Deytsia Vilmorina (lat. Deutzia vilmorinae) - ornamental shrub; a representative of the genus Deytsia of the Hortensia family. He is a native of the western and central regions of China.
Characteristics of culture
Deyzia Vilmorena is a flowering deciduous shrub up to 2 m high with a spreading crown and shoots covered with light brown peeling bark. Young shoots are pubescent. Leaves are green, whole, simple, opposite, lanceolate or oblong, rough to the touch, finely serrate along the edge, pointed at the apex, with a rounded or wedge-shaped base, up to 6 cm long. On the inside, the leaves are grayish, covered with dense radiant hairs.
The flowers are medium-sized, white, up to 2.5 cm in diameter, sit on stellate-pubescent pedicels, are devoid of aroma, collected in multi-flowered corymbose inflorescences. The fruit is a nondescript box, does not ripen in the conditions of central Russia. The deytsia Vilmorin blooms in June for 18-20 days. Distinctive features of the species in question are considered to be long and abundant flowering, an average growth rate and resistance to pests and diseases. Deyzia Vilmorin is drought-resistant, heat- and photophilous, cannot boast of winter hardiness, in severe winters it freezes without shelter.
The subtleties of growing
Deitia Vilmorena, like other representatives of the genus, is tolerant of various types of soils, however, it develops and blooms more actively on well-fertilized, moderately moist, light, loose, slightly acidic, loamy soils. On heavy, highly acidic, saline and waterlogged soils, it lags behind in growth and does not tolerate winters well. Negatively, the action of Vilmorin refers to shaded areas, as well as lowlands with stagnant cold air. When planting shrubs, you should avoid places where a large amount of melt water accumulates in spring. In addition, the plants need protection from the squally northerly winds.
Deutzia Vilmorena reproduces by seeds, green and lignified cuttings, root shoots and bush division. The seeds are very small, they remain viable for one year. Sowing is carried out in spring in seedling containers. With proper care and optimal conditions, seedlings appear in 4-5 weeks. With the appearance of three true leaves at the entrances, they are dived into separate pots filled with a nutrient mixture. Plants obtained by sowing seeds are planted in a permanent place after 2-3 years. After planting in open ground, young plants bloom only for 3-5 years.
The most effective way to propagate all types of action is by cuttings. Before planting, the cuttings are treated with growth stimulants, for example, Kornevin, in this case up to 50% of the cuttings are rooted. For the winter, rooted cuttings are covered with non-woven material. They are planted in a permanent place next spring. Planting is carried out in pre-prepared pits, at the bottom of which good drainage is laid. The voids in the pit are filled with a mixture composed of the upper fertile soil, humus, peat and sand in a ratio of 2: 2: 1: 1. The introduction of mineral fertilizers is not prohibited. If this procedure was not performed during planting, it is carried out in the summer, but until mid-July.
Care
The soil of the shrubs is regularly loosened and freed from weeds, the application of mulch is encouraged. At noon, young plants shade. Watering is carried out 1-3 times a month, based on the amount of precipitation. For one adult bush, 10-15 liters of water is enough. Pruning is carried out in early spring and after flowering. The first involves the removal of broken and dry branches, the second - shortening the faded shoots to the base or the first strong bud. Rejuvenating and thinning pruning is carried out as needed. Radical anti-aging pruning is also possible. The Vilmorin action is not cut.
For abundant flowering, annual feeding is required. In the spring, the action is fed with rotted manure or humus and complex mineral fertilizers. When growing shrubs on acidic soils, slaked lime is additionally added. The second feeding is carried out immediately after pruning. For these purposes, slurry (1 part of manure to 10 parts of water) and Kemira-wagon will do. You should not delay with the procedures for caring for the culture; in the second half of summer, all actions in relation to the shrubs are stopped, so they will have time to prepare for winter. And only in October they are bent to the ground, covered with spruce branches, and the foot is mulched with a thick layer of fallen leaves.
