📏

Spacing: 12-18 inches apart; 2-3 plants per 10-inch hanging basket inches

📅

Days to maturity: 30-45 days to first blooms from transplant

🌱

Planting depth: Plant at soil level; do not bury stems

Soil

Growth Stages

Transplant Establishment

7-10 days

Young plants with 2-4 true leaves, compact branching structure becoming visible

Keep consistently moist but not waterlogged. Place in bright light to encourage branching. Pinch tips once to promote bushiness if desired.

Vegetative/Branching

2-3 weeks

Rapid stem and foliage development with increasingly dense branching; no flowers yet

Begin light feeding with balanced fertilizer. Ensure full sun exposure. Continue consistent watering.

Flower Bud Formation

1-2 weeks

First tiny buds appear at branch tips; plant becomes fuller and more mounding

Switch to a higher phosphorus fertilizer to encourage blooming. Maintain even moisture and full sun.

Flowering & Blooming

8-14 weeks (until frost or extended heat stress)

Abundant small trumpet flowers (5-20mm) continuously produced from early buds through first frost; flowers open daily and fade by evening

Deadheading optional due to prolific flower production. Continue regular feeding every 1-2 weeks. Water deeply during heat waves. Remove any diseased leaves promptly.

Late Season/Decline

Variable; until frost

Flowering may slow in extreme heat (95°F+) or as day length shortens in fall; plant toughens for cooler nights

Reduce watering slightly if in heat dormancy. Light shearing can rejuvenate bloom in cooler fall weather. Prepare for frost damage.

Companion Planting

Common Pests

Spray undersides of leaves with insecticidal soap or neem oil weekly; yellow sticky traps; encourage beneficial insects
Increase humidity, mist foliage; spray with water forcefully; use miticide if severe; avoid excessive heat stress
Spray with strong water stream; use neem oil or insecticidal soap; introduce ladybugs
and
Remove by hand in early morning; copper tape barriers around containers; beer traps; diatomaceous earth

Uses

🏠

Harvest Tips

Million Bells is ornamental; no harvest needed. Deadheading is optional—the MiniFamous series is bred for continuous flowering without pinching. Remove spent flower clusters occasionally for neatness, but the plant naturally sheds old blooms and produces new ones constantly. Pinch stems back by 1/4 inch in midsummer if growth becomes too lanky.

Fun Facts

🌱 Million Bells produces hundreds—sometimes thousands—of flowers over a season, yet requires minimal deadheading compared to regular petunias, making it ideal for low-maintenance container gardens.
🌱 The 'MiniFamous' series is a deliberate calibrachoa hybrid bred for compact size, dense branching, and improved vigor compared to older calibrachoa varieties.
🌱 Calibrachoa is sometimes called 'Million Bells' due to its prolific flowering habit, but it's actually a different plant from the petunia (though closely related); it features smaller flowers, tougher foliage, and greater heat tolerance.
