These biennial plants are a delightful addition to any outdoor space, with their charming blooms that come in a range of colors from white to violet. In this comprehensive guide, we will cover everything you need to know to successfully grow and care for Canterbury bells.

Canterbury Bells: An Overview

Before we dive into the specifics of caring for Canterbury bells, let’s first understand a bit more about these lovely plants. Canterbury bells are biennial plants, meaning they grow quickly, bloom in two years, and then die. They have an upright form and produce numerous bell-shaped flowers that are not only visually stunning but also emit a sweet fragrance.

Where Do Canterbury Bells Thrive?

Canterbury bells thrive best in the northern United States, as they prefer cooler climates and do not fare well in the heat of southern states. They require full sunlight to grow, along with moist, well-drained soil. Additionally, using a nutrient-rich fertilizer will ensure that your Canterbury bells bloom healthily.

Canterbury Bells Care Tips

Now, let’s delve into the main care requirements for growing and maintaining Canterbury bells.

Light

Canterbury bells flourish when exposed to four to six hours of full sun daily. While they can tolerate partial sun, full sun is ideal for optimal growth and blooming.

Soil

Ensure that your Canterbury bells are planted in well-drained, moist soil. They thrive in loamy or sandy soil, with a pH level ranging from neutral to alkaline. However, near-neutral pH is best for these plants.

Water

It’s crucial to water your Canterbury bells regularly during the growing season. Be careful not to overwater them, as they are sensitive to both drought and flooding. Maintaining good moisture retention in the soil is essential for their health.

Temperature and Humidity

Canterbury bells prefer cooler climates and might require shade in hotter environments. Ideal temperatures for these plants range from 60-80°F, with temperatures exceeding 80°F potentially harming their health.

Fertilizer

In spring, feed your Canterbury bells with a nutrient-balanced fertilizer. A low-nitrogen 5-10-5 NPK fertilizer is recommended. After fertilizing, water the soil thoroughly to ensure the nutrients reach the plant’s roots. Incorporating compost into the soil can also increase fertility and improve drainage.

Types of Canterbury Bells

Canterbury bells belong to the bellflower family, scientifically known as Campanula medium. Here are some popular varieties of Canterbury bells:
– Campanula medium var. calycanthema alba
– Campanula medium ‘Bells of Holland’
– Campanula medium ‘Champion Pink’
– Campanula medium Dwarf Bella Mix
– Campanula medium Double Melton Mix

Pruning and Propagating Canterbury Bells

To keep your Canterbury bells healthy and thriving, it’s essential to prune them regularly. Additionally, propagating these plants can help you ensure a continuous supply of beautiful blooms.

Pruning

Remove dead foliage and pinch or cut fading flowers to prune Canterbury bells. If the plant becomes too large, don’t hesitate to prune excess flowers, even if they seem healthy. Light pruning throughout the summer can encourage new growth.

Propagating

The best way to propagate Canterbury bells is by sowing seeds. Since they are biennials, it’s recommended to plant new seeds yearly to ensure continuous blooming. Canterbury bells are typically grown in flower beds, ideally in the second row of a three-row bed, staggered by height.

How to Grow Canterbury Bells From Seeds

If you’re starting from seeds, begin planting them indoors during the winter and transplant them outdoors in the spring for optimal growth.

Potting and Repotting

When potting Canterbury bells, use regular potting soil with the addition of some sand for better drainage. Choose a container with drainage holes to prevent waterlogging and consider staking the plant for additional support. Repotting is best done in early spring.

Overwintering

For the first year, it’s advisable to grow Canterbury bells indoors to prepare them for winter. Use a thick layer of mulch and water lightly during frosts. Transplant them outdoors in the spring for continued growth.

Common Pests and Plant Diseases

While Canterbury bells are relatively low-maintenance, they can still be susceptible to pests and diseases. Some common issues to watch out for include aphids, mites, slugs, snails, root rot, powdery mildew, and rust. Ensure early treatment of any infestations to protect your plants.

Encouraging Blooms in Canterbury Bells

Canterbury bells are cherished for their stunning flowers that attract pollinators like hummingbirds. To ensure abundant blooms, consider the following tips:

Bloom Months and Duration

Canterbury bells typically bloom from May to July, offering at least three months of colorful blooms from spring to summer. These plants live for two years, with the second year showcasing their signature bells.

Flower Characteristics

The bell-shaped flowers of Canterbury bells come in shades of pink, blue, white, or purple, emitting a sweet fragrance often likened to mint. Proper care and adequate sunlight are key to encouraging more blooms.

Deadheading and Maintenance

Deadheading spent flowers can promote continuous blooming in Canterbury bells. Collecting mature seed pods can help reseed your flower bed annually for ongoing growth.

Common Issues with Canterbury Bells

Despite being relatively easy to grow, Canterbury bells can face some challenges common to bellflowers. Look out for discoloration and overcrowded flowers, and take preventative measures to keep your plants healthy.

Discoloration

Fungal diseases can cause yellowing or browning of leaves in Canterbury bells. To prevent this, avoid overwatering and ensure good air circulation around the plants.

Overcrowding

The abundance of flower spikes in Canterbury bells can sometimes lead to overcrowding and stem collapse. Support the plant with stakes and prune excess growth to maintain its health.
