As needed
  • water dropWater

    Million Bells should be watered thoroughly, allowing the top inch of soil to dry out between waterings. They typically need water every few days, but this can vary based on temperature and humidity. A good approach is to check the soil moisture every other day and water when necessary. During hot summer days, they may need daily watering. Provide approximately 16 ounces of water for small pots or up to 1 gallon for larger containers every time you water, ensuring even saturation.

  • sunLight

    Million Bells thrive in full sun to partial shade. They do best when they receive at least 6 hours of direct sunlight a day. Place them in a spot where they will be exposed to morning sunlight and get some afternoon shade, particularly in very hot climates.

  • thermometerTemperature

    Million Bells prefer temperatures between 55 and 85 degrees Fahrenheit. They can tolerate a minimum temperature of around 50 degrees Fahrenheit at night and maximum daytime temperatures up to around 90 degrees Fahrenheit. However, consistently high temperatures above this range can stress the plant.

  • scissorsPruning

    Million Bells should be pruned to encourage bushiness and to remove spent flowers, which promotes continuous blooming. Lightly prune or pinch back the stems every few weeks during the growing season. The best time to prune is in late winter or early spring before new growth begins.

  • broomCleaning

    As needed

  • bambooSoil

    Million Bells thrive in a well-draining soil mix with a pH between 5.5 and 6.5. An ideal soil recipe would include a mix of peat moss, perlite, and compost to ensure good aeration and moisture retention. Regular feeding with a balanced, water-soluble fertilizer will support healthy growth.

  • plantRepotting

    Million Bells should typically be repotted every year to replenish the soil. However, since they are often grown as annuals, repotting can also coincide with replacing the plant each season. Ensure the new pot is only slightly larger than the previous one.

    Million Bells prefer moderate to high humidity levels but are quite adaptable. They perform well in typical outdoor humidity but can also tolerate lower humidity levels without significant issues.

  • circleLife cycle

    Calibrachoa, commonly known as Million Bells, begins its life cycle as a seed where, after germination, it develops roots and a shoot that emerges from the soil. The seedling grows into a vegetative state characterized by robust leaf growth, establishing a strong root system and stem development. The plant then enters a flowering phase, triggered by appropriate light and temperature conditions, producing the distinctive blue-violet blooms of the 'Aloha Classic Blue Sky'. After pollination, often facilitated by insects, the flowers develop into seed capsules containing numerous tiny seeds, which when mature, are dispersed by wind or other means. If not deadheaded and if growing conditions permit, Calibrachoa will continue to flower over an extended period, often from spring until the first frost in temperate climates. Following seed dispersal, and as seasonal conditions become less favorable, the plant enters senescence, where growth slows and it may eventually die, although many Calibrachoa varieties are perennial in warmer climates or can be overwintered indoors in colder regions.

      Spring to Summer

    • The most popular method of propagation for the Calibrachoa, commonly known as million bells, is through softwood cuttings. This is typically done in spring to early summer when the plant's new growth is just maturing and semi-ripe. A cutting of about 4 to 6 inches (10 to 15 cm) should be taken just below a node and ideally should have a few leaves. The lower end of the cutting is then dipped in rooting hormone powder to encourage root development and planted in a well-draining soil mix. The cutting should be kept under high humidity, either by covering it with a plastic bag or placing it in a propagation chamber, and kept in indirect sunlight until roots have developed, which often takes a few weeks. Once the plant has a robust root system, it can be transplanted into a larger pot or into the garden.
