How to Plant Big Flower Coreopsis from Seed

When to Plant Seeds

  • Spring Planting: Sow seeds after the last frost date when the soil is warm.
  • Fall Planting: Sow in late summer or early fall for blooms the following year.

Preparing for Planting

  1. Choose a sunny location with well-drained soil.
  2. Loosen the soil to at least 6 inches deep.
  3. If needed, add organic compost to improve drainage and fertility.

Planting Seeds

  1. Sow seeds directly onto the soil surface.
  2. Press seeds lightly into the soil but do not cover them, as they require light for germination.
  3. Water gently to moisten the soil.
  4. Seeds will germinate within 10-15 days in warm conditions.

Thinning & Transplanting

  • Once seedlings reach 2-3 inches tall, thin them to 12-18 inches apart.
  • If started indoors, transplant after the last frost with minimal root disturbance.

Pro Tip

Deadhead spent blooms regularly to encourage continuous flowering. Once established, it requires minimal watering, making it perfect for low-maintenance gardens. Cut back plants in late summer to promote a second bloom and healthier growth the following season!

Getting to know your Big Flower Coreopsis

Big Flower Coreopsis is a perennial flowering plant known for its bright, daisy-like yellow blooms with deep golden centers. It belongs to the Asteraceae family and thrives in well-drained, sandy, or loamy soil. Native to North America, this plant is drought-tolerant and flourishes in full sun, making it ideal for wildflower gardens and pollinator-friendly landscapes. The plant typically grows 1 to 3 feet tall with slender, lance-shaped green leaves. It blooms from late spring to fall, attracting bees, butterflies, and other beneficial insects. Deadheading spent flowers encourages continuous blooming. Coreopsis is highly adaptable and can withstand poor soil conditions but benefits from occasional watering during prolonged droughts. It is resistant to most pests and diseases, making it a low-maintenance choice for gardens.

What it's used for

1. Ornamental Uses:

  • Perfect for flower beds, borders, and cottage gardens.
  • Works well in wildflower meadows and naturalized landscapes.
  • Looks stunning in container gardens.

2. Pollinator Attraction:

  • Attracts bees, butterflies, and other beneficial insects.
  • Provides an important nectar source for pollinators.

3. Cut Flowers:

  • Long-lasting blooms make beautiful cut flowers.
  • Used in floral arrangements and bouquets.

4. Low-Maintenance Landscaping:

  • Ideal for xeriscaping due to its drought tolerance.

Growth Requirements

Light:

  • Requires full sun for best bloom production (at least 6-8 hours per day).

Soil:

  • Prefers well-drained soil with moderate fertility.
  • Tolerates sandy and rocky soils but does poorly in waterlogged conditions.

Watering:

  • Needs moderate watering during establishment.
  • Once mature, it is drought-resistant and requires only occasional deep watering.

Temperature & Climate:

  • Thrives in warm climates and is hardy in USDA zones 4-9.
  • Can tolerate light frost but may need winter protection in colder areas.

Fertilization:

  • Too much fertilizer can cause excess foliage growth at the expense of flowers.
  • A light application of balanced fertilizer in spring is sufficient.
Maintenance

Watering:

  • Water regularly during the first few weeks of growth.
  • Once established, only water during prolonged dry spells.

Deadheading:

  • Remove spent flowers to encourage continuous blooming.
  • Deadheading prevents self-seeding if you want to control spreading.

Pruning:

  • Cut back plants in late summer to promote a second flush of blooms.
  • In fall, leave some seed heads for birds or trim back for tidiness.

Harvesting & Seed Collection

  1. Harvesting Flowers:
    Cut flowers early in the morning for fresh floral arrangements.
    Use sharp scissors and place stems in water immediately.
  2. Saving Seeds:
    Allow some seed heads to dry on the plant.
    Collect seeds and store them in a cool, dry place for next season.
Pests and Diseases
  • Common Pests: Aphids and leafhoppers can occasionally appear.
    Use neem oil or insecticidal soap if necessary.
