Bellflower sowing needs to suit the species and local season. Keep the seed tray labeled and monitor moisture without saturating the medium.
Read the bellflower seed packet first
Campanula includes annual, biennial and perennial plants, and their sowing instructions differ. A biennial selection may form a leafy rosette before flowering in a later season. Do not promise flowers thirty days after every sowing.
Prepare a clean, manageable seed tray
Use an appropriate seed medium and follow the packet's advice on covering, light and temperature. Fine seed is easy to bury too deeply. Label the sowing so slow germination is not confused with an empty tray.
Keep moisture even without saturation
Water gently and maintain suitable conditions while seedlings emerge. Ventilate any cover as needed and remove it appropriately after germination. A permanently sealed, soaked tray encourages weak growth and deterioration.
Pot on before crowding becomes severe
Handle seedlings by suitable leaves rather than squeezing delicate stems, and preserve their small roots. Increase light and exposure gradually as plants grow. Space them for their eventual habit, allowing time for establishment before expecting the mature flowering display.
