Western thuja Globosa (Globosa) - a very beautiful small bush with spherical crown. It is very popular all over the world. It is a key ornamental shrub in landscape design.
Thuja Globosa (Globosa): description
The compact coniferous bush of the thuja Globosa appeared in the middle and northern latitudes of East Asia. Belongs to the Cypress family. A dwarf bush grows no more than one meter in height. The spherical thuja is quite resistant to frost and disease, so growing it is not difficult.
The description of Globose and other species of thuja is not very different. A small neat dense tree has the shape of a ball. On its small coniferous branches are dense green scales.
Western Globose Thuja
In winter, the color of the scales acquires a brownish tint. The thuja has a very dense crown; this effect is created due to the intersecting branches. On the surface of the branches there are small cones, the size of which does not exceed 1 centimeter.
The bush grows very slowly, each year it grows by only 4-7 centimeters. As a result, a shrub that is about 20 years old grows no higher than 1.5 meters.
It is interesting! Thuja Globosa is one of the most long-lived shrubs on earth. Small trees are known that are 200 years old.

Planting and caring for thuja globosa
Thuja spherical Globose is a very unpretentious and easy-to-care plant. If you provide him with all the necessary conditions, it will grow well with minimal attention. The plant is cold-resistant, so planting and care in the middle and northern latitudes is quite possible.
How to plant thuja globosa
The best time for planting the western Globosa thuja is spring or autumn. The landing site must be chosen with good soil moisture. It is not recommended to choose completely open areas, let them be with partial shade. It is better to avoid open areas on the north side, cold piercing drafts adversely affect the plant. It grows well on fertile and loose soils.
Before planting seedlings in the ground, it is necessary to clear the area, if necessary, you can dig it. The depth of the hole depends on the size of the earthen coma enveloping the root system of the seedling. If a drainage layer is covered at the bottom of the pit, then it needs to be dug deeper by 10-20 centimeters.
View of bushes on open ground
Each seedling must be well checked for damage or infection. The roots of a healthy thuja should be white. Each seedling is placed in a separate hole and sprinkled with a mixture of fertile land, river sand, peat and humus. It is not necessary to deepen the bush much into the ground - the boundary of the beginning of the roots should be at the level of the upper layer of the earth.
Note! If the seedlings were bought in special stores, then you can not make fertilizers. Such seedlings are already treated with a special useful solution.
Watering mode
Watering should be regular, but moderate. It is enough to water the bush twice a week. It is useful to loosen the soil after each watering in order to prevent moisture stagnation. High humidity leads to the formation of fungal diseases and mold, which has a detrimental effect on the coniferous plant.
In addition to watering, it is necessary to spray the ground part of the bush. Sprinkling should be carried out less often and not as abundantly as watering so that the plant does not get sick.
Important! Do not water thawed with cold running water. Irrigation water should be settled and room temperature.
Top dressing
To form a lush crown, thuja must be regularly fed with mineral and organic fertilizers. Feeding is especially necessary in the early years of active growth. Young seedlings, unlike adult bushes, are not able to extract from the soil all the nutrients necessary for growth.
The first top dressing is carried out when planting a seedling. This top dressing is the most important of all subsequent ones; it must be complete and include minerals along with organic ones. The role of organics can be stale manure, rotted humus or compost. At the bottom of the pit for planting, in addition to organic matter, nitrogen and phosphorus fertilizers are introduced.
Further feeding is carried out every spring and autumn, during the first 3-5 years. In spring, the composition of the top dressing should include the following elements:
- phosphorus;
- calcium;
- nitrogen;
- magnesium;
- manganese;
- potassium;
- iron;
- zinc.
Top dressing is carried out with superphosphate, ammonium nitrate, potash fertilizers and other means. However, it is more efficient to purchase complex preparations specifically for thuja or plants of the cypress family, which are sold in specialized stores.
