Sowing flowers in April for seedlings: timing, care, when to plant in open ground

Garden plants

In April, in areas with a warm climate, it is already possible to sow annual flowers in open ground, but where the spring is late, and the summer is short and cool, it is better to use the seedling method of growing flowers. There are no strict terms for sowing seeds of this or that species, because the duration of the growing season of a crop depends on many conditions: local climate, weather, quality of seeds and soil. Based on this, you yourself will have to decide when exactly to sow flower seeds for seedlings and at what time then to plant seedlings in the ground, but there is a certain list of plants that are most often sown for seedlings in April.

What flowers are sown for seedlings in April

At the very beginning of the month, hurry up to sow what you have not yet or forgotten to sow in March - seedlings in April of alyssum annual, viola, godetia, sweet peas, as well as seedlings of petunia, scented tobacco, iberis and salvia from those gardeners who sowed the seeds of these plants at the end of February or in March, has already risen and developed well. At the beginning of April it is not too late to sow the seeds of seedlings of these flowers, in order to plant the seedlings in open ground at the end of May or the beginning of June.

In addition to the above crops, it is possible to plant seeds in April of such flowers as scabiosa, fragrant mignonette, osteosperum, obrieta, xerantenum, daisy, Suvorov limonium, morning glory, calendula, decorative cabbage, delphinium, pompom dahlia, helipterum, venidium, vautochil annual, amaranth, ageratum and marigolds. We will tell you more about sowing some of these flowers.

Aster annual

She is charming, and her real name is Chinese Callistephus. There are about 4000 varieties of callistephus, which are divided into 40 groups: peony, pompom, needle, with small and large inflorescences, purple, red, pink, white - they are very beautiful and stand for a long time in the cut. Asters bloom from late June to October.

Growing seedlings of annual asters begins in late March or early April. The soil for seedlings should be light and fertile: mix two parts of turf and one part of peat, put the soil in a box and spill it with a fungicide solution from the "black leg". Powder the aster seeds with a fungicide too, sow them on the surface of the soil, press against it with a spoon and pour the crops with a light pink solution of potassium permanganate through a spray bottle, then cover with foil, glass or paper.

Seedlings should appear on the third or fifth day, and then the cover is removed, and the crops are moved as close to the light as possible so that the seedlings do not stretch, but the temperature must be lowered - if you have a veranda or a place on a glazed balcony, it would be better to move the boxes there. Watering must be careful: just water each seedling with a teaspoon.

When one or two true leaves appear, the seedlings dive at a distance of 5-7 cm from each other into boxes or cassettes for larger seedlings. Asters, unlike other colors, love dives. Planting seedlings in open ground is carried out in the second half of May. One-year-old aster seedlings are not afraid of light frosts.


These flowers - marigolds, or tagetes - reproduce well by sowing in the ground, but if you give yourself the trouble to first grow seedlings from seeds, they will bloom two to three weeks earlier, and their flowering will be more magnificent and longer. In addition, you can not plant some of the seedlings in open ground, but leave them in pots and decorate an apartment, balcony, loggia or terrace with them. Marigold seeds are sown into a moist substrate of this composition: one part of turf, humus and peat and half of sand.

In order to avoid the disease of seedlings with a black leg, a drainage layer of expanded clay should be placed under the ground in the seedling boxes, and the substrate should be spilled with a solution of potassium permanganate or fungicide - Maxim, Fitosporin or Vitaros. Another way to sanitize sowing soil is to steam it in a double boiler for an hour. Spread the seeds along the grooves with tweezers, then sprinkle with a layer of soil 1 cm thick, carefully water the crops and cover with glass or transparent film to create a greenhouse for seedlings, which must be kept in a bright place at a temperature of 15-20 ºC.

