Flowering Months
Water regularly until Canterbury bells plants are fully established. On exposed sites, support the tall flower stems with garden canes. After flowering, cut back the plants to remove faded Canterbury bells flowers and promote a second flush of blooms. Campanula medium will self-seed if the flower heads are left intact.
Pot up campanula plants into pots of free-draining compost, and grow them on in frost free conditions until large enough to plant outside. When all risk of frost has passed and plants are well grown, acclimatise them to outdoor conditions over 7 to 10 days. Grow Canterbury bells outdoors in any moist, fertile, well drained, non-acidic soil. Campanula medium will thrive in sun or semi shade, but the dainty bell-flowers will last longer in a slightly shaded position.
