Pruning viburnum buldenezh is an important operation that allows you to form a healthy, fast-growing and abundantly flowering shrub. The procedure is carried out according to a certain technique, depending on the season and the purpose of the haircut.
Ornamental shrub is unpretentious, with proper pruning and formation, it blooms profusely
Is the Kalina Buldenezh cut off?
Kalina Buldenezh (Viburnum Boulle-de-neig) is growing very quickly. The annual growth is at least 40 cm.If you do not engage in the formation of its crown, the branches will be located chaotically, as a result, thickets are formed that do not have an aesthetic appearance. Untimely and incorrect pruning leads to thickening of the bush, lack of proper ventilation, insufficient lighting in its center. As a result, the viburnum buldenezh begins to hurt, it is affected by pests, the branches dry and die.
With proper care, the shrub blooms profusely, decorating the landscape of the site for at least 20 years. Pruning is necessary for the plant to rejuvenate, the formation of larger foliage and inflorescences. For sanitary purposes, remove old, dry, diseased or damaged shoots.
Whether to cut the viburnum buldenezh after flowering
Blossoming of viburnum Buldenezh begins in early summer and lasts about five weeks. The snow-white inflorescences look very impressive, the diameter reaches 15 cm. Under their weight, the branches tilt downward, forming a cascade of white balls. The carved foliage of the shrub also looks decorative, the beautiful view of which remains throughout the season.
In the summer, pruning viburnum buldenezh can be done twice. For the first time, shoots that break out of the general shape are carefully cut to reveal the inflorescences hidden in the green foliage.
The second main pruning begins in mid-July, after flowering ends. During this period, you can start shaping the bush, giving it any shape in order to successfully fit into the design of the garden.
When pruning viburnum in summer, buldenezh first of all remove wilted inflorescences and lower, strongly bent shoots. Then pay attention to the branches inside the bush. Cut out those whose growth is directed towards its center.
If there is an impressive gap inside due to the lack of branches, one shoot is chosen next to it, a cut is made at an angle of 45⁰ above the kidney directed towards the hole.
Cutting the viburnum buldenezh after flowering must be combined with the treatment of the crown from pests and feeding the plant.
Some cultivars can reach heights of 4 m without pruning and shaping.
When can you cut viburnum buldenezh
Pruning is a traumatic operation, so it is best done during a rest period, when sap flow stops. The most favorable time begins after leaf fall and ends with bud break. In winter, it is not worth shaping the viburnum buldenezh, since its branches are fragile and it is easy to damage the plant.
Rules and schemes for pruning viburnum buldenezh
The pruning procedure is not considered difficult, but before you start forming the crown of a bush, you should read the general rules:
- The instrument is disinfected in advance.
- Branches with a diameter of less than 5 mm are cut with a pruner; for the rest, a lopper is used.
- The cut is made at an angle, 5 mm above the kidney.
- The wound is treated with garden varnish.
- Crown formation begins after the first year of life.
- When creating original forms, one should not deviate far from the natural, so as not to disrupt the natural development of the plant.
- Sick and frozen shoots are removed without pity, since in the future they can become a source of infection and provoke an outbreak of diseases.
- After pruning, damaged branches should be burned off site.
- The formation procedure is carried out at least twice a year.
The used garden tools (file, delimber, pruner, knife) must be of high quality metal, sharpened.
There are three types of ornamental shrub pruning:
- Formative.
- Anti-aging.
- Sanitary.
Depending on the age of the plant and its condition, the type of haircut is chosen.
After pruning the shrub, at least eight skeletal branches should remain
Formative
Determined with the future shape and height of the bush. Then they act according to the scheme:
- After planting, all shoots are shortened to three buds.
- New ones that have grown at the beginning of the season are pinched as soon as their length exceeds 30 cm.
- In the spring, the strongest branches are selected and their lateral growth is stimulated by pruning by a third.
- The shoots are cut out.
- The height of the main shoots is limited after they reach the desired length.
