Planting Instructions
- Timing: Plant Russian Mammoth Sunflower seeds in early spring after the last frost or late summer for the best results. The seeds can be broadcast over the planting area or sown directly into the soil.
- Soil Preparation: Choose a location with full sun and well-draining soil. Loosen the soil to a depth of at least 12 inches and amend it with compost or organic matter to improve fertility.
- Sowing: Plant the seeds 1-1.5 inches deep, spacing them 6-12 inches apart. If planting in rows, leave 2-3 feet between rows to allow the sunflowers ample space to grow. After germination, thin the seedlings to 12-24 inches apart to prevent overcrowding.
- Watering: Keep the soil consistently moist during the germination period. Once established, Russian Mammoth Sunflowers are relatively drought-tolerant, but they will produce the best blooms with regular watering.
- Maintenance: No staking is usually required for Russian Mammoth Sunflowers, but in particularly windy areas, it may be beneficial to provide some support as the plants grow taller. Fertilize sparingly, as excessive nitrogen can lead to excessive foliage growth at the expense of blooms.
Harvesting and Uses
- Seed Harvest: Once the flower heads have matured and the seeds have fully developed, they can be harvested for human consumption or left on the plant as a food source for birds. To harvest, cut the heads off and dry them in a warm, dry place. Once dry, the seeds can be easily removed from the head.
- Ornamental Use: The large, vibrant blooms make excellent cut flowers for arrangements, adding a touch of natural beauty to your home.
