Best planting time for the sunflower seeds
Spring and autumn are the best times for planting sunflower seeds. Seeding is usually recommended for march-may or september-october in the spring or autumn. During this period, the temperature is moderate and stable, facilitating seed gerontization and seedling growth。
Why sow in spring and autumn
The choice of spring and autumn seeding is mainly due to the fact that the climatic conditions of these two seasons are the most favourable for the emergence of the seeds of the sun. The spring is warm and wet, while the autumn is relatively cool and dry, but the temperature is still appropriate. These two seasons avoid the adverse effects of high summer temperatures or severe winter temperatures on seed growth and seedling growth. The sunflowers like plenty of light but fear strong direct sunlight, a need that can be met in the spring and autumn seasons。
Preparation for planting
Before seeding, some preparatory work is needed to ensure that seeds are successfully sprung. Soils that are lax and well drained are selected as the planting matrix. In order to increase the gestation rate, seeds can be placed in warm water for one night. The soil is kept moderately humid after seeding, while being placed in bright but avoiding strong sunlight. Appropriate shades help protect seedlings from strong light。
How to look after the seedlings
Once seeds begin to germinate, appropriate care is needed to promote their healthy growth. Keep the soil wet rather than overwet to prevent root decay. As the seedlings grow up, they can appropriately increase the intensity of light and produce a suitable amount of liquid fertilizer to supplement nutrition over the long term. The plants are regularly checked for signs of disease and pests, and appropriate control measures are taken. Through these careful care, the saplings will thrive and eventually bloom beautiful flowers。
