Jacobsen pine is a very attractive crop that is often used in landscape design. It is a mountain dwarf plant that is similar in appearance to bonsai. This culture was developed in Denmark in the nineties of the last century. Today it is often used to design rocky gardens and planting in containers. For a tree to look decorative, it needs to be properly cared for.
What kind of variety is this
According to the botanical description, the Jacobsen variety is an evergreen dwarf plant that has all the properties of a bonsai. The culture is characterized by curved shoots with dark green needles. The branches themselves are quite thick and strong.They are characterized by a horizontal growth direction, and in winter they are covered with white buds.
As the culture develops, its base becomes exposed and becomes bonsai-like. This form is especially appreciated by fans of decorative conifers. The shrub is distinguished by its rather slow development. In 1 year it increases by a maximum of 4 centimeters. Thus, at 10 years its height does not exceed 50 centimeters, and the diameter of the crown is 90.
The plant has strong immunity. However, if the rules of agricultural technology are violated, it may suffer from the development of pathologies and pest attacks. To avoid problems, it is worth using fungicides and insecticides.
Landing nuances
In order for mountain Jacobsen pine to develop normally, it is important to carry out planting work correctly. To do this, it is recommended to give preference to an open and well-lit area. Lack of light causes the needles to turn pale and the shoots to stretch.
To plant a plant, it is recommended to do the following:
- Make a hole 2-3 weeks before planting. This will allow the soil to settle and become evenly moistened. The size of the hole depends on the size of the seedling's roots and the type of soil.
- Place drainage at the bottom of the hole. For this you can use expanded clay, crushed brick or crushed stone. Then you need to place coarse sand or gravel. The thickness of the drainage layer should be 20 centimeters.
- Mix the top layer of soil with leaf soil in equal parts. Then add a fifth of sand to the composition.You can also use manure, complex nitrogen fertilizer, compost - approximately 50 grams.
- Pour the substrate into the planting hole and place the seedling on the formed mound. In this case, the root collar should be located at the same level with the surface of the earth.
- Water the soil generously and cover it with a layer of mulch. For this, it is permissible to use peat or pine needles.
How to care for a tree
Jacobsen pine is considered low maintenance. However, violating the rules of agricultural technology entails negative consequences. When growing a plant in open soil, it needs to be watered, fed, and mulched in a timely manner. It is also worth pruning regularly. Pine of this variety can be grown in the usual way or on a trunk.
The culture is considered undemanding to soil moisture. Therefore, it needs rare watering during the summer drought. To increase the plant's resistance to frost and aggressive sunlight, water-recharging irrigation is carried out in late autumn and early spring.
It is enough to apply fertilizer once a year. This should be done before the active growing season begins. As a top dressing, it is permissible to use universal combined compositions for conifers. In this case, the solution must be prepared strictly according to the instructions.
To reduce the need for watering and weeding, it is necessary to mulch the tree trunk circle. For this purpose, you can use pine chips, pine needles or peat. To make the crown thicker, it is recommended to periodically pinch it. Jacobsen pine tolerates crown formation very well. This makes the variety more valuable from the point of view of use in landscape design.
Young seedlings need to be insulated for the winter. For this purpose, burlap or spruce branches are used.Since the crop is compact in size, its insulation does not cause any particular difficulties.
Application
The plant is often used to decorate alpine slides, rockeries, and heather gardens. This culture can be used as a tapeworm. It is also perfect for forming group compositions.
Jacobsen pine is a fairly common crop that is often used to decorate garden plots. In order for the plant to always remain decorative, it needs to be properly cared for. In this case, the crop needs to be watered, fertilized, and pruned. Young seedlings must be insulated before the onset of cold weather.
