Sunflower is also called sunflower. Generally speaking, if sunflower is planted in April, the flowering period is from July to August, and the mature period of seed 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 have accumulated a certain temperature in the process of growth.
When sunflowers bloom, it usually takes 6-9 days for a flower plate to open from the tongue like flowers to all flowers. From the second day to the fifth day when sunflower blooms, it is in full bloom.
Sunflower flowers bloom at 4-6 a.m. and can be pollinated the next morning. If they are not pollinated, the flowers can stay 7-10 days.
Sunflower flowers are still very eye-catching. There are single petals and double petals. At first glance, it looks like a big flower plate. There are two kinds of flowers on the flower plate of sunflower, one is glossy flower, the other is tubular flower.
