Ideal Temperature

Water: Bonnet bellflower thrives in moderately moist conditions with a preference for humidity and cannot tolerate drought. A weekly watering schedule is ideal. As an outdoor plant, it requires careful attention to water needs during the growing season due to fluctuations in rainfall.

Fertilize: Fertilize bonnet bellflower using a balanced 10-10-10 NPK fertilizer at quarter-strength every four weeks during the growing season. Reduce frequency during dormancy to prevent nutrient overload. Proper dilution and careful application are crucial to avoid root burn.

Pruning: Bonnet bellflower requires regular maintenance including early spring pruning to remove dead or damaged stems. This promotes air circulation, encourages bushier growth, and enhances flower production. Using clean, sharp tools minimizes damage while consistent pruning prevents overgrowth, ensuring a healthy and attractive plant.

Propagation: To propagate bonnet bellflower, sow fresh seeds in prepared soil, ensuring optimal moisture without waterlogging. Sow seeds shallowly for light exposure needed for germination. Once seedlings sprout, thin them to provide adequate space for healthy growth and maturation.

Repotting: Bonnet bellflower, a climbing perennial, benefits from repotting every 2-3 years in early spring for optimal growth. Use a larger container for root expansion and maintain even moisture while avoiding direct sunlight for a week, enhancing its twining habit and bloom display.
