Characteristics
Sunflowers are a favourite among gardeners because of their many attributes. Their tall stems and large, vibrant blooms add a striking visual appeal. The traditional sunflower has a disk-shaped centre and bright yellow petals that form a recognisable floral pattern. Because these flowers are heliotropic, they exhibit solar tracking, the behaviour of tracking the sun’s movement throughout the day.
Cultivation
Growing sunflowers from seeds
Sunflower cultivation frequently starts with seeds. After the last frost, choose premium seeds from reliable vendors and plant them straight into prepared soil. Sunflowers are comparatively simple to grow, but give them the right amount of support and space for best results. Robust growth is facilitated by nutrient-rich soil and regular irrigation.
Ideal growing conditions
Sunflowers are sun-loving plants requiring direct sunlight to flourish. They favour loamy, well-drained soil that ranges in pH from slightly acidic to neutral. It’s crucial to leave enough space between plants to avoid overcrowding. Sustaining steady moisture during the germination process is essential for the establishment of healthy seedlings.
Care tips for sunflowers
Watering
Sunflowers must be watered frequently, particularly in dry spells. Remember not to overwater them because wet conditions can lead to root rot.
Fertilising
To encourage rapid growth, apply a balanced fertiliser during the growing season. In particular, phosphorus is suitable for solid flower development.
Support
In particular, in windy circumstances, taller sunflower cultivars may require staking or other forms of support to avoid bending or breaking.
Deadheading
Prune blooms to promote ongoing blooming and to refocus the plant’s energy on developing new buds.
