Reproduction of viburnum is not particularly difficult if you know which methods are best for this, when to carry out the procedure and how to care for the plants. Therefore, in order to subsequently avoid serious mistakes, it is necessary to study all the features in advance. Only in this case, it is possible to grow new seedlings of this shrub without any problems.
For propagation of viburnum, vegetative methods are used
How viburnum reproduces
You can get new viburnum bushes in different ways. Each of them has certain characteristics, the observance of which allows you to get high-quality planting material.
The most common ones are:
- root shoots;
- dividing the bush.
The first method of reproduction allows you to get new seedlings in large quantities, but at the same time it does not guarantee the preservation of the varietal qualities of the mother bush. The rest of the methods give a limited number of young seedlings, however, they will fully correspond to the original type of culture.
Is it possible to propagate viburnum by cuttings
Red viburnum can be propagated using cuttings. This procedure is best combined with shrub pruning in order to obtain a sufficient amount of planting material. For some species, growing viburnum with cuttings may be the only breeding method that will allow you to preserve your favorite variety. But for it to be successful, it is necessary to study the features of its implementation.
How to propagate and grow viburnum from cuttings in spring, autumn
Propagation by cuttings allows you to get a sufficient amount of viburnum planting material, fully preserving varietal qualities. Therefore, this is the method used by professionals.
Viburnum propagation is possible by green and semi-lignified cuttings. The first method is used in the spring, and the second in the fall. Each of them has features that you need to pay attention to in order for the procedure to be successful.
Semi-lignified cuttings need to be saturated with moisture for successful storage until spring
How to cut viburnum ordinary
Harvesting of planting material in the spring should be carried out in May. To do this, you should select young green shoots 10-15 cm long. It is recommended to cut them off from the branches with a "heel", since in this case they take root better.
For autumn cuttings, you need to choose semi-lignified one-year shoots. They can be identified by the lighter shade of the bark. For propagation, use the middle parts of the branches 10-12 cm long with two or three nodes.
Important! For successful reproduction and rooting, the lower cut of the shoot must be made oblique under the bud 1 cm lower.
How to root and plant cuttings
To plant green cuttings, you need to prepare a shaded area on the site. The bed should be previously loosened and added to the soil humus and sand at the rate of 5 kg per square meter. m. When planting, the lower cut must be powdered with any root former. Place the cuttings 5 cm apart. Plant them in a well-moistened soil and compact the soil surface at the base. For successful rooting, you need to make a mini-greenhouse from above.
Planting viburnum cuttings for the winter is not carried out. The seedlings harvested in the fall must be soaked in water for several hours. Then tie the planting material in a bundle and put it in a damp cloth, and wrap it on top with polyethylene with holes for ventilation. The resulting package should be stored until spring on the bottom shelf of the refrigerator.
At the end of February, propagation cuttings must be planted in prepared containers filled with peat, turf and sand in equal quantities. It is necessary to deepen the lower cut by 2 cm. It is recommended to place the shoots at a distance of 4-5 cm. At the end of the procedure, cover the seedlings with a transparent film. At first, the cuttings of viburnum should be kept at a temperature of + 27-30 degrees and the humidity should be maintained at 90%, regularly spraying the seedlings.
Viburnum cuttings take root in three to four weeks
Throughout the season, it is necessary to maintain optimal conditions for plant growth. They should be watered regularly when adding the top layer of the earth. It is also necessary to ventilate the landings and remove the collected condensate from the film.
When the viburnum cuttings grow, they should be adapted to external conditions. To do this, it is necessary in the first days to remove the shelter for 2-3 hours, and with each subsequent time increase the interval by another half hour. After a week, the mini-greenhouse must be completely removed.
Young viburnum seedlings can be transplanted to a permanent place only next spring. They will begin to bear fruit at the age of five.
Important! You can plant autumn cuttings in open ground when they are strong enough.
Viburnum propagation by seeds
The seed method of propagation of viburnum is rarely used by gardeners, since the obtained seedlings do not retain varietal qualities.
Viburnum seeds in the spring remain viable for two years
There are two ways to grow seedlings in this way. In the first case, immediately after picking the berries in the fall, you need to remove the pulp from them and get the seeds. Then prepare a bed in the shade of shrubs or trees, where the soil is constantly moderately moist. To do this, you need to dig up the area and add humus and sand, 5 kg for each square. After that, make furrows 3 cm deep and plant seeds in moistened soil. When planted directly in open ground, they will naturally stratify in winter and germinate after 18 months.
To speed up the process of growing viburnum with the seed method of reproduction, it is necessary to carry out rapid stratification. To do this, put the freshly harvested and peeled viburnum seeds in a nylon stocking and place them in wet moss or sand. The first two months they need to be kept at a temperature of + 18-23 degrees, and then for 30 days at a mode of +4 degrees.
At the end of the stratification, the seeds must be planted in containers filled with a nutrient mixture of sand, peat and humus, without burying the hypocotal knee into the soil. At the end of the procedure, moisten the substrate and keep it in a shaded place with a temperature of +20 degrees, covered with a film. At the end of winter - at the beginning of spring, when the shoots will break through, the container must be rearranged on the windowsill and the mode must be lowered to +18 degrees.
Over the next year, they need to be kept at home, and planted in open ground only next spring.
Important! When the viburnum is propagated by the red seed method, the shrubs begin to bear fruit in the sixth or seventh year.
Reproduction by layering
You can propagate the red viburnum bush with horizontal and vertical layering. In the first case, in the fall, it is initially necessary to loosen the soil under the plant to a depth of 5-7 cm. And with the arrival of spring, bend the young side shoots to the soil, deepen it completely by 5 cm and fix it with brackets. Subsequently, when young shoots grow up to 20 cm, you need to spud them. Repeat the procedure several times per season, which will allow the layers to build up a powerful root system. With the arrival of autumn, the seedlings can be detached from the mother bush and planted in a permanent place.
Bushes grown from cuttings are 100% survivable
The second method of reproduction is that in the fall it is necessary to cut off the lower branches of the shrub so that no more than two to four buds remain on them. And then sprinkle the plant with fertile soil to a height of 15-20 cm. With the arrival of spring, sprouts will appear from the buds left. When they reach a height of 10-15 cm, you need to huddle them by 4-5 cm, repeat the procedure several times per season. In autumn, separate the matured seedlings from the mother bush and transplant to a permanent place.
Important! Reproduction by layering does not require complex actions, therefore it is especially popular with novice gardeners.
Reproduction by root shoots
You can get new seedlings of red viburnum by root shoots, which are formed at the base of the bush. To do this, in early spring or early autumn, you need to disconnect well-strengthened specimens with root processes. After the procedure, they can be immediately transplanted to the prepared place and watered.
Reproduction by dividing the bush
This propagation method is used for shrubs over six to eight years old. It is necessary to dig up the red viburnum in the fall and divide it into several parts. Each of them should have three to four shoots and well-developed root processes. At the end of the procedure, the open wounds on the "parcels" should be sprinkled with wood ash so that they do not get infected. And then plant the seedlings in a permanent place.
Dividing the bush to rejuvenate the plant
Viburnum propagation can be carried out in different ways, and each of them makes it possible to get a sufficient number of young plants, if you follow all these instructions. Therefore, if desired, even a novice gardener is able to grow new bushes of the crop variety he likes without much difficulty.
