Petunia is a popular herb that is purchased by flower lovers to decorate a veranda, balcony, or loggia. But not everyone knows that you can save money and collect the seeds of this perennial on your own. The collected planting material will be useful for planting flowers next year. The main thing is to know when to collect petunia seeds and how.

Spring is the beginning of the petunias flowering period. They delight with their palette of colors throughout the summer. The decorative qualities of these flowers have long been appreciated by many flower growers and simply nature lovers, summer residents. They try to use plants to create coziness in their area, to decorate and create a festive mood. Taking care of petunias is not difficult.

In order for the bright different shades of flowers to smell fragrant every year on your site, it is necessary to collect petunia seeds annually. And everyone can grow new plants from seeds. To do this, at a certain time (after the end of the flowering of petunias), it is necessary to collect the seedlings, and plant them in the ground in early spring.

In the petunia family, there are a large number of different species and varieties. They are all united by the funnel-shaped flower shape. The palette of colors and various shades pleasantly surprises and delights - white, pink, red, turquoise, blue, violet and blue flowers. There are also various forms of petunias - double and semi-double.

All about petunia seedlings


This herbaceous culture has very small seedlings. One seed is about half a millimeter in diameter. The seeds are light brown or dark brown in color and are formed in small capsules - fruits, each of which contains about one hundred seedlings. A fairly large amount of planting material can be collected from several petunias for the next season. And if you consider that in specialized flower shops, petunia seeds are sold by the piece, then there is a real incentive for self-collecting seed material.

Collection time

Ripening of seeds of petunias continues for eighty - ninety days after the beginning of active flowering of these herbaceous crops. As soon as the seed pods begin to take on a yellow or light brown hue, you can start collecting them. Bolls suitable for collecting seeds - the fruits are located in the lower part of the plant stem. They ripen and wither before everyone else. To make it easier to find such buds, you need to make some notes when the petunias are just starting to bloom.

The process of obtaining and collecting seedlings

If you expect the full ripening of the buds - the fruits on the flowers, then the flowering period of petunias will be much shorter. Experienced flower growers recommend that the previously marked buds with seed bolls be torn off the stems, and then new buds will continue to form on the culture, flowering will continue until the end of summer. Next, you need to remove the boxes from the buds and, if the seeds are not yet ripe, put them in a well-lit place, after placing them in a bag of thin transparent fabric or a tea bag. This is necessary so that after full ripening the seedlings do not fall out of the bolls. The seeds will remain intact and safe, being in such a protective "container".

Drying of seed material after opening the bolls should continue for at least two more days in a warm place. Seeds that are carefully dried can retain their quality characteristics until the next season. It is recommended to store them in small paper bags in a dry place at room temperature. You need to pack the seeds by varieties and immediately sign the packages, so that it is convenient to plant them later.

Petunia is a flower crop with high seed germination. Under proper storage conditions, planting material can retain its properties for 3-4 years.

Note to flower growers!

When growing petunias, it is necessary to take into account the characteristics of individual species and varieties. Most of them do not require complex care and are easily propagated by seeds, but the double-shaped flowers are special. For their propagation, it is recommended to use the cuttings method. This will save you from unexpected results and surprises that are possible with seed reproduction.

Spring planting of seedlings

Petunia seeds for growing seedlings are sown at home in late March - early April. You can sow seeds directly into open ground, but they do it much later (around the end of May), when the soil warms up well and warm weather sets in.

A drainage layer must be poured into the planting containers, and then light and loose soil. The seeds are sown evenly over the surface of the soil, pressing slightly, and then sprinkled with a two-millimeter layer of soil. The soil should be slightly moist all the time. The boxes must be covered with glass or foil to create a greenhouse environment. The temperature of the content is from 20 to 25 degrees Celsius.

Young seedlings require long-term bright lighting. From time to time (about 1 time per day), the landing boxes need to be turned to the light source in different directions. In case of a lack of light, artificial supplementary lighting is recommended.

Watering is carried out moderately, waterlogging of the soil should not be allowed. Various dressings and fertilizers have a beneficial effect on petunias. Transplanting seedlings to open beds is carried out at the end of May.

