Sunflowers are usually sown around February to April every year, and it takes about 60 to 80 days for the seeds to develop and mature until they bloom.According to the growth cycle, the flowering period of sunflowers is in summer, which happens to be the hottest July and August.At this time, sunflowers bloom one after another, as if urging each other.
However, if some sunflowers are planted late, their flowering period will be delayed.Because sunflowers are vigorous and can be sown all year round, it is also common to blossom in May or October.
Because the planting time of sunflowers is not consistent, the flowering season is also inconsistent.But most of them will bloom in July and August, that is, in summer.Others are open in late spring, early summer or early autumn.
Delaying pollination time: Sunflowers generally fade after the beginning of fruiting, and if pollination is delayed, the fruiting time can be delayed.As long as insects such as bees and butterflies are not allowed to approach the sunflower when it blossoms.
Ensure adequate light: Sunflowers grow in the sun, there must be adequate light to grow better.The flowering period should be guaranteed to have sufficient sunshine, which will make it more colorful and the flowering time will be relatively prolonged.
Control the amount of watering: The sunflower itself does not like water, so you must pay attention to control the amount of watering during the flowering period.Too much water will make it grow faster and speed up the end of the flowering period.On the contrary, the flowering period will be relatively longer.
Keep it warm: Some sunflowers are planted late and bloom late, so you need to keep it warm at this time.Warm conditions will make it bloom longer, and too low temperatures will make plants wither and wither.
