Water: Dahlia 'Thomas A. Edison' prefers consistently moist soil, requiring weekly watering. Originally from wet environments, it thrives outdoors. Mulching is beneficial as it retains moisture and regulates temperature, essential for optimal water uptake and plant health.

Fertilize: Dahlia 'Thomas A. Edison' thrives in fertile soil, requiring liquid fertilizer every 10-15 days initially, shifting to phosphate-potassium later. Fertilization ceases when flower buds color, and should avoid high temperatures. Signs of nutrient imbalance include light leaves for deficiency and scorched edges for excess.

Pruning: Dahlia 'Thomas A. Edison' features large, vibrant blooms. Prune in early spring to encourage growth and reduce disease. Thin overcrowded areas for airflow, pinch stems for bushiness, and deadhead regularly to prolong blooms. Use clean, sharp tools to maintain health and vigor.

Propagation: To cultivate dahlia 'Thomas A. Edison', propagate using healthy tubers cut to include an eye. Plant after the last frost when soils warm. Allow cut surfaces to callus to prevent rot. Ensure regular watering, well-draining soil, and use mulch to support early growth and robust development.
