If you’re ready to bring these beautiful blooms to your own yard, it’s important you know everything there is to planting, growing, and caring for Campanula flowers.

  • Plant Campanula in well-draining soil and in an area where they can receive partial to full sun. The more direct sunlight Campanula receives, the more blooms it will produce!
  • Campanulas’ long blooming period shows their best colors from late spring until the first frost occurs in early fall. Little maintenance is required to keep these flowers happy. Just water during dry periods and fertilize with an all-purpose (5-10-10 or 10-10-10) garden food once in the spring and once during the mid-summer.
  • Add 2-3 inches of organic mulch around your Campanula after planting, being careful not to mulch directly against the plant (to prevent possible rot). This mulch will help retain moisture, deter weeds from popping up in your garden and help fertilize your beds as it breaks down!
  • Trim dead heads to promote more blooms and prolong the flowering period. Always use small scissors or gardening shears when trimming Campanula to prevent tearing your flower stems.
  • Space Campanula 15-18 inches apart when planting. Because these flowers are a sprawling variety, you should divide congested flowers in spring or fall. Once winter comes, you can cut back your Campanula or let it remain as an over-winter habitat for birds. See this blog post for more information about creating a bird-friendly garden!
  • Be sure to check for pests such as snails, slugs, and aphids who love to nibble on Campanula’s pretty leaves. Moist plant surfaces tend to attract these types of critters, so try irrigating the soil around your flowers when watering.
  • Also check for sickness or disease, which may show up as a fuzzy white coating of powdery mildew on leaves and stems. Prune affected areas from the plant or apply fungicide or horticultural oil in severe cases.