In autumn, coniferous thuja is fed with Fitosporin. As soon as the thuja Globosa picks up growth and strengthens top dressing, spend once a year - in the spring.
Important! It is impossible to excessively fertilize thawed with mineral fertilizers - their excess is harmful to the growth of the bush. Nitrogen-containing preparations are introduced until March, not later.
Features of summer care
In the summer, the thuja western Globosa requires the following types of care:
- mulching;
- pruning of shoots to form a crown;
- regular watering;
- loosening the soil.
Otherwise, in the summer the thuja does not require special attention.
Preparing thuja globosa for winter
Shrub needs preparation for the winter. First, spruce branches lay around the trunk in the basal zone. This procedure warms the roots and prevents pests, especially rodents.
The crown is trimmed, all dried up and rotted, as well as extra shoots are removed. In order that the snowdrifts could not damage the ground part of the shrub, it is necessary to build a special frame around it. On top of this structure or from below it melt is covered with a protective material: agrofibre or polyethylene.

Thuja Globosa breeding
Thuja spherical Globose well takes root when propagated by its cuttings. It is this method that is most in demand among experienced gardeners and beginners. In addition to propagation by cuttings, thuja can be propagated by the vegetative method and with the help of seeds.
Note! Propagate by seeds for a very long time, but the bushes grow more hardy than with other methods.
Propagation by cuttings
With the help of cuttings you can get as many bushes as you want. The procedure is best done in the fall, so that they have time to give the roots and not dry. Before cutting the cuttings, it is necessary to prepare a room where they will take root. A construction in the form of a small greenhouse is well suited for this. In advance, in the greenhouse you need to prepare the necessary humidity - at least 70%.
Strong, large shoots that are at least 3 years old are selected; the base of this shoot must necessarily have the so-called “heel” - a small part of old wood. Cuttings are cut near this "heel", all needles on the bottom of the cuttings are removed.
Cuttings are planted in the finished substrate, which before that were kept for several hours in water. Cuttings are deepened into the soil to the border where the growth of needles begins. The coniferous part should not touch the ground so that the cuttings do not rot.
If the cuttings begin to appear young shoots, then the development of the root system has begun. Now you can periodically ventilate the cuttings, thus gradually hardening the seedlings. After some time, the seedlings are taken out daily for a short time. It is at this time that watering begins, so the seedlings will be the most seasoned before planting them in open ground.
Note! During the growth of cuttings in the greenhouse, you do not need to spray and water them.
Why does thuja globosa turn yellow
The resistance of thuja Globosa to diseases is very high, but sometimes it starts to hurt. First of all, harmful environmental influences affect the condition of the ground part of the shrub. The reason for the appearance of such signs is adverse climatic conditions and / or improper care.
Some gardeners are faced with the problem of yellowing and browning of the thuja crown. This happens most often in the spring. Changes in foliage of bushes can occur due to improper shelter for the winter.
Yellowed needles of a plant
Some materials for shelter can create a greenhouse effect inside and worsen the condition of the bush. They let in ultraviolet rays, the temperature inside heats up, because of the dense material there is no air ventilation. If the problem of yellowing is associated with improper shelter for the winter, in spring thawed Globosa is watered with biostimulants so that the plant begins to actively develop.
A problem may occur in the summer, the reason lies in the stagnation of moisture in the soil. Most likely the plant was abundantly watered or groundwater passed nearby. In addition to yellowing of coniferous scales, mold and fungus may appear in the basal zone. To avoid this problem, it is necessary to loosen the earth after each watering. The base of the trunk must be treated with an antifungal drug, and cut off the damaged branches with secateurs.
Important! If the plant grows near groundwater. It is necessary to transplant it. No treatment in this case will have a result.
Decorative western thuja, thanks to its spherical dense crown, will decorate any garden. With the help of cropping, you can create any shapes of your choice. Many plant a prickly compact spruce Glauka and thawed Globosa nearby - the plants are similar in shape and, when alternated, create an amazing composition.
