The seeds of ornamental sunflowers vary in size. For large seeds, 25-50 seeds per gram. There are 110 small seeds. The best choice for potting is small seeds, 5-8 seeds per hole.

Transplanting should be done early, when the plant grows a pair of true leaves. The survival rate can be improved by transplanting the seedlings into the prepared flowerpot, extending the root system and leaving enough space for their growth.

After transplanting, the plants were placed in the shade for 2-3 days, and then the plants were planted with proper watering and fertilization. Keep the soil moist to prevent overgrowth.
After 30-40 days, the plant buds should be watered properly according to the actual situation to meet the growth needs.
