Viburnum Buldenezh (Viburnum Boule de Neige) is the result of the work of French breeders. At the time of flowering, the bush amazes with its beauty and elegance, which has become the reason for the enormous popularity of the plant. Many gardeners are interested in how to propagate Viburnum Buldenezh, since it does not form seeds and is not found in the wild.
Optimal timing
Since the seed method is not available for propagating viburnum Buldenezh, only vegetative methods are used - cuttings, creating layering, dividing the bush. Each of them is used at a certain time of the year. According to the advice of professionals, layering is done in April and May to obtain new plants, cuttings are carried out in the spring or summer, and in the fall propagation is carried out by dividing the bush.
Translated from French, Buldenezh means “snow globe”
How to propagate viburnum buldenezh
As a result of breeding work, a sterile form of viburnum was created, which is not pollinated and does not form berries or seeds.The easiest way to propagate viburnum Buldenezh is by layering. It does not injure the mother plant and does not require much time. An adult seedling with a well-developed root system is obtained in the fall or next spring.
Cuttings are a more labor-intensive propagation process that requires adherence to deadlines, rules and rooting conditions. Planting material for this method is prepared specially or obtained after formative pruning of bushes. It will take two to three years to grow a full-fledged seedling.
Reproduction of viburnum Buldenezh by dividing the bush is the most traumatic and labor-intensive method. It does not provide a 100% guarantee of survival; plants are difficult to tolerate transplantation.
If during the process of growing a shrub a shoot has formed near the base, it can be carefully dug up and transplanted to a new place. Reproduction by shoots gives a good result only if the root system is sufficiently developed and is not disturbed during replanting.
How to propagate viburnum buldenezh by cuttings in spring and summer
Despite the fact that cuttings are the most labor-intensive of all methods of propagating viburnum, it is used more often than others. For this purpose, different planting materials are used - green or lignified cuttings.
How to cut viburnum buldenezh in summer and spring
To obtain new seedlings, you need to choose high-quality planting material. Use lignified or green cuttings. The first ones are received in the spring, the second ones in the summer.
To propagate the decorative viburnum Buldenezh by lignified cuttings, at the end of April - beginning of May, parts of branches up to 10 cm long that have bark are cut. It should be intact, smooth, without signs of disease, damage or breaks.The presence of rot or white plaque is unacceptable. The cuttings are cut so that each of them has two internodes.
In summer, bushes are regularly pruned to form a crown. It is during this period that green cuttings are prepared for propagation. They are taken from shoots that are no more than a year old. Choose only healthy, undamaged foliage with no signs of wilting or drying out.
Above the upper internode the cut is made diagonally, and below the lower one - straight
How to root cuttings of viburnum buldenezh
In order to accelerate root formation, cuttings of viburnum Buldenezh are dipped in water with the addition of heteroauxin (100 mg per 1 l) and kept in a growth stimulant solution for 6 to 10 hours.
For planting cuttings, prepare a substrate consisting of three components (sand, humus and turf soil), taken in a ratio of 1:1:2. All components are thoroughly mixed and pots or containers at least 10 cm deep are filled with the soil mixture.
Cuttings can be planted in open ground, having previously prepared the area for this. It is cleared of debris, dug up, all necessary components are added to the soil, and the surface is leveled. Planting material for propagation is planted in a row with an interval of 15 cm or one at a time in a container. The cuttings are buried in the soil up to the first bud at an angle of 60⁰. The soil is compacted a little and watered. In the fall, after rooting, the seedlings are transferred to a permanent place.
Before planting, the lower leaves of summer green cuttings are removed and the rest are shortened by half. For the winter they are securely covered with spruce branches and leaves, and with the onset of spring they are transplanted to a permanent place.

Planting viburnum buldenezh cuttings in open ground
Before planting viburnum seedlings Buldenezh, it is necessary to prepare an appropriate place for them. The shrub does not like intense light throughout the day. The fall of direct sunlight on the foliage ends with their curling and drying out. Too much shade leads to a reduction in flowering time and elongation of shoots. Viburnum Buldenezh feels great near a pond, in light, lacy partial shade. The soil should be breathable, loose, without stagnant water and swampiness. The optimal composition is loam or sandy loam with an acidity of 6 units.
