Fraxinus

The genus Ash (Fraxinus) consists of approximately 70 deciduous trees up to 30-50 m high, with a trunk diameter of up to 1.5 m, resistant to strong winds. The crown is elongated-ovate, raised high, wide-rounded, with curved young branches. The bark is greenish at first, then gray or brown with age. The leaves are large, non-pinnate (complex, with 5-15 leaflets depending on the species), thin or leathery, with a serrated or serrated edge. Flowers are nondescript, collected in panicles, wind-pollinated, bisexual or dioecious. Only in some species, for example, in the flower ash, or white (Fraxinus ornus), and Chinese ash (f. chinensis), decorative flowers are collected in lush white inflorescences-panicles. The fruit is a winged achene (nut), hanging on the tree almost all winter (eaten by birds and carried by the wind). Tall ash, or common (f. excelsior), is the most common species everywhere. It is a tree with a straight trunk and a rounded crown. Its paniculate inflorescences are formed in the axil of the leaf scar of last year's shoot. Blooms even before the leaves open. Often suffers from spring frosts. It is widely used in gardening; it has decorative forms, for example, golden-with golden-yellow shoots; foliage turns light yellow in autumn. The weeping one has beautiful drooping branches; the wrinkled one has wavy wrinkled leaves. Flower ash is characterized by a peculiar low-hanging, often spherical crown and dense multi-flowered fragrant inflorescences. Complex leaves of the white American ash tree (F. alba) acquire a magnificent color in autumn, this species is of great practical importance. Fast-growing hardy species include the Pennsylvania ash, or downyash (F. pennsylvanica), and the lanceolate ash, or greenash (F. lanceolata).

Cultivation

Ash trees are used as ornamental plants in parks and gardens - in single plantings and in small groups, in landscaping, forest crops, windbreaks and for strengthening slopes. They are very resistant to atmospheric pollution; they tolerate dry conditions well. They are planted in autumn or spring (in cold climates, it is better in autumn, since the ground may not thaw in spring). Tall ash - a plant that is quite demanding of the soil-prefers fertile medium-and light loamy soils. But flower ash, on the contrary, is suitable for less fertile, even dried - up soils-both clay and calcareous. Pruning is only required for young plants when apical "forks" occur to form a single trunk.

Location

Ash prefers a location in the open sun, but also grows in partial shade.

Temperature

These plants are resistant to various temperatures; some species are sensitive to spring frosts.

Watering

It is only required for young plants immediately after planting or transplanting. During periods of prolonged drought, watering can also be useful for newly formed specimens. It helps maintain a lush crown and reduces the likelihood of diseases and pests.

Reproduction

They are propagated by seeds (in culture, the seeds must be stratified), root growth, and in culture also by cuttings. Sowing is carried out in autumn. Containers with seedlings are placed in a protected, unheated room. Seeds can take a very long time to germinate. As soon as the seedlings get stronger, they are planted singly in cups. For about 3 years, they are occasionally transferred to larger containers, after which the seedlings are finally planted. Flower ash can also be propagated by overgrowth, which it grows in abundance. Decorative forms do not retain the original properties of the species, so they are grafted in the spring to a rootstock grown from seeds of a botanical species.

Diseases

The causative agent of cancer (Neetva gebigena) causes the appearance of inflows on the bark of the trunk and branches of ash trees, which quickly swell, which leads to necrosis of tissues and subsequently to the death of the entire plant. If water stagnates in the soil, root rot may develop. Fungal infection (for example, tinder) penetrates the plant tissue through mechanical damage and wounds and causes wood smut. Characteristic fruit bodies are formed on the wood, leading the tree to death, so the diseased plant is discarded. Pests such as grape itch cause the appearance on the underside leaves and on inflorescences of small spongy galls (swellings). This is not a big danger. Ash trees are damaged by ash shpank (leaves), ash bast beetle (trunks and branches), ash weevil - seed eater.

Acquisition

Ash trees can be obtained in specialized gardening centers and nurseries. You can use seedlings with an unclosed root system. However, seedlings with a lump and plants in containers are better rooted in the ground. Choose small specimens without trunk forks and branches.
