Planting Method
Sowing: Sprinkle the seeds evenly onto the soil and maintain a temperature above 20 degrees Celsius. Germination typically occurs after about 10 days.
Transplanting Seedlings: Once seedlings reach a certain height, they can be transplanted separately. In soil cultivation, there’s no need to add extra soil or water during the growth period. Maintain proper spacing between plants and apply liquid fertilizer several times throughout the growing season. Additionally, remember to harvest the seeds promptly before the fruit cracks and scatters. For potted plants, follow the same transplanting method as for soil cultivation.
- Watering: The frequency of watering should be based on the moisture level of the potting soil. Generally, avoid watering if the soil is still moist. When watering is necessary, ensure to water thoroughly all at once.Fertilizing Properly: Sunflowers do not require heavy fertilization. Applying potassium dihydrogen phosphate once every two weeks is sufficient. This promotes large, colorful flowers and extends the flowering period.
- Light: Sunflowers thrive in sunny locations, so it’s important to place them where they can receive ample sunlight to ensure lush growth and abundant foliage.Temperature: Sunflowers prefer warm environments. The optimal germination temperature ranges from 21 to 24 degrees Celsius, allowing seedlings to emerge in approximately a week.
Maintenance:
Sunflowers exhibit robust vitality and adapt well to various conditions. They thrive in warm, sunny environments and are highly tolerant of drought and heat. They prefer loose, fertile sandy soil that is well-drained. During spring, they can be placed in a bright indoor location for care, with room temperatures ideally above 15 degrees Celsius. Avoid overwatering during this time.
Sunflowers fear neither sun nor rain. During summer showers, place them outdoors to benefit from the rain. Ensure proper drainage in the pot to prevent waterlogging. Increased rainfall promotes robust growth, encouraging the development of new buds and branches, leading to rapid growth.
