Water: Dahlia 'Polka' requires ample water due to its large leaves but is sensitive to overwatering. During drought, water promptly, ensuring good drainage in rain. Early seedlings need less water, while later growth demands more, ideally watered at sunrise or sunset.

Fertilize: Dahlia 'Polka' thrives in fertile soil. Apply a diluted nitrogenous fertilizer every 10-15 days initially, transitioning to phosphate-potassium late in growth. After flower bud emergence, fertilize every 7-10 days, stopping once color appears. Monitor leaves for signs of nutrient deficiency or excess.

Pruning: Dahlia 'Polka' features vibrant blooms and thrives with proper care. Prune in early to late spring, remove dead stems, and pinch back tips for bushiness. Regularly trimming spent blooms enhances flowering. Use clean tools to prevent disease and ensure good air circulation for robust growth.

Propagation: Propagation methods for dahlia 'Polka' include root division, cutting, and sowing. Root division is effective, producing about five seedlings per tuber. Cutting is preferred for faster rooting, requiring moist sandy soil and temperatures above 25℃. Sowing leads to blooming in 1-2 years.
