1. Prepare the soil: When planting dianthus, you need to use slightly alkaline, soft and breathable soil. Before planting, they should be laid out in the sun to be sterilized.

2. Prepare seeds: When planting it, use healthy and undamaged seeds. Before planting, the seeds need to be screened to remove shriveled and insect-eyed seeds.

3. Sowing: Prepare a flower pot with good air permeability and put the sun-dried soil into the flower pot. Then, spread the seeds evenly on the soil surface in the pot and cover them with a thin layer of soil.

4. Later maintenance: After sowing, you need to put it in a warm place. It is best to keep the temperature between 21-22°C, which is the optimal temperature for their germination. Before germination, water needs to be sprayed into the soil regularly to ensure that there is a certain amount of moisture in the soil. This is also needed for seeds to germinate.
