Find a container like a flowerpot. Put about 80% loose soil in the container, and leave a small part of dry soil for use. The soil should be fertile and loose, and the pH should be slightly acid.
In the container, evenly sprinkle a little water, not too wet (spray a few drops, slightly wet). Sprinkle the prepared seeds of Impatiens on the soil, you don't need to sprinkle them too intensively, just keep a proper distance.
After sowing the Impatiens seeds, cover them with dry soil. As long as the top layer of dry soil is very thin, it can cover the seeds. Don't spread it too thick.
Put the flowerpot in a place where you can receive sunlight, but you should prevent the temperature from being too high and exposure to the sun. Water each day in the morning and evening to avoid watering the seeds of Impatiens at noon. The amount of water should not be too much.
After the seeds of Impatiens germinate, they need to be transplanted. I usually wait for the Impatiens to grow four leaves before transplanting. In the process of transplanting, try to avoid exposure to the sun, and the transplanting should not be too dense. The plant spacing is about 30 cm.
After planting, water the basin soil timely, keep the basin soil moist, but do not accumulate water, and pay attention not to make the soil too wet for a long time, otherwise the root and stem are easy to rot.