Marigold seeds germinate in such conditions in a week and even earlier. If the indoor temperature is below 15 ºC, the seeds germinate poorly and for a long time, and if it is above 25 ºC, they may not germinate at all. As soon as the first shoots appear, the crops are aired daily, and the condensate is removed from the film or glass. When seed germination becomes massive, the cover is removed. Water the substrate only after it is completely dry. Do not leave spilled water in the pan. Once every two weeks, feed the seedlings with a solution of a complex fertilizer such as Fertiki Lux, Solvent or Agricola in a weak concentration.

Tagetes dive in the development phase of 2-3 true leaves, shortening too long roots in the process and deepening the seedlings almost by cotyledonous leaves, into cassettes for seedlings with the same soil composition as in the primary sowing, but with the addition of a substrate for every five liters tablespoons of complete mineral fertilizer and half a glass of wood ash. After picking, the seedlings are watered and, if the earth settles strongly, soil is added to the cassettes.


This plant conquers with the majesty of its inflorescences, endurance and unpretentiousness. Many in winter are happy to keep dry bouquets of amaranth in the house. In our climate, of more than 900 plant species, only 15 are cultivated, of which the most common are paniculate, tailed, dark and tricolor amaranths.

Amaranth seeds are sown on a moist, loose substrate, sprinkled on top with a centimeter-thick layer of peat with sand, moistened with a spray bottle, covered with glass and kept at a temperature of 22 ºC - if these conditions are met, seedlings appear in a week, or even earlier. As soon as they appear, immediately move the crops as close to the light as possible.

In the phase of development of the first true leaf, the seedlings are thinned out, leaving only the strongest of them, and at the stage of development of three leaves, the seedlings dive into separate containers with a diameter of 12 cm.

Delphinium perennial

To create a beautiful flower bed, you sometimes just need to successfully place one delphinium bush on it - blue, pink, white or purple inflorescences up to 2 m high will surely cause admiring and even envious glances of your neighbors, especially since the delphinium blooms twice a season.

The depth of the container for delphinium seedlings should be at least 10 cm, and the substrate for a plant that is demanding on the soil should consist of peat, humus and sand in equal parts. Seeds are sown on the surface of the substrate, and sprinkled on top with a layer of sand 3-5 mm thick. Since the seeds of the delphinium need stratification, a layer of snow is placed on top of the crops (you can from the refrigerator) and keep them at a temperature of 4-7 ºC until shoots appear. This so-called accelerated stratification increases the percentage of seed germination and hardens future seedlings.

You can, of course, not stratify the seeds, and then they will sprout a week later.

Water thin fragile seedlings separately with a teaspoon, so as not to accidentally damage or wash them out of the substrate. The soil should be slightly damp at all times. At the stage of development in seedlings of 2 leaves, seedlings dive at a distance of 6-7 cm from each other.


These lovely flowers are incredibly popular with gardeners. Sow them in separate pots on moist loose soil without embedding. The pots are moved to seedling greenhouses or covered with glass, placed as close to the light as possible and kept at 20-24 ºC. Seedlings will appear in two to three weeks, and then the glass can be removed, and the temperature of the content can be lowered to 15 ºC so that the growing seedlings do not stretch too much. For this, you may have to arrange additional lighting for seedlings, the daylight hours for which should be at least 12 hours.

Water the crops as the soil dries. Daisies don't dive.


This cornflower-like flower is as modest as it is beautiful and versatile - it is appropriate both as a solo plant and as an accent in the background of a flower bed. Another advantage is its long flowering from June to October.

In mid-April, we sow scabiosa seedlings in a universal soil mixture, cover the container with glass and keep it at a temperature of at least 15 ºC, airing it daily for an hour, moistening the soil and removing condensation from the glass. Seedlings usually appear in 7-10 days, and then the cover is removed. In the phase of development of 2 leaves, seedlings dive into boxes at a distance of 5 cm from each other or into separate cups.

Annual dahlias

Dahlia flowers are easy to grow, easy to care for, they bloom for a long time - from July to frost. It is hard not to notice them in the garden, these bushes up to one and a half meters high with flowers of red, yellow, orange, purple, red, white and pink shades, reaching a diameter of 10 cm.

