When does it bloom

Sunflowers are also called sunflowers. Generally speaking, if sunflowers are sown in April, the flowering period is from July to August, and the maturity period of seeds is from August to September.

However, when cultivating sunflowers, we can take measures to make them bloom all year round, which requires accumulated temperature. Basically, plants can bloom when they accumulate a certain temperature in the process of growth.

Flowering mechanism

When sunflowers bloom, it usually takes 6-9 days for a disk to open from tongue like flowers to all flowers. The second day to the fifth day of Sunflower Bloom is its full flowering period. There are a lot of words in these days.

Sunflower flowers bloom at 4-6 a.m. and can be pollinated the next morning. If they are not pollinated, the flowers can remain unchanged for 7-10 days.
