Calibrachoa, also known as million bells or trailing petunia, is a delicate perennial with flowers in violet, blue, pink, crimson, magenta, yellow, bronze, and white that form mounds of foliage and grow only 3 to 9 inches (7.5-23 cm) tall along trailing stems.
All cultivars of the early 1990s-era plant Calibrachoa are crosses with the original South American species. From spring until the first frost, they blossom frequently. The plant can survive the winter in USDA Zones 9 to 11, and it is typically cultivated as an annual in chilly regions or a perennial in warm ones.
Petunias and calibrachoas belong to the same family, right?
While the two plants are distant cousins in the Solanaceae family, calibrachoa were originally placed in the same genus as petunias until being awarded their own genus.
Do million bells and petunias look alike?
Calibrachoa flowers are sometimes called as “million bells” because to the large number of colorful blooms they generate. Because of its trailing branches, the Calibrachoa is a fast-growing compact annual that thrives in hanging baskets and window boxes. They are a lovely addition to your containers, hanging baskets, window boxes, or garden beds because they are a very heat- and cold-tolerant plant.
Since the blooms of million bells resemble those of a petunia, they are also referred to as wild petunias. However, the blossoms are not sticky like petunias. They come in a variety of hues, including white, yellow, magenta, red, blue, pink, and violet. Butterfly Attraction Million Bells. The thick, emerald leaves are. The stems are between 6 and 8 inches in length, and the flowers are around 1 inch long.
Million Bells are easy to care for: When planting your million bells, mix some excellent compost, like Bumper Crop, and some peat moss into the soil. This will give new plants the ideal soil base for retaining nutrients and water. Use the beneficial mycorrhizae Espoma Bio-Tone soil conditioner as well. This will support the development of a strong root system. Keep them well-hydrated. After that, feed them once a week with liquid Miracle-Gro water soluble fertilizer and once a month with Espoma Flower-Tone.
Million Bells adore the sun, so put them where they will receive full sun to get the most flowers. While afternoon shade is OK, it may hinder blooming, so million bells do best in full sun. Since they can withstand drought, too much water will cause the roots to decay. When planting in containers or hanging baskets, especially during the summer heat of July and August, use the finger test and water when the soil feels dry, which may mean once or twice a day.
Million Bells won’t need their wasted flowers deadheaded; they will continue to bloom. When the branches become long and lanky, don’t be afraid to give them a haircut. After cutting, you can anticipate fresh blooms in a week or so. Long-term, this will result in a plant that is both healthier and more attractive.
A lovely low-maintenance annual to add to your yard is million bells. Your garden will appear to be in a million either in a container, a hanging basket, or your flower bed!
Do Supertunias resemble Calacoas?
Infinite Supertunia Vista Although petunias are mounded, they will also overflow the sides of pots. They are excellent container plants and can be used in combination planters as both fillers and spillers. They are excellent landscaping plants and work best at the front of beds. They are plants with a lot of branches. Their flowers range in size from tiny to very tiny, like a huge Superbells Calibrachoa flower. They are a suitable replacement for Calibrachoa in environments with poor drainage. Petunias are far more tolerant than calibrachoa, which needs good drainage to thrive.
Do I Need to Deadhead?
Calibrachoa Most Million Bells are self-cleaning. That implies that the dead blooms simply fall off and do not require cutting off. Million Bells will, however, continue to look their best with the occasional trim throughout the summer, similar to other annual plants, particularly when they start to get spindly and develop only a few flowers at the tips of their trailing branches.
Why is My Calibrachoa Dying?
Root rot could affect your plant. The biggest issue with million bells is this. And irregular irrigation can be the reason.
The leaves of your plant may appear wilted and may even be brown and withered if it has root rot. This may give the impression that your calibrachoa needs more water, but in reality, it probably doesn’t! Reduce the frequency of watering and let the plant dry out.
Do They Come Back Every Year?
