Zinnia seedlings turn yellow: why and what to do?

Last year my zinnia seedlings were almost completely ill. What exactly, I do not know, but the leaves at the seedlings gradually turned yellow, and in some plants they even crumbled. Not everyone was saved. I would like to avoid such mistakes this season. Tell me why the zinnia seedlings turn yellow and how to deal with it?

Growing zinnia in seedlings is widely practiced by flower growers, as it allows these beautiful plants to bloom earlier. However, handsome majors have a slightly capricious character, which manifests itself even at the seedling stage. Often young seedlings begin to lose their color, and the leaves gradually turn yellow. To prevent this situation, you need to know why the zinnia seedlings turn yellow.

The main causes of yellowing of seedlings are:

• freezing;
• lack of nutrition;
• close landings;
• root damage;
• lack or excess of moisture;
• lack of lighting;
• the presence of a disease.

Freezing seedlings

Zinnia is very sensitive to low temperatures, even short-term freezing of seedlings leads to their damage and yellowing of the leaves. It is especially important to avoid drafts when airing greenhouses with seedlings and not to leave containers near open windows.

When growing zinnia with seedlings in the open field at night, it is necessary to cover the plantings with foil.

Lack of nutrition

For full development, zinnia seedlings need loose and nutritious soil. Lack of nitrogen and other microelements in the soil can cause yellowing of seedlings.

It is necessary to regularly feed the seedlings with nitrogen and complex mineral fertilizersso that the plants have a sufficient supply of nutrients for active growth.

Close planting and root damage

Yellow leaves of zinnia seedlings also appear in the case of thickened seedlings, when they do not have enough space for growth, as a result of which the plants are intertwined with roots and struggle for survival. It is necessary to plant the zinnia in separate cups, being careful not to damage the thin roots, which in turn can lead to discoloration of the leaves and further death of the seedlings.

Violation of the watering regime and lack of light

Leaves of young zinnia may turn yellow as a result of missed or insufficient watering. It is important not to allow the soil to completely dry out, but also not to flood the seedlings. With an excess of moisture, the process of decay may begin, which will lead to the death of seedlings.

Lack of lighting leads to yellowing and stretching of seedlings, therefore containers with zinnia must be placed in a sunny place.

Seedling disease

Fragile seedlings are defenseless against various diseases. Seedlings are often prone to wilting, which manifests itself as yellowing of the leaves. First, the lower leaves turn yellow, gradually the sprout becomes sluggish and dries up. You can try to save the remaining zinnias by shedding the soil with a weak solution of potassium permanganate. For the prevention and treatment of the disease, spray the gatherings with Baktofit.

Completely wilted zinnia seedlings should be carefully removed from the soil.
