How many days does it take for a sunflower to germinate, bloom and bear fruit?

It takes about 60 days for sunflowers to bloom from sowing , and they bloom continuously from late July to September every year.

Generally, sunflower seeds germinate in 5-7 days after sowing. It usually takes 35-50 days from germination to budding. If it is sown in summer, it usually takes 28-35 days. It usually takes about 20 days from budding to flowering.

In North China, it takes 4 to 5 weeks for sunflowers to grow from planting to growing into stalks, 10 to 15 days from flowering to producing seeds , and about a month to mature.

The growth process of sunflower

Seedling stage

Sow sunflower seeds in spring and wait 5-7 days, the sunflowers will sprout . The seedling stage starts from the beginning of germination to the formation of sunflower buds.

The seedling stage lasts about 30-50 days . During this period, the sunflower will continue to grow, the rhizome will continue to grow taller, and the leaves will also increase from 1-2 leaves to multiple leaves. In addition, the roots of the sunflower will also thrive underground during this period.

Bud stage

After the seedling stage, when the top of the sunflower grows a star, it will last until the sunflower blooms, which is the budding stage of the sunflower.

The budding period of sunflowers lasts about 20 days . During this period, the sunflower will work hard to absorb nutrients and grow more vigorously, and its flowers and leaves will continue to grow.

Flowering period

During the flowering period, three-quarters or more of the sunflower flowers begin to bloom, and the period until the flowers are fully open is the flowering period. This period lasts about 6 to 9 days , but please note that pollination will shorten the flowering period.

Maturity

The period from when the sunflower blooms until the sunflower seeds are fully mature is the maturity period of the sunflower, and this stage will last approximately 25 to 55 days.

During this period, the sunflowers are pollinated. If the amount of water, temperature and light are appropriate, the sunflower seeds will be fully mature in about 1 month .
