Stockroza: features of growing from seeds, the rules of planting and care


Shtokroza (Alcea) - cold-resistant decorative-flowering annual or biennial, a genus of the Malvaceae family. Flowering time - July, August, September. Homeland is Asia Minor. There are more than 70 species in the genus. It can be used as a bouquet culture - cut in the phase of the bud quickly dissolves in water.

Stockroza: description and the best varieties

Four types of stockroza - pink, pale pink, Chinese and lobed, growing in China, Asia Minor, Turkmenistan and the Caucasus, served as the basis for the creation of modern varieties and varieties.

These are large plants with a tall peduncle, with a complex top-flowered spike-shaped inflorescence. Each corolla petal at the base fuses with the stamen tube, as a result of which the corolla falls completely. The flowers are sessile, simple, semi-double or double, various colors. Variegated forms are often found. Alternate leaves, palmate. Honey plant. The most popular varieties of this plant are presented in the table.

Growing stockroza from seeds: when and how to plant

Being considered a biennial, it is actually a perennial with a short life span. In the third year it does not die, but fades and loses its decorative effect. Grown from the seeds. Sometimes propagated by cuttings or division. In the first season it grows vegetative organs, in the second season it blooms.

Biennial seeds are sown in a nursery in May. After the formation of several leaves dive into the ridges at a distance of 20 cm from each other. You can also plant in earthen pots. In August, the plants are planted at a distance of 40-60 cm and left to winter. They tolerate winter well on dry, water-permeable, nitrogen-rich sandy loamy or loamy soils. Potted plants hibernate in cool rooms - basements or covered greenhouses. In May, pottery shtokrozy sent to the garden soil.

Rules for sowing seeds of shtroza in open ground:

  • the seeds are sown on a seedbed in late spring, when the soil warms up and dries out to the best;
  • the site should be well heated by the sun, located away from trees and shrubs;
  • good precursors for flowers are vegetables;
  • make peat in the garden, dig and loosen;
  • grooves are located at a distance of 15-30 cm from each other;
  • stockroses are sown in pre-moistened soil and sprinkled with a layer of 2 seed diameters;
  • a gap of 0.5 cm is left between the seeds;
  • seedlings must be thinned out - after the appearance of real leaves, leave 1 plant per 5 cm;
  • after 10 days - 1 for every 10 cm;
  • in autumn, seedlings are transplanted to a permanent place.

One-year stockroses sown in the ground in March will bloom in late August.

To bring flowering closer, seedlings are grown in containers.

  • preparing a soil mixture based on peat;
  • drainage is placed at the bottom of the tray,
  • soil level 1.5 cm below the edges of the dishes;
  • the soil before sowing should be moist, but not wet;
  • the seeds are laid out on the surface of the tray and sprinkled with earth through a sieve with a layer of 2 seed diameters;
  • the dishes are covered with paper with a loose structure, glass on top;
  • for germination optimum t 15-21ºC;
  • after emergence, paper and glass are removed;
  • watered by spraying.

After the first pair of true leaves appears, seedlings dive into pots or containers at a distance of 4 cm from each other. During a dive, the plant must be taken by the leaves, not by the stem. For two days, the seedlings are sent to a dark place, then kept in the light at t 10-13ºC. Watered according to the needs of seedlings. Hardening of seedlings is carried out, gradually lowering the temperature. Before planting in the ground, the seedlings are kept in containers in the garden for several days. One-year stockroza is planted in a permanent place in May.

Stockrose: landing and care

A plant with a tall, weak peduncle and large flowers requires garter. The support is installed at the time of transplantation to a permanent place. As a support, brushwood or a bamboo pole is suitable. The stem is strengthened as it grows. The flowering period will increase if faded flowers are removed in time.

Site selection and soil requirements

Shtokrose needs a sunny, sheltered from the wind. The soil must be well drained to avoid stagnation of water. The necessary amount of humus contained in the soil will allow moisture to be kept near the roots during drought. For the cultivation of stockroses, peat is not added to the substrate. In the fall, they prepare the soil - they dig it up, make organic fertilizers (rotted manure, compost).

How to dive stockroza

Landing technology

Between the garden and the lawn there is a drainage groove. Complex mineral fertilizers are applied to the topsoil one week before planting. The distance at planting is 45-60 cm. It is advisable to do mulching at the end of the planting, which helps to retain moisture, nourishes the soil with nutrients and prevents the formation of weeds. As mulch, rotted manure, leaf humus, crushed bark, and decorative chips are used. A layer of mulch is poured with a height of 5-7 cm. The aesthetic role is played by mulch from pebbles, gravel, and gravel.

Watering and feeding

Plants grown in containers do not have time to well develop the root system before dry days, so watering should be regular. When the soil dries 5 cm deep, it is necessary to carry out abundant watering. Daily watering with a small amount of water stimulates the germination of weeds. The soil cannot be kept constantly moist. - the surface should have time to dry in the interval between watering.

A plant requires approximately equal amounts of nitrogen, phosphorus and potassium. With normal flowering, top dressing is carried out in the middle of summer with complex fertilizers, in accordance with the instructions. Fertilizers should be applied to moist soil. If vegetative organs have strongly developed in stockroza, and the flowers are small and meager, fertilizers with a low nitrogen content and high potassium fertilizers must be applied.

Transfer

Shtokroza has a root root, so you need to correctly calculate the depth of the hole during transplantation. The roots should be freely located in the pit. Seedlings are watered 10-20 minutes before planting. Entangled roots are carefully spread with your hands - you can’t cut it. The top of the earthen coma should be located slightly below soil level. When planting, the plant must be held by the leaves or earthen lump and never by the stem. At the end of the seedlings watered from a watering can.

Disease prevention

It is susceptible to a mushroom disease - rust, especially in hot weather. Bloats of yellow-brown color are formed on the leaves and stems. The disease stops the growth and development of the peduncle and the entire plant. Infected leaves must be removed and burned. Plants sown with seeds in the soil are less affected by rust. For prevention, they are sprayed with Bordeaux liquid, copper chloride.

Cytadocides, the larvae of which feed on the sap of plants, harm Shtokrose. Cicadas are carriers of viral diseases. The result of the life of the parasites is the formation of mosaic pale spots or dots on the leaves. When cyclic plants are found, the plants are treated with actellic, diazinon.

The use of stockroza in landscape design

  • Like a flower bed plant, a stemrose adorns the flower garden from July to September. Tall and densely flowering, on regular flowerbeds of personal plots it can be used as a focal plant, surrounded by medium-sized background (20 to 40 cm high) and framing (up to 20 cm high) flowers. For a regular flowerbed, it is desirable that the plants bloom at the same time.
  • Shtokroza is used as a plant, masking farm buildings or planting.
  • Suitable for the design of long narrow beds, rabatok located along the fence or decorating the paths.
  • Shtokroza is used for summer flower beds.

Stockroza: sowing seeds for seedlings

Shtokroza is a hardy and unpretentious plant that does not require complex agricultural activities. Long inflorescences with large flowers of various colors look favorably in both monochrome and polychrome and contrasting garden compositions.
