Growing Environment of Sunflower
Sunflowers prefer a warm, sunny, and well-drained environment. During the growing period, sunflowers need plenty of sunlight and water to grow rapidly.
Growth Cycle of Sunflower
The growth cycle of a sunflower is usually 4-5 months. During this period, it goes through different stages such as seed germination, seedling stage, maturity stage, flowering stage, and fruiting stage.
Seed Germination Stage
During the seed germination period, the sunflower seeds begin to absorb water and nutrients, break through the seed coat, and grow outward to form seedlings.
Seedling Stage
During the seedling stage, the sunflower requires suitable temperature and humidity conditions as well as sufficient sunlight. At this stage, the sunflower begins to form roots and leaves, and the plant gradually becomes sturdy.
Maturity Stage
When the sunflower enters the maturity stage, it forms a stable and healthy plant. At this time, the sunflower begins to focus on growing upwards and converts more energy into growth for the next stage.
Flowering Stage
The most beautiful moment in a sunflower's life is the flowering stage. At this time, the sunflower will produce large and small yellow or orange flowers, presenting their most splendid side to the sun.
Fruiting Stage
After the flowering stage, the sunflower enters the fruiting stage. At this time, the sunflower begins to form fruits, which will become the seeds for the next season.
