50 centimeters. Subsequently, the growth reaches 40 centimeters. Specific parameters depend on climatic conditions, variety and compliance with agricultural technology rules.
Many trees have been actively developing for 300 years. However, this is not the final indicator. Specimens dating back 5,000 years have been recorded. The annual growth varies depending on the age of the tree.
First five years
Within 5 years after planting, the crop must be systematically watered. Sufficient coverage of young crops is of no small importance. Thanks to this, they will be able to get stronger. Young trees have weak roots. Therefore, they cannot be touched for 2 years, since they do not take root well on the street.
Such plants are quite far from maturity, since they need to be finally replanted at 4 years. It is permissible to do this a little earlier or a little later. It is important that the pine reaches a height of 50 centimeters. After this, the crop will grow quite quickly, gaining 30-40 centimeters per year.
Subsequent years
Some trees are characterized by rapid development. That’s why pine trees grow to gigantic sizes after only 20 years. When choosing a crop for the garden, it is important to focus on growth rates. To decorate a small area, it is recommended to buy dwarf varieties.By the age of 10, the plants will add 50 centimeters annually. Some varieties are capable of increasing by 1 meter per year.
The pine tree develops much more slowly after it begins to bear fruit. At the age of 30-50, this crop begins to grow in breadth. At this stage, the tree acquires a thick and spreading crown.
Growth characteristics for different species
The speed of cultural development is determined by the influence of many factors. This parameter directly depends on the type of pine.
Scots pine
This is a fairly common plant that is often found in coniferous and mixed forests. In the nineteenth century, the plant began to be used in landscape design. For 1 year this tree grows by 10 centimeters. By the age of 5, Scots pine develops much more intensively. Its size increases by 30-40 centimeters per year, and after 10 years the growth of the crop is 1 meter.
By the age of 30, cultural development slows down. In this case, the bulk of resources are spent on increasing the diameter of the trunk. On the Baltic coast, specimens up to 50 meters high develop. However, their average length is 20-30 meters.
The listed indicators are considered average. Breeders also bred dwarf plants, which by the age of 10 do not exceed 2 meters in height. The place where culture grows is also of great importance. Plants do not develop well in poor soil, low temperatures, lack of lighting and strong winds.
Mountain
Mountain pine is somewhat different from ordinary pine. It is a shrub or small tree that has dense dense needles and gray-brown bark. The cones on the plant mature within 3 years.Moreover, their size can reach 2-8 centimeters, and their circumference – 1.2-2.
Mountain pine is a slow-growing conifer that can easily withstand dry weather and frost. The culture also develops well in shady places. In 1 year the plant grows by 15 centimeters. In this case, an adult tree can have a height of 4-6 meters - it all depends on the variety and growing conditions.
Black
This crop is a fairly large tree that requires a lot of light and is frost-resistant. Also, the plant can develop in urban conditions, since it does not require specific care. By the age of 8, the crop can reach 5 meters, and by the age of 25 - 10 or even more.
Black pine is used as a tapeworm. It is also planted in containers and used to decorate entrance areas. This evergreen conifer can grow up to 24 meters. However, the average height of the plant is 15 meters. An adult pine tree has a crown measuring 8-15 meters. Young plants develop rather slowly. Their annual growth averages 20-40 centimeters.
Kedrovaya
This culture is found in central Russia. It can also be seen in Mongolia, China, and Japan. Cedar pine also grows in North America, Japan and northern Eurasia. The height of the crop can reach 30-35 meters. However, sometimes there are giant crops that reach 40 meters or more.
Cedar pine lives 300-550 years, but some plants are more than 850 years old. Until the age of 20, culture develops rather slowly. But subsequently it increases by 30-40 centimeters. To enhance the development of cedar, favorable conditions must be created during the first 7-9 years of its life.
When pine develops under natural conditions, the first seeds appear only after 25-30 years. In other cases, this happens after 50 years. The rate of crop growth does not depend on climatic factors, but on the amount of valuable substances in the soil and the volume of moisture.
How to speed up or slow down growth
To speed up the development of pine, it needs to be fed properly. In this case, it is worth using the following means:
- Compost - when choosing it, you need to focus on the composition. It must contain at least 10 ingredients. Experts advise using liquid substances, as they are absorbed much better.
- Growth stimulants - excellent options include drugs such as Zircon and Epin. They activate the growth processes of the tree, but can also provoke its depletion. Therefore, such products should be combined with the application of mineral fertilizers.
- “Conifer growth activator” - this drug helps make the crop more resilient and develop certain microbiota. The product is sold in both granules and liquid form.
Sometimes gardeners have the opposite problem when the pine tree develops too quickly. In this case, the tree may not have enough space on the site. To limit its growth, it is necessary to adjust the length of the central shoot.
To stop the growth of the crop, pinch the shoot located on top. This procedure is carried out on trees that already have 3 layers of branches. However, it is best to wait at least 4 years. This manipulation can be carried out in spring or autumn.
The development of pine has a number of characteristic features. This culture can develop in different ways. This process is influenced by its variety and growing conditions.
