How to grow calibrachoa

Calibrachoa, also called Million Bells, looks much like a miniature petunia. In fact, calibrachoa is related to the petunia. These petite flowers work well in borders and containers. Hanging baskets are a good choice because the plant will send down a trail of blossoms, making for an attractive display. Calibrachoa plants have many small flowers that bloom from spring until the first frost of the year and grow well in all U.S. planting zones.

Purchase calibrachoa seedlings from a nursery. Look for full plants that have begun to flower and have no wilted stems.

Plant the seedlings 8 to 12 inches apart in rich, well drained soil where they will receive full sun. Cover the root completely. Make sure containers have plenty of drainage holes.

Keep the soil moist but not soaking wet. Water regularly during summer heat when the soil dries out quickly.

Fertilise container plants weekly with a nitrogen rich flower fertiliser. Bedded plants only need to be fertilised monthly.


Calibrachoa sheds its spent flowers on its own, making it a low maintenance plant.


It is illegal to propagate calibrachoa because it is a patented hybrid, so purchase all plants from nurseries.