Petunias Grandiflora: growing from seeds (photo)

Petunia is one of the most popular flowering horticultural crops. Flowerbeds or wooden tubs with lush bouquets of bright "gramophones" will be an excellent decoration of the personal plot, and pots with luxurious ampelous plants will perfectly complement the interior of the balcony, veranda, terrace. Among the many varieties of this culture, Petunia Grandiflora (Petunia Grandiflora) occupy a special place. Despite the fact that gardeners speak of them as very picky individuals, it is quite possible to grow large-flowered varieties on your site or in a mini-garden on the windowsill. Next, let's talk about how Petunia Grandiflora is grown from seeds. The photos posted in the article demonstrate its amazing beauty.

What does it mean: a short description

The plant is remembered for its extraordinary peduncles and unusual color options. The shoots grow in length up to 1.2 m. In rare cases, the shoot can be up to 30 cm in length. The main feature is the stems creeping along the ground. The foliage is soft, slightly pubescent on top. Leaves also increase in size with age.

Flowers form in each bosom. One bosom - one flower. They look like bells in appearance. The colors are very diverse - from white with a milky tint to exotic.

Popular varieties: names, descriptions and photos

Petunia has several dozen varieties. They all differ in appearance, color, growing conditions. There are three types of petunias:

  1. Cascading.
  2. Ampelny.
  3. Shrub.

Popular varieties of ampelous petunias are as follows.

Easy wave

Scourges reach lengths of up to one meter.

Due to the abundance of flowers, foliage is practically invisible. By providing active additional lighting, you can enjoy flowering until the coldest days.


The group is resistant to adverse weather conditions. Differs in fast growth of shoots... It is characterized by a variety of colors.

The Snow Queen

In the flowering phase, the plant resembles a snow-white waterfall of flowers with a diameter of 7-10 cm. Suitable for growing in the open field, apartment, pots. Shoots grow up to 80 cm in length.

Opera supreme

Available in white, pink, coral and blue shades. The stems reach 1 m in length. They are unpretentious to the conditions of detention... Suitable for open areas and hanging pots.


Shoots up to 1 m long. The flowers are pink, up to 5 cm in diameter. They need a lot of sunlight and heat. They are used to decorate loggias and balconies.

Difference from cascade and bush varieties

Ampel and cascade petunias have a lot in common, however, with a detailed comparison, you can see that these varieties are different, and here is their difference:

  1. Shoots of different lengths. The stems are pinched only in cascading species.
  2. Shoots of varying strength. The cascading group of flowers is characterized by juicy and flexible stems.
  3. Trailing pots are designed to a greater extent for hanging planters, and cascading ones cover the soil well.
  4. Cascading petunia is characterized by buds of the same color and size throughout the plant. Ampel varieties on one plant can have flowers of different sizes and colors.

Ampel varieties begin to release side shoots. The appearance of the seedlings resembles a bush without a main stem.

Shrub varieties start growing from the main shoot. Lateral stems begin to form after pinching or the appearance of the first flowers.

What you need to know about sowing petunias?

First of all, pay attention to the choice of seeds: not only the quality of the planting material is important, but also the variety of petunias. Many old varieties do not tolerate bad weather, losing their attractiveness, but strong winds, frosts and rains are not terrible for new hybrids. Now you can safely choose even terry petunias for decorating flower beds, which were previously considered the most capricious. But at the same time, keep in mind that varieties belonging to the Grandiflora group are distinguished by the least resistance to adverse weather conditions. Petunia varieties of multiflora and floribunda groups tolerate bad weather best.

The first half of March is the best time to sow petunias

Reproduction of the favorite terry, ampel and large-flowered varieties of petunias is best carried out by cuttings, since some varieties do not give seeds at all, while others, when propagated by seeds, lose their characteristic color and terry. In addition, petunias grown from cuttings begin to bloom two weeks earlier than those grown from seeds.

Petunia care video

Nevertheless, the overwhelming majority of domestic flower growers prefer to grow seedlings from purchased or self-collected seeds. The seedless method is also practiced, but it is not suitable for the Russian climate, since when sowing petunia seeds directly into the open ground, flowering will have to wait for a very long time. While with the help of seedlings, you can decorate your site with already blooming petunias at the very beginning of summer.

