Seedlings need to be watered correctly so that they grow and develop well.
Water for irrigation
Watering with tap water is not possible because in many regions chlorine is added to it. But you can, at home, pass the water through the filter and let it warm up to room temperature. The best water for watering plants is snow or rain.
Specialists recommend the optimal temperature of water for watering seedlings at least 20 and not more than 25 degrees.
Cold water is not suitable because it can cause root rot on plants. And it’s hot, too, because oxygen is lost during boiling.
It all depends on the stage of seedling development.
Until the first shoots appear, you need to moisten the soil once a day. Use a sprayer so that there is no crust on the surface of the soil. After the appearance of the first shoots, do not water for two days so that the seedlings get a little stronger. Then water once a week.
When 2-3 leaves appear on the plants, you need to water more often, but always monitor the moisture of the soil itself. To do this, stick a wooden stick into the ground so as not to overmoisten the ground. This can have a negative effect on seedlings. Different plants need different amounts of moisture, for example: cabbage and cucumbers need daily watering, while peppers, eggplants and tomatoes need much less.
Seedlings should be kept on the south side of the windowsill. Do not overmoisten, so that the plants do not get sick with black leg and other fungal diseases. At the bottom of the container, you need to put a layer of drainage so that there is no stagnation of water. The drying out of the soil also does not contribute to the better growth of seedlings.
Watering in the greenhouse
In the greenhouse, plant seedlings are watered under the root so that water does not get on the leaves, because this can cause an outbreak of late blight. It is recommended to water 2-3 liters of water once a week. This should be done in the morning or in the evening, then ventilate the greenhouse and loosen the soil so that a crust does not form.
Watering before transplanting into open soil
Watering is stopped before this procedure. But a few hours before planting seedlings in the ground, it is necessary to water abundantly so as not to damage the roots during transplanting. Next, the ground around the plant is mulched to prevent moisture from evaporating from the soil. Watering after transplanting plants into open ground is necessary only after 10-15 days.
