Tips and Tricks for Successfully Cultivating Calibrachoa Superbells® and Million Bells®


If you’re looking for beautiful, vibrant flowers that are relatively easy to care for, Calibrachoa Superbells and Million Bells are excellent choices. These popular plants are celebrated for their bright colors, long blooming period, and compact growth habit. Despite their many benefits, there are a few important factors to consider when growing Calibrachoa to ensure their health and vitality.

One challenge that Calibrachoa plants face is susceptibility to certain diseases. However, by providing proper care and attention, you can minimize the risk of diseases and keep your plants thriving. It’s important to start with healthy plants from reputable sources, as this will greatly reduce the chances of introducing any pathogens. Additionally, provide well-draining potting soil, as overly wet conditions can lead to root rot and other problems.

Fertilizer is essential for promoting robust growth in Calibrachoa. These plants have high nutrient requirements, so it’s crucial to feed them regularly. A balanced, water-soluble fertilizer is recommended, and it’s wise to follow the manufacturer’s instructions for application rates. By fertilizing every two weeks throughout the growing season, you’ll help ensure that your Calibrachoa plants remain healthy and vibrant.

When it comes to growing Calibrachoa, sunlight is another important factor to consider. These plants thrive in full sun conditions, so it’s best to plant them in locations that receive at least six hours of direct sunlight each day. However, certain Calibrachoa cultivars, like Superbells Evening Star, can tolerate some shade. It’s also important to note that Calibrachoa may not perform well in extreme heat or intense sunlight, so provide some afternoon shade if needed.

To keep your Calibrachoa plants looking their best, deadhead them regularly while they’re in bloom. This involves removing the spent flowers, which encourages more blooms and prolongs their overall blooming period. Calibrachoa plants are also well-suited for containers and hanging baskets, so if you want to transplant them, choose a potting mix that drains well and avoid overwatering.

In terms of pests, Calibrachoa plants are generally resistant to most common garden pests. However, they may be susceptible to spider mites, which are tiny sucking insects that can damage the plant’s foliage. Regular monitoring and early intervention can help control spider mites and prevent them from causing significant damage.

When it comes to size and growth habit, Calibrachoa Superbells and Million Bells are relatively compact plants. They typically reach a height of around 6-12 inches and spread about 12-24 inches, making them suitable for both garden beds and containers. These plants are commonly available in a wide range of colors, including pink, red, blue, and yellow, so you can easily find a combination that suits your garden color scheme.

Overall, Calibrachoa Superbells and Million Bells are versatile and beautiful plants that can bring a vibrant display to your garden. With proper care and attention, they can thrive and provide months of blooming enjoyment. Whether you choose to grow them as annuals or perennials, these hardy hybrids are sure to be a standout in your garden.