To get good seedlings of petunias, follow these rules:

  • the first half of March is the most appropriate time to sow petunias, then by the beginning of June the plants will fully grow stronger and begin to bloom
  • the soil for planting needs neutral, fertile, loose, capable of letting in excess water when watering
  • mineral fertilizer and humus can be added to the soil, but the introduction of fresh manure is excluded
  • at the bottom of containers intended for seedlings, be sure to lay a layer of expanded clay or other drainage
  • it is recommended to sift the prepared soil mixture and pour the larger screenings over the drainage, and use the smaller one as the top layer
  • compact the soil a little
  • it is more convenient to mix the smallest seeds with sand, then the sowing of petunias will be more even
  • after distributing the seeds over the soil surface, spray them with warm water from a spray bottle and sprinkle them on top with a millimeter layer of earth (you don't need to cover the seeds with earth at all)

  • cover the container with a transparent film or glass and leave for five days to germinate at a temperature of about +22 degrees (wipe the condensation from the film from time to time)
  • sprinkle small shoots that have appeared with water twice a day and slightly open the film for a short time to air the seedlings
  • once spray the seedlings of petunia with nitrogen-potassium fertilizers and, if necessary, a growth stimulator
  • provide the seedlings with sufficient lighting, otherwise they can stretch out in a day from lack of light
  • with the appearance of the first leaflet, the film is removed from the container.

As soon as a second true leaf appears on the seedlings, they should be dived into separate cups, deepening into the soil mixture to the leaves, and continue to look after seedlings. When the number of leaves reaches five, the top of the seedlings is cut off for greater bushiness of the plant.

Growing seedlings of petunias

Collecting flower seeds

Among the variety of flowers, they can be distinguished into separate groups: with scattering of flowers as they ripen, with a uniform and uneven ripening period, and seeds located in baskets.

Plants scattering seeds

Sometimes spreading is done over long distances. Collecting seeds from such flowers is quite difficult. It is necessary to catch the moment when the fruit is ripe and you need to have time to pick it to get seeds. In addition, the spread of seeds by the plant itself clogs the soil, which leads to unplanned sprouting. However, most gardeners have found their own ways of obtaining seeds from such playful plants. Consider the tricks of collecting flower seeds for specific species.

Sweet peas, lupine has mature seeds when the bean turns yellow and dries up a little. Ripening is uneven, the collection is carried out repeatedly, carefully, as the bean can crack and discard the contents right in the hands.

Ripe unopened fruit geraniums should be cut as long as possible. With unripe fruits, they do this: cut off the sharp end of the fruit, the flaps will now not curl and the catapult will not work, and a gauze bag can be put on the fetus.

Boxes balsam must be harvested when fully ripe. It is easy to determine, if you rub the shutters of the fetus, they will begin to open. The collection is carried out carefully, the seeds can spill out right during the collection. Remember that unripe fruits that are plucked will not ripen and the seeds will rot.

Seeds phlox drummond collected when the lower boxes begin to open, and the upper ones are torn off during the period of wax ripeness, in order to then ripen them in a dry room, wrapped with cloth or paper.

Seeds cleoma, escholzia, viola (pansies) should be collected at wax ripeness, wrapped in a cloth and ripened. It is better to collect it in the morning, when the air is not yet so dry. The collection of fruits is carried out in several stages as the fruits ripen.

Plants form a fruit basket

In this case, the seed baskets are harvested when they turn light.

Gelichrisium, aster, rodanthus, arktotis, gatsania

In these flowers, when the fruit ripens, the basket closes and a fluff appears in the middle. In a rainy autumn, it is worth collecting the baskets in advance immediately after the inflorescence wilts and putting them on ripening. It happens that late varieties did not have time to form bolls. In this case, you can dig up the flower, place it in a pot and grow it in any cool room, for example, on a balcony, veranda. It is useful to learn how to grow asters.

