Green Thumb Tip

Keep your Campanula plant away from doorways and air vents. Hot or cold drafts will scorch its leaves.

Get more blooms. Pinch off spent flowers as soon as you notice them to encourage more blooms.

Keep your plant. It's a perennial and will flower year after year. Cut stems back (close to the base of the plant) in late fall or early winter, after flowering season. It doesn't need a cold season in winter. Give it the same temperature and light as usual. Keep the soil on the dry side until you see new growth in spring, then resume with normal watering.

To repot...or not. Repot campanula plants when their roots are visible at the surface of the soil. Wait till winter or early spring to repot -- never while it's blooming.