Dahlia seeds are sown in seedling boxes in a wet mixture of sand, peat and perlite, sprinkled on top with a thin layer of the same soil, covered with glass and placed in the light, maintaining the temperature within 25-27 ºC. Seeds germinate within a week. After the emergence of seedlings, the glass is removed, the seedlings are watered by spraying. When the third true leaf appears, the seedlings dive into separate cups filled with disinfected soil of the following composition: 50% sod land and 25% peat and sand each.

To sterilize the substrate, a dark pink solution of potassium permanganate is heated to 70 ºC and the soil is spilled with it. A week after the pick, it's time to make the first top dressing.


In translation, the name of the flower means "a plant that collects water", therefore in Russian aquilegia is called "catchment". Aquilegia has bright white-blue, blue, white or pink flowers of a fancy shape and delicate lacy leaves. In the middle lane, about 30 species of aquilegia are cultivated.

Before sowing, the seeds are subjected to scarification - the integrity of their shell is mechanically violated, for which it is lightly rubbed between two sheets of fine sandpaper. Seeds of aquilegia are sown in early April in peat tablets for seedlings or in separate cups filled with moist soil, consisting in equal parts of leaf humus, sand and sod land. From above, the seeds are sprinkled with a layer of soil 3 mm thick through a fine sieve, which is subsequently kept in a slightly damp state all the time. The crops are covered with paper.

For successful germination of seeds, it is necessary to maintain the temperature in the room at least 18 ºC, then the seedlings will appear in a week or two.

The emerging seedlings need moistened soil, but excess moisture can lead to fungal diseases. At the stage of development of two or three true leaves, seedlings dive into larger containers or are planted in open ground, if the weather permits.


With the help of the Mexican ageratum, or long-flowered, gardeners create borders and ridges that serve as a garden decoration before frost. Ageratum flowers are collected in fluffy baskets of white, pink, burgundy or purple. Plant seeds are sown in boxes on top of a moistened light nutrient substrate, without deepening them, after which the boxes are covered to create a greenhouse effect with film or glass. Keep crops warm, preventing the soil from drying out.

As soon as the first seedlings appear after a week or two, the glass is removed, the temperature in the room is slightly lowered, and after three weeks the seedlings dive in separate pots. It is possible that rapidly growing seedlings will need another transplant into a larger container, since this tropical plant can be planted in open ground only when warm weather is finally established - in late May or early June.


This is still a rare and exotic guest in the gardens of the middle zone. It is grown not only to decorate flower beds: its catchy inflorescences stand well in cut, and dwarf Venidium hybrids are grown in containers on balconies, in garden pots and on window boxes.

It is better to sow large seeds in 2-3 pieces in pots or cups with drainage holes, filled with light nutrient soil of a neutral reaction, embedding seeds into the soil to a depth of 5 mm. After planting, the pots are placed in a common tray, covered with glass or foil, placed closer to the light and kept at a temperature of 20-24 ºC. As soon as after a week and a half the seeds germinate, the coating is removed and in the future they treat the watering of the soil with great care, since the Venidium seedlings are sick from excess moisture.

Seedlings develop quickly, it is not difficult to dive them, and pinching the tops of the seedlings stimulates the formation of dense bushes.

Care for seedlings of flowers in April

Watering seedlings

Until the seeds germinate, there is no need to water the soil, and the emerging seedlings are equally harmful as a lack and an excess of moisture. Prolonged waterlogging is especially dangerous - from it the leaves of the seedlings turn yellow, the stems become brittle, and the roots rot, therefore, the seedlings are watered regularly, but in moderation, be sure to drain the excess water from the pan. Water for irrigation must be filtered or settled during the day, the temperature of the irrigation water cannot be lower than the temperature in the room where the seedlings are grown. To moisten the soil, a spray gun is most often used so that the jet does not erode the soil and does not expose the roots of the seedlings.


