The life code from sowing to blooming
When the spring breeze of April awakens the earth, sunflower seeds planted in the soil quietly germinate. After a growth cycle of 90-120 days, the golden sea of flowers can be seen surging in early July. In the northern regions, due to climatic differences, the blooming period is postponed to the first decade of August. With temperature control technology, modern horticulture has made it possible to enjoy flowers all year round.
Secrets to caring for sunflowers in three blooming stages
During the initial bud stage (6-9 days), it is necessary to maintain 6 hours of direct sunlight daily and use phosphorus and potassium fertilizers to promote the differentiation of flower buds. In the full bloom stage (days 2-5), water thoroughly in the morning and evening, and spray 0.2% urea solution weekly. Be sure to remove the yellow leaves at the base in time to ensure the concentrated supply of nutrients to the flowerhead.
