Kalina bureinskaya (lat. Viburnum burejaeticum) - a representative of the Kalina genus of the Adoksovye family. Previously, the genus was ranked as a member of the Honeysuckle family. Other names are Kalina Buryatskaya or Kalina Bureyskaya. Under natural conditions, it grows in North Korea, Northeast China, Khabarovsk Territory and Primorsky Territory. An adherent of rich and nutritious soils, it is found in deciduous, coniferous and mixed forests, mountain river valleys and on the slopes.

Characteristics of culture

Kalina Bureinskaya is a sprawling, highly branching shrub or small tree up to 3 m high with an openwork crown and a trunk covered with gray fissured bark. Young shoots are pubescent, light gray. Branches are glabrous, yellowish-gray. Leaves are dark green, simple, oval or elliptical, whole, slightly pubescent, sharp at the top, with jagged edges, up to 9 cm long.

The flowers are small, yellowish-white, collected in umbellate panicles, reaching a diameter of 6-7 cm. Fruits are drupes, have an ellipsoidal shape, contain one flat seed. At first, the fruits are greenish, as they ripen, they turn red, and then black or bluish-black. The fruits are edible, sweet, used in cooking. Bureinskaya viburnum blooms in June, fruits ripen in October. The culture enters fruiting only 6-7 years after planting, but subsequently blooms and bears fruit annually.

For the first three years, the shrubs do not grow rapidly; by the age of 20, the plants reach a height of 2–2.3 m with a crown diameter of 120–130 cm. Winter-hardy, relatively drought-resistant. Easily rooted by cuttings. The percentage of rooting when treated with growth stimulants is 85-90%. Unlike other representatives of the genus, Kalina Bureinskaya is photophilous and demanding on the composition of the soil, easily tolerates transplantation, regardless of age. Negatively refers to gas pollution and smoke, it is not recommended to grow Kalina Bureinskaya in urban conditions.

Subtleties of reproduction

Viburnum Bureinskaya is propagated by seeds, cuttings and layering. The seed method is very laborious and time-consuming, but effective. Allows you to get plants capable of producing high-quality harvests of berries with excellent taste characteristics. Seeds can be sown in the fall immediately after harvest, but in this case, the first shoots appear in about 1-2 years. At the same time, above the soil surface, a seed with a shell with which it leaves before winter is first pulled out, and only the next year the entrances will begin to grow in height. This process can be accelerated; for this, the seeds are subjected to three-month stratification. When the seedlings reach a height of 7-8 cm, they are transplanted into nurseries; young plants are planted in open ground next spring.

When breeding viburnum Bureinskaya by cuttings, the procedure for cutting the planting material is carried out in early June. Cutting is carried out using a pruner, the lower leaves are removed from the cuttings. For 10-15 hours, the cuttings are placed in a heteroauxin solution (to a depth of 2 cm), while the solution should not get on the leaves. At the end of the time, the cuttings are rinsed with clean water and planted in a nursery or greenhouse. Cuttings can be rooted not only in nurseries, but also at home. For these purposes, ordinary flower pots filled with turf soil, humus and sand in a ratio of 3: 1: 1 will do. Cuttings are planted to a depth of 2 cm, no more. The soil is moistened abundantly, and the cuttings are covered with plastic wrap. With the onset of cold weather, pots with cuttings are lowered into the basement, and first they are watered, but not abundantly. Until February, the cuttings are kept in a cool room, then they are brought into a warm room. Rooted cuttings are transplanted into open ground in May.

Pests and ways to combat them

Pests on Kalina Bureinskaya are frequent guests. This is largely due to unfavorable weather conditions or inadequate care. The most dangerous pests for Viburnum Bureinskaya are: honeysuckle prickly sawfly, viburnum leaf beetle, green lobed moth and viburnum gall midge. The fight against the viburnum leaf beetle is difficult. Leaf beetle larvae completely devour the leaves and literally in 5-7 days are able to destroy the plant. If leaf beetles are found on viburnum, they are treated with a solution of karbofos (at the rate of 100 g per 10 liters of water), but before flowering. Also, in the fight against these pests, infusions of bitter pepper, chamomile or tomato tops are effective.

The black viburnum aphid can also cause irreparable damage to plants. Aphid colonies settle on the leaves and suck the juices out of them, as a result, the leaves curl and the shoots are deformed. To combat aphids, root shoots and fallen leaves should be destroyed during the time; if pests are found on the leaves, they are sprayed with nitrophene (at the rate of 200 g per 10 liters of water), infusions of potato tops, celandine or capsicum. Honeysuckle flowers are often damaged by viburnum gall midge. Galiza lays eggs right in the buds, where they thrive. As a result of the defeat, the flowers become ugly, swell greatly and do not open. To combat gall midge, a solution of karbofos is effective (at the rate of 100 g per 10 liters of water). They cultivate not only the plant, but also the soil.
