Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with two cotyledons (seed leaves); very delicate

Keep soil consistently moist but not waterlogged. Provide bright indirect light. Maintain temperatures 65-70°F for best germination.

2

Seedling

3-4 weeks

True leaves emerge and plant develops compact rosette form; growth is slow

Provide bright light to prevent legginess. Thin seedlings to proper spacing. Begin fertilizing weekly with dilute balanced fertilizer.

3

Vegetative

4-6 weeks

Dense mounding growth with deep green foliage; no flowers yet

Pinch back growth tips once or twice to encourage bushier form. Maintain consistent watering and fertilize every 2 weeks. Watch for pests.

4

Budding & Early Flowering

2-3 weeks

Flower buds form at branch tips; first flowers begin to open in coral-pink

Continue regular fertilization; switch to bloom-boosting fertilizer (higher phosphorus). Deadhead spent flowers to encourage more blooms.

5

Peak Bloom

6-12 weeks (or until frost)

Profuse coral-pink flowers cover the mounding plant; continuous blooming

Deadhead regularly for continuous flowering. Water deeply during heat. Apply light mulch around base. Continue balanced fertilizing every 2-3 weeks.

Harvest Tips

Telstar Coral is grown for ornamental flowers rather than harvest. Deadhead spent blooms regularly by pinching or cutting faded flowers just below the spent bloom to encourage continuous flowering throughout the season.

Fun Facts

  • 🌱 Dianthus is often called 'pinks' not because of their color, but because of the serrated, pink-edged petals of some varieties—the common name comes from the 'pinked' (pinking shears-cut) appearance of the petal edges.
  • 🌱 Telstar is an All-America Selections (AAS) Award-winning series, meaning it has been trialed and proven superior in gardens across North America for performance, ease of growth, and reliability.
  • 🌱 Unlike many annual flowers, dianthus have a pleasant spicy clove-like fragrance that intensifies on warm, sunny days, making them charming additions to cutting gardens near seating areas.
