Care Instructions for Gomphrena ‘Fireworks’:

Light Requirements: Plant Gomphrena ‘Fireworks’ in full sun to ensure optimal growth and prolific blooming. It needs at least 6 hours of direct sunlight daily.

Soil and Watering: This plant thrives in fertile, well-drained soil. While it is drought-tolerant once established, providing moderate moisture will result in better flower production. Allow the soil to dry slightly between waterings to prevent root rot.

Fertilization: A light application of balanced, slow-release fertilizer in early spring will support vigorous growth and abundant flowering. Avoid excessive fertilization, as it can lead to lush foliage at the expense of blooms.

Pruning: ‘Fireworks’ does not require deadheading, as it continuously produces new blooms throughout the growing season. However, removing spent flowers can encourage more prolific blooming.

Pests and Diseases: This cultivar is generally resistant to pests and diseases but can occasionally be affected by common garden issues such as aphids, thrips, and fungal infections like Botrytis or Cercospora Leaf Blight. Regular monitoring and appropriate treatment with insecticidal soap or fungicides can keep these problems in check.

Winter Care: In regions with mild winters, Gomphrena ‘Fireworks’ can act as a perennial. However, in colder climates, it is treated as an annual. To ensure continued presence in the garden, consider saving seeds or propagating plants indoors.

Propagation

Gomphrena ‘Fireworks’ is easily propagated from seed:

  1. Sowing Seed Indoors:
    • Start seeds indoors 6-8 weeks before the last expected frost.
    • Sow seeds ¼ inch deep in seed-starting mix.
    • Keep the soil evenly moist and maintain a temperature of around 70°F (21°C).
    • Seedlings typically emerge in 10-14 days.
    • Once seedlings have two pairs of true leaves, transplant them into individual pots to encourage strong root development.
    • Harden off the seedlings by gradually exposing them to outdoor conditions before planting them in the garden after the last frost.
  2. Direct Sowing in the Garden:
    • Sow seeds directly in the garden after the danger of frost has passed.
    • Prepare the soil by removing weeds and incorporating organic matter.
    • Sow seeds evenly and cover with ¼ inch of fine soil.
    • Keep the soil moist until seedlings emerge.
    • Thin seedlings to stand about 10 inches apart once they are 1-2 inches high.
