How to Protect Canterbury Bells

Canterbury bells, also known as campanula or bellflower, can be annual, biennial or perennial. About 300 species exist, and depending upon the variety, these flowers' heights range from 3 inches to 5 feet tall with tubular to saucer-shaped blossoms. Due to the wide variety of species, care for Canterbury bells varies, and some flowers require protection from wind, pests and disease.

Step 1

Stake taller varieties of Canterbury bells to protect them from blowing over in strong winds. Use a plant support purchased from a garden center or use twine to secure the plant to a bamboo cane or dowel rod.

Step 2

Sprinkle a ring of diatomaceous earth, crushed eggshells or wood ash around the flowers to protect Canterbury bells from slugs and snails.

Step 3

Prevent rust fungus from developing on Canterbury bells. Plant them in a garden site with good air circulation. Direct water toward the roots of the plant and avoid getting the leaves wet. Remove any affected plants or plant parts to prevent them from spreading to other plants. Do not add these to the compost. The Connecticut Agricultural Experiment Station states, "Although not usually necessary, applications of fungicides can be made when new growth emerges in the spring."
