What is Calibrachoa?

Calibrachoa looks well in borders and containers. Hanging baskets are a good choice for growing million bells because the plant sends flowers on a trail, making an attractive display as calibrachoa flowers come in a variety of colors and patterns.

It can grow up to 8 inches tall. The plant produces blooms all summer long and in fall in moderate climates until the first frost. Whereas in tropics, it blooms in winter and spring.

How to Grow Calibrachoa

Propagation

It can be easily propagated from seeds or cuttings. To propagate it from cuttings take several 4-8 inch long cuttings without blooms. Plant them in a pot after removing the bottom leaves in a well drained potting mix.

Keep the cuttings at a temperature around 70 F, away from direct sunlight and keep the soil moderately moist. After cuttings have outgrown the existing pots, plant them in bigger pots or on the ground.

Location

For prolific blooms, growing calibrachoa in full sun is required as they bloom less in shade. Although some varieties can grow in part shade too.

Requirements for Growing Calibrachoa

Soil

Soil for growing calibrachoa must be loose, well-drained, rich and permeable. They prefer fast-draining potting soil.

Watering

Water million bells when the first 2 inches of soil seems barely moist or dry. It is best to water less as overwatering causes root rot. Water slowly and deeply, soaking the soil to the depth of roots. Keep the leaves dry to avoid fungal diseases.

Fertilizer

Fertilize regularly, every other week using fertilizer specific for flowering annual plants. Also, mix slow-release balanced fertilizer in soil when planting.

 Calibrachoa Care

Calibrachoa care is similar to petunia. It doesn’t require special attention and blooms prolifically.

Pinching

Pinch young plant to promote bushier growth. Also, prune long and leggy branches to encourage healthy branches and divert the plant’s energy into the right direction.

Mulching

Apply a layer of mulch all over the surface to prevent the growth of weeds and to retain moisture. This will also protect the plant from temperature fluctuations in winter.

Deadheading

Remove faded flowers to foster the emergence of new blooms. This will also prevent the deterioration of the plant.

Pests and Diseases

Avoid overwatering, it stresses the plant, restrict its growth, and promotes root rot. Calibrachoa is less sensitive to pests than petunias but might be attacked by whiteflies, aphids, and slugs.
