Most plants require special soil for successful growth. Petunia is no exception. Soil for petunia must correspond to certain parameters, so that this perennial plant pleased its owners with flowering. A ready-made soil mixture suitable for this particular member of the Solanaceae family can be purchased at a specialized store or prepared independently.

What you need to know for the successful cultivation of petunia

Now we know 25 species of petunia. They differ in the color and shape of the flower. Petunias are loved by flower growers for a long and lush bloom. However, it is necessary to observe certain conditions, so that the plant feels comfortable and pleases the eye.

First of all, it is necessary to select quality seeds that will give seedlings suitable for the further cultivation of petunias. Then you need to provide them with the necessary amount of light and heat.

Seeds come up very quickly - the first petunia shoots appear about the third day after planting. After this growth slows down, the next 3 to 4 weeks may seem that the flower has completely stopped growing. However, this is just a delusion, which can introduce petunia beginner gardener. The whole point is that it is during this period that the root system is formed, therefore, external sprouts are suspended. It is at this stage that the quality of the soil for the petunia seedlings is very important. It must meet certain parameters, namely: have sufficient moisture capacity; the land must be light and loose; the soil should contain the optimal amount of nutrients.

If all the conditions are met, then petunia will soon start to please with its bright colors.

Ready Mixes

Most of the experienced flower growers prefer to mix the petunia seedlings themselves. However, for this it is necessary to have some experience and have a proven recipe. For beginners, a ready mix for petunia seedlings is more suitable. It has many advantages: The earth is ideal for a certain type of plant; the soil is completely sterile, which excludes the presence of fungus and parasites; in the finished soil all proportions are observed; all the necessary minerals are present.

The main factor in choosing a ready-made land for petunias is quality. It directly depends on the peat, which is the basis of the mixture. It can be high and low. The main disadvantage of low-peat peat is its low ability to retain a sufficient amount of moisture, so for solanaceous plants, a horse will be more suitable.

Attention! Horse peat can often have high acidity, which has a bad effect on the growth rate. For petunia seedlings, the ideal index of ph is 5.7. A slight deviation is permissible, but not more than 0.3 in each direction.

On a quality product, the acidity is indicated directly on the package. If there is no such indicator, then you can check it yourself using litmus bills, which are always available in specialized stores for florists.

Reducing the acidity level will help the soil deoxidizer.

How to check the acidity of the soil

This simple test can be done quite calmly on your own. This will require litmus paper and a little water. In a glass it is necessary to collect a soil approximately up to half and top with water. All this is thoroughly mixed and settled.

As soon as the earth settles, paper can be lowered into the water. The optimum color of the reaction is obtaining a purple color.

Less accurate, but no less simple way to test - the use of soda and vinegar. On the ground it is necessary to pour a few drops of ordinary table vinegar. Soda should be poured on a damp soil. The hiss of vinegar speaks of a more alkaline environment, and the hiss of soda is about acid. To make the soil suitable for planting petunias, the hiss of soda should be slightly stronger than vinegar. However, both reactions should not be strongly pronounced.

Another indicator of soil quality for petunia is the level of salts in the composition. If the soil for seedling petunias was taken from greenhouses with a high salt content, then upon drying, a characteristic white coating will form on it.

Select the right mixture for petunias will always help consultants in the store. The main thing to remember is that the best samples are made by German companies, however, and some Russian companies provide enough quality mixes. One of the leaders in the market is the enterprise "Pelgorskoe-M".

After the mark of the finished mixture has been determined, add the disintegrating agents to it. For petunias, perlite or vermiculite is best.

They will increase the water-holding properties of the soil to the level required by the petunias.

Self-preparation of soil at home

If in the nearest flower shop it was not possible to get a high-quality finished mixture or the florist has some experience, then the soil can be prepared independently. The main thing is that the land for planting petunias should be clean. For self-preparation of soil, peat, sand and clean turf ground will be needed.

The main ingredient of any mixture for petunia is peat, as it has high rates of sterility. It is also important to pay attention to what kind of peat is used - horse or lowland. Lowland peat can be recognized by its characteristic black color. And although its acidity is considered more suitable for petunias, it is rarely used.