The seeds are harvested when the basket inflorescence turns brown and begins to dry out.

marigold seeds

Cloves, marigolds

The signal for collecting flower seeds is the dried and yellowed wrapper of the basket, and the petals dry well. In rainy weather, the baskets will rot quickly, so you need to collect them as soon as the petals begin to fade. The seeds will ripen indoors.

Calendula, cosmeya, succession

The baskets are not harvested green, as their seeds will not ripen.The good quality of the seeds is indicated by their color ranging from yellow-brown to black. Surprisingly, the most beautiful, bright and double calendula flowers grow from thin, strongly curved seeds.

The ripening of the seeds is signaled by a dried fruit, in which the scales begin to diverge. In unfavorable weather conditions, the inflorescence can be collected immature and placed in a dry room.

  • In Central Russia and the Volga region - the first and second ten days of February,
  • In Siberia and the Ural region - the first decade of March,
  • Southern regions of Russia and the Black Earth Region - the first decade of February.

Depending on the variety, the time for planting petunia seeds also differs:

  1. Ampel varieties are sown for seedlings in the first decade of February,
  2. Dwarf in the second decade of February - the first decade of March.
  3. Bush petunia - in the 1st and 2nd decade of March.

How to properly grow petunia seedlings from seeds at home?

To begin with, you should choose the right seeds for planting and high-quality soil.

What seeds are best for growing petunia seedlings?

In appearance, petunia seeds are more like small poppy seeds, and sometimes they can be easily confused with dust particles.

Seeds are of the following types:

  • natural
  • granular.

For planting seedlings, it is optimal to take seeds in the form of granules, because each grain, in this case, is “framed” in a special protective “cape” composed of various useful elements that increase the rate of seed ripening, feeding it, accelerating growth in the soil surface and protecting the grain from any types of diseases.

The choice of soil for seedlings of petunias

Sowing petunia seeds is best in a mixture of soil from peat, turf, humus and sand in a 1: 1 ratio.

Or just buy ready-made seedling soil in the store. The main thing is that the soil is light, and it is desirable that perlite be added to its composition.

How to sow petunia seeds for seedlings?

It is best to start sowing with the onset of March, according to the lunar calendar.

  • You will need a plastic seedling container with a transparent lid or any other suitable container and glass filled with suitable soil. It must first be spilled with a solution of potassium permanganate and well moistened with water from a spray bottle.
  • Wait for the water to be absorbed and now sow the seeds superficially, without sprinkling them with earth (THIS IS VERY IMPORTANT. These seeds need light to germinate.) Then cover them with a transparent lid or glass plate so that natural moisture does not escape from the seeds.
  • Now put the container with petunia seeds in a well-lit place with an air temperature of about 25 ° C, using regular spraying, maintain the soil moisture level, ventilate and remove accumulated condensation.
  • Under good conditions, seedlings should appear within about 10 days after sowing. After the seedlings appear, start gradually hardening the plants: lower the temperature and ventilate periodically.
  • Further, after about 30 days, you can make a pick, i.e. carefully transfer the young seedlings from the small box into separate containers.

How to dive petunia seedlings?

The technique for picking a petunia is as follows:

  1. Prepare containers for transplanting seedlings - these can be plastic cups or pots. Fill them with fresh, loose, fertile soil, make a well, and pour over the mixture.
  2. Using a wooden stick, slightly loosen the soil in the container with seedlings, gently pick up the shoot, and transfer it to a new glass, sprinkle with earth, compact and water.
  3. Remember that petunias have a branched root system, so they are immediately transplanted into a sufficiently large container with the expectation that the plants will grow in it for 3 months.
  4. 2 weeks after the pick, when the seedlings get stronger, keep the plants at a temperature of 15 ° C at night and 18-10 ° C during the day.
  5. Water the plants sparingly, but often: petunia does not like either drought or excessive moisture.
  6. The first feeding of petunias must be carried out 14 days after the pick. Dilute a tablespoon of urea with a little Agricola 7.

When to plant petunia seedlings outdoors?

Flowers can be transplanted into open ground when warm weather sets in, as a rule, this is mid-May.

Until that time, you can leave the seedlings on the balcony, but at an air temperature of at least 16 ° C.
