Ornamental bushes are very attractive to gardeners because they not only decorate the area, but make it unique and cozy. Viburnum roseum is no exception; its bright greenery and white flower caps look great on a site decorated in any style.
History of selection
It is difficult to imagine any private home without viburnum growing nearby with its white inflorescences and scarlet berries that decorate the bush until winter. In the wild, the plant is distributed throughout the northern hemisphere. It was used in cooking and folk medicine. Later, breeders became interested, and as a result of their work, new varieties were created that differed from the original in the size of the bush, the shape of the inflorescence and other characteristics. Viburnum opulus Roseum is one of them. Scientists have developed an ornamental plant that pleases the eye with huge caps of flowers, but does not produce berries.
Description of the Roseum viburnum variety and characteristics
Viburnum roseum is a tree or shrub from the Adoskov family, 3 m high, with a crown width of up to 4 m. The shoots of the plant can be round or ribbed, their color is gray-brown, the core is white or yellow. The buds are red-green, with a pointed tip and two fused scales.
Viburnum Roseum blooms profusely - up to a hundred buds can bloom simultaneously on an adult plant
The leaves of Viburnum roseum are opposite, petiolate. Length and width - about 6 cm. The shape is three- or five-lobed with a heart-shaped base and diverging veins. The color is bright green, the structure is wrinkled on top, pubescent and velvety on the bottom.
According to the photo and description, Viburnum roseum produces snow-white flowers in the shape of balls. They appear at the end of May, at first they have greenish tints, and later turn white and slightly pink. The diameter of each is up to 15 cm. The crown of the plant is spreading, the annual growth is about 30 cm. The bush reaches its peak of development by eight years.
Viburnum ordinary Roseum is frost-resistant, easily tolerates temperatures down to -30 ⁰C, but in harsh winters with little snow it requires covering the base of the bush.
Reproduction methods
Viburnum roseum can only be propagated by vegetative methods. The method of cuttings, layering or dividing the bush is used.
By cuttings
One of the most effective ways. Cuttings are taken from viburnum in winter, when it is dormant. Take annual shoots up to 20 cm long, lower them into a container of water and leave for 3 hours. After this, the planting material is packaged in plastic wrap and placed in a cellar, basement or refrigerator until spring.In April, cuttings of Viburnum roseum are planted at an angle in the garden bed.
In the fall, the finished seedlings are transferred to a permanent place
Planting material for Viburnum roseum can be prepared in July, choosing the most flexible parts of stems 12 cm long with two buds. After keeping for 16 hours in a root formation stimulator, it is determined into a substrate of sand, peat and turf soil.
By layering
The easiest way to propagate the decorative viburnum Roseum is through vertical and horizontal layering.
In the first case, the lower branches of the bush are shortened to four buds, tilted to the ground and sprinkled with soil. In spring they produce young shoots. As soon as it reaches a height of 10 cm, it is covered again with soil. In autumn, seedlings of Viburnum roseum are separated from the mother plants and replanted.
Horizontal layering is made from long branches. They are bent down, placed in a small trench, pinned and covered with earth. Twice per season, the cuttings are covered with fertile soil. In the autumn, after rooting and growth formation, young plants of Viburnum Roseum are replanted.
Dividing the bush
The method is convenient only if the plant is not very bulky and can be easily dug up. The mother bush is carefully cut into several parts, the sections are disinfected and the roots are soaked in a growth stimulator for 2-3 hours. After this, “dividings” of Viburnum roseum are planted in compliance with all the rules.
Planting and caring for viburnum Roseum
In order for viburnum to take root as quickly as possible and begin to develop, it is necessary to comply with the terms and conditions of planting.It is equally important to choose the right place, prepare the soil and provide the plant with the necessary care.
Seedlings must be healthy and have a strong root system
Landing dates
Most often, Viburnum Roseum is planted in spring or autumn. The best time for planting in the southern regions is October or early November, just before the onset of frost. In more northern regions, seedlings are assigned to a permanent place in early spring, as soon as the soil thaws and warms up.
Requirements for place and soil
In the wild, viburnum most often settles near rivers and lakes, as it prefers moist soil. The same conditions must be chosen for Viburnum Roseum seedlings on the site. The variety feels good near water bodies, in places with high groundwater levels. It is shade-tolerant and grows well under other, taller trees or near fences and buildings.
The soil for viburnum should be loose and cultivated. Black soil, loam or sandy loam are suitable. If the acidity is above 5.5 pH, liming with dolomite flour (200 g per square meter) is necessary.
How to plant correctly
The appearance, splendor and strength of flowering of Viburnum Roseum in the near future depends on how correctly the bush is planted. The algorithm should be followed:
- Carefully dig up the soil to the depth of a spade bayonet.
- Make holes 60 cm wide and deep.
- Pour a large amount of water into the bottom if the soil is dry.
- Lay a drainage layer up to 25 cm thick of gravel, expanded clay, broken brick or tree bark.
- Prepare a soil mixture of turf soil, peat and sand mixed in a ratio of 2:1:1.
- Add 400 g of wood ash and a bucket of humus to the substrate.
- Pour the prepared mixture into the hole.
- Place the seedling in the center.
- Straighten out its roots.
- Fill the voids with soil mixture.
- Firm it up a little.
- Water generously.
- Mulch the tree trunk circle with wet sawdust, leaves or peat with a layer of 15 cm.

Aftercare
Viburnum ordinary Roseum is not demanding on growing conditions. Caring for her is not difficult. With regular watering, timely feeding and proper pruning, the plant will very soon delight you with powerful growth, beautiful, abundant and long-lasting flowering.
Watering
Viburnum roseum loves water, so drying out the soil is destructive for it. The soil in the tree trunk circle must be constantly kept moist. Otherwise, the flowers will be small and few in number, and the bush will stop growing and lose the bright color of the foliage and splendor.
Top dressing
The first time you need to fertilize the soil under the plant is two years after planting the seedling. Until this time, he will have enough of the nutrients that were added to the pit. The first feeding is carried out in the spring, during the period of foliage appearance. For one plant, 50 g of nitrogen, 20 g of potassium and 40 g of phosphorus are added.
At the beginning of autumn, potassium-phosphorus fertilizer is used to accelerate the maturation of young shoots of ornamental shrubs. For one plant, 40 g of phosphorus and 20 g of potassium are enough.
Trimming
For sanitary purposes and to rejuvenate the roseum viburnum bush, weak, dry and damaged branches are regularly removed.All shoots growing inside the crown and those whose length is more than 30 cm are cut out. As a result of cutting, a neat, beautifully shaped bush should be created.
To form a trunk, one trunk is left, all lower branches are removed
Pests and diseases
The most important pest of Viburnum roseum is the leaf beetle. At the end of May - beginning of June, the insect eats up all the leaf tissue, leaving only the veins, and lays eggs under the bark. The beetle does not give flowers a chance, eating the petals and depriving the bushes of their decorative properties. To protect against the pest, folk remedies are used - spraying with a decoction of garlic, nightshade and wormwood.
When the leaf beetle spreads massively, chemical treatments are carried out - “Intavir” or “Aktara”
You should not wait for Viburnum Roseum to bloom if it is attacked by other insects:
- viburnum gall midge;
- flower moth;
- lilac hawkmoth;
- comma scale insect.
The most effective remedy against insects is insecticides.
Among the most common diseases of Viburnum Roseum are powdery mildew and spotting. To combat them, preparations based on copper sulfate are used.
Application in landscape design
