Water: Dahlia 'Kelvin Floodlight' requires ample water due to its large leaves but is sensitive to both drought and overwatering. Watering is essential during dry spells, and good drainage is crucial in wet conditions. During early growth, water daily on sunny days, increasing amounts as dahlia 'Kelvin Floodlight' matures. Water preferably at dawn or dusk.

Fertilize: Dahlia 'Kelvin Floodlight' thrives in fertile soil and requires a thin liquid fertilizer every 10-15 days initially, favoring nitrogen. After budding, switch to every 7-10 days until color appears. Excessive heat or certain leaf symptoms indicate inappropriate fertilization levels.

Pruning: Dahlia 'Kelvin Floodlight' features large blooms and sturdy stems. Prune in early to late spring to enhance growth and flowering. Remove dead stems, trim for shape, and pinch new tips for bushier plants. Pruning prevents diseases, promotes air circulation, and ensures a healthier, more attractive display.

Propagation: Dahlia 'Kelvin Floodlight' can be propagated through root division, cutting, and sowing. Root division involves planting tubers at 15℃ for budding, yielding approximately five seedlings per tuber. The cutting method offers faster rooting in moist sandy soil, with optimal temperatures above 25℃. Sowing typically results in blooms 1-2 years post-sowing.
