In the spring, many boxes with seedlings can be seen on the windows. They begin to grow it in advance, so that later, when it gets warmer, it can be transplanted into the beds in the garden. Further harvest depends on properly grown seedlings. But very often the seedlings die on the windowsill, without waiting for the moment of disembarkation. This happens for several reasons.
The first sign that something is wrong with the seedlings is yellowing of the leaves. The reason for this is bright sunlight and poor watering. To prevent this from happening, it is necessary to ventilate the room more often, make sure that the earth does not dry out, and most importantly, do not leave the plants in direct sunlight. The lack of light and nitrogen causes the plants to weaken and cannot grow further. To prevent the seedlings from dying, you need to organize additional light and feed it with urea every week. In addition, a tick can be the cause of death. Its presence is easy to recognize if you carefully examine the leaves. They are small, dark in color and a small cobweb is visible on them. In this case, you should definitely treat the seedlings with "Tiovit" or "Jet", you can use any other drug against pests. Constant flooding of the roots can lead to death. Waterlogging of the soil leads to partial, and sometimes complete, decay of the root system. To prevent this from happening, it is necessary to reduce watering and make several additional drainage holes through which the water can drain freely. Fertilizing plants continuously can cause an overdose that will ruin the seedlings. Therefore, carefully monitor how often you feed your plants, and in case of an excess of feeding, spray the seedlings several times with plain water. One of the most common problems with seedlings is black leg disease. She is able to destroy all sown plants in a short time. You can fight this disease by etching and warming the earth. Seedlings are treated with a weak solution of potassium permanganate, and the soil is sprinkled with calcined sand. It is important to take into account that the sand must cool, otherwise the stems of the plants can be damaged. A diseased plant must be planted in a separate container. And all the rest should be treated as a preventive measure.