Depending on where you reside. Since calibrachoa is a perennial in USDA hardiness zones 9 to 11, it will flourish all winter long. Calachoa functions as an annual for those of us who live in colder climates.
Can I Propagate Cuttings?
Cuttings of Calibrachoa are simple to grow. However, the majority of cultivars are protected by trademarks, and propagation may be limited or even forbidden. You can find out if it’s okay to grow new plants from cuttings by looking at the plant tag.
For the following year, you can store the seeds from your plants, but it’s possible that they won’t grow. Even though they might not resemble the flower from last summer, you can still grow something lovely!
Can I Overwinter Them?
They can indeed spend the winter indoors. The requirements for care indoors are a little different from the care you gave in the garden.
Bring your plant indoors once the growing season is through. It might benefit from being potted up in new soil. Cut the stalks back and take off any faded blossoms. The moment is right for a significant haircut.
Put the plant somewhere bright, but out of direct sunlight. Give it some time to relax; you won’t need to water as frequently. Every other week, use liquid fertilizer. You can also use a slow-release fertilizer, but only use half the suggested amount. You can use more water and fertilizer as the days get longer and brighter.
Keep an eye out for rot and bugs like aphids and spider mites. Your plant should survive until the time comes to move it into the garden in the spring with any luck and appropriate care.

Petunia Superbells are they?
Super Bells, sometimes referred to as tiny Petunia or Million Bells, are a type of Petunia classified as Calibrachoa. Since their introduction in the 1990s, these plants have pleased gardeners. They are prolific bloomers with a compact, trailing habit and produce an inexhaustible supply of tiny flowers in a wide range of colors. They are ideal for garden beds, patio planters, mixed containers, and hanging baskets. Grow plants in a wet, well-drained soil, letting them dry out between waterings, and fertilize them all during the growth season.
What is the name of the tiny flowers that resemble petunias?
Calibrachoas, sometimes known as million bells, have the appearance of little petunias, yet botanists frequently disagree as to whether they belong to the same genus as petunias or not. Fortunately, gardeners don’t have to worry about their names. They have a wide range of hues and designs, such as stripes, pinwheels, splashes, and speckles, which we may simply appreciate. Single or double calibrachoas, which resemble miniature roses, are available.
Similar to petunias, calibrachoas, which have been domesticated since the early 1990s, like six hours of direct sunlight each day, though they can take moderate shade, particularly in areas with hot summers. If you choose to plant them in containers, use a high-quality potting soil because they require quick-draining soil. If you decide to plant them in your garden, rake any pebbles, roots, and other debris out of the soil. Then add organic material to your soil to enrich it.
How is a Calibrachoa maintained in bloom?
As long as their needs are addressed, calebrachoa will blossom all summer long. The key ingredients for their happiness are sunlight, fertilizer, rich soil, and water. In containers with excellent drainage, they function best.
Does Calibrachoa like sun or shade?
Although they may tolerate some shade, calibrachoa plants blossom best with at least six hours of full light. Without enough light, plants will stretch, fewer flowers will bloom, and the leaves will develop a pale green color.
How do you keep a Calibrachoa blooming?
Calibrachoa plants consume a lot of food. Frequent watering quickly leaches nutrients from the soil, so fertilize frequently to ensure sustained bloom. Use a slow-release granular fertilizer at planting time or use a water-soluble fertilizer every two weeks, refilling as directed.
How often should I water my Calibrachoa?
When the top several inches of soil feel dry, water calibrachoa. They could require daily watering in hot, dry weather because they can dry up quickly. It’s time to water if you stick your finger two inches into the soil and it feels dry. Fill the entire container to the point where liquid drains out the bottom. Between waterings, let the plants dry out a little.
Should I deadhead Calibrachoa?
Calibrachoa don’t need to be deadheaded because they clean themselves. Occasionally pinch back the tips to promote branching, which will result in additional flowers. Cut branches in half and fertilize plants to encourage new growth to revitalize them in the middle of the season.
