Crown diameter of white deren
An adult white turf shrub can grow to a considerable size. Individual specimens can grow up to 5 m in diameter. Bushes often standing next to each other are intertwined, forming impenetrable thickets. This feature of the white dogwood is used by landscape designers when creating hedges.
The height of the white turf
Free-standing svidina bushes can grow up to 3 m in height. In decorative gardening and landscape design, their growth is often artificially limited by pruning the shoots at a height of 1.5-1.7 m and giving them a rounded shape.
How fast does white dogwood grow?
White dogwood is distinguished by its rapid growth of shoots. Over the course of a year, their length can increase by 0.5 m or more, depending on the care and weather conditions.
Derain white in landscape design
Derain white is a real find for novice landscape designers. This plant looks great in individual plantings and in groups, while it does not lose its decorative effect even in winter. Its crown can be formed without fear of the consequences, since the shrub tolerates pruning well.
Derain white in landscape design - in the photo below.
Derain white is widely used for landscaping streets, parks and squares, it is unpretentious and undemanding to care, it perfectly tolerates the vagaries of the weather and gas pollution in megacities. Often it is planted in the territories of health care institutions, hospitals and sanatoriums.
White turf hedge
Growing hedges is one of the main directions of using white turf in landscape design. This is due to the decorative properties of this shrub; it does not lose its attractiveness at any time of the year. Derain is unpretentious in care and undemanding to soil. It is easy to form and tolerates pruning very well. Hedges perfectly mask simple or nondescript fences, giving the area a more presentable look. They can also act as independent elements of a landscape gardening composition.
Growing a white turf hedge is pretty easy. For this, seedlings are planted in a row at a distance of 1-1.2 m from each other. After a year (for autumn planting - after a year and a half), all the bushes are cut to the same height - 15-20 cm from the ground. This is done in early spring, before the beginning of the growing season. With the help of this technique, the growth of lateral shoots is stimulated, the thickening of the bushes is artificially increased, the hedge is obtained more dense. When the bushes reach the age of 3 years, you can start forming the crown, cutting it in accordance with the selected type.
Derain white at a young age has rather flexible shoots, so it is often used to form arches and semi-arches, thus making paths and alleys. Initially, the branches are fixed with twine, giving them the desired direction. Over time, the shrub gets used to it and retains the necessary shape on its own.
What is the combination of white woodland
Derain is not an antagonist and goes well with almost all garden plants. It grows well next to other shrubs: barberry, spray roses, boxwood. For decorative purposes, it is often planted next to conifers.

Planting and leaving the white deren
White derain is an extremely unpretentious plant that does not require special care. It has no special requirements for soil composition, irrigation frequency or disease prevention. The homeland of this plant is Siberia, so the shrub is hardy, winter-hardy and picky.
Terms and rules for planting a white deren
For the most decorative look, it is better to choose open areas or light partial shade. This is not decisive for the development of the plant, although it gives it a great decorative effect. This shrub grows well on moist fertile soils, but this factor can be ignored. Any areas are suitable for planting: clay, rocky soil, sand - white turf will grow everywhere if a sufficient level of moisture is provided.
For planting, it is better to choose autumn or early spring. If a seedling has a clod of earth on its roots, this is almost a 100% guarantee that it will take root. At this time, planting pits are prepared about a third larger than the volume of the root system of the seedling. If the soil is poor, before planting, it is worth adding a small amount of complex mineral fertilizer or humus to the hole.
The landing procedure is not difficult. The seedling is placed vertically in the hole so that the root collar is at ground level. Then the root system is covered with earth, lightly tamped and watered abundantly in the root zone. If the planting was carried out in the spring, it is better to mulch the ground around the seedling with peat, this will help retain moisture.
Watering the white turf
As a rule, watering is not required for this shrub. If the planting site is chosen correctly, soil moisture and atmospheric precipitation will be quite enough. An exception can be made only during dry summer periods. At this time, you can water the bushes once a week at the rate of 1-2 buckets of water for each bush.
It is not necessary to feed the shrub. Some decorative species can be fed once a year, in spring, by introducing a complex mineral fertilizer into the root zone. Peat or humus will serve as additional feeding if you mulch the root zone with it.
