1. Insufficient light: Campanula likes a warm, humid and sunny environment. If it grows in the shade for a long time, it will not bloom. If you want it to bloom, you need to make sure you have 8 to 10 hours of light every day.
2. Improper fertilization: Campanula can grow and bloom in rock soil. However, if a lot of nitrogen fertilizer is applied during the maintenance, it will not bloom, but flowering will be ignored, so more phosphorus fertilizer should be added.
