Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist, especially during active growth and flowering. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.
Reduce watering slightly in cooler weather or when the plant is dormant.
Deadhead spent flowers regularly to encourage continuous blooming and prevent self-seeding if not desired. At the end of the flowering season, you can cut back the plant to the ground to tidy it up and prepare it for overwintering.
Canterbury-bells are best propagated by seeds sown in early spring indoors or directly in the garden after the last frost. They can also be propagated by division of established clumps in spring or autumn.
Seeds may require stratification.
Annuals typically do not require repotting. Perennial varieties, if grown in containers, can be repotted every 1-2 years in spring when they become root-bound.
Use a well-draining potting mix and a pot only slightly larger than the current one.
