Canterbury Bellflower

Common Alaska Harebell requires watering twice a week in the spring and summer months. Ensure the soil remains moist but not overly wet. Water the plant from the bottom, allowing the plant to soak up the moisture as it needs it. In the months of fall and winter, water the plant less often, about once a week. Make sure to feel the soil before watering; if the soil feels dry, it is time to water. Avoid overwatering the plant. Avoid any excess moisture around the crown of the stem as this may cause the plant to rot.

Common Alaska Harebell requires full sun for at least 6 hours a day. They prefer cooler climates with temperatures ranging from -40°F (-40°C) to 80°F (27°C). The plant is quite frost-tolerant and can survive in temperatures as low as -40°F (-40°C). In the summer months, the Alaska Harebell requires more sun and should ideally receive 8 to 10 hours of sunlight each day. In the winter months, when the days are shorter, 4 to 6 hours of direct sunlight on most days should be sufficient.

Common Alaska Harebell (Campanula lasiocarpa) should be pruned twice a year. In the springtime, prune the plant after the flowers have finished blooming, removing any dead or damaged stems or branches. In the late summer, cut back remaining stems to encourage new growth for next year's crop of flowers. For established plants, prune the stems back to a height of 6 to 8 inches. For new planted plants, prune the stems back to a height of 4 inches. This will help encourage the growth of new stems and improve the structure of the plant.