If the soil is not fertile enough, add peat, compost, humus and mineral fertilizers. You can mix 500 g of wood ash, 200 g of nitrophoska and three buckets of humus.
To plant cuttings of viburnum Buldenezh, proceed according to the following scheme:
- Make holes the volume of which is twice the size of the earthen clod of the rooted plant.
- Drainage made of crushed stone, broken brick and expanded clay is laid at the bottom.
- The previously prepared soil mixture is poured on top.
- The seedling is placed in the center of the hole, its roots are straightened.
- Completely fill the hole with soil.
- Form a roller around the perimeter.
- Water generously with warm, settled water.
- Mulch the surface with leaves, bark and peat.
It is very easy to propagate Buldenezh viburnum from cuttings if you meet all the conditions and requirements for planting. Already in the next season, the shrub begins to quickly vegetate and bloom.
Aftercare
Further care for Buldenezh viburnum seedlings obtained using one of the propagation methods consists of watering, timely feeding, pruning, protection from diseases and pests. After propagation by cuttings and obtaining new plants, each of them requires regular watering. Water consumption is 30-40 liters for an adult bush and about 15 liters for a young one.
In the fall, moisture-recharging irrigation is carried out to prevent the roots from freezing in winter.
Feeding is carried out in the summer until the second ten days of August. Organic matter and potassium-phosphorus fertilizers are added. Annual pruning is carried out after flowering. The bushes are given a well-groomed appearance by forming a crown. In the fall, it is thinned out and damaged and diseased shoots are removed. In the spring, when plants are attacked by leaf beetles, bark beetles, moths, aphids and cruciferous flea beetles, the crown is treated with a solution of insecticides or an infusion of ash with the addition of laundry soap.
Reproduction of viburnum buldenezh by layering
Viburnum Buldenezh propagates not only by cuttings, but also by layering. The method is used in the spring, before flowering begins. They act according to the algorithm:
- A small hole is dug near the bush.
- Fill it with humus and add nitrogen fertilizer.
- Choose a long escape.
- Place it in the prepared hole.
- Fixed with staples.
- Cover with soil and lightly compact.
- Water generously.
After two years, the layering produces good growth. At this point, it is separated from the mother plant, dug up and replanted.
Reproduction by layering gives a high survival rate, does not require special care, the plant receives nutrients from the main bush.
The plant will bloom for the first time after two to three years.
Reproduction by dividing the bush
One of the easiest ways to propagate Buldenezh viburnum is by dividing the bush. From one mother plant you can get several full-fledged seedlings. This propagation method is used for viburnum, which is at least five years old, its root system is developed, and its crown is without signs of disease.
Division is carried out early in spring or late in autumn. Carefully dig up, shake off or wash off the soil from the roots with water. After inspection, they decide how many parts the uterine bush needs to be divided into. They are guided by the rule - each of the “divisions” must contain developed roots, several shoots and living buds. If it is impossible to divide into parts by hand, use a knife, pruning shears or shovel. To prevent rotting, the cut sites are treated with charcoal or activated carbon, after which new plants are planted in prepared pits in compliance with all rules. During the week, care should be taken to shade them to prevent burns.
Propagation by dividing the bush should not be used if the mother plant is very large
Recommendations and common mistakes
In order for the propagation of viburnum to give the expected result, it is worth listening to some advice from professionals:
- Sufficient illumination of viburnum ensures its abundant flowering.
- Heavy soil needs to be diluted with sand or peat.
- At the end of flowering, not only dry and damaged shoots are removed, but also faded inflorescences.
- To enhance bud formation, urea granules are added to the soil.
- When propagating by layering, shallow cuts are made on the bark of each of them to speed up root formation.
- For more luxuriant flowering next year, pinch out fresh growth in July.
Very often, gardeners follow all the rules for propagating viburnum, but years pass and it does not bloom. The cause may be excessive deepening of the root collar, excessive moisture, too much lighting or shading of the crown, fungal diseases and deficiency of macroelements. After eliminating these reasons, viburnum Buldenezh begins to bloom profusely every year.
Conclusion
To get many beautiful plants, you can propagate viburnum Buldenezh using one of the proposed vegetative methods. They are easy to implement and, if the rules are strictly followed, give good results. With the help of new seedlings, in just a couple of years the garden changes beyond recognition, looks more comfortable and impressive.
