How long is the growth cycle of a sunflower?

Introduction to Sunflower Growth

The suitable temperature for growing sunflowers is 15-30 degrees, but it grows faster in summer. The growing period is 2-3 months. The temperature during the growing period must be above 28 degrees. The flowering period can reach more than two weeks. It mainly grows in Xinjiang, Ningxia, Inner Mongolia, Gansu, Northeast China and other regions.

Sunflower growth cycle

Sunflower is a light-loving flower that prefers a warm, slightly dry and sunny environment. It needs sufficient sunlight throughout its entire growth and development period. Its growth cycle is generally more than 85 to 120 days.

Sunflower growth rate

The entire growth period of sunflower is divided into seedling stage, bud stage, flowering stage and mature stage. From seedling to bud is called seedling stage, which generally takes 35 to 50 days. From bud to flowering, it generally takes about 20 days. From flowering to maturity, it takes 25-55 days.

Sunflower growth cycle management

The yield of sunflower per mu is about 450 to 550 kilograms. It grows quite quickly and usually blooms about two months after planting. It can be single flower, multiple flowers, single petal or double petal.

Temperature management: During the growth of sunflowers, a temperature difference of 8-10℃ is most beneficial to the growth of stems and leaves. If the temperature is low in early spring, the plant will grow slowly. If the temperature exceeds 30℃ during the growth period, the leaves of the plant will tend to grow too long and the flowering period will be shortened.

Fertilization management: Sunflowers can be fertilized with urea, potassium chloride, or decomposed human feces, wood ash, etc. After planting, dig a few holes 2 to 3 cm deep around the plants and apply fertilizer into them.
