Sowing and Growing Guide

Giant Single Sunflower

Indoor Sowing

  • Start seeds indoors 4-6 weeks before the last expected frost date.
  • Fill individual containers with seed starting mix and sow seeds 1 inch deep, 2-3 seeds per container.
  • Keep the soil moist and at a consistent temperature of 70-75°F.
  • Seedlings should emerge in 7-10 days.
  • Once seedlings have developed their first true leaves, thin them to one per container.
  • Harden off seedlings by gradually exposing them to outdoor conditions over the course of a week.
  • Transplant seedlings outdoors when they are 6-12 inches tall and have at least 2 sets of true leaves.

Outdoor Sowing

  • Sow seeds directly into the garden after the last frost date.
  • Choose a sunny location with well-draining soil that has been amended with compost.
  • Sow seeds 1 inch deep and 6 inches apart.
  • Keep the soil moist but not waterlogged.
  • Thin seedlings when they are 6-12 inches tall, leaving 2-3 feet between plants.

Growing

  • Giant Single Sunflowers prefer full sun and well-draining soil.
  • Water consistently to keep soil evenly moist, especially during periods of drought.
  • Fertilize once a month with a balanced fertilizer.
  • Provide support for the plant as it grows taller, such as staking or using a trellis.
  • Protect from birds and other pests by covering with a netting or using other deterrents.
  • Harvest when the back of the flower head turns yellow and the seeds are plump and brown, usually 80-120 days after sowing.
  • Cut the flower head with a sharp knife, leaving a few inches of stem attached.
  • Dry the flower head in a warm, dry place for several weeks before removing the seeds.
  • Store seeds in a cool, dry place until ready to plant.
