Growing up the seedling of petunia, flower growers often face problem when, apparently, and seeds of petunia have given good shoots and have started in growth, but suddenly suddenly began to fall. What happened and as it to avoid?
Let's consider the most widespread defects connected with the infantile seedling period at petunia.
Insufficient lighting also the petunia leads to pulling of any shoots not exception. Each sprout lasts in light, and roots were not created yet, and they are not able to hold "long body". The result - petunia falls.
Insufficient moisture of soil and air. First of all, it concerns seeds in granules. These seeds need bigger humidity. At its shortcoming the seeds do not dump cover, are extended, taking out on ""to the head the granulated hat" "and fall. In this case it is necessary to cover the crops in tanks with transparent covers, glass, film to keep humidity in the soil and humidity of air layer in capacity. Between the soil and cover there has to be air layer.
Dehumidification of the soil. As a rule, sow small seeds of petunia in small soil layer where it quickly dries up. Because of lack of moisture the small sprouts perish.
Sharp change of temperature and air humidity leads to loss of small shoots. Such situation arises when at capacity sharply uncover (film). ""Hothouse seedlings"" should be prepared gradually for new changes and to air them regularly, accustoming to open conditions of keeping indoors.
Appearance of disease ""black leg"" - the most unpleasant situation. Overwetting and sour soil soil promote mushroom infection which ""mows"" petunia.
Council. Considering superficial feature of crops of seeds of petunia, after emergence of shoots to the basis of seedlings accurately several times pour the sifted soil, the calcinated bank sand. It does "strong legs", promotes the best rooting of plants and protects from ""black leg"".
