First, you need to check the seeds for germination. It's very easy to do.
You need to leave the planting material in water for a day, then cover it with a damp cloth and do not let it dry out for another five days.
If half of the seeds hatch, it means they are of good quality.
There is another way to prepare seeds. To do this, mix a liter of water with one tablespoon of hydrogen peroxide. After soaking, spread the seeds on a saucer for several days. They should germinate.
When planting, remember that the soil must be moistened, and the seeds themselves must be located at a distance of 10 cm from each other.
The temperature when growing seedlings should be about 17 degrees Celsius. It is also necessary to provide sufficient sunlight for this crop.
As soon as the first leaves appear, you need to transplant.
As for planting seedlings in open ground, the plants should be about two months old.
