Sunflower Planting Time and Method：

Sunflowers are suitable for planting between April and June in spring. The suitable temperature for sowing is between 18-25 ℃. Mature, plump, and disease-free seeds should be selected. Before sowing, the seeds should be germinated to improve survival rate. One end of the seed tip should be inserted into the soil, and a thin layer of soil should be covered after planting to keep the soil moist. Then, it should be placed in a semi shaded area for maintenance.

Sunflower Planting Time：

Sunflowers are suitable for planting between April and June in spring. When the temperature stabilizes between 18-25 degrees Celsius, this environment can germinate better. The specific time depends on the region. If it is in the northern region, the planting time is probably after May. If it is in the warm southern region, the planting time can be appropriately advanced, and it can be planted around April.

Sunflower Planting Methods：

1. Seed selection

Choose mature, plump, and disease-free seeds. Before sowing, promote germination to increase survival rate. Wrap the seeds with moist gauze and place them in a warm environment. After 2-3 days, the seeds will sprout.

2. Sowing

The suitable temperature for sowing is between 18-25 ℃, usually around 20 degrees Celsius. The tip of the seed should be inserted into the soil, not too deep. After planting, a thin layer of soil should be covered, and water should be poured to keep the soil moist. Then, it should be placed in a semi shaded area for maintenance.

3. Transplantation

After 2-3 pairs of true leaves of sunflowers sprout, they can be transplanted. Prepare a slightly acidic soil with good drainage and breathability to neutral sandy soil, apply some base fertilizer to increase the nutrients in the soil. After planting, move it to a cool and ventilated place, wait for it to grow, and then place it in a sunny place. If well maintained, it will bloom in less than two months.

Notes on Sunflower Planting：

After planting sunflowers, attention should be paid to maintenance methods, timely watering, and maintaining soil moisture. However, water accumulation should not occur. Pot soil should not be excessively damp, and watering should be controlled between the seedling stage and the bud stage. Watering should be increased during the bud and flowering stages. In addition, sunflowers are sunny plants, and sufficient lighting conditions should be provided when they begin to sprout and grow.
