Choose a sunny location: Mongolian Giant Sunflowers require full sun, so choose a spot that gets at least 6 hours of direct sunlight each day.
Prepare the soil: Loosen the soil to a depth of at least 12 inches and mix in compost to provide nutrients for the growing plants.
Plant the seeds: Sow the seeds 1 inch deep and 6 inches apart in rows or in groups of 3-4 seeds. Space the rows at least 2-3 feet apart to allow for the large size of the mature plants.
Water regularly: Keep the soil moist but not waterlogged. Water the plants deeply once a week, or more often in hot, dry weather.
Provide support: As the plants grow, they may need support to prevent them from bending or breaking. Place stakes or poles around the plants and tie the stems to the supports with soft ties or twine.
