In flower beds and garden plots, zinnia or, as gardeners call it, major, has long taken its place of honor. This flower was discovered by the Swedish naturalist Carl Linnaeus.
In the 18th century, European parks and squares began to be decorated with elegant, bright zinnia. And then they developed varieties and hybrids that could grow in different climatic conditions on all continents. Today, zinnia is actively used in landscape design. She is loved for her bright, varied palette.
Description and features of zinnia
A flowering shrub with branched erect or spreading elastic stems with a harsh edge blooms from mid-summer to late autumn. The heat-loving culture is afraid of frost and is unpretentious in care. Like many plants of the aster family, zinnia is not picky about the soil and loves good lighting. Depending on the variety, it grows from 20 cm to a meter. Majora's leaves are ovate with a pointed tip, dense, dark or rich green.
They grow oppositely or in whorls. The fruit is a triangular, flattened or oval achene.
It is used to decorate gardens and parks as an annual crop, although in the wild it is considered a perennial shrub. Grows in Mexico, North and South America. Breeders have bred abundantly flowering varieties of different colors and shades, the flower caps are flat or in the form of a hemisphere. The petals are reed-shaped, rarely grow straight, more often they curl into a tube, forming a terry bud, sometimes curling at the tip.
Flowering is multi-layered, lasts up to two months, and begins 50–55 days after emergence. In Russian conditions, agricultural technology of seedling cultivation is used.
The first row of outer large buds are flowers of the first stage, the seeds ripen in them, the rest are inside the bush, they bloom in the second and third stages, the seeds in them may not inherit the features of the species.
Where can dream grass grow?
In nature, this culture can be found in Siberia, the Caucasus or the Urals. In Altai there is even a specially created center for the speciation of lumbago. At the moment, experts are conducting research that will help them preserve sleep-grass.
In early spring you can observe flowering in the Leningrad region, the Baikal region and the Far East. The plant prefers pine, oak and birch forests. Can be used to create alpine slides and rockeries.
At the dacha, it is preferable to grow cultivated species. It is not always possible to do this from wild flower seeds. It is necessary to select the right material for sowing.
Types and varieties of zinnia
Existing garden classifications group numerous varieties of flowers according to their appearance into 4 species groups of zinnias: graceful, narrow-leaved, fine-flowered, linearis is separately distinguished, although in appearance it looks like thin-leaved myra.
Based on the length of the stem there are:
- tall zinnias, they are grown for cutting into bouquets, these are bushes from 60 to 90 cm in height. With good care and lighting, some varieties reach a meter in height;
- medium-sized, from 30 to 55 cm in height, they are bred for decorative areas;

Linearis is grown in apartments as a perennial potted crop; zinnias are unpretentious in care and are valued for their abundant long-term flowering.
Planting zinnias
The plant is heat-loving and does not tolerate frost well; only some selected varieties can withstand sub-zero temperatures.
Zinnias are grown from seedlings. It is kept at home or in a greenhouse until the end of return frosts. Sowing of seeds is carried out in March or April; it is convenient to sow zinnia in individual cups or peat tablets. The soil is purchased ready-made, universal or for tomatoes. The soil is made independently by mixing turf soil, river sand and humus in equal proportions.
Before planting, the seeds are checked for germination; sprouts appear within five days. Planting dates are selected according to the lunar calendar. The most convenient way to use peat tablets is to soak them without removing the reinforcing mesh. For planting zinnias, choose tablets with a diameter of 4 cm. In second place for convenience are individual cups; you can purchase cylindrical blister cups of 6–8 pieces. Deepen the seeds to a depth of 0.5–1 cm. When planting in groups, maintain an interval of at least 4 cm between plants. To ensure rapid emergence of zinnia seedlings, tropical conditions are created: the planting containers are well watered, covered with film, put in a warm place, the recommended germination temperature is +25...+27 °C.
Shoots appear in 5–7 days. The film is removed and the seedlings are transferred to a warm, illuminated place.
Features of growing zinnias
During the period of active growth of seedlings, fertilize with Agricola complex fertilizer for indoor plants. When general planting of seeds in a large container, plant picking is carried out after the appearance of the third full-fledged leaf.
The optimal growth temperature is not higher than +22…+24 °C, not lower than +17 °C. If the seedlings are very stretchy, they are given additional light, increasing the daylight hours to 14 hours. The plant blooms 2.5 months after the sprouts appear; seedlings are transplanted at the age of 4 to 6 weeks. During the growth process, lateral shoots are pinched and the top of the stem is removed. You can cut it with scissors; they are pre-disinfected.
Fertilizing during the growing season is carried out no more than once a month. It is advisable to choose complex ones, which include potassium, calcium, and phosphorus. Nitrogen fertilizers are applied in a limited manner so as not to provoke root rot. For feeding, superphosphate, ammophosphate, potassium sulfate, and ready-made fertilizers “Flower” and “Rainbow” are used. Before planting in the ground, the seedlings are hardened off - taken out to a cool place, allowed to spend the night in the open air, first under a fabric cover, then without it.
Caring for zinnia in open ground
The complex of agrotechnical measures includes weeding of seedlings, watering during the dry period, fertilizing during budding, removing shoots after flowering, new ones will form in their place. If the soil is dense, it is advisable to loosen it.
Only bush ornamental varieties are pinched. The stems for bouquet zinnias are left single, even, so that the flower has a marketable appearance.
Zinnia does not require care. It grows better in a well-lit place, but will also delight in shady areas.
Pests
Majors are afraid of caterpillars, scale insects and spider mites. But their main problem is powdery mildew and other bacterial diseases. They occur in the absence of ventilation caused by too dense planting or excessive watering. Therefore, the soil for them should be loose, well permeable to water. The moisture that remains on the buds and leaves after watering from above also contributes to the development of these diseases. If plants are planted densely in one place, then do not be afraid to remove a few weak shoots so that the rest develop normally. Also, don't overdo it with watering. Inspect plants and remove parts affected by pests.
Modern varieties of zinnia have been cultivated to increase resistance to powdery mildew, so if you follow planting and care recommendations, it is unlikely to bother you.
How and when to collect zinnia seeds
The cut seed heads are further dried until they crumble. After this, they are kneaded in the palms so that the seeds appear. They are sorted before packaging. Zinnia has a distinctive feature: different bushes can grow from one basket. This is due to the stage of seed development.
Only the elongated spear-shaped seeds with a pointed tip and the narrow ones with a grayish tip are left for planting. The brown, heart-shaped ones are thrown away; low ornamental base plants grow from them, even if the seeds are collected from terry bushes.
Experienced gardeners divide the seeds into groups. They choose spear-shaped ones for growing loose double and flat buds; elongated ones with a grayish tail usually completely inherit decorative characteristics.
The seeds are placed in bags and labeled with the year of collection, color, and variety. Store seed material at room temperature in paper. With high humidity, germination rate decreases.
Disease resistance
Don't forget about loosening the soil. This is important, especially after rain and watering the soil. This way you will ensure free access of oxygen to the root system of the flowers. This will allow the plant to develop fully and be more resistant to the formation of fungal infections.
By external signs, the sickness of plants can be determined by the white-grayish coating that appears on the leaves.
Zinnias are also prone to powdery mildew, root rot, and fusarium. Major pests also do not neglect them: snails, spider mites, aphids, slugs, chafers.
