#Summer Life Punch Season#My Campanula Flowering Begins. Looking at last year's photos, this year's flowering is about 20 days later than last year, and analyze the reasons, mainly this year's bellflower wintered in the open air, and last year it wintered on a closed balcony. Description: 1 Campanula can be wintered in the open air in this area, and it will not freeze to death. 2 Open overwintering, due to the late onset of growth in spring, postpone the flowering period. Orange stems can be pruned after a wave of flowers and can bloom again until autumn. Therefore, it is better to winter on the balcony if there are conditions, maybe it can bloom a wave of tweed [rose] more than the open-air wintering
