When to plant cosme seeds for healthy seedlings

Kosmeya, or cosmos, is a herbaceous one or perennial plant from the Astrov family, while the flower looks like an ordinary chamomile. It is widespread in horticulture for its beautiful and long flowering period from June to the end of October, and is also famous for its unpretentious cultivation. Cosmey is easier to propagate by seed, therefore it is important to take into account when to plant cosmey when growing from seeds and how to care for it in the future.

Popular species and varieties with photos

Kosmeya comes from the tropics, so it takes root better in warm climates. The most common in our territory are two types:

On their basis, many varieties and hybrids were obtained. The following are popular among our gardeners:

Terry varieties include: Rose Bonbon, Psyche, Snow-White Marshmallow, Terry Button.

Reproduction from seeds

Despite the large and varied assortment of varieties, all of them are united by a single method of reproduction - by seeds... They can be planted directly in open ground. If you want to get early flowering, it is recommended to grow cosmea through seedlings. Sowing is carried out in late March or early April. Auspicious days according to the lunar calendar: March 15, 16, 21, 22 and April 6.

With this planting time, flowers bloom in early June.

Seed material is sold in florist shops. If such flowers are already growing on the site, then it is easy to collect the seeds yourself. This is done in the fall after flowering is complete. They retain good germination for 3 years.

For the cosmos, the landing site matters. The site should be well lit. The soil is preferable fertile, loose and fresh. A high content of organic fertilizers and sand is encouraged. It is recommended to dilute heavy soil with sheet compost.

Growing seedlings: step by step instructions

Any planting container will do, but with drainage holes at the bottom. It is not necessary to take too deep. If you do not need a lot of seedlings, then it is preferable to choose small pots or cups designed for a maximum of two seeds. The substrate can be purchased for seedlings or made independently. For this, loose and light earthy compositions of medium nutritional value are mixed.

Sowing technology of seeds of cosmos:

  1. The containers are filled with a substrate and moistened from a spray bottle. It is undesirable to seal.
  2. The seeds are evenly distributed from above, adhering to an indent of 10 cm (if the boxes are large). Then it is pressed lightly.
  3. Spray with water from a spray bottle.
  4. Cover with glass or stretch the film.
  5. Seedlings are placed in a bright place.

In the warmth, the kosmeya germinates worse, so the optimal temperature is from 14 to 18° C.

As soon as 2-3 leaves appear, they start picking. This is subject to germination in a large-scale container.

If the seedlings grow in separate pots, then the procedure is not required. If it is not planned to preserve all the planted material, then thinning is dispensed with: they pull out the weakened shoots and leave only the strong ones. In case of intensive growth of seedlings, it is recommended to pinch the tops, which will contribute to lateral branching. Additionally, they organize the backlight.

2-3 weeks before transplanting into the garden, the seedlings begin to harden: they are taken out daily for 1-2 hours to fresh air.

Planting in open ground and further care

The transplant is carried out when the weather is stable outside and the risk of night frosts passes. This usually happens at the end of May. Seedlings are planted with an indentation of 15 to 30 cm. In close proximity, the flowers begin to stretch intensively in height and bloom worse. Since the plant is hardy and is not afraid of transplanting, you can not be afraid to damage the roots.

Kosmeya is surprisingly drought-resistant, but at an early age it especially needs abundant moisture. Therefore, the first time it needs to be watered regularly, preventing the upper soil layer from drying out. Especially watch out for moisture on the eve of and during flowering. Thus, it is possible to stretch this colorful period.

Fertilizing during the growing season is optional. Professional growers advise to feed the plantings at the budding stage, using mineral formulations with a minimum nitrogen content, otherwise there will be a lot of greenery to the detriment of flowering. This procedure is repeated several times over the summer. A tall cosmea must be tied to a vertical support. It is better to remove the first flowers immediately so that the subsequent ones bloom more abundantly and longer.

To obtain seeds, several of the largest buds are left.

