Growth Stages

1

Seedling

2-3 weeks

Tiny plants with 2-4 true leaves; very delicate and small, requiring high humidity and bright light under grow lights

Keep soil consistently moist but not waterlogged. Provide 12-16 hours of bright light daily. Maintain temperatures around 65-75°F. Do not fertilize at this stage.

2

Transplant/Establishment

2-3 weeks

Young plants with 4-8 leaves growing in nursery pots; roots developing and plant becoming more robust

Harden off gradually before planting outdoors. Begin light fertilization with diluted liquid fertilizer. Maintain moist soil and bright light. Pinch tops if plants are getting leggy to encourage branching.

3

Vegetative Growth

3-4 weeks after transplanting

Plant is establishing in garden or container; stems branching and leaf area expanding; foliage is lush and green

Water regularly and maintain consistent moisture. Apply balanced fertilizer every 2 weeks. Deadhead spent flowers to encourage branching and more blooms. Provide full sun exposure.

4

Flowering

8-12 weeks or until frost

Plant produces abundant small pink flowers in clusters; blooms continuously throughout the season

Maintain regular watering—critical during this stage. Switch to fertilizer with higher phosphorus (middle number) to support flowering. Deadhead regularly. Provide at least 6 hours of full sun daily. Watch for pests and diseases.

5

Late Season/Senescence

Continues until first frost (zone dependent)

As temperatures cool and days shorten in fall, flowering may slow; plant appearance remains attractive if maintained

Continue deadheading and watering as needed. Reduce fertilizer frequency. In zones 9-11, plants may survive winter and re-bloom next season if protected or brought indoors.

Uses

🍳

Ornamental garnish

Cut flower arrangements

Craft

The delicate sprays of small pink blooms can be used in miniature or fairy garden-style floral arrangements. Short-lived in the vase but charming in small-scale creative displays. [source]

Harvest Tips

Superbells Pink is grown for continuous ornamental flowers rather than harvest. Deadhead spent blooms regularly by pinching or cutting them off just below the flower stem to encourage more flowering throughout the season. This practice extends the blooming period and maintains plant appearance from planting until frost.

Fun Facts

  • 🌱 Superbells is a hybrid of Calibrachoa species; these flowers are sometimes called 'million bells' because of their prolific flowering habit—a single mature plant can produce hundreds of blooms over a season
  • 🌱 Calibrachoa was only formally described as a genus in 1990 and is relatively new to ornamental horticulture compared to petunias; Superbells was introduced by Proven Winners and has become one of the most popular calibrachoa varieties worldwide
  • 🌱 Unlike petunias, which are self-cleaning, Superbells Pink still benefits from deadheading, but the flowers are so small and numerous that many gardeners allow spent blooms to drop naturally without significant impact on appearance
