How to Grow

First, choose a location that receives full sun and has well-draining soil. Sunflowers need at least six hours of direct sunlight each day to grow. Once you have selected the perfect location, prepare the soil by loosening it to a depth of at least 12 inches. Add compost or well-rotted manure to the soil to improve its nutrient content. Next, sow the seeds directly into the soil after the danger of frost has passed. Plant the seeds about 1 inch deep and 6 inches apart. Water the seeds well after planting and keep the soil moist but not waterlogged. As the sunflowers grow, they will need regular watering, especially during dry spells. Apply a balanced fertilizer once a month to promote healthy growth. Deadhead the sunflowers by removing spent blooms to encourage more flowers to grow. Finally, be prepared to stake the sunflowers as they grow taller. Mammoth Gray Stripe Sunflowers can grow up to 8 feet tall, and strong winds can easily topple them over. Use bamboo stakes or other support systems to keep the sunflowers upright. Save seeds once mature and dry.
