Planting Velvet Queen Sunflower Seeds
When to Plant: Sow seeds outdoors in late spring after the last frost when soil temperatures have warmed to 70-75°F (21-24°C).Southern Seeds+1Pinetree Garden Seeds+1
Site Selection: Choose a location that receives full sun, as sunflowers thrive in bright, direct sunlight.
Soil Preparation: Sunflowers prefer loose, rich, well-drained soil with a pH between 6.0 and 7.5. Incorporate compost or well-rotted manure to enrich the soil.
Planting Depth and Spacing:
- Depth: Plant seeds ½ to 1 inch deep.
- Spacing: Space seeds 6 to 12 inches apart for single-stem varieties and 18 to 24 inches for branching types.Pinetree Garden Seeds
Direct Sowing:
- Prepare the soil by removing weeds and debris.
- Create shallow furrows and place seeds at the recommended depth and spacing.
- Cover seeds lightly with soil and water gently.
- Maintain soil moisture until germination, which typically occurs in 10 to 14 days.
Starting Indoors:
- Start seeds indoors 4 to 6 weeks before the last expected frost.Pinetree Garden Seeds
- Use biodegradable pots to minimize transplant shock.Pinetree Garden Seeds
- Provide consistent moisture and maintain soil temperatures around 70-75°F (21-24°C).
- Transplant outdoors after the last frost when seedlings have at least two true leaves.Pinetree Garden Seeds

Support: While Velvet Queen sunflowers have sturdy stems, providing support can prevent them from falling over, especially in windy areas or when bearing multiple blooms.
Care and Maintenance
- Watering: Sunflowers are drought-tolerant once established but benefit from regular watering during dry spells. Deep watering encourages strong root systems.
- Fertilization: Over-fertilizing can lead to excessive foliage growth. If soil fertility is low, apply a balanced, slow-release fertilizer at planting time.
- Mulching: Apply a layer of mulch around the base to retain soil moisture, suppress weeds, and regulate soil temperature.
- Pest and Disease Control: Sunflowers are generally resistant to pests and diseases. However, watch for common issues like aphids or powdery mildew. Ensure proper spacing for air circulation and avoid overhead watering to reduce disease risks.
Harvesting and Seed Saving
Cut Flowers: Harvest blooms when the petals are fully open but before they start to wilt. Use sharp scissors or pruning shears, and place stems immediately in water to prolong freshness.
Seed Saving:
- Allow flower heads to mature on the plant until the back of the head turns yellow.
- Cut the head and hang it upside down in a dry, well-ventilated area to fully dry.
- Once dry, rub the seeds from the head and store them in a cool, dry place in an airtight container.
