Water: Dahlia 'Blue Bell' thrives in moist environments and requires consistent hydration, ideally through weekly watering. It adapts well between moist soil and humidity, supporting its robust growth and vibrant blooms, particularly during the active growing season when soil moisture is crucial.

Fertilize: For dahlia 'Blue Bell', monthly fertilization with balanced 10-10-10 or 8-8-8 NPK during growth promotes strong blooms. Use half the dose to prevent overfeeding. Adjust in dormancy and water soil before and after application. Seasonal changes affect nutrient uptake; reduce in colder months for optimal performance.

Pruning: Prune dahlia 'Blue Bell' in early spring to support growth by removing dead stems and cutting back to healthy nodes. Pinch tips later for bushier growth. Regular deadheading boosts flower production, while pruning helps maintain size and health, leading to extended blooming periods.

Propagation: Dahlia 'Blue Bell' is best propagated from tubers. Divide tubers in the offseason, ensuring each piece has an eye. Allow cut surfaces to dry before planting in well-draining soil with eyes facing up. Maintain moisture without overwatering to support healthy growth.
