Thunberg’s barberry “Atropurpurea” has inedible fruits and a short flowering period, but is still loved by gardeners. The owners of the sites are attracted primarily by the unpretentiousness of the culture and the neat forms of growing shrubs.
Thunberg's barberry "Atropurpurea" is grown either for decorative purposes or to form a hedge. Although the fruits of this variety are forbidden to eat, their appearance is still involved in creating an aesthetic appearance. Description Berberis thunbergii Atropurpurea should start with the fact that the height of the bush is 2 meters and the width reaches about 3.5 meters. By the way, the red shade of the barberry leaf, changing from purple to bright red, explains its popular name - red barberry. If the culture is grown in the shade, then the decorative leaf is disturbed due to green stains.
Atropurpurea blooms in May and lasts 2-3 weeks. Rounded buds in an open form reach only one centimeter and form racemose inflorescences from 3-6 copies. The inside of the petals is bright yellow, and the outside is purple. The crown has a spherical shape due to the presence of a large number of thin lateral shoots. In a year, the plant grows by 20-30 centimeters, increasing not only in height but also in width. Oblong fruits are painted in bright coral color.
Thunberg barberry is able to exist from 50 to 60 years. It can be grown in any locality, including with cold winters. The main obstacle to the successful development of culture may be overdried or waterlogged soil.
How to plant?
When landing, you must follow a few basic rules.
- The location is determined so that the site is well lit throughout the day. Even short-term exposure to shadows leads to a change in the qualitative characteristics of the culture.
- Excess moisture can be extremely negative for Atropurpurea barberry, so it is important to avoid lowlands and areas with a high occurrence of groundwater.
- The distance between the plants should be sufficient, since barberry is prone to overgrowth. Naturally, in the case of the formation of a hedge, seedlings are grown closer.
- In the event that a spring planting is ahead, the soil should be prepared in the fall. If the crop lands in the autumn months, then preparation begins in about 4 weeks.
- It is important to avoid high acidity, so if this parameter is violated, lime or dolomite flour is added to the soil. Loam and chernozem are facilitated by using peat and sand.
- The size of the digged hole is determined depending on the age and size of the plant. When planting seedlings under two years old, width and depth equal to 25 and 30 centimeters will be sufficient. When a bush is transplanted older than three years, you will need to dig a hole, the diameter and depth of which are 50 centimeters.
- If the barberry of Thunberg Atropurpurea is to be part of a hedge, then it will be necessary to dig a trench, the width and depth of which will be 40 centimeters.
- While the hole is being created, the upper fertile soil layer will need to be mixed with a pair of buckets of sand, with a pair of compost buckets and 100 grams of superphosphate. The resulting pit is moistened, and then a seedling is placed in it.
- Each seedling should already have a well-developed root system, which is freed from dried and damaged pieces. It must be monitored to have four or more shoots covered with smooth red-yellow bark.
- It will be important to disinfect the shoots with fungicides, as well as stimulate the seedling in a special solution.
- The seedling in the hole is installed vertically, and its roots are necessarily straightened. Having fallen asleep with the soil mixture, it is necessary to make sure that the root neck rises at the level of 5 centimeters from the surface. However, if in the future the bush will undergo division, experts recommend deepening the root neck.
- Landing ends with irrigation and mulching of the trunk circle. If planting occurs in the spring, it is better to use organics as mulch, and if in the fall, then straw or dried leaves. All work is recommended to be carried out in the morning before sunrise or in the evening after sunset.
Atropurpurea barberry can be propagated by seed method, but the process will be dragged on for a long time. First, in autumn, seeds are extracted from the fruits, which for about 40 minutes are aged in a manganese solution. Having dried the material, it can immediately be sent to the garden. The next year, after the appearance of a pair of leaves in barberry, he will have to dive. Culture is transferred to a permanent habitat only in the third year of life.
Vegetative propagation occurs by cuttings, layering or division. Cuttings are cut in the last week of June and, having received treatment with growth stimulants, are seated in containers under a plastic or glass “roof”. A barberry will take about a year to form a reliable root system, after which it can be planted on a permanent site. Work with layering starts in early spring. Healthy annual shoots are fixed on the surface with brackets and sprinkled with earth. In this case, it is imperative to control that the crown rises above the ground. In the fall, Atropurpurea should already form roots.
The third way is to divide the bush, which is carried out in autumn. For the procedure, only those plants that have crossed the mark of five years of age and have a deep root neck are selected. The shrub is carefully scooped up and divided by either a sharp shovel or a knife into the required number of parts. The landing of the resulting delenok is carried out immediately.
How to care?
Atropurpurea Tunberg’s barberry care is made up of standard ingredients. Irrigating an adult shrub requires a couple of times a month, but it is still better to focus on the condition of the soil and in no case to allow drying out. Watering is necessary for young barberries more often - once or twice a week. "Atropurpurea" reacts negatively to the lack of oxygen in the soil, so you will have to periodically loosen the earth in the near-stem circle. You can not ignore such an important procedure as the removal of weeds.
Mulching is carried out using sawdust, peat and other common materials. The layer laid out after irrigation and weeding should be from 5 to 7 centimeters in height. Fertilizing is carried out according to a certain scheme. In spring, urea is used immediately after planting, and then every four years. The bush is irrigated with 30 grams of the substance, diluted in 10 liters of water. A bucket of learned solution usually leaves per square meter of landings.
The next top dressing is carried out before flowering and upon its completion. Usually a kilogram of rotted manure or humus is used, which is diluted with 3 liters of settled water and aged for three days. Further, having filtered the solution, it is necessary to dilute 1 liter with three liters of water. Shrub is watered with this top dressing. When leaf fall is over, barberry can also be fed. It will be enough to pour 15 grams of superphosphate and 10 grams of potassium sulfide under each shrub. If no rain is expected, then top dressing can be slightly irrigated to dissolve the substances.
An adult plant does not require any additional protection before winter frosts. If the barberry is young, then it is worth covering it with burlap. Thunberg barberry pruning is carried out in early spring, while the plant is still at rest. As a rule, a shrub is trimmed with a ball or a rectangle, necessary for the formation of a hedge. A sanitary haircut is carried out either at the beginning of spring or at the end of autumn, freeing the plant from frozen, dried or damaged branches.
Diseases and Pests
Atropurpurea barberry quite often contains pests, for example, aphids, sawflies or moths. Treatment with a soap solution prepared from 150 grams of laundry soap diluted in a five-liter bucket of water can help. Processing shrubs with a solution of chlorophos or another suitable insecticide will also help.
Of the diseases, gardeners most often encounter bacteriosis, spotting, rust, or powdery mildew. Damaged parts of the shrub are necessarily cut and burned, after which the plant is treated with Bordeaux liquid, colloidal sulfur or a copper-containing solution. As a preventive measure in spring, loosening of the trunk circle and cleaning of dried weeds must be carried out.