Rejuvenating
Pruning the old viburnum buldenezh is carried out no earlier than six years after planting. If the flowering has become weak, the leaves are small, and the berries are not tied, then it's time to rejuvenate the bush. For this purpose, the oldest branches are cut out (three to four per year). The plant will gradually renew itself.
Sanitary
This type of pruning and shaping is essential for the health of the plant. For this purpose, they remove broken branches or saw off their parts, cut out sick and dry ones, cut off clusters of berries.
In order to distinguish dry branches from living and healthy ones after leaf fall, you need to pay attention to the bark. On the dead, it is dull, covered with wrinkles or raised dots, and when scraping under it, you can see not green, but dry wood.
How to form a Kalina Buldenezh on a trunk
The viburnum shape, which has one trunk, looks very original. The challenge is to get a wide crown on a high or low stem. To form a viburnum buldenezh into a tree, you need to adhere to the pruning algorithm:
- After the seedling is rooted, you cannot engage in its formation for two years.
- In the third year, choose the strongest shoot, and remove the rest.
- Grow it for two to three years, removing side branches to a height of 40 cm.
- After the trunk reaches 1.5 m, the growth point is shortened by 30 cm.
- The next year, the resulting fork is pinched.
- Lateral branches are used to form the crown.
To improve the "healing" of the slices, they are treated with a solution of copper sulfate, and then with garden varnish
The tree looks impressive, but its trunk is often crooked, not strong enough and reliable. A gust of wind can break it. For strengthening, props are used - stakes, pipes, poles. Gardeners note that the yield of viburnum grown on a stem is slightly lower than that of a bush.
How to cut and shape Kalina buldenezh in spring
Spring pruning of viburnum pursues several goals at once - it is carried out for sanitary cleaning, formation and thinning of the bush. In addition to diseased specimens, frozen branches must be removed during this period. Their appearance is exactly the same as that of dry ones, they are cut off above the kidney.
In order to trim the Kalina buldenezh in the spring for the purpose of thinning, they act according to the plan:
- Tops are removed - shoots of the second order, growing vertically upward.
- All knots are cut out, the direction of growth of which is downward or into the bush.
- If the shoots rub against each other, only the strongest and healthiest are left.
- The umbrellas left over from the berries are cut off.
Formation and pruning are necessary for young viburnum. With their help, they give any kind of bush, including a tree. Spring is the best time for this. If you do not cut the viburnum buldenezh according to all the rules, soon its height will reach 2-3 m.To form a beautiful bush that is convenient for maintenance and harmoniously fits into the landscape, up to seven of the most powerful shoots are left, after which their growth is limited at the height of an arm extended up ... An ornamental plant can be cut into a ball, cube and hemisphere shape.
After spectacular pruning, viburnum can solo in single plantings, in compositions or serve as a hedge
How to properly cut and form a viburnum buldenezh after flowering, in the fall
When you start pruning in the fall, you should remember that you cannot predict what the coming winter will be like. With a large amount of snow, branches can break under its thickness. If the shoots are greatly shortened during autumn formation, frosts can complete the process and the entire viburnum bush will die. Avoid thinning pruning in the fall. A lush bush has a much higher chance of overwintering. During the winter cold, the branches protect each other from wind and frost. If the crown is dense, snow lingers on it and serves as an additional shelter for the plant.
In the fall, only dry, diseased and broken branches should be removed. They are cut to the healthy part above the kidney. It should be directed not inward, but outward of the bush. Broken shoots are removed on a stump, the cut is made parallel to the trunk with an indentation of 5 mm from it.
Depending on the age of the plant, autumn pruning and formation differ:
- Young bushes - in the first year, they only pinch the shoots.
- Old - remove branches of the second order growing up or down.
Conclusion
Pruning viburnum buldenezh requires special knowledge, skills and abilities from the gardener. It is not difficult to acquire them, it is enough to follow the recommendations. If the procedure is carried out in compliance with the terms and rules, the viburnum bushes after formation will look great, delight with luxurious flowering and a rich harvest of berries.
