Sunflowers require full sun (6-8 hours of direct sunlight daily). They prefer well-draining soil and should be watered regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged. Once established, they can tolerate some drought. Fertilize sparingly, as too much nitrogen can lead to lush foliage but fewer flowers. Support taller varieties with stakes as they grow.
