The petunia - plant quite whimsical, and not at all turns out to grow up these beautiful flowers from seeds. Seedling causes of death set therefore to everyone to have these florets on the garden site, it is necessary to get acquainted with all subtleties of cultivation of petunia.
Why the petunia badly ascends
If during the term specified on bag the seeds of petunia do not ascend, then the reasons can be a little. One of the most widespread - ""dead"" seeds (to it old seeds and also seeds which were stored incorrectly belong). One more reason of not viability of seeds - their too deep landing.
Why seeds of petunia have ascended, but seed covers have not dumped
The most common cause - to sprouts is not enough forces it to make. It can occur because indoors too dry air (cover too firm) and also because seeds very weak in itself. Air moistening will help with the first case (it is possible to place seedling under film or accurately by means of the pipette to moisten covers with warm water). In the second case sprouts you should not save as most likely here nothing will help, at such seedling too weak immunity.
Why at petunia the stalk becomes thinner and breaks
If petunia shoots fall, then most likely seedling has undergone such fungal disease as "black leg". In this case the small site of stalk darkens, begins to rot and the plant falls (breaks off) under weight of curb weight. Most often this disease attacks seedling which is contained in too warm damp conditions, badly air and fertilize nitrogen fertilizers. To save seedling from this disease, it is necessary to look after it properly. If the disease nevertheless has overtaken, then first of all it is necessary to get rid of sick sprouts, to change the soil healthy and to process its 40% formalin solution.
Why seedling of petunia turns yellow
If the top young leaves turn yellow, and on them green streaks, then the reason - chloroz-lack of iron are visible. This problem is solved easily: it is necessary to bring ferriferous medicine in the soil. If the lower leaflets turn yellow, then it is necessary to moderate watering of plants and to feed up them nitrogen-containing complex fertilizers.
