Growth Stages

1

Germination & Seedling

1-2 weeks

Tiny seedlings emerge with fine, thread-like cotyledons and feathery foliage characteristic of coreopsis

Keep soil moist but not wet until germination (7-10 days). Provide bright light to prevent leggy growth. Thin seedlings to proper spacing early.

2

Vegetative Growth

3-4 weeks

Plant develops bushy, mounding habit with fine, delicate foliage; no flowers yet

Pinch back stem tips when 4-6 inches tall to encourage branching and bushier form. Water moderately. Avoid over-fertilizing.

3

Flowering Onset

2-3 weeks

First flower buds appear; plant continues branching while buds develop

Maintain consistent watering without overdoing it. Deadhead spent flowers to encourage more blooms. Full sun essential for prolific flowering.

4

Peak Bloom

6-10 weeks

Abundant bicolor yellow and red flowers cover the plant in a showy display

Deadhead regularly to prolong blooming season and maintain neat appearance. Reduce watering further if established. No fertilizer needed; lean conditions produce more flowers.

5

Seed Set & Decline

Variable; extends until frost or heat stress

As temperatures rise (in heat) or photoperiod changes, flowering may slow; seed heads form if flowers aren't deadheaded

Allow some flowers to set seed for self-sowing next year if desired, or continue deadheading to extend bloom. In mild climates, may persist into fall or next season.

Common Pests

  • Spray with water to dislodge; use neem oil or insecticidal soap if severe. Avoid excessive heat stress.

  • Spray with water or insecticidal soap; beneficial insects usually control populations. Avoid over-fertilizing.

  • and

    Handpick, use diatomaceous earth, or set beer traps. Less of an issue in well-draining conditions.

  • Ensure good air circulation, avoid overhead watering, prune lower foliage. Spray with sulfur or neem if needed.

Harvest Tips

Coreopsis Tequila Sunrise is grown for ornamental display and is not harvested in the traditional sense. Pinch or cut stems when 4-6 inches tall to encourage bushiness.