Due to its high adaptive ability, kosmeya rarely gets sick and is affected by insects. If any problems arise during cultivation, then they are mainly associated with improper care or unfavorable weather conditions.

The diversity of the available varieties of cosmeas allows you to choose an option to taste. Flowers are used everywhere in the design of personal plots. Despite their simplicity, they look advantageous both in isolation and in compositions. Cosmos are made out in the form of beds or as a background for a flower garden or hedge.

Kosmeya flower photo Growing from seeds

Kosmeya (sometimes written kasmeya, also called space, Mexican aster) is a herbaceous plant of the Asteraceae family. In its natural environment, it occupies vast territories of South and Central America, was brought by the Spaniards to Western Europe, where at present it not only decorates gardens, but also grows wildly along roads, fields, in wastelands.

Botanical description

The stem height is 50-150 cm. It is thin, erect, branched. The leaves are openwork, threadlike. The inflorescence inherent in all Compositae: the core consists of numerous tubular yellow flowers, and what we call a petal is actually a separate inflorescence.

These "petals" are oval in shape, elongated, the edges are slightly dissected. The color can be white, pink, yellow, red, dark red. At the top of the stem, the inflorescences are located singly or in several pieces. Fragrant flowers attract pollinating insects.

When it blooms

Flowering lasts all summer until the onset of severe cold weather. The fruit is a densely seeded achene.

In our latitudes, kosmeya is grown as a one - and a perennial plant.


Description of the plant

Kosmeya belongs to the Asteraceae family. In our climatic conditions, these are annual plants. In their natural conditions, many species are perennial. In the natural environment, the species is found in many regions of the world - in North and Central America, Asia, the Caribbean. These are flowers with soft, threadlike, green and feathery leaves that resemble dill. They have very low soil, cultivation and maintenance requirements and bloom beautifully all summer.

This species came to Europe from America at the end of the 18th century. However, only a hundred years later, they fell in love with the cosmos and it began to expand to the entire continent.

The name of the plant comes from the Greek word "kosmos", which means order, decoration.

Some say that the kosmeya owes its name to the height: it reaches 1.5 m. Others believe that the missionaries gave the name to the plant, the center of which resembles the Sun, surrounded by petals that look like planets. There is an opinion that the origin of the name is inexplicable, just as the cosmos is inexplicable.

Kosmeya grows up to 100-150 cm, has a straight, branched crown. The leaves are small, feathery, light green. Flowers are collected in large baskets with a diameter of about 9 cm. Flowers differ in structure, color, depending on the species and variety, there are - white, pink, purple, bright red, yellow. The plant blooms profusely from July to October. The fruit is seeds.

In the garden, kosmeya begins to grow when the last spring frosts have passed. Even without leaving, it grows and blooms from July until the first frost. The flower looks simple enough, but it perfectly decorates flower beds and flower beds.


Botanical description

The kosmeya plant reaches a height of 50 to 150 cm. Its stems are thin, flexible, erect and branched. Leaves are opposite, twice dissected, delicate, graceful. Inflorescences-baskets, similar to chamomile up to 12 cm in diameter, grow singly or are collected in loose corymbose panicles. The middle flowers in the baskets are small, tubular, yellowish, and the reed flowers are large, purple, pink, red, white, golden yellow.

  • You can often read or hear the expressions “terry kosmeya flower” or “terry kosmeya cultivation”, but this does not mean that we are talking about a separate species, just in recent years breeders have bred terry varieties of plant species that have been cultivated for a long time. The fruit of the cosme is a dark yellow, gray or brown achene. Cosme seeds remain viable for two to three years.


    Variety selection

    Until the end of the 20th century, on the territory of Russia, the widespread cultivation of Cosmeas of the same species, with elongated peduncles, a simple structure of medium-sized flowers and a color limited to several shades of pink and white, was practiced. The simplicity of growing from seed and self-sowing of the plant made it possible to obtain lush flower beds without much maintenance.

