Million Bells Calibrachoa Superbells Pink = 'Uscali11' (PBR) (Superbells Series)

Water

Million Bells should be watered when the top inch of the soil feels dry to the touch, which could vary from every few days to once a week, depending on climate conditions and the pot size. Generally, in containers, they may need water more frequently, especially in warmer weather. Use a gentle stream of water to avoid disrupting the soil and roots, providing enough water until it runs through the drainage holes. This could be about one to two gallons for a large hanging basket every watering session, ensuring consistent moisture without waterlogging the soil.

Light

Million Bells thrive in full sun, which means they require at least 6 to 8 hours of direct sunlight daily for optimal growth and flowering. The best spot for these plants would be in a location where they are exposed to unfiltered sunlight, though they can tolerate very light shade. However, too much shade can reduce blooming and make the plant leggy.

Temperature

Million Bells perform best in temperatures that range from 55 to 65 degrees Fahrenheit at night and between 65 and 85 degrees during the day. They can tolerate cooler temperatures down to about 35 degrees but should be protected from frost. The ideal conditions for consistent flowering and growth would be maintaining the temperature within these ranges as much as possible.

Pruning

Pruning Million Bells is often not necessary, but deadheading or pinching back the tips can promote bushier growth and enhance flowering. If the plants become leggy or blooms diminish, prune them back to encourage new growth. The best time for pruning is mid-season or when you notice the plant looks tired and needs rejuvenation. Prune lightly every few weeks to maintain shape and flower production.

Cleaning

As needed

Soil

Million Bells thrive in well-draining potting soil with a pH between 5.5 and 6.5. Mix with peat moss, perlite, and compost to improve drainage and fertility for optimal growth.

Repotting

Million Bells should be repotted annually, usually in the spring, into fresh soil to replenish nutrients and give roots space to grow.

Humidity & Misting

Million Bells prefer moderate to high humidity levels but are adaptable to different humidity conditions as long as soil moisture is properly maintained.

Suitable locations

• Indoor

  Place in bright, indirect light; maintain regular watering.

• Outdoor

  Full sun to partial shade; protect from strong winds and extreme heat.

• Hardiness zone

  9-11 USDA

Life cycle

The Calibrachoa Superbells Pink, also known as Mini Petunia, begins its life as a seed, germinating in warm soil with plenty of sunlight and moisture. Upon germination, the seedling emerges with cotyledons, followed by true leaves, and develops into a vegetative plant. As it matures, the Mini Petunia establishes a robust root system and begins to grow rapidly, producing a dense foliage of small, lance-shaped leaves. Flowering occurs in the late spring to early summer when daylight hours are long, with the plant producing numerous pink, petunia-like flowers that attract pollinators. After pollination, seeds develop, which will disperse naturally or can be collected for propagation. In the fall or with the onset of colder temperatures, the plant will enter a period of dormancy or may die if it is not perennial in the climate zone where it is grown.

Propogation

  Spring to Summer

• The most popular method of propagating Calibrachoa Superbells Pink, which is known for its lovely pink blooms and is a patented variety, hence propagation may be restricted by the plant breeders' rights. However, for those varieties where propagation is allowed, the common method would be through softwood cuttings. This involves taking a 4 to 6-inch cutting from the tip of a stem, removing the lower leaves, and dipping the cut end into a rooting hormone. Then the cutting is placed in a well-draining potting mix. The environment should be kept humid, which can be accomplished by covering the pot with a plastic bag and placing it in indirect light. Roots typically develop within a few weeks, at which point the new Calibrachoa plant can gradually acclimate to less humid conditions before being planted outdoors.