Diseases and pests:
Root rot or an infection from a Phytophthora species, which can destroy plants, can result from overwatering. After being watered, plants may wilt, which may indicate root rot. Spider mites and aphids can make plants more vulnerable to heat stress.
How are leggy growths of Calibrachoa prevented?
Cut back any stems that have gotten too long or are pressing up on other plants using scissors or pruners. Cut a few branches only.
Check to see whether some mild pruning was sufficient to restore the desired appearance. If not, remove a few more stems until the desired appearance is obtained.
How much time do calacoa last?
One of the quickest rates of novel breeding our industry has ever seen is probably occurring in calibrachoa. There is a lot of variation across series available on the market because each breeding company’s offers have a somewhat distinct breeding focus. Most breeders aim to improve either grower performance or consumer performance, and these two objectives differ significantly. The majority of programs prioritize disease resistance and avoiding sensitivity to pH because these are the two largest issues the crop faces, which are limitations of the original plants from Latin America. After addressing these two problems, breeders then concentrate on plant habit and flower color to finish a series or collection.
Calibrachoa differs from petunia in a number of lovely ways. The distinctive colors and patterns are among the first things that most people notice, but plants can also tolerate extremely dry conditions quite well, grow well in hanging baskets, and are well-adapted to very high light levels. When plants reach consumers, this last characteristic is crucial for their survival. Due to where their plants are developed and chosen before distribution, each breeding company will offer some regional variations. Plants designed for heat tolerance may be somewhat less able to handle early-season cold greenhouses and moist soil conditions than plants bred for heat tolerance in colder climates. The optimal practices for each grower’s environment must be determined through experimentation.
Growing calibrachoa is simple if a few fundamental rules are followed; the rules apply to all series. High light levels, avoiding overwatering, and proper air circulation are the main points to concentrate on. The majority of the species in the genus calibrachoa are native to the rocky slopes of Brazil, which provides a clear indicator of the ideal growing environment for these plants. They thrive when the air in the greenhouse is flowing, have excellent drainage needs, and adore the sun.
When transplanting, be mindful of your watering and use a fungicide: Many farmers run into problems here, especially in the north. Early-season production necessitates low light levels, a chilly greenhouse with permanently damp soil, and typically a closed greenhouse with little internal air movement. It is a recipe for the crop to have issues. The majority of businesses advise a fungicide drench at transplanting to assist reduce the disease risks associated with a cold, slow-growing crop because they are aware that producers will bring material in early and encounter these possible problems. The majority of growers should be obliged to use that fungicide drench due to the numerous issues early season production has been causing the business. When spring is prolonged and gloomy, these issues occur more frequently. When transplanting, safeguard yourself with a fungicidal drench.
Learn how the pH of your soil affects growth. A healthy soil pH must always be maintained. The ideal pH range for all series is between 5.5 and 6.0. Most people can handle a pH as low as 5.0, thus it is acceptable to allow the pH to drop a little. Growers experience issues when the pH rises too high. Yellowing and chlorosis are the first symptoms of high pH because at higher pH levels (over 6.0), plants lose their capacity to absorb iron from the soil. If this continues for too long, the plants will start to weaken, lose vitality, and have less branching. Maintaining pH between 6.0 and 6.5 is crucial. If the issue is identified early enough, additional foliar iron can be supplied, but if the soil pH isn’t corrected, you’ll be fighting the issue the entire crop.
Fertilization guidelines advise using 150 to 200 ppm of fertilizer at transplant and 200 to 250 ppm during production. Early growth is increased by higher feed rates, but to prevent overwatering, use a stronger feed rather than more frequent feeding and watering. Utilize a balanced fertilizer containing no more than 25 to 30 percent nitrogen that is ammoniacal. If you see that your stretch is getting too great, lower the ammonium levels. Utilize fertilizers based on the quality of your water after having it tested by a reliable lab. The majority of calibrachoa benefit from having more iron in their fertilizer (1 to 2 ppm).
