Gardeners know that in order to stimulate continuous flowering from a plant, wilted flowers must be constantly removed. But if you want to harvest petunia seeds, you will need to wait until they are fully ripe. For this purpose, immediately at the beginning of flowering, outline the lower buds of the petunia, in which the seeds will appear and ripen earlier.
The buds usually form within a week, then flowers open, and after pollination, seeds ripen in a month. Thus, it can take about two months from the beginning of the formation of buds to the moment of collecting the seed material - therefore it is better to choose the buds that form earlier than the others.
Did you know, what do petunia seeds look like? In a box formed in place of a wilted flower, there are about a hundred dark brown or yellowish seeds. They are very small - only half a millimeter in diameter, it is not easy to work with such seed material. You can remove the yellowed box with the seeds and put it in storage in a dry place, but when harvesting seeds in winter, it is better to shake them out of the box.
Dose seeds at room temperature for another three to four months
Having figured out the question of how to collect petunia seeds, spread the dried seed material in paper envelopes and sign the varieties so that you do not get confused later. Dose seeds at room temperature for another three to four months. In general, petunia seeds can be stored in a dry place without losing germination for up to four years.

In other areas, at best, plants will grow by the end of summer. Provided that unpredictable frosts do not hurt. Self-grown seedlings are the guarantor of plant protection from diseases. Just in this article, we will consider some of the nuances to help cope with the difficulties in the process of growing seedlings from seeds. This is even an unpretentious flower, but at the first stages it will be difficult without certain knowledge.
Cutting petunias for the winter
In order to prepare cuttings, the varieties of petunias you like can be cut off or the tops of the lashes, with about 4-6 leaves, cut off the number of cuttings you need. You can cut the whole lash and cut the number of cuttings you need at home.
Cuttings can be rooted in disposable, plastic, 100-gram cups. Use transparent cups so that you can see when the cuttings have roots.
For rooting, you don't need a lot of soil; you can pour a little more than half into the cups. Priming should be very loose and breathable. You can add coconut fiber, perlite, vermiculite to the soil composition - the soil will be loose and will be able to keep moisture.
Sprinkle the soil in the cups with plenty of water and prepare the cuttings for rooting. On the cuttings, remove all unblown buds, flowers, seed boxes, old, diseased, yellowed leaves.
Next, with a sharp knife, cut the petunia twigs into cuttings with 4-6 leaves... Before planting, remember where the top is at the cutting, and where is the bottom, for proper planting in the ground.
Next, we plant the cuttings in cups with soil, just stick the lower end into the soil. After planting, compact the soil around the cutting. To avoid overflows, do not forget to make drainage holes in the bottom of the cups.
Put the cups with cuttings in transparent plastic bags without holes and tie tightly. Thus, it will be supported desired humidityso that plants without roots do not die.
Put the cuttings under the lamp, they will take root for 1-2 weeks, it all depends on the variety.
What do petunia seeds look like?
After the cessation of flowering, a box is formed in the place of the flower... The box contains seeds. In petunias, they can have a brown or yellow tint. They may also be black, depending on the variety. The seeds of petunias are tiny in size. Because of this, it is easier to buy professional seeds. But if you have petunia growing on your site, then you need to know how to collect petunia seeds at home on your own.
When to plant petunias for seedlings
When growing petunia, they are guided by the fact that 10-12 weeks pass from sowing seeds to planting in the ground. In the southern regions, where the threat of frost passes in April, seeds are sown in the month of February. In Siberia, the Urals, northern regions - they are sown not earlier than March.
If you own a polycarbonate greenhouse, seeds can be sown in April. Seedlings grow no worse than at home. Moreover, grown in a greenhouse, it is more hardened, does not stretch. And planted in open ground, petunia grows well and blooms until autumn frosts.
When growing seedlings on a windowsill, sowing is carried out when the daylight hours become longer, since when growing plants need good lighting and optimal temperature, otherwise the seedlings can stretch out, get sick, and flowering will be delayed in time.
How to care for petunia in flower beds and flowerpots
The difference lies in the amount of soil in which the flowers grow. If in large flower beds or in flower beds you will have to water the flowers as needed and depending on the weather conditions, then in cramped pots and boxes the moisture will evaporate too quickly - you will have to water the petunia often.
Sometimes it is necessary to water the flowers at least twice a day. It is better to do this in the early morning and evening, when the sun no longer bakes.
Petunia care is not only about watering, flowers need other "procedures":
- It is necessary to continue pinching stems and shoots on bush varieties throughout the flowering period. Only in this way the bushes will be neat and well-groomed.
- Withered flowers should be picked weekly. Leave a few inflorescences if you need to collect seeds for the next season.
- If you fertilize the flowers at least once every two weeks, the inflorescences will be larger and brighter, the flowering time of petunias will last.
- Petunia belongs to the plants of the nightshade family, which means that the same diseases that affect potatoes and tomatoes are dangerous for it. You can protect flowers from the "black leg" with the preparations "Oxadixil", "Metalaxil" or "Mancozeb". This disease appears due to excessive moisture. The same problem leads to the infection of petunias with late blight. For this ailment, flowers must be treated with preparations containing copper. Otherwise, the roots of the plants will begin to rot, and the bushes will disappear. Small grayish spots on the leaves and flowers may turn out to be gray rot - another fungal disease of ornamental plants. It must be fought with the help of such means as "Spor", "Maxim" or "Integral".
- To prevent infestation of flowers, it is enough to maintain a normal level of humidity - the ground between the bushes should not be too dry or too wet.
- In the middle of summer, as a rule, petunia begins to degenerate - there are fewer inflorescences and leaves on the bushes. To renew the plants, their stems are pruned. On bush plants, you need to leave 10-15 cm, and ampelous ones are shortened exactly by half.
To preserve the "breed" and prolong the life of the valuable petunia variety, you can try propagation by cuttings. Cuttings are cut from the bushes of parent plants and placed in a cool place for the winter. In the spring, the cuttings are placed in water until the roots appear, then they are grown as ordinary seedlings - in pots or boxes.
That's all the recommendations on how to properly grow petunia in your garden.