The seeds germinate in the warmth, for this they need a temperature in the range of 18-22 ºC, but as soon as shoots appear, the temperature is lowered to 12-18 ºC so that the flower seedlings do not stretch too much. Seedlings at home are not always kept with optimal temperatures and lighting, since it is difficult to maintain the difference between day and night temperatures in an ordinary apartment. It is better to grow seedlings of flowers that are especially demanding to this condition not in an apartment, but in a greenhouse or on a glazed balcony.

Seedling picking

Seedlings dive during the period of full development of one or two true leaves. Usually, seedlings are transplanted from a common box into separate pots in a soil mixture of the same composition as in the initial sowing. Try to remove the seedlings for transplanting together with an earthen clod, and to make it easier to do this, water the soil well in a box with seedlings before the procedure. The seedlings are deepened when picking at the cotyledonous leaves, however, without covering them with earth. The long roots of the seedlings are shortened by a third of the length during transplantation. After picking, cover the seedlings from bright light for several days.

There are types of flowers that do not tolerate picking very well, so they are not sown in a common container, but in a separate dish - pots, cups or peat tablets for seedlings.

Top dressing

The first time the seedlings are fed a week after the dive, when they adapt to a new place. The second feeding can be done two weeks after the first. The third, if necessary, is carried out before planting seedlings in open ground.Weak seedlings of plants need, first of all, nitrogen, which contains urea and saltpeter, however, when applying fertilizing, observe moderation, do not overfeed the seedlings with nitrates, because in conditions of high humidity and temperature, seedlings that have received an excess of nitrogen will have problems with rooting in open ground.

The second and third feeding can be complete, that is, in addition to nitrogen, they contain phosphorus and potassium. Choose fertilizers at your discretion: it can be ready-made preparations, such as Uniflor micro, Solution, Nitrofoska, Kristallin, or water-soluble Kemira, or maybe a weak mullein solution. If, despite all your efforts, the seedlings still grow poorly, try feeding them through the leaves with growth stimulants, be sure to observe moderation in dosages.

When to plant seedlings in open ground

Ten days before planting seedlings in open ground, they begin to harden. If you keep the seedlings on the windowsill, open the window for a while so that the plants gradually get used to the fresh air. Every day, the time of the airing session is increased, but at first the occurrence of drafts should be prevented - flower seedlings grown in home or greenhouse conditions are very afraid of them.

It is best, of course, to take the seedlings out to an unheated veranda or a glazed balcony and keep them there until planting on a flower bed, opening a window during the day and gradually accustoming the seedlings to the temperature outside, to the bright sun and breeze. Seedlings ready for planting in the ground should be painlessly carried out on a balcony with an open window for a whole day, provided that the outside temperature is not lower than 12 ºC.

When growing seedlings in a greenhouse, for the first time, in order for the seedlings to get hardened, the film is briefly opened, increasing the duration of the procedure daily, and then completely removed, if weather conditions permit.

When to plant aster seedlings in 2021 + sowing dates on favorable days

For many people, the autumn season is associated with lush flower beds in the garden and flowering perennials. Traditionally, gardeners grow chrysanthemums, asters, gladioli, tulips, lilies and more.

This allows you to enjoy blooming petunia and eustoma in your garden or in flower pots in season.

Unpretentious asters stand out from this list: they have many varieties, both dwarf and tall, but almost all of them differ in their bright and fluffy flowers.

The optimal timing of sowing gelichrizum for seedlings in 2021

Sowing the seeds of this flower culture should be about 1.5-2 months before planting in open ground. During this period, the seedlings will have time to grow, get stronger, build up the root system and the aboveground part.

The approximate dates for sowing gelichrizum for seedlings fall on the month of March. But again, you need to take into account the climatic features:

  • in the middle lane (Moscow region) - planting a crop is optimal in the second half of March (planting in open ground - in the second half of May)
  • in Siberia, in the Urals - sow seeds in late March or early April (plant in the garden - in late May or early June)
  • in the South (Krasnodar Territory) - you can plant seeds already at the end of February, at the beginning of March (planting seedlings at the dacha - in mid-April).

