Sunflowers require full sun (at least 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. Support taller varieties with stakes as they grow. Fertilize sparingly, as too much nitrogen can promote foliage growth over flower production.
