Cathedral Bells are grown from seeds. They require a long growing period. As a result, an indoor start is recommended for northern areas of the country. In areas with a long growing season, Cathedral Bells can be directly seeded into your flower garden.
Sow Cathedral Bell seeds early in the season and cover lightly with 1/8″ soil. Keep the soil moist during germination. We recommend heated germination mats for faster germination.
Transplant Cathedral Bell plants into your garden, after the last frost date for your area. Space plants 8-10″ apart. Provide something for them to grow on for maximum growth potential. They will tolerate a little crowding. If growing in hanging planters, space them a little closer.
Days to Germination: Cathedral Bell seeds germinate in 10 to 14 days.
Cathedral Bells tolerate a variety of soils. For maximum growth potential, provide a rich soil with plenty of organic matter. Soil should drain well. Add a general purpose fertilizer when planting them, then once a month after that.
Once your Cathedral Bells are established, they should grow well and vine out at a fast pace. Watering during dry periods is important to sustain fast growth and big, bright blooms.
