Sorbus

The genus Sorbus includes about 100 species of deciduous trees or large shrubs. The leaves are alternate, simple, whole, pinnately dissected, lobed or unpaired, serrated or sawn at the edges, and acquire a striking yellow, red or orange color in autumn. From late spring to early summer, white or cream five-petaled flowers bloom, collected in lush corymbose inflorescences. Spherical apple-shaped or pear-shaped fruits are usually red or bright orange, often edible. Powdery mountain ash (Sorbus aria) is a shrub, sometimes a tree. The erect trunk is covered with smooth gray bark, can be separated from the base of the plant. The branches are pubescent. Simple oval biconvex leaves when opened are pubescent, silvery on the upper side, and later turn dark green and smooth, and on the reverse side they are covered with a whitish down; in autumn they acquire a brownish - red or golden hue. In May and June, creamy-white flowers bloom. In September, spherical orange-red edible fruits with a sweet taste ripen. Mountain ash American (S. americana) - a tree with branches turned up, which are covered with red sticky buds. The leaves are composed of 13-17 leaflets with a serrated edge. Small bright red fruits are collected in large brushes. The variety 'White-monte' is characterized by an egg-shaped crown. The tips of the leaves bend over time. Mountain ash (S. aucuparia) is a tree with a height of 4-15 m, with an egg-shaped crown, with a straight trunk covered with gray-brown bark. The flowers are white, blooming in May-June. The fruits are orange-red, ripen in September and get a color from orange-yellow to red. You can only eat fruits of the 'Edible' variety. The crop is cold - and drought-resistant, shade-tolerant. Mountain ash reduced (S. reducta) is a rare root-springing dwarf species. Compound leaves of 13-15 leaflets with a serrated edge, dark green, glossy, and in autumn they become bronzed and reddish. Small spherical fruits - white with a pinkish tint. Sargent mountain ash (S. sargentiana) is a slow-growing species, characterized by large bright red sticky buds. Large (up to 30 cm in length) leaves consist of 7-11 leaflets, which in autumn acquire an intense red color. The fruits are small, scarlet-red. Mountain ash species are cultivated as fruit and ornamental crops. The fruits of this plant contain sorbitol, carotenoids, and vitamin C.

Cultivation

Rowan trees are planted in parks and gardens and even on city streets. They prefer moist, fertile soils. The crop is winter-hardy; it is decorative during the flowering period and in autumn. Rowan trees are planted on a permanent planting site in autumn (in cold climates) or in spring. It does not tolerate air pollution from smoke and gases.

Location

Plants can be planted both in the open sun and in partial shade.

Temperature

These plants are resistant to temperature fluctuations, easily tolerate cold.

Watering

It is necessary only for young plants immediately after planting in the ground, and for adult plants during periods of drought.

Care

Cut out dry, damaged or unsightly branches.

Reproduction

Propagated by seeds, layers; in culture-cuttings and grafting. The most common method is sowing seeds. Seeds are extracted from the fruit, placed in a substrate (soil) in a cool room. After the seedlings germinate, they are planted one at a time in containers-pots. Then, for 2-3 years, from time to time they are transferred to new pots, each time larger than the previous one, and then planted in the open ground. Seedlings planted in the air are thinned out from time to time for 2-3 years, after which they are finally transplanted.

Diseases

On the branches of mountain ash can form a kind of influx; the affected parts should be removed. Rust appears on the leaves. In addition, mountain ash, like juniper, is affected by the same fungi of the genus Gymnosporangium, so avoid planting these plants side by side. Aphids and worms infect young shoots. In this case, treatment should be carried out with anti-aphid and anti-coccidal preparations, respectively.

Acquisition

The most common types and varieties of mountain ash are easily found in gardening centers and specialized nurseries. Choose plants that are small in size (they better tolerate the shock of transplanting), but already well-formed.
