Learning Download: How to Grow Campanula
Campanula, also referred to as bellflowers due to the usually bell-shaped blossoms, have annual, perennial and biennial varieties. Some varieties have blooms shaped like a star or a cup.
Before Planting: Begin Campanula seeds indoors up to eight weeks before the last frost. Plant the seeds in planting cells, placing three to four seeds per cell. Place in a sunny area and keep the soil moist.
Planting: Once seedlings reach 4 inches, you can decide if you want to transplant them outside into the garden. Space the plants 7 inches apart for smaller varieties and 15 inches apart if they are a bigger variety.
Watering: The soil should be kept moist, but not too soggy.
Fertilizer: Feed the Campanula once a month with an 10-10-10 liquid-based fertilizer.
Days to Maturity: Campanula flowers typically aren’t used as cut flowers, but they will produce seed pods in the fall.
Harvesting: Snip off the seed capsules and place them in a paper bag. You can plant the seeds immediately or save them until the spring.
Tips: Some Campanula varieties will not bloom their first year.