    Modern selection has presented gardeners with a huge selection of hybrids for growing. Different varieties of Kosmeya differ in bush height from 25 cm to 2 m, double and semi-double inflorescences, flowers of small diameter or larger than 12 cm.The petals can be grown together in the form of a bowl, strongly dissected or even rolled up like shells.

    Of more than 25 varieties and hybrid forms of Cosmea, domestic gardeners are most in demand for seeds of three varieties.

    Cosmeya double-feathered

    Another name for this Cosmei is Chinese chamomile. A viable variety, popular throughout the post-Soviet territory, is capable of self-seeding even on uncultivated lands. Easily propagated by seeds, unpretentious when grown in gardens, in public flower beds.

    A tall, openwork bush of double-feathery Cosmos is distinguished by light green, filiform foliage, branches densely, grows up to 2 m. The flowers are large, with a diameter of about 12 cm, single or collected in sparse shields. The marginal petals are single-row, the middle is yellow.

    Seeds of double-feathery Kosmeya tolerate cold winters well. They can be sown both in spring and autumn.

    The color of the flower is from snow-white to wine-red and purple. On the basis of the double-feathery, new hybrids of Cosmea are constantly being created.

    Kosmeya sulfur-yellow

    The lesser popularity of yellow-orange varieties is due to their thermophilicity. Good results are obtained by growing sulfur-yellow Cosmos in the open air in the south. In more severe climatic zones, seeds are recommended to be planted in containers, so it is easier to take the plants indoors when cold weather sets in. The culture does not tolerate cultivation in a humid climate with winds and a lack of sunlight.

    Small-sized flowers (up to 8 cm) are characteristic of the sulfur-yellow Kosmea. The leaf blades are darker and less dissected than that of the double-pinnate, with pointed ends at the ends. Shoots are slightly pubescent, strongly branched. An adult bush of the yellow cosmos grows up to 120 cm in height.

    Abundant flowering. The ligulate marginal petals range in color from lemon and golden yellow to bright red. The median tubular flowers have orange tips and long anthers.

    Kosmeya chocolate

    The culture is perennial, but this quality can be preserved only in the subtropics, with home cultivation of Kosmea or winter stay in greenhouses. In other cases, cultivation through seedlings is recommended, with the sowing of seeds every year.

    Chocolate Cosmey is called for its sweet smell with a touch of cocoa. The color of the flowers led to another name for the variety - blood red. The velvet petals have a deep, dark color, which is black in places. The height of an adult plant is 40–150 cm. The diameter of the flowers rarely exceeds 4 cm.


    Care of young cosmos

    Cosmos plants pleasantly surprise with drought resistance, but at a young age, at the very beginning of growth, it is necessary for a plant to maintain a stable soil moisture. At a time when the kosmeya is building up its vegetative mass and until the beginning of flowering in a drought, it is better to water the plants. During the flowering period, watering is carried out only during severe droughts and in heat, in order to maintain profuse flowering and extend the duration of the flowering period as a whole.

    When growing cosmos, top dressing is not at all an obligatory care item. They begin to carry out them at the stage of budding, full of mineral fertilizers, repeating several times over the summer. During the growing season, top dressing can cause a build-up of greenery to the detriment of flowering. Excess nitrogen is especially dangerous for space.

    If a tall kosmeya was sown or planted on a windy site, as the bushes grow, it is better to take care of installing supports and a garter. Thanks to the light greenery, an ordinary peg is enough for the plant.

    With the appearance of the first flowers, you need to start regularly removing the wilting flowers. Without such a simple procedure, the flowering of Moscow chamomile will be quite short and not so lush. To collect seeds, selectively leave the largest flowers, while the rest are regularly removed.

    Due to its hardiness and resistance, problems with pests or diseases are rare in this plant. Usually, difficulties with rot arise only in unfavorable autumn, young seedlings or seedlings are not afraid of the disease.
