flower

Calibrachoa Kabloom Pink is a compact, mounding annual flowering plant prized for its prolific small petunia-like flowers in vibrant pink. This cultivar is self-cleaning and requires minimal deadheading, making it ideal for containers, hanging baskets, and garden borders. It flowers continuously from late spring through first frost with minimal maintenance.

Growing Conditions

☀️

Sun: Full sun, 6-8 hours daily (more sun promotes denser flowering)

💧

Water: Water moderately when top inch of soil is dry. Avoid overwatering, which causes root rot. In containers, may need daily watering in hot weather. Reduce watering in cooler seasons.

📏

Spacing: 6-12 inches apart (depending on container size; 8-10 inches typical for baskets) inches

📅

Days to maturity: 35-45 days to first flowers; continuous blooming thereafter

🌱

Planting depth: Barely cover seeds (they need light to germinate); transplants at same soil level as original pot

Soil

Type: Well-draining potting mix or light, sandy loam soil

pH: 6.0-6.8

Amendments:

Perlite or coarse sand for drainage Compost for organic matter Peat moss or coco coir for moisture retention

Growth Stages

Seedling

7-10 days

Tiny seedlings emerge with delicate oval cotyledons and develop true leaves. Plants are fragile and low-growing.

Provide bright light, maintain warm temperatures (70-75°F), and keep soil moist but not waterlogged. Use a grow light if indoors. Avoid fungal issues by ensuring good air circulation.

Vegetative Growth

2-4 weeks

Plants develop multiple stems and foliage, creating a bushy mound. Leaves are small, narrow, and somewhat waxy in texture.

Pinch back growing tips 1-2 times to encourage branching and a fuller habit. Maintain consistent moisture and provide full sun. Begin fertilizing weekly with balanced or slightly higher nitrogen formula.

Budding

1-2 weeks

Small flower buds form along branch tips. Plant continues expanding in size and density.

Continue pinching if desired for maximum bushiness, though Kabloom is naturally compact. Switch to higher phosphorus fertilizer to support blooming. Ensure full sun and consistent watering.

Flowering

4-5 months (late spring to first frost)

Abundant small pink trumpet-shaped flowers (about 0.75-1 inch diameter) open continuously. Flowers are self-cleaning and drop naturally.

Water consistently as flowering increases transpiration. Fertilize every 7-10 days with bloom-promoting formula (higher potassium). Deadheading is optional but not required. Monitor for pests and diseases.

Senescence/End of Season

Variable, until first frost

As temperatures drop in fall and days shorten, flowering slows and eventually ceases. Foliage may take on reddish tones.

Reduce fertilizing as blooming declines. Plants can be pulled out at first hard frost. In zones 9-11, cut back plants or allow to overwinter for next season.

Companion Planting

Plan your garden →

Plant with:

Dusty Miller Trailing ivy Petunias Bacopa Lobelia Verbena Ornamental grasses Marguerite daisy

Avoid planting near:

Plants requiring dry conditions (excessive moisture competition) Very tall plants that shade it

Common Pests

Spray with neem oil or insecticidal soap; increase air circulation; use yellow sticky traps for monitoring
Mist foliage regularly; spray with neem oil or miticide; maintain humidity around 50-60%
Spray with water jet to dislodge; use insecticidal soap; apply neem oil; encourage beneficial insects
Allow soil surface to dry between waterings; use mosquito dunks in soil; avoid overwatering containers

Uses

🍳

Edible flowers (garnish)

Culinary

Calibrachoa flowers are non-toxic and can be used as delicate garnishes for desserts, salads, and beverages. They add visual appeal and a slightly sweet, subtle flavor. [source]

🏠

Container and basket gardening

Household

The Kabloom Pink cultivar is exceptionally well-suited for hanging baskets, window boxes, and mixed containers. Its trailing mounding habit and prolific blooming make it perfect for summer displays with minimal care. [source]

🏠

Landscape bedding and borders

Household

Plant in mass for striking color in garden beds and borders. The self-cleaning nature and continuous blooming create weeks of vibrant pink color with virtually no deadheading required. [source]

🦋

Pollinator support

Wildlife

The abundant flowers attract bees, butterflies, and hoverflies, providing essential nectar throughout the growing season. This makes it valuable for supporting pollinator populations. [source]

🎨

Cut flower arrangements

Craft

Short sprays of Kabloom Pink flowers can be cut and used in small fresh floral arrangements and posies. Their delicate size works well in miniature or fairy-themed displays. [source]

Harvest Tips

Not typically harvested, but spent flowers are self-cleaning and drop naturally. Pinch back stems occasionally (every 4-6 weeks) to maintain compact shape if desired. Cut back leggy stems to encourage bushier growth. In zones 9-11, cut back to 6 inches in late fall to rejuvenate for next season.

Fun Facts

🌱 Calibrachoa is sometimes called 'Million Bells' because a single well-grown plant can produce hundreds of flowers during its growing season.
🌱 The Kabloom series was specifically bred for self-cleaning flowers and compact growth, requiring significantly less maintenance than older calibrachoa varieties or petunias.
🌱 Calibrachoa is native to South America but is now one of the most popular ornamental annuals in temperate gardens worldwide, thanks to intensive hybridization.
