When is the best time to plant sunflowers?

The sunflower, also known as pine peony and half-branch lotus , is a perennial flower of the genus Portulaca . This plant likes warm, sunny and dry environment, and has a very long flowering period. It is usually sown in spring, blooms in summer, and can continue to bloom until late autumn. So when is the best time to plant sunflowers? Let’s take a look below.

1. When is the best time to plant sunflowers?

There is no strict requirement for the planting time of sunflowers. It is best to plant them in spring, and March to April is the best planting time. Because the climate in spring is mild, it is suitable for plant growth and the survival rate is high. The soil must be loose and fertile with good air permeability and drainage. The plant grows best at a temperature above 18 degrees, and the light time should be maintained at more than 8 hours a day.

2. How to plant sunflowers

1. Choose the right time: Sunflowers are warm season plants and are best sown in spring or summer. Make sure the soil is thawed and the temperature is comfortable for the seeds to germinate and grow.

2. Prepare the sowing container: Choose a suitable container, such as a pot, flower bed or planting box. Make sure the container has adequate drainage holes to avoid water accumulation that could affect the growth of the seeds.

3. Prepare the soil: Sunflowers prefer fertile, well-drained soil. You can use flower soil or a mixture of soil and leaf mold to prepare the soil for sowing. Make sure the soil is moist but not too wet.

4. Sowing seeds: Gently sprinkle sunflower seeds on the surface of the sowing container. The seeds can be pressed slightly, but do not cover them too thickly with soil. Sunflower seeds are large, so they do not need to be covered too deeply and can usually be sprinkled directly on the soil surface.

5. Provide appropriate light and temperature: Sunflowers are sun-loving plants and need plenty of sunlight to grow healthily. Place the seedling container in full sun and make sure the temperature remains within a comfortable range, usually between 20-25 degrees Celsius.

6. Keep the soil moist: Keep the soil in the sowing container moist, but avoid overwatering as this may cause the seeds to rot. Use a spray bottle or gentle watering to keep the soil moist.

7. Wait for germination and growth: Sunflower seeds usually begin to germinate within one to two weeks. Once the seeds germinate, keep the soil moist and gradually acclimate to the intensity of sunlight to avoid seedling burn.

8. Thin the seedlings: When the sunflower seedlings grow up, leave the stronger seedlings and keep the appropriate distance between them so that they have enough space to grow.
