Stranvaesia

About 10 species of evergreen shrubs and trees belong to the genus Stranvaesia. They are appreciated for the colorful foliage in spring and autumn and decorative flowers and fruits. David's Stranvaesia (Stranvaesia davidiana) - a species with oblong-lanceolate whole-edged leathery leaves, beautiful dark green color, in autumn when they wither, they acquire a crimson-red color that stands out against the background of other plantings. White flowers collected in scutes, resembling hawthorn flowers, bloom in May-June. The fruits are small rounded red, ripen in August-September. Of the varieties very common: 'Willow-leaved' with narrower leaves and noticeable venation than the botanical species; 'Wavy', less lush compared to the original appearance, leaves with wavy by the edge; 'Wavy yellow-fruited' with yellow fruits and 'Creeping', justifying its name. Glaucous Stranvaesia (S. glaucescens) has lanceolate or obovate glossy leathery green leaves with a finely toothed edge. Flowers collected in flat brushes, bloom in July. The fruits are bright orange, pubescent.

Cultivation

Stranvaesia is grown in parks and gardens, used in hedges. Due to their high adaptability to environmental pollution conditions, the plants are ideal for growing in cities. Plant on a permanent planting site in October or March (in cold climates). They prefer fertile and fresh, well-drained soil, fertilized with organic substances at the rate of 5-7 kg / m2. Once every 30-40 days during the growth period, a complex mineral fertilizer in the amount of 20-30 g per bucket is added to the water for irrigation (only young plants in pots). Pruning is not required only dry and damaged branches are removed.

Location

Stranvaesia can be planted both in the open sunny and in a semi-shady place.

Temperature

Plants are resistant to fluctuations in air temperature.

Watering

It is necessary during periods of drought and for young plants that have just been planted on the site.

Reproduction

Most often, in October-November, seeds are sown in a special soil, after which the shoots are kept for some time in an unheated room. Then they are planted one by one in new pots, which are filled with humus with fertile land and peat and fertilized with complex fertilizer at the rate of 30 g per bucket of soil. After several transshipments for 2-3 years, they are planted in the ground for fresh air. Semi-woody cuttings about 10 cm long are also used, which are taken in July from side shoots and planted in a mixture of peat and sand, and kept at a temperature of 16-18 °C. After the roots are formed, the seedlings are transplanted into pots and treated in the same way as the seedlings.

Diseases

Aphids and worms often cause damage to plants, which can be eliminated by treating them with appropriate medications. In a very sunny place and during dry periods, Stranvaesia is affected by a spider mite, which causes the leaves to dry out. Acaricide treatment is performed. Honeydew (Armillaria mellea) can cause root rot. Leaves affected by stereum purpureum become silver-gray in color. In both cases, the plants are removed. Plants are affected by the bacterium Erwinia amylovara (Erwinia amylovara), which causes a so-called bacterial burn (separate parts of plants unexpectedly drying out). In this case, contact your local plant pathology service, as this is a very serious and rapidly spreading disease.

Acquisition

Stranvaesia can only be found in specialized nurseries and horticultural centers that offer a wide range of crops. Buy plants that are small but well-developed - they tolerate transplanting well.
