Step-by-Step Guide To Grow Sunflowers at Home From Seed
- Method: Sunflower seeds are mainly sown directly in gardens or pots because they have long roots and do not like to be transplanted.
- Germination temperature: Sow sunflower seeds when the soil temperature is 21-29°C for faster germination.
- Sowing seeds: Plant sunflower seeds 1 inch deep in the soil.
- Spacing: If you are planting 1 seed in a pot then sow the seeds in the center of the pot. If you are sowing seeds of several dwarf varieties in one pot, maintain a distance of at least 6 inches between the seeds.
- Watering: Sunflower seeds require a lot of water to germinate, so keep the soil consistently moist until germination occurs.
- Sunlight: Keep the pots or containers in a sunny location.
- Germination: With proper care, sunflower seeds germinate in 7-10 days after planting, depending on the variety and growing conditions.

How To Care For Sunflower Plants
After knowing how to grow sunflowers from seeds at home, let’s learn its care tips to get better and healthy flowers.
- Watering: Sunflower is a drought-tolerant plant but regular watering ensures better flowering. Once the plant is established, water deeply around the roots. Before watering, constantly check the soil whether it is dry or not. If the soil is dry, water thoroughly.
- Sunlight: Since sunflowers are heliotropic (flower heads follow the sun) provide sunflower plants with 6-8 hours of direct sunlight for best flowering and direct plant growth.
- Fertilizer: Sunflowers require moderate fertilizers, do not over-fertilize the plant as this may cause stem breakage. Phosphorus-rich fertilizers like bone meal, PROM, and rock phosphate fertilizers are good for bigger flowers, and potassium-rich fertilizers like organic potash fertilizers are good for root growth, while nitrogen-rich fertilizers like cow dung manure, vermicompost, or mustard cake fertilizer encourage foliar growth.
- Common Pests and Diseases: These are generally pest-free plants, but occasionally a small grey insect lays their eggs in flowers. Diseases like powdery mildew, downy mildew, and rust infect the plant. You can use common garden fungicides to control these diseases.
Blooming Sunflower
- As sunflower plants mature, they produce large, vibrant flowers that track the movement of the sun.
- Sunflowers bloom within 70-100 days after planting. Generally, it blooms from summer to autumn.
