Germination Instructions:

  1. Prepare the soil: Choose a location with well-draining soil and total sun exposure. Loosen the soil to a depth of 12 inches, and mix in a 2-4 inch layer of compost or aged manure to improve fertility and drainage.
  2. Sow the seeds: Plant seeds 1 inch deep and 6 inches apart in rows 2-3 feet apart. Water the seeds thoroughly after planting.
  3. Germination time: Mammoth Sunflower seeds typically germinate in 7-10 days. Keep the soil consistently moist but not soggy.

Growing Instructions:

  1. Thinning: Once seedlings have developed two sets of true leaves and reached a height of 3 inches, thin them to 1.5-2 feet apart to give them room to grow.
  2. Watering: Water your sunflowers consistently, providing 1-2 inches weekly. Be sure to water at the base of the plant to avoid wetting the foliage and encouraging disease.
  3. Fertilizing: Apply a balanced, slow-release fertilizer at planting time and again when the plants are about half their expected height. Avoid excessive nitrogen, leading to weak stems and smaller flower heads.
  4. Staking: For exceptionally tall sunflowers, provide support using stakes or garden structures to prevent wind damage.

Harvesting Instructions:

  1. Seeds: Harvest sunflower seeds when the back of the flower head turns brown and the seeds' outer shells have blackened. Cut the flower head off, leaving a few inches of stem attached. Remove seeds by rubbing two flower heads together or picking them out individually. Allow the seeds to dry in a well-ventilated area before storing them.
  2. Flowers: For cut flowers, harvest sunflower blooms when the petals begin to open. Cut the stems early in the morning and place them in a water container to prolong the vase's life.
