When growing seedlings, summer residents may face such a problem as leaf curling. The reasons for this phenomenon and methods for solving the problem will be discussed in this article.
Improper care
The most common cause of curling is improper care. Excessive or inadequate watering, too little light, dryness or dampness in the room can all lead to problems.
Watering the soil should be optimal, it should be slightly damp. If there is not enough light for the plant, additional lighting needs to be installed. The temperature in the room where the plant is located should be about 20 degrees Celsius.
Pests
Leaves can be caused by pests such as spider mites and aphids. They affect most plants grown through seedlings. Aphids are immediately visible, but spider mites are usually invisible, but their presence can be determined by small cobwebs.
You can fight them with a solution of onion husks. One glass of husk is poured with a liter of boiling water and infused for a day. Plants are treated with a strained solution every 3 days.
Lack or excess of nutrients
An insufficient amount of phosphorus and potassium in the soil can have a very negative effect on seedlings, so this must be carefully monitored.
To begin with, it is necessary to exclude the influence of improper care and pests on the plant, so that an excess of fertilizers in the soil does not turn out, as this can also negatively affect the seedlings. If watering is optimal and there are no pests, then the reason in almost 100% of cases lies in a lack of substances. In this case, it is necessary to provide fertilization of the soil with fertilizers.
Diseases
With dampness in the room where the seedlings are located, a fungus can develop on it. It looks like mutating spots on the surface of the leaves.
To eliminate the fungus, 2% Bordeaux liquid is used. She is treated with the plant 1 time in 5 days. This liquid can also be used to prevent the appearance of fungus, in this case, take a 1% solution.
When not to worry
Sometimes it happens that the center of the leaf develops faster than the rest of it. This can cause the entire sheet to curl. In this case, there is no need to worry, after a while development will return to normal, and its form will become normal. Twisted leaves can also be a feature of the cultivated variety.
