Petunia does not tolerate the weather conditions of late autumn and winter in the middle lane. However, if you follow a few simple recommendations, you can extend the life cycle of the plant.

General information about petunias

Petunia is a perennial flower native to the tropics of South America. Gardeners are actively planting about 25 varieties of this plant. Petunia owes its popularity to beautiful large flowers with a velvety surface.

The plant is quite unpretentious, however, it does not survive the winter in nature. Therefore, the main question that worries caring gardeners is how to preserve petunia until spring.

Not everyone takes the time to painstakingly take care of a flower from South America. Some hobbyists prefer to discard faded plants and sow new seeds in the spring. This is an easy way to decorate your summer cottage with velvety flowers.

However, if you certainly want to keep your favorite hybrid, you can use the advice of experienced gardeners and extend the life cycle of a tropical guest.

There are 2 methods of preserving the plant until next year:

  • preservation as a mother plant;
  • preservation of cuttings.

Both techniques involve moving the flower from the street to the room. A flower cannot survive in the cold. Some varieties throw seeds before death, but this method of propagation is effective only in areas with a mild climate.

How to keep petunia as a mother plant until spring

So, in order for an adult petunia bush to survive the cold, it is necessary to move it indoors. The required temperature regime is 10-15 degrees. Lower readings are also allowed, however, the thermometer should not fall below zero.

Another requirement is a sufficient level of illumination. The best option for placing petunias for the winter is glazed balconies, closed verandas, entrances of houses.

You need to transplant the plant before the first frost. The right time is September - early November. The bush is dug up and placed in a pot. When transplanting, dry and damaged branches are cut off. Some gardeners practice cardinal pruning: all shoots are shortened to 10-15 cm.

Also, before placing the petunia in the house, you need to carefully examine the plant for the presence of parasites.

The beginning of autumn is the period of greatest activity of the whitefly, which lays eggs on the lower part of the leaves. If an infected plant enters the room, house flowers will also fall prey to this type of insect.

Spring cuttings of the uterine bush

At the end of February, the mother plant is moved to the brightest place. During this period, watering is increased and top dressing is applied. If the petunia has endured the winter well, then by the beginning of April you can start grafting or transplant the bush to open ground or into balcony containers.

Most gardeners agree that the best flowering is in young plants.

Therefore, the planting of rooted cuttings of the mother bush is more popular.

Cuttings 5-10 cm long are cut from the mother bush. Green, non-lignified stems are needed for grafting. 2-3 leaves are torn off from below to get a bare stem 1-3 cm long. 2-3 leaves remain at the top. If they are large enough, they are cut in half to reduce moisture evaporation.

The bare stem is placed in a loose moist soil (peat and vermiculite), the pot is covered with a jar or plastic glass. The cuttings are aired daily. If everything was done correctly, young shoots will appear in 2 weeks.

This means that the cuttings are rooted and the greenhouse can be removed. Before transplanting to open ground, cuttings are looked after in the same way as seedlings.

During this period, watering, feeding and systematic pinching are needed for more tillering. You can start planting seedlings outside after establishing a positive temperature of at least 10-12 degrees.

Petunia on the windowsill: care features

The windowsill is the most suitable place for the wintering of a flower. This placement allows you to make the most of daylight from the street and provides a comfortable temperature for hibernation. If the window faces the north or west sides, additional lighting is arranged for the plant.

Also the advantage of being on a windowsill is the presence of a battery. If you place containers with water near the petunia, it will evaporate more intensively, providing the necessary level of humidity.

At first, after the "resettlement", petunia can manifest itself in different ways. Sometimes the flower immediately goes into hibernation, and in some cases, on the contrary, unexpectedly for everyone, it starts up new shoots and blooms. In such a situation, you need to ensure that the new stems do not weaken the plant.

The rules for caring for a petunia uterine bush in winter are simple:

  • poor watering 2-3 times a month;
  • lack of fertilizers and dressings;
  • high air humidity;
  • good illumination.

With adequate care, hibernating petunia should only partially turn yellow. If the gardener observes drying or blackening leaves and stems, care should be taken to ensure the required level of humidity and illumination.

Also, the poor condition of petunia can be triggered by powdery mildew or an unreleased whitefly. For the prevention of diseases, the plant must be periodically sprayed with a special composition.

How to cut petunia in autumn

Storing petunias as a mother bush requires high humidity and low temperatures. Such conditions are rather difficult to comply with in a residential area. Therefore, it is much easier to keep the plant as cuttings.

In this case, the petunia is looked after in the same way as any other indoor plant. In addition, small pots of cuttings take up much less space than containers of adults.

For winter storage, cuttings begin in late August and early September. At this time, the root layer system develops rapidly. Rooting period is 7-10 days.

The process of such cuttings is identical to the manipulations when dividing the overwintered mother bush.

After rooting, the pots with cuttings are placed in a bright, cool place. A window sill is most suitable for this. You can also put an open container with water there - this increases the humidity of the air. In the spring, the plant can be immediately transplanted into the garden.

To increase the number of plants, overwintered individuals can also be pre-blackened.

Let's watch a video about the correct grafting of petunia:

How to store petunia in a basement or cellar in winter

Storing petunias in a cellar or basement has several features. It is best to place bushes and cuttings in dark, damp rooms just before the very frosts. In this case, the bush is cut very shortly.

Lighting is not required in this case. The climate of the cellar slows down biological processes. Petunia goes into deep hibernation and does not need illumination.

At the beginning of January, it is moved to the windowsill. At this time, you can cut off all excess and slowly start watering. You also need to provide good lighting. Such petunia will quickly come to life and by the end of February will delight the owners with the first flowering.

What is the advantage of winter storage

Gardeners are not wasting time preserving petunias in the winter.

Unlike planting seeds, this reproduction has several important advantages:

  • early flowering: the mother bush or cuttings overwintered indoors can bloom already at the end of February;
  • ease of obtaining seedlings: cuttings are much more viable than sprouts grown from seeds;
  • preservation of rare hybrids that reproduce exclusively in a vegetative way.

Winter storage of various varieties of petunias may have some individual characteristics. An attentive gardener must monitor the condition of the plants and correct the level of humidity, light and temperature in time.

To obtain the desired result, several flowers should be taken into the house. Even if 1-2 plants die, the likelihood of keeping your favorite hybrid will increase.
