Deutzia grandiflora (Latin Deutzia grandiflora) Is a flowering shrub common in Korea and northern regions of China. Representative of the genus Deytsia of the Hortensia family. It is used for landscaping personal backyards and city gardens.

Characteristics of culture

Deutzia large-flowered is a deciduous shrub up to 2 m high with erect shoots, sagging under the weight of large flowers. Leaves are green, opposite, simple, whole, oval or ovate-elliptical, rough to the touch, covered with stellate hairs, up to 5 cm long. Felt-pubescent on the underside, with a whitish tint. In autumn, the foliage acquires an ocher color, remains on the branches almost until winter, becoming an additional insulation, both of the shoots and the root system.

The flowers are large, white, up to 3 cm in diameter, single or collected in inflorescences of 2-3 pieces. Flowering occurs earlier than other members of the genus. Duration of flowering is about 20 days. The fruit is a yellow-brown spherical capsule containing very small seeds. Non-frost-resistant, not prone to damage by pests and diseases. In Russia, it is grown as an ornamental crop, mainly in the southern regions of the country. Large-flowered action is suitable for cultivation in central Russia, but needs shelter for the winter.

Usage

It is used in single and group plantings, less often in uncut hedges. It goes well with other ornamental shrubs and trees, as well as annual and perennial flowers, including incense, horned goat weed, hosta and saxifrage. Low-growing forms are often used in border compositions, as well as for decorating garden paths. Looks great against the backdrop of the lawn.

Features of growing and planting

Despite the fact that the action is unpretentious to soil conditions, it is recommended to grow it on moist, loamy, mineral-rich soils with a neutral or slightly acidic pH reaction. The species in question grows well on poor soils, but to ensure lush flowering before planting and in the future, it is necessary to carry out regular fertilizing with both mineral and organic fertilizers.

In the presence of strongly acidic soils, preliminary liming is carried out, heavy clay soils - they arrange high-quality drainage with a layer of at least 15 cm. Negative action refers to the close occurrence of groundwater, but in this case drainage is sufficient. The location is preferably slightly shaded, the optimal areas are under the crowns of large trees with an openwork crown, which let in sunlight and retain moderate air humidity. Even if you plant a large-flowered action in an inconspicuous place, with the onset of flowering, it will transform it with beautiful flowers.

Planting seedlings of large-flowered action in open ground is carried out after thawing the soil, but before bud break. It is at this moment that the soil contains a sufficient amount of moisture, and the temperature conditions allow young plants to quickly take root in a new place. Planting holes are dug depending on the degree of development of the root system and its size, an approximate depth of 40 cm, excluding the drainage layer. When compiling the mixture, take the top layer of fertile soil, compost or humus and coarse sand (in a ratio of 2: 1: 1). The introduction of nitrophoska is encouraged.

Seedlings are planted at a distance of 1.5-2 m from each other, the distance depends on the type of formation. Planting too close can affect the flowering, it will not be so abundant due to the lack of light received. For strong thickening, pruning is required. In addition to removing thickening branches, frost-bitten and damaged branches are removed from shrubs every year - this operation is carried out in the spring, and also shortened faded shoots to a strong bud - after flowering. Rejuvenating plant pruning won't hurt either.

As you know, large-flowered deutzia is a drought-resistant plant, but the presence of a sufficient amount of moisture for it is a vital factor. The average rate of water used for irrigation of 1 adult shrub is 10-12 liters. Watering is carried out 1-3 times a month, depending on weather conditions. At the end of July, watering and other care procedures, including feeding, are stopped, this is necessary so that the shoots are properly prepared for winter. And with the onset of cold weather, the plants are wrapped in lutrasil or any other impenetrable material and tied with a rope. Shrubs below 1 m in height can be covered with spruce branches, but in this case, the bushes are bent to the ground.
