Plant in full sun (at least 6-8 hours of direct sunlight daily). Sunflowers prefer well-draining soil and can tolerate a variety of soil types, though loamy soil is ideal. Water regularly, especially during dry periods, ensuring the soil remains moist but not waterlogged. Young plants benefit from consistent moisture. Fertilize sparingly, if at all, as too much nitrogen can lead to lush foliage but fewer flowers. Support taller varieties with stakes as they grow to prevent them from falling over.
