Viburnum wrinkled (Latin Viburnum rhytidophyllum) - a species of the genus Kalina of the Adoksovye family. Asian, presumably Western and Central China. It is a frost-resistant species, is not popular in culture, although it deserves attention as an ornamental culture, has original foliage, and is suitable for landscaping Russian parks and gardens.
Characteristics of culture
Viburnum wrinkled - an evergreen shrub up to 3 m high with straight tomentose-pubescent shoots and a wide crown. Leaves are green, shiny, thickened, petiolate, opposite, rough to the touch, oblong-lanceolate, lanceolate or oblong-ovate, over the entire surface covered with a tomentose bloom of gray or yellowish color, up to 19-20 cm long.
The flowers are small, yellow-gray or grayish-white, collected in apical corymbose inflorescences, reaching 15-20 cm in diameter. Fruits are ovoid, initially red, later - black with shine, up to 0.8-1 cm in diameter, for food by people not used, but readily eaten by birds. The ripening period is different, both ripe and unripe fruits can hang on one brush.
The peculiarity of the species under consideration is that the buds on the plant appear in the fall, and bloom next spring, as a rule, in May. Viburnum wrinkled shade-tolerant, unpretentious to the soil composition, drought-resistant, but does not differ in rapid growth, especially in the early years. It is mainly used in single and group plantings.
The subtleties of growing
Like other representatives of the genus, wrinkled viburnum is photophilous, and at the same time tolerates partial shade. Desirable soils for cultivation are fresh, fertile, moderately moist, humic, neutral or slightly acidic. It can grow on other substrates as well, provided proper care and favorable weather conditions are observed.
Shrubs have a negative attitude to the piercing north winds and need protection. Despite the fact that the culture is hygrophilous and can be grown near water bodies, it will not tolerate flooding. It is not recommended to plant viburnum in lowlands, flooded in spring by melt water.
Viburnum is propagated by wrinkled-leaved seeds, cuttings and dividing the bush. The seed method of reproduction has a number of features, it is laborious, but it allows you to get high-quality planting material, which will subsequently quickly take root, and from the age of 5-6 it will bloom profusely.
Before planting, the seeds are subjected to a 6-month stratification with a change in temperature. At the same time, the seeds sown in spring will give the first shoots only in August, and the first cotyledons above the soil surface will appear in the spring of next year. For the winter, crops are covered with dry fallen leaves or peat for insulation. Still immature seedlings are grown in schools; to obtain lush bushes in the second year, low pruning is performed.
Pruning
Viburnum wrinkled leaves in need of annual sanitary pruning, consisting in the removal of broken, sick, frostbitten and damaged shoots. A good time for pruning is early spring. If the buds have started to grow, pruning is postponed until next year. Summer pruning is also undesirable.
Viburnum wrinkled is often used in uncut hedges, however it accepts formative pruning. When growing a bush-shaped viburnum, in the second year after planting the seedling in a permanent place, all branches are cut off by 2-3 nodes. When the shoots reach 30 cm, the growth points are pinched. From the awakened buds, several strong shoots will subsequently form, which will be the basis of the bush.
Pests and methods of dealing with them
One of the most dangerous pests of the wrinkled viburnum is the viburnum leafworm. The caterpillars of the pest devour buds and leaves, while wrapping them in a cobweb and knocking them into a ball. In case of untimely processing, the leaf roll destroys most of the leaves. To fight effectively, spraying with nitrofen (250 g per 10 l of water) or karbofos.
Occasionally, the culture is affected by the honeysuckle prickly sawfly. Pests appear during the blooming of leaves, they lay eggs on them, from which larvae subsequently hatch, which devour the leaves, sometimes to complete exposure. If pests are found, the bushes are sprayed with a solution of karbofos (100 g per 10 l of water) or infusion of wormwood or garlic.
The flowers of wrinkled viburnum can be damaged by a green lobed moth. Pest caterpillars gnaw flower ovaries. To combat them, use a solution of karbofos (100 g per 10 liters of water). Spraying is carried out before flowering.

Sly Wrinkled Sapwood
The wrinkled sapwood is very partial to any fruit crops. Especially unpleasant is the fact that these pests are capable of producing up to two generations per year. And they populate mainly weakened fruit trees, affected by frost breaks or sunburn, or with various mechanical damage to the bark. At the same time, cunning wrinkled sapwoods almost always inhabit only individual branches. And the small rounded holes that they gnaw in the bark vaguely resemble holes