Soil for petunia is better mixed with the use of peat moss, which has an orange tinge. It is rather loose, which is perfect for seedlings. To reduce its acidity to the required level can be with the help of dolomite flour. If you can not get it, then you can use even ordinary limestone. To reduce acidity in peat, it is necessary to add the selected substance at the rate of 1 teaspoon (about 5 g) per 1 liter.

The next most important component of the mixture for petunias is sand, which adds the necessary porosity. Of course, it must be clean and sifted. The main indicator of quality is the color of sand, it indicates the presence of iron oxide. This substance has a very negative effect on the growth of plants, so its presence in the soil should be minimized or completely eliminated.

Sand, rich in iron oxide has a more orange color with shades of rust. Consequently, the lighter the sand, the less harmful substance in it. The best option for the soil will be white, river sand with fine granules. The material of a grayish shade will approach also.

Peat and sand are mixed in proportions of 1: 1 and the basis for the soil is obtained. The pure mix will not be nutritious enough, therefore in a ground for petunias it is necessary to add some more ingredients.

Important! Petunia has a very delicate and sensitive root system, especially in the early stages after seeding, so all ingredients, especially peat, must be carefully sieved for the mixture.

If the soil is too large particles or any extraneous granules, then the root can rest against the soil, and the plant will die. Additives for the mixture

To ensure that the seedlings receive all the necessary substances and minerals from the soil, the earth is enriched with some additives.

The most common additive for the soil is "Epin".

Many gardeners consider this substance is a hormone, however, this is just another misconception. "Epin" is an acid that is synthesized from plant cells and provides active growth. It is used to accelerate the process of sprouting petunia. "Epin" can be purchased at any horticultural store in the form of an ampoule, which should be diluted with water in the amount of one liter. The resulting mixture is poured into a spray and sprinkled with soil, and then the petunias themselves.

As a baking powder for planting petunia at home, the perlite already mentioned is used. It is a mineral of volcanic origin, which is accessible to every grower.

Depending on the peat that was used to create the soil mix for planting petunia, an additive such as a hydrogel may be required.

It is also in free sale and helps increase the water retention properties of the soil.

The ground for planting petunia should contain and trace elements. They can be purchased in pure form or added to the mixture of humus or compost. Disinfection

If the presence of fungus and parasites in a quality ready-made ground for petunia is completely excluded, then land for petunias cooked at home needs additional disinfection in order to protect plants.

The simplest folk remedy for disinfecting the soil is the usual solution of potassium permanganate. The amount of potassium permanganate is added to the water so that the solution is saturated pink and not dark.

This mixture is abundantly watered pre-prepared land about 3 days before the proposed planting of petunia. This helps to get rid of the most pathogenic factors for petunia.

On the other hand, the ground for petunias should be as sterile as possible, since these tender plants are susceptible to even the simplest diseases and microbes that can be found in untreated soil. Experienced gardeners consider simple calcination as the most effective way to clean the soil on their own. At home, it can easily be carried out in three ways: steaming on the stove; in the oven; in the microwave.

Calcination of soil in any way resembles the preparation of simple dishes. For example, to bake the soil on the stove you need a water bath. To do this, the land must be placed in a pan, filled with water and put in a larger pan, after having previously collected water and there. Thus, a water bath is obtained. Pots are put on the stove, as soon as the water in the bottom boils, you need to reduce the temperature and heat the ground for about 2 hours. Add water as it boils.

Calculating the ground for petunias in the oven is much easier. To do this, you need only a package for baking. It should be placed heavily moistened earth, after which the package is tied, pierced in several places with a fork or knife and sent to the oven. It should be heated for 50 minutes at a temperature of 150 degrees.

Disinfection in the microwave has recently become popular, but this method is also quite simple and fastest among all possible. In addition, it most effectively destroys any fungus and all pathogenic and harmful for petunia microorganisms.

To sterilize the soil in a microwave oven, the earth should be poured into a plastic container and filled with water until the swampy state.

The mixture is then thoroughly mixed and sent to the microwave for 6 minutes at full power. This time is enough that the radiation destroys all the microbes that pose a threat to fastidious petunias.

Attention! All fertilizers and baking powder should be added to the mixture for petunia only after the ground has completely cooled down.

There is nothing complicated in the independent creation of a mixture for seedlings. It's enough just to observe the proportions and use the quality ones materials, then petunias will grow up healthy, and after a short time will please others with their magnificent flowering.
