Calibrachoa, often referred to as "Million Bells," is a vigorous and versatile flowering plant prized for its abundant, bell-like blossoms that brighten gardens throughout the warmer months. It’s an excellent choice for gardeners seeking colorful, low-maintenance plants that thrive in containers, hanging baskets, and garden beds. This article provides an easy-to-follow guide on growing and caring for Calibrachoa, including sections on planting, watering, fertilizing, pruning, and tips for troubleshooting common issues.
Planting Calibrachoa
Planting Calibrachoa is an exciting step that sets the stage for a lively color show in your garden. To ensure optimal growth, follow these guidelines:
- Choosing the Right Location: Calibrachoa prefers full sun, requiring approximately six to eight hours of sunlight per day. Choose a sunny spot in your garden or planters that receive ample light.
- Soil Requirements: Ensure the soil is well-draining, as Calibrachoa roots are prone to rot in overly moist soils. Incorporate organic matter, such as compost or peat moss, to enhance drainage and nutrient quality.
- Planting Technique: Space the plants about 6 to 10 inches apart to allow for their spreading habit. When planting in containers, provide sufficient room for root expansion and choose pots with drainage holes.

Watering Calibrachoa
Calibrachoa requires a careful watering routine to sustain its vibrant blooms without succumbing to root rot. Here’s how to strike the right balance:
- Frequency: Water Calibrachoa consistently, preferably in the morning, but avoid overwatering. While the plant likes moisture, it does not tolerate soggy soil.
- Indicators of Water Needs: Check the soil moisture by sticking your finger a couple of inches into the soil. If it feels dry, it’s time to water.
- Container Considerations: Containers may require more frequent watering due to faster soil drying. Adjust your watering schedule based on the weather and soil conditions.

- Type of Fertilizer: Use a balanced, slow-release granular fertilizer or a liquid fertilizer specifically formulated for blooming plants.
- Frequency: Apply fertilizer every two to three weeks during the growing season for robust flower production.
- Application Method: If using granular fertilizer, sprinkle it around the base of the plant and gently work it into the soil. For liquid varieties, follow the manufacturer's instructions on dilution and application.
