Seedling (Weeks 1-3)
3 weeksTiny seed germinates with cotyledons emerging. First true leaves appear as growth accelerates.
Keep soil consistently moist but not saturated. Provide bright light and maintain 70-75°F. Thin seedlings if overcrowded. Begin fertilizing at half strength once true leaves appear.
Vegetative/Establishment (Weeks 4-6)
2-3 weeksPlant develops branching stems and robust foliage. Compact, bushy form begins to establish. Multiple growing points develop.
Pinch growing tips once or twice to encourage bushier, more prolific growth. Gradually acclimate transplants to outdoor conditions. Water consistently and feed with balanced fertilizer weekly at half strength.
Early Flowering (Weeks 7-9)
2-3 weeksFirst flower buds form and open along branching stems. Purple flowers begin creating visible color.
Transition to full-strength fertilizer if not already. Ensure adequate sunlight for best color development. Continue watering deeply but allow brief drying between waterings. Remove any dead or diseased foliage.
Peak Blooming (Weeks 10+)
8-12+ weeks until frostMassive profusion of purple trumpet flowers covers the plant. Dense, mounding habit fully achieved. Flowers cover most foliage.
Kabloom varieties require minimal deadheading due to continuous bloom genetics. Water deeply 2-3 times weekly depending on heat. Feed every 7-10 days with flowering fertilizer (higher potassium). Remove yellowed lower leaves if desired for tidiness.
Decline/End of Season (Frost approach)
Variable, 2-8 weeks depending on climateFlowering slows as temperatures drop below 55°F. Plant growth and bloom production diminish. Frost damage occurs at 32°F or below.
Reduce watering as growth slows. Stop fertilizing. In zones 9-11, cut back by half and provide winter protection for potential spring regrowth. In cooler zones, compost spent plants after first frost.

Common Pests
-
Spray leaves with water to dislodge. Use insecticidal soap or neem oil if severe. Improve air circulation and avoid overhead watering.
-
Use yellow sticky traps. Spray with insecticidal soap or neem oil. Remove heavily infested leaves. Encourage natural predators.
-
Spray with strong water jet. Use insecticidal soap, neem oil, or horticultural oil. Plant nearby beneficial insect-attracting flowers.
-
Improve air circulation. Spray with sulfur or potassium bicarbonate fungicide. Avoid overhead watering. Remove severely infected leaves.
Uses
Not for consumption
CulinaryCalibrachoa is ornamental and not edible. Do not consume flowers or foliage. [source]
Container gardening and visual appeal
HouseholdKabloom Purple excels in hanging baskets, window boxes, mixed containers, and as cascading accent plants. The prolific purple blooms provide continuous color and texture from spring through fall. [source]
Low-maintenance landscape color
HouseholdThe self-cleaning bloom habit means minimal maintenance compared to other calibrachoa varieties. Ideal for busy gardeners or areas where deadheading is impractical. [source]
Pollinator attraction
WildlifeThe abundant small trumpet flowers attract bees, butterflies, and other beneficial pollinators throughout the season, supporting local ecosystems. [source]
Floral arrangements and design
CraftThe delicate purple flowers can be harvested for small floral arrangements or used fresh in floral designs, though they have a relatively short vase life compared to larger flowers. [source]
Harvest Tips
Calibrachoa is an ornamental flower, not harvested for consumption. Deadheading is typically unnecessary with Kabloom varieties, as they are self-cleaning and continuous bloomers. For extended vase life if cutting flowers, cut early morning and place in fresh water immediately. Pinching off spent flower clusters can encourage denser branching.
Fun Facts
- 🌱 Calibrachoa is sometimes called 'million bells' because of the sheer abundance of tiny flowers produced on a single plant—one well-grown specimen can produce hundreds of blooms simultaneously.
- 🌱 The Kabloom series was specifically bred for self-cleaning and continuous blooming without deadheading, making it significantly lower maintenance than traditional calibrachoa varieties that require regular flower removal to maintain blooming.
- 🌱 Despite their delicate appearance, Kabloom varieties are remarkably heat and drought-tolerant once established, making them ideal for hot summer climates where other flowers struggle.