Flower sowing lunar calendar for 2020

If you want to know when there will be favorable days according to the lunar calendar for sowing flowers in 2020, you should look at the table. Monthly and daily data will come in handy.

Summer residents who want to decorate a flower bed with petunia, lobelia, salvia in May will have to try. Plants need extra lighting. Therefore, you need to purchase additional lighting lamps.

The first spring month will add hassle to the summer resident. At this time, it is worth sowing the following plants: cloves, lupine, sweet peas, balsam, lobularia.

By this time, the soil is already well warmed up. You can transplant perennials, divide the rhizomes of irises, peonies, roses, Iberis, carnations.

A flower garden in June needs high-quality watering. Drought can be detrimental to plants. Do not use cold water for irrigation. Before the procedure, she needs to be allowed to warm up. It is best to water in the morning or evening when there is no sun.

Weeds must be controlled in a timely manner. They prevent flowers from developing normally and thicken crops. As a result, the flowerbed loses its decorative appearance.

Irises bloom in July. You need to have time to transplant and separate them. For this plant it is necessary to dig up, shorten the leaves, cut the roots. In this form, the seedlings should be dried and planted in the soil. They will take root by September.

Particular attention should be paid to roses in July. At this time, they begin to bloom. For flowering to be lush and long, you need to feed.

What should a summer resident do in August? The main work is the transplantation of perennials that have faded in the spring. Irises, peonies, primroses, lilies of the valley, bathing suits are at rest. Therefore, the time has come to dig them up and cut off the ground part.

Annual plants have not yet faded. Therefore, you need to provide proper care for them. The first step is to remove the old boxes.

At the end of the month, it is worth planting crocuses, woodlands, irises, muscari. The flower bed will be transformed next year.

Growing seedlings of garden forget-me-nots from seeds

Growing forget-me-nots from seeds is the most common breeding method for garden forget-me-nots. You can grow forget-me-nots both through seedlings and by a seedless method. At the same time, forget-me-not is mainly grown from seeds. Most often they are grown as a biennial plant. Prepared seeds must be dipped in slightly salted water. The floating planting material must be thrown away, most likely, it will not be able to germinate. The remaining seeds must be dried. Like all biennials, forget-me-not seeds are sown in May-June on seed beds or in bowls with loose fertile soil. Seeds are sown superficially on a compacted, moist, flat soil surface and only slightly sprinkled with light soil or sand. The crops are covered with spunbond, polyethylene or glass, the soil is kept moist by watering gently from a spray bottle or over a non-woven covering material. The first seedlings appear literally after five to six days. After germination, the crops are freed from the shelter.

When two true leaves are formed (usually after 3-4 weeks), the forget-me-nots are pulled or planted in pots (1-3 plants) or on growing beds at a distance of 5-7 cm between the plants. For the bushes to be compact, the cultivation of forget-me-not seedlings is carried out in partial shade. Seedlings are periodically watered, the soil is loosened, weeds are removed. For better tillering, the seedlings are pinched. Forget-me-not is fed with complex mineral soluble fertilizer for seedlings once every two weeks. The fertilizer concentration is gradually increased. In late August - early September, forget-me-nots form a dense rosette of leaves. In this form, they are planted in a permanent place according to the scheme recommended for the variety (15-25 cm between plants) and watered well

Culture transplant

The need to transplant onions can arise for various reasons, for example, in order to free up a site for planting another crop or for other needs. The operation is carried out in early spring, although some gardeners perform it in August or early September. For transplanting, you need to choose a suitable site, prepare the holes, carefully dig out the best plants and transfer them to a new place. Planting culture should be performed at the same level, i.e. without deepening and elevation. When the procedure is completed, it is necessary to moisten the soil.
