Starting from Seed

Black Eyed Susan seeds germinate readily without special treatment. Warm to moderate soil temperatures optimize germination and seedling establishment.

When to Sow:

  • Indoors: Start seeds indoors 6–8 weeks before last spring frost. Keep seedlings in warm to moderate conditions (65–75°F) with bright light.
  • Outdoors Direct Sow: Direct sow in spring after frost danger has passed. Plant seeds on soil surface with light cover.
  • Warm Conditions Helpful: Warm soil (65–75°F) speeds germination, though Black Eyed Susan is quite flexible with temperature ranges.
  • Light Exposure Helpful: Seeds benefit from light exposure during germination. Press lightly into soil surface rather than burying deeply.

Sowing Method:

  • Press seeds lightly onto prepared soil surface or seed-starting mix. Seeds are small and should barely be covered with soil.
  • Germination: Keep soil consistently moist but not waterlogged. Black Eyed Susan seeds typically germinate within 7–14 days at warm to moderate temperatures (65–75°F).
  • Light Helpful: Provide bright indirect light from germination onward. Good light promotes healthy seedling development.

Seedling Care: Once seedlings develop true leaves, provide bright light and warm temperatures. Seedlings are easy to grow and very forgiving. Thin seedlings to proper spacing (12–18 inches apart) when 3–4 inches tall. Transplant outdoors after frost danger passes into full-sun locations with well-draining soil.

Planting & Care

Black Eyed Susan thrives in full sun with average, well-draining soil and minimal care requirements.

  • Site Selection: Choose full-sun locations receiving 6–8 hours of direct sunlight daily. Black Eyed Susan excels in borders, cutting gardens, wildflower meadows, and any sunny location.
  • Soil Preparation: Tolerates average to poor soil with good drainage. Well-draining soil is essential to prevent root rot. Avoid overly rich soil that promotes excessive foliage.
  • Spacing: Space seedlings or thin direct-sown plants to 12–18 inches apart to allow proper growth and development of vigorous tall plants.
  • Watering: Water seedlings and young plants to establish. Once established, moderate watering is sufficient. Avoid overwatering; established plants are drought-tolerant.
  • Fertilizing: Avoid heavy fertilization. Black Eyed Susan performs better with minimal nutrients. Excessive fertilizer reduces flower production.
  • Maintenance:
    • Deadheading: Deadhead spent flowers regularly to encourage continuous blooming and extend the flower season, or leave flowers for self-seeding.
    • Heat Excellence: Black Eyed Susan thrives in hot conditions and actually performs better in hot summers than cool-weather plants.
    • Cut Flower Harvesting: Harvest flowers regularly for fresh arrangements encouraging continuous flowering and preventing seed development.
    • Staking Support: In exposed locations, use light staking or support to help tall plants in wind and heavy rain.
    • Pollinator Support: Allow flowers to bloom creating essential pollinator resources and supporting garden ecosystems.
