Sunflowers grow best in locations with full sun. They are remarkably tough and will grow in any kind of soil as long as it is not waterlogged. They do fine in soils that are slightly acidic to somewhat alkaline (pH 6.0 to 8). Once sunflowers get started, they can tolerate drought as befits plants whose ancestors grew happily in dry prairie regions. They are so easy to grow that they often plant themselves, springing up unbidden beneath a bird feeder.
Pro Tip: Cover and keep watered until seeds sprout in 7 to 10 days.
