If the sowing dates are earlier, the seedlings will need to be illuminated.

For sowing, use the soil prepared since autumn. Soil mixture consists of humus, garden soil and sand, taken in a ratio of 1: 1: 2.It is poured into containers in which the petunia will grow, and left to freeze. A few days before sowing petunias, containers are brought into the house for thawing. Before sowing, the soil is additionally decontaminated from pests and pathogenic flora.

  1. coated;
  2. clean.

Immediately after sowing, the soil is shed with a solution of a previquor( 0.1%) to protect the seedlings from the fungus. In order not to wash up small seeds, it is necessary to disinfect the soil by irrigating through a small strainer.

Until the emergence of shoots, the containers with plantings are covered with glass or a piece of polycarbonate. It is necessary to water the soil if necessary, using a spray.


The first shoots appear on day 5.Thick plantings need to be thinned out, for which extra seedlings are plucked.

For normal growth of seedlings of petunia, a temperature of 20-22 degrees is necessary. With the appearance of petunia shoots, the shelter is removed and the containers are transferred to a room where the temperature does not exceed 18 degrees.

Sowing in granules?

Many expensive varieties of petunia are sold in pellets. How to sow petunia in this case?
In the box with the soil, you need to cut shallow grooves, shed them well and put strips cut from paper napkins. Seeds in granules neatly spread on wet strips.

Crops must be spilled through a spray bottle, boxes covered with foil and left in a warm place until germination.

The period of petunia sprouting in granules is somewhat longer - 10–20 days with the additional lighting of the fluorescent lamp. It is important that the emerged shoots immediately receive enough light, which will prevent them from pulling out.

With the formation of the first true leaf, the crops of petunias are aired, the film is removed and the temperature is reduced to 16 degrees. When the third leaf appears, the seedlings are thinned, setting aside extra plants. You need to know how to plant a petunia and care for it. It is not allowed to overmoisten the soil in plantings - watering is carried out every 3 days, as the soil dries out slightly. This mode stimulates the development of the root system, and the seedlings are more viable. Grown plants pinch, which is why petunia begins to branch. If petunia is sown early, the apical portion can be rooted.