Growing Temperature: 55°F to 65°F (13°C to 18°C); plants can be cultivated at a lower temperature, but the finishing period will be longer. Plants can also be kept compact by using a negative DIF to finish the harvest, with days at 55°F and nights at 62°F to 65°F. This will raise the overall quality of the crop. When calibrachoa develop a strong root system, they may often be transplanted into cooler environments. Plants that have been hardened off can be planted outside in the spring. The majority of calibrachoa may withstand a mild frost +/- 28oF as long as they have hardened off.
Light Levels: Constantly High (+ 5,000 ftc) to encourage compact growth and quicken the process of natural branching. Superbells thrive in direct sunlight both inside and outside the greenhouse.
Average water needs, but if in doubt, let plants somewhat dry out (do not dry to wilting stage). Keep in mind that they like rocky slopes and cliffs and need sufficient drainage. Avoid overwatering at all costs, especially in chilly, low-light situations. Once the roots have developed through the new mix, start letting the media dry between irrigations. Once a plant has been established in new media, it is crucial to avoid overwatering it.
Information on planting and timing: Most flowers appear between weeks 9 and 10. Make plans appropriately.
Final Hours:
For pots 6 inches in diameter and smaller, pinch while transplanting. Or, on the 4.5-inch pot size, a single spray of Florel at 500 ppm can take the place of no-pinch. Soft pinching at planting and trimming around the pot shortly before hanging are necessary for hanging baskets and pots larger than 6 inches. A B-Nine/Cycocel spray (2500/750) tank mix spray or a Sumagic spray at 5 to 10 ppm also works nicely. Branching will be encouraged by a 500 ppm Florel spray on baskets and bigger pots. Due to warmer production circumstances, growers in the South and Southwest may require slightly greater rates.
Pest and Disease Management: Start each growing season with new, sterile growing media and a clean, disinfected greenhouse, as you would with any crop. Bleach, Greenshield, and ZeroTol are some effective disinfectants. A broad-spectrum fungicide treatment at planting as a prophylactic measure is a fantastic idea. Overwatering is the most frequent reason for calibrachoa issues.
Pythium, Phytophthora, and Thielaviopsis are toxic to calibrachoa. Superbells are more resistant to these illnesses than other calibrachoa, although keeping the right pH (5.5 to 5.8) and using appropriate hygiene techniques can assist solve issues. Increased airflow, efficient water use, and healthy soil porosity are also essential. Check your plants frequently for aphids, which can be troublesome. Make sure to inspect high-hanging hanging baskets. With pots placed up in the rafters, it can be simple to neglect to check for bug issues.
The most frequent pests of calibrachoa are fungus gnats, followed closely by aphids. In addition to weakening plants and making them more vulnerable to disease, fungus gnat larvae can crawl up stems and kill plants. Never let algae or standing water grow on surfaces like tables, floors, or media. Checking for larval populations is easy and effective using a wedge of potato placed on top of the media. Utilize larvaecides to eradicate any larvae populations and regulate moisture in the media.
When blooms are developing, thrips are most common. In order to introduce the crop, first control the population.
It is simple to grow calibrachoa, but you must keep a close eye on your pH, avoid overwatering, and produce a clean crop. Avoid the early season syndrome, which is characterized by limited airflow, dim lighting, and wet medium. To ensure that plants receive the nutrients they require but not the extra water from frequent watering, you can fertilize at greater levels and limit watering. Work with a wet grower if you have one of your own to prevent issues with a calibrachoa crop.
Most individuals stop having any issues with this crop once the growing season begins, the light becomes more abundant, and the temperatures rise. Having enough of this wildly successful and dynamic annual becomes a challenge. Simply adhere to these straightforward guidelines and make plans for the following year to ensure that your plants are growing properly from the start to produce better income and less headaches.
