Viburnum of Sargent Onondaga: description and care of the variety
About 170 varieties of decorative and fruiting viburnum are known in the world. Most often, this plant is found in the temperate latitudes of the northern hemisphere, less often - in Madagascar, the Antilles and the Andes. The view of Sargent includes 7 subspecies, the most famous of which is Sargent Onondaga, which will be discussed in the article.
Viburnum cultivar Sargenta Onondaga is a fast-growing strongly branched shrub reaching a height of 2.5–3 m. The width of the crown habitus usually corresponds to the height of the plant, sometimes exceeding it.
Old lignified root shoots have a brown color with a reddish tint and can grow up to 5 cm in diameter. Lateral branches differ in burgundy color, which is a characteristic feature of the Onondag subspecies.
The leaves have an unusual wedge-shaped shape. In the early stages of growth, they have a reddish color, when they bloom completely, become dark green with a burgundy shade in the central vein. In autumn, the color changes to yellow and red. The back side of the sheet has a slight edge.
Flowering culture lasts from late May to mid-June. Fragrant flowers are collected in large thyroid inflorescences, around which there are large sterile (asexual) pinkish-white flowers, in the middle - bisexual (fruit-bearing) red-burgundy color. The plant is a good honey plant.Edible berries, with an average weight of 0.5-0.6 g, ripen in late September. The color is orange-red with subtle touches. The culture tolerates winters well, but immature annual shoots can freeze in severe frosts.
In traditional medicine, berries, flowers, leaves and bark of viburnum of Sargent Onondag are used.Leaves and young shoots have a sedative effect on the body.The bark is used as a hemostatic, especially with uterine and heavy menstrual bleeding. In addition, it has astringent and diuretic properties, it is used for diarrhea, scrofulosis and respiratory diseases. This variety is characterized by the natural bitterness of the fruit due to the presence of iridoids, or bitter glycosides - biologically active substances designed to have a wound healing, antimicrobial, sedative, diuretic improve digestion and increase appetite.
Did you know? Unripe berries of viburnum can cause vomiting, as well as overeating of ripe fruits.
Landing and care
Viburnum of Sargent Onondag, like most of its relatives, is very moisture-loving, therefore, for planting, it is preferable to choose lowlands near water bodies. It does not tolerate prolonged exposure to sunlight - abundant flowering and fruiting can only be achieved in shaded areas.
The soil for planting the crop should be fertile, well-fertilized, lightweight and loose. If the soil on the site does not meet the requirements, you will have to work on it: heavy clay is lightened with sand, light clay is weighted with clay, acidic clay is quenched with lime.
Did you know? Each viburnum bush for full development must have at least 4 m² of free space.
After choosing a place and planting material, you can proceed with the landing:
- Dig a hole with a depth of 50 cm and a diameter of 60 cm.
- Equip the drain by pouring a layer of expanded clay or crushed stone at the bottom.
- Mix the earth with a bucket of compost or humus, a glass of wood ash and half a glass of nitrophoska, fill this hole with half the half and form a small hill.
- Plant a seedling, evenly spreading the roots on the hill.
- Fill the hole with earth to the top so that the root neck of the seedling is 3 cm submerged under the ground.
- Level and compact the soil.
- Make a trench for irrigation around the circumference of the hole with a depth of 10-12 cm, fill it with water. At least 2 buckets of water are required to irrigate one seedling.
- When the moisture is gone, level the ground again and mulch with humus or peat.
Shrub care does not require much skill, effort or time. To ensure abundant flowering and fruiting, you need:
- provide timely plentiful watering and top dressing;
- weed, loosen and mulch the soil;
- to trim;
- protect the plant from pests.
Viburnum does not tolerate drought, so it is planted in marshy areas and in close proximity to water bodies. If this is not possible, it is very important to water the plant as often as possible in order to prevent the soil from drying out.
Important! Moisture should reach the ends of the roots, so for watering every time you need to dig a trench around the circumference of the crown, which corresponds to the diameter of the root system. The older the bush the larger the diameter of the trench.
Feeding plants is recommended once in mid-August. To do this, use a mixture of 150 g of potassium and 80 g of phosphorus per bush. Fertilize in the trench for irrigation.
Weed weeding is required mainly for young plants. Later, when the crown grows, it will completely hide the circle underneath it, practically not letting in the sun, and weeds can no longer prevent it. The same rule applies to loosening and mulching.Sargent Onondaga variety is highly immune to various diseases and pests, so preventive treatments are not required.
Viburnum can be propagated throughout the growing season, but at different times of the year different methods are used. In spring, the culture is propagated by layering, in summer - by dividing the bush, in autumn - by cuttings.In order to get layering, you need to dig a small ditch, lay an annual shoot in it so that the top with 4-5 kidneys remains above the ground, secure with a bracket and sprinkle with earth. By autumn, the shoot will develop a powerful root system. It will only need to be separated from the trunk, dug up and transplanted to a new place.
Bush division - An effective method, but not very popular. To propagate viburnum in this way, you need to completely dig out the bush, divide it into several parts so that each layering has a full root root shoot and the root itself, and plant it in separate holes. This is easy to do, but, firstly, this can only be done with young plants up to 5 years old, and secondly, you won’t get berries in the first 1-2 years.
For the propagation of viburnum by cuttings, it is better to use annual non-lignified shoots. They are cut off during the flowering period, divided into several parts so that each of them has 2-3 nodes. The upper sections should be straight, the lower - oblique.Leaves should be left only in the upper part, shortened to half.
Ready cuttings are planted in greenhouses under a film or glass, preparing a fertile soil and moistening the soil well. Before the fall, you need to monitor the microclimate: it is important that the greenhouses are humid, warm and direct sunlight does not fall there. By autumn, cuttings will take root, and they can be transplanted.
Stump Trimming Rules
Kalina easily tolerates any trim, but only until the beginning of August. After the buds begin to be laid for the next vegetative period, it is no longer recommended to touch the plant. The optimal time for anti-aging and sanitary trimming is March. At this time, you need to remove all damaged, frostbitten, sick and bent inward branches.
Viburnum lives up to 50 years, but at some point it can begin to bloom and bear fruit poorly. In this case, pruning to the stump helps radically rejuvenate the plant, which is carried out in 3 stages over 3 years. For this, in the early spring, before the sap flow begins, in the first year a third of the shoots are cut under the root, leaving stumps 5–7 cm high. Another third are cut in the same way in the second year, the rest in the third.By this time, young shoots will already grow from the stumps of the year before last, which will be the first signs of complete rejuvenation of the bush.
Important! To avoid infection and speed up the regeneration process, all places of the cuts must be disinfected with copper sulfate and gloss over with garden var.
Viburnum of Sargent Onondaga is designed not only to decorate gardens and parks, but also to help people fight many diseases. Planting this plant and caring for it is not difficult, and the result will clearly justify all the work put into it.
