• Ideal Growing Conditions: Prefers warm soil and moderate temperatures, between 70°F–85°F (21°C–29°C).

Planting Details

• Seed Depth: Plant seeds 1–2 inches deep.
• Spacing: Space plants 18–24 inches apart to allow room for growth and the large flower heads.
• Soil Requirements: Prefers well-drained, slightly acidic to neutral soil with a pH of 6.0–7.5.
• Sunlight: Full sun is essential for the best growth and largest flowers.

Care Instructions

Watering

• Watering Needs: Sunflowers require consistent watering, especially during dry spells. Keep the soil moist but not waterlogged. Water deeply, particularly during dry periods, to support strong root development.

Fertilization

• Fertilization: Sunflowers are heavy feeders. Apply a balanced fertilizer (e.g., 10-10-10) during planting and again when the plant reaches 2 feet tall to promote robust growth.

Weeding and Mulching

• Weeding: Keep the area around sunflowers weed-free to reduce competition for nutrients and water.
• Mulching: Mulch around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature.

Staking and Support

• Support: Due to their height, it’s advisable to stake the Mongolian Giant sunflowers to prevent them from being damaged by wind. Use a sturdy wooden or metal stake to provide support.

Pest and Disease Control

• Pests: Sunflowers are generally resistant to most pests, but they can attract aphids and birds. Use insecticidal soap for aphid control, and place netting over the seeds to protect them from birds.
• Diseases: Keep an eye out for fungal diseases like powdery mildew. Ensure good air circulation and avoid overhead watering to minimize disease risks.

Harvesting

Maturity

• Harvesting Time: The seeds are ready for harvest 70–90 days after planting, when the petals start to fall off, and the back of the flower head turns yellow and dry.

Harvesting Method

• How to Harvest: Cut the flower heads off when they are fully mature, but leave a few inches of stem for handling. Hang them upside down in a cool, dry area to finish drying, then remove the seeds.

Storage

• Short-Term: Store sunflower seeds in an airtight container in a cool, dry place for up to 6 months.
• Long-Term: For long-term storage, sunflower seeds can be frozen after drying to preserve freshness.

Culinary Uses

• Snacking: Sunflower seeds can be roasted and salted for a delicious and nutritious snack.
• Baking: Add sunflower seeds to breads, muffins, or granola for added crunch and flavor.
• Bird Feed: The seeds are an excellent source of food for wild birds, especially during the colder months.