When to cut white turf
This shrub grows quickly and chaotically, therefore, without pruning, it will very soon resemble a large, shapeless heap. Plants are cut several times per season. In the spring, they carry out a sanitary cut, removing dried or broken branches. The rest of the time, the selected crown shape is maintained, while the haircut is done every 3-4 weeks. The last time the bush is cut is usually in late July or early August.
The bright red stems of the plant serve as a decoration for the garden in winter. Therefore, rejuvenating pruning "on a stump", ie, the shortening of white turf bushes to a height of 15–20 cm from the ground to stimulate the growth of new shoots is done in early spring, before the beginning of the growing season. After pruning, it is necessary to sprinkle the hemp with ash to avoid infection.
Pruning and shaping the white turf bush
Full crown formation can begin after the shrub reaches the age of 3 years. Most often, white turf is used in group planting to form hedges, so the crown is cut in accordance with the chosen style: hemisphere, rectangle, etc. Separately growing ornamental bushes are most often formed in the form of various geometric shapes. Professionals often form a bush in the form of chess pieces, animals, a candle flame.
Preparing for winter
In view of the tremendous frost resistance of most varieties of this plant, no preparation for the winter period is carried out. It is enough just to cover the bush with snow. Only young bushes of non-frost-resistant varieties are dug up and stored in the basement in winter.
Blooming white deren
The shrub blooms quite beautifully. Small white or creamy flowers are collected in small inflorescences - shields. The size of each inflorescence depends on the variety and is about 5 cm.
Derain usually blooms in May or early June, but many varieties bloom again in early autumn.
Reproduction of white deren
This ornamental shrub can be propagated by any vegetative method:
- dividing the bush.
The seed method of reproduction is also acceptable, but it is not used due to the long periods of time. In addition, this method does not preserve the varietal characteristics of the plant.
How to propagate white turf by cuttings
In spring and autumn, cuttings can be harvested using strong shoots with well-developed buds. There should be 7-10 of them on each handle. They are usually rooted in early spring. The cut is processed with a weak solution of succinic acid. Then the cuttings are planted in a container with nutrient soil and placed under a film.
If rooting has occurred, all the buds will open and put forth new leaves. During the summer, it is necessary to periodically water and ventilate the container with cuttings, as well as feed them with a fertilizer solution or organic matter. By the fall, the seedlings will have their own developed root system and can be transplanted to a permanent place.
How to propagate by layering
Often, a plant takes root in this way on its own, if its growing shoots touch the ground. To obtain layering, it is enough in the spring to fix one of the flexible lateral stems at the surface of the earth and sprinkle it with soil. If the area is watered regularly, the shoot will take root and release a new shoot. After winter, the mother's shoot can be cut off, and the cuttings can be dug out together with a lump of earth and transplanted to another place.
How to propagate by seeds
Seeds are used for propagation only of pure forms of turf, since with this method of propagation, the young plant completely or partially loses all varietal characteristics. Seeds are harvested in autumn, from fully ripe fruits. As a rule, they have good germination. Disembarkation is carried out in the fall, usually in October, directly into the open ground. During the winter, they will undergo a stratification procedure, harden and germinate in the spring.
Diseases and pests of white turf
Diseases often affect young, fragile bushes, since adult plants have good immunity and rarely get sick. The greatest danger for him is powdery mildew - a fungal disease, to which all garden crops are susceptible to one degree or another. The fungus begins to develop from the lower part of the plant, gradually all of it becomes covered with a light bloom and brown spots, and then dries up and dies.
To avoid contamination, do not plant plants too close to each other. Watering should be done only at the root. In autumn, the root zone must be cleared of fallen leaves, since fungal spores can winter in it.At the first signs of the onset of the disease, the affected areas of the crown must be cut out and burned, and the bush must be treated with a solution of laundry soap, soda ash or infusion of garlic.
Of the insect pests on the white turf, midges, aphids and the comma-shaped scabbard most often appear. To combat them, insecticides are used (Decis, Karbofos), as well as infusions of wormwood, celandine, tobacco or onions.
White Derain is a versatile plant that can decorate a garden or park area at any time of the year. Unpretentious care, undemanding to the place of growth and soil composition, the plasticity of the crown and the rapid growth of shoots make it an excellent tool for both novice landscape designers and real high-level artists. It is also important that the seedlings of this shrub can be found not only in nurseries and shops. Often, grass grows near roads and rivers, in wastelands and abandoned areas. You just need to pay attention to it.
